Website Launch Checklist: 58 Essential Things to Do Before and After Publishing

In 2026, the web has more than 1.5 billion websites, but fewer than 200 million are active, which makes quality, reliability, and technical readiness more important than simply publishing a new site. 

Mobile also accounts for 53.65% of global web usage, so launch checks now need to cover mobile layout, speed, accessibility, tracking, security, and SEO from the start. 

A complete website launch checklist helps reduce broken forms, indexing problems, slow pages, security gaps, and poor user experience before they affect traffic, leads, or sales. 

This checklist covers 58 essential website launch tasks across design, content, SEO, speed, security, functionality, accessibility, and post-launch maintenance.

Download the free website launch checklist PDF below and use it while reviewing your website before and after publishing. 

Website Launch Checklist Overview

A proper website launch process has two major stages:

Stage	Purpose
Before Launch	Fix design, content, SEO, speed, security, and functionality issues before the website goes public.
After Launch	Monitor indexing, tracking, redirects, uptime, backups, broken links, and real user behavior after publishing.

The safest website launch process is not handled by one person only. A developer, designer, SEO specialist, content editor, and business owner need to review different parts of the website before final approval.

Design and UX Checklist Before Website Launch

Design and UX checks confirm that the website looks professional, works across devices, and gives users a clear browsing experience. 

A launch-ready website must be easy to read, easy to navigate, and easy to use on mobile, tablet, and desktop.

1. Test Responsive Design on All Devices

Responsive design means the website layout adjusts properly across mobile, tablet, laptop, and desktop screens. 

A site that looks good on desktop but breaks on mobile is not ready for launch.

Test every important page at different screen widths, especially from 320px upward. Many users still browse from small mobile devices, so the mobile layout needs special attention.

Check these elements on each screen size:

• Header and navigation menu
• Hero section
• Text blocks
• Images and banners
• Buttons and CTAs
• Forms
• Tables
• Footer
• Popups
• Product cards or service cards

A responsive website must not have horizontal scrolling, overlapping text, broken buttons, hidden content, or images that push outside the screen.

2. Check Cross-Browser Compatibility

Different browsers render websites slightly differently. A website that works in Chrome may show layout or script issues in Safari, Firefox, or Microsoft Edge.

Before launch, test the website on all major browsers:

• Google Chrome
• Mozilla Firefox
• Safari
• Microsoft Edge

Browser testing is important for menus, sliders, forms, animations, checkout pages, and interactive elements. 

Safari testing deserves extra attention because CSS, video formats, sticky elements, and form fields sometimes behave differently on Apple devices.

A launch-ready website must provide the same core experience across browsers, even when small visual differences exist.

3. Keep Fonts and Typography Consistent

Typography affects readability, brand quality, and user trust. Inconsistent font sizes, random heading styles, and mismatched spacing make a website look unfinished.

Check whether the same font family is used across the site unless the brand guideline allows multiple fonts. Review headings, body text, buttons, captions, menus, form labels, and footer text.

A basic typography review includes:

• H1, H2, H3, and paragraph font sizes
• Line height for readability
• Font weight consistency
• Letter spacing
• Text alignment
• Button text style
• Mobile font scaling

Good typography creates a clear reading flow. Users must understand which text is most important without thinking too much.

4. Check Color Contrast for Accessibility

Color contrast affects readability, especially for users with low vision or users browsing in bright light. Poor contrast also makes buttons, menus, and important messages harder to notice.

Body text needs enough contrast against the background. A common accessibility benchmark is WCAG AA, where normal body text needs a minimum 4.5:1 contrast ratio and large text needs at least 3:1.

Check contrast for:

• Body text
• Heading text
• Button text
• Navigation links
• Form labels
• Placeholder text
• Error messages
• Footer links
• Text over images or banners

Avoid light gray text on white backgrounds, low-contrast buttons, and text placed directly over busy images without overlays.

5. Set the Website Favicon

A favicon is the small brand icon that appears in browser tabs, bookmarks, search results, and mobile shortcuts. A missing favicon makes a website look incomplete and less professional.

Prepare favicon files in common formats and sizes:

• 16x16px
• 32x32px
• Apple touch icon
• Android icon where needed

The favicon must match the brand identity and display clearly at small sizes. Avoid detailed graphics that become unreadable in browser tabs.

After setting the favicon, clear browser cache and test it in different browsers.

6. Create a Custom 404 Error Page

A 404 page appears when users visit a broken or unavailable URL. A default 404 page gives a poor experience and often causes users to leave the website.

A custom 404 page helps users recover from the error and continue browsing.

A useful 404 page includes:

• Clear message that the page is not available
• Link to the homepage
• Link to main services or product categories
• Search box if the site has search functionality
• Contact link for support
• Friendly but professional tone

The goal is not only to show an error. The goal is to guide users back to useful pages.

7. Check for Broken UI Elements

Broken UI elements make users lose trust quickly. Buttons that do not work, dropdowns that fail to open, modals that freeze, and forms that break create launch-day problems.

Review all interactive elements before publishing:

• Buttons
• Navigation menus
• Dropdown menus
• Sliders
• Tabs
• Accordions
• Popups
• Modals
• Forms
• Filters
• Search bars
• Cart buttons
• Login buttons
• Social sharing buttons

Test these elements on desktop and mobile. Mobile testing is especially important because hover effects, sticky bars, and popups often behave differently on touch screens.

8. Review White Space and Visual Hierarchy

White space helps users scan the page without feeling overwhelmed. Visual hierarchy tells users what to read first, what action to take, and where each section begins or ends.

A page with poor hierarchy often has too much text, weak headings, repeated buttons, cluttered sections, and no clear focus.

Review each page and ask:

• Is the main heading visible immediately?
• Is the most important CTA easy to find?
• Are sections separated properly?
• Are paragraphs short enough?
• Are images supporting the content?
• Are buttons placed near relevant content?
• Is the page easy to scan?

Good visual hierarchy improves user experience and conversion because visitors understand the page faster.

9. Make Touch Targets Large Enough

Touch targets are clickable areas such as buttons, menu items, icons, and links. Small touch targets create frustration on mobile devices because users tap the wrong item or fail to tap anything.

A practical target size is at least 44x44px for important buttons and links. Also leave enough spacing between clickable items.

Check touch targets for:

• Mobile menu icons
• CTA buttons
• Form submit buttons
• Social icons
• Footer links
• Product quantity buttons
• Checkout buttons
• Filter buttons
• Close icons on popups

Mobile usability is a major part of website launch quality. If users struggle to tap, the website is not ready for launch.

Content and Copy Checklist Before Website Launch

Content checks confirm that the website has accurate, complete, and user-friendly information. 

A website with strong design but weak copy still feels unfinished. Before launch, every page must be reviewed for clarity, accuracy, grammar, brand tone, and conversion intent.

10. Proofread All Website Text

Proofreading removes spelling errors, grammar mistakes, formatting issues, and awkward sentences before the website goes public. A business website with visible writing mistakes looks less trustworthy.

Proofread these content areas:

• Homepage copy
• Service pages
• Product pages
• About page
• Contact page
• Blog posts
• FAQs
• Footer text
• Form labels
• Button text
• Popup messages
• Checkout text
• Error messages

Do not rely only on automated tools. Grammarly, Hemingway, or built-in spell checkers help, but manual review is still needed. A human editor understands context, brand tone, and meaning better than software.

11. Remove Placeholder Content

Placeholder content is one of the most common website launch mistakes. Dummy text, sample images, test products, demo posts, and fake team profiles must be removed before publishing.

Search the full website for:

• Lorem ipsum text
• Dummy images
• Sample blog posts
• Demo products
• Placeholder team members
• Testimonials copied from templates
• Temporary pricing
• “Coming soon” text in finished sections
• Default WordPress content
• Theme demo links

Placeholder content damages trust and may also get indexed by search engines if not removed quickly after launch.

12. Check All CTAs

CTA means call to action. Website CTAs guide users toward the next step, such as contacting the business, booking a call, requesting a quote, downloading a file, signing up, or buying a product. Before launch, check every CTA text and destination.

Examples of CTA issues:

• Button goes to the wrong page
• Button text does not match the offer
• Contact button opens a broken form
• “Book Now” leads to the homepage
• Pricing CTA opens an empty page
• Multiple CTAs create confusion
• CTA is hidden on mobile

Each CTA must be clear, relevant, and connected to the user intent of that page.

13. Verify Contact Information

Wrong contact information directly affects leads, calls, bookings, and customer trust. Before launch, verify all business contact details across the website.

Check:

• Business phone number
• Email address
• Office address
• Business hours
• WhatsApp number
• Contact form recipient email
• Google Maps embed
• Social media profile links
• Footer contact details
• Schema contact information

Contact details must be consistent across the website, Google Business Profile, social media pages, and business directories. Inconsistent contact data creates confusion for both users and search engines.

14. Update the Copyright Year

The footer copyright year is a small detail, but it affects how fresh and maintained the website feels. A new website with an outdated copyright year looks neglected.

Check the footer copyright format. 

For example: Copyright © 2026 Brand Name. All rights reserved.

For websites that update automatically, confirm that the dynamic year function is working correctly. For static sites, update the year manually before launch.

15. Publish Legal Pages

Legal pages build trust and support compliance. Most business websites need basic legal pages before going live, especially if they collect user data, use cookies, sell products, run ads, or collect payments.

Important legal pages include:

• Privacy Policy
• Terms and Conditions
• Cookie Policy
• Refund Policy for e-commerce websites
• Shipping Policy for online stores
• Disclaimer where needed

A Privacy Policy is especially important when the site uses contact forms, analytics tools, pixels, email marketing, payment gateways, or third-party tracking scripts.

Legal pages must not remain empty, copied blindly, or filled with template placeholders. The content needs to match the website’s actual data collection and business process.

16. Prepare Blog or News Content

A blog or news section must not look empty at launch if it is part of the website structure. An empty blog creates a weak first impression and gives search engines fewer content signals.

For a business website, publish a few useful posts before launch. These posts may cover:

• Industry guides
• Service explanations
• FAQs
• Company updates
• Case studies
• Buying guides
• How-to resources
• Product education

For SEO-focused websites, initial blog content helps build topical relevance from the start. The first posts need proper titles, meta descriptions, internal links, images, headings, and author details.

A blog section is only useful when it has a clear content purpose. Do not add a blog only because the theme includes it. Use it when the business has a plan to publish helpful content regularly.

SEO Fundamentals Checklist Before and After Website Launch

SEO checks help search engines crawl, understand, index, and rank the website properly. A website can look perfect visually, but if basic SEO settings are missing, Google may struggle to process the site correctly.

SEO setup must begin before launch, not after the website goes live. Meta titles, descriptions, canonical tags, headings, URLs, alt text, schema, sitemap, robots.txt, analytics, and search console settings all work together to create a clean search foundation.

17. Set Unique Meta Titles and Meta Descriptions

Meta titles and meta descriptions help search engines and users understand what each page is about. They also affect click-through rate from search results.

Every important page needs a unique meta title. Avoid using the same title across multiple pages because duplicate titles make pages harder to differentiate in search results.

A good meta title usually includes:

• Primary keyword
• Brand name where needed
• Clear page topic
• 50 to 60 characters where possible

A good meta description usually includes:

• Main service, product, or page value
• Search intent match
• Natural keyword use
• 150 to 160 characters where possible
• Clear reason to click

Example format:

• Meta title: Website Design Services in Dhaka | Brand Name
• Meta description: Get professional website design services in Dhaka for business websites, landing pages, e-commerce stores, and SEO-ready websites.

Do not stuff keywords. A meta title must sound natural and explain the page clearly.

18. Configure Canonical URLs

Canonical URLs tell search engines which version of a page is the main version. This helps prevent duplicate content problems when similar or duplicate URLs exist.

Duplicate URLs often appear because of:

• HTTP and HTTPS versions
• www and non-www versions
• URL parameters
• Pagination
• Filter pages
• Tracking links
• Printer-friendly versions
• Product category sorting
• Duplicate landing pages

A canonical tag points search engines toward the preferred page.

Example:

<link rel=”canonical” href=”https://example.com/service-page/” />

Canonical tags are especially important for e-commerce websites, blog archives, location pages, product variations, and websites with filterable content.

Before launch, check that every indexable page has the correct canonical URL pointing to itself or to the correct main version.

19. Generate an XML Sitemap

An XML sitemap lists important website URLs for search engines. It helps Google and Bing discover pages faster, especially on new websites or large websites.

A sitemap should include important indexable pages such as:

• Homepage
• Service pages
• Product pages
• Category pages
• Blog posts
• Location pages
• Important landing pages

A sitemap should not include:

• Draft pages
• Thank-you pages
• Admin URLs
• Noindex pages
• Duplicate URLs
• Search result pages
• Filter URLs that are not meant for indexing

Most CMS platforms and SEO plugins create XML sitemaps automatically. For WordPress, tools like Rank Math, Yoast SEO, or SEOPress can generate sitemaps.

After launch, submit the sitemap inside Google Search Console and Bing Webmaster Tools.

20. Check the Robots.txt File

The robots.txt file tells search engine crawlers which areas of the website they can or cannot crawl. A wrong robots.txt setting can block the full website from Google.

This is one of the most serious launch mistakes.

Before launch, check that important public pages are not blocked.

A basic robots.txt file in WordPress may look like this:

User-agent: *Disallow: /wp-admin/Allow: /wp-admin/admin-ajax.php Sitemap: https://example.com/sitemap_index.xml

Avoid blocking:

• Homepage
• Service pages
• Blog posts
• Product pages
• CSS files
• JavaScript files
• Image folders needed for rendering

Also remove any staging settings such as:

Disallow: /

That line blocks the full website. It is useful for staging sites but dangerous on a live website.

21. Check Heading Hierarchy

Heading hierarchy helps users and search engines understand the structure of a page. Each page needs one clear H1, followed by properly organized H2 and H3 headings.

A clean heading structure looks like this:

• H1: Main page topic
• H2: Major sections
• H3: Subsections under H2
• H4: Extra details under H3 where needed

Avoid these heading mistakes:

• Multiple H1 tags on one page
• Skipping from H2 to H5 without structure
• Using headings only for design
• Using vague headings like “Welcome” or “Our Solution”
• Repeating the same heading across pages
• Hiding important keywords from headings

For SEO, headings should not be forced or over-optimized. They need to clearly describe each section and match the page intent.

22. Add Alt Text to All Images

Alt text describes images for screen readers and search engines. It also appears when an image fails to load.

Every meaningful image needs descriptive alt text. The alt text should explain what the image shows, not randomly repeat keywords.

Good examples:

• “Responsive website design preview on mobile and desktop”
• “SEO audit dashboard showing website performance metrics”
• “Cotton tote bag with custom printed logo”

Bad examples:

• “Image”
• “Photo”
• “Best website best website best website”
• “Untitled-1”

Decorative images do not always need detailed alt text. If an image is only used for design, it can have an empty alt attribute so screen readers skip it.

Example:

<img src=”shape.png” alt=””>

Alt text supports accessibility, image SEO, and better content understanding.

23. Keep URL Structure Clean

Clean URLs help users and search engines understand a page before opening it. A launch-ready website should have short, readable, descriptive URLs.

Good URL examples:

• /website-design-services/
• /seo-services/
• /blog/website-launch-checklist/
• /products/organic-jute-bags/

Poor URL examples:

• /page?id=12345
• /new-page-2/
• /service-final-copy/
• /website_design_services_best_company_final/

A clean URL structure should follow these rules:

• Use lowercase letters
• Use hyphens between words
• Avoid unnecessary numbers
• Avoid dates unless needed
• Avoid random parameters
• Keep URLs short
• Match the page topic
• Do not change URLs repeatedly after launch

URL planning is especially important before launch because changing URLs later requires redirects.

24. Set Up Google Search Console After Launch

Google Search Console helps website owners monitor how Google sees the website. It shows indexing status, search performance, sitemap issues, Core Web Vitals, crawl errors, and manual actions.

After launching the site, verify the domain in Google Search Console.

Important actions:

• Add the website property
• Verify ownership
• Submit XML sitemap
• Inspect homepage URL
• Request indexing for key pages
• Check coverage and indexing status
• Monitor page experience reports
• Review search queries after data appears
• Fix crawl errors

Google Search Console is not optional for SEO. It is one of the most important tools after website launch.

25. Install Google Analytics 4

Google Analytics 4 tracks user behavior after launch. It helps measure traffic, engagement, conversions, source channels, and important events.

Before publishing, install GA4 correctly and test whether the tracking code is firing.

Track important actions such as:

• Contact form submission
• Phone click
• Email click
• WhatsApp click
• Newsletter signup
• Button click
• File download
• Add to cart
• Checkout
• Purchase
• Booking request

Do not only install GA4. Configure useful events and conversions based on the business goal.

For example, a service business may track form submissions and phone clicks. An e-commerce website needs purchase, add-to-cart, and checkout events. A SaaS website may track signups, demo requests, and free trial starts.

26. Add Structured Data or Schema Markup

Structured data helps search engines understand website content more clearly. It uses a format called JSON-LD and supports rich results in search.

Common schema types include:

• Organization schema
• LocalBusiness schema
• Article schema
• BlogPosting schema
• Product schema
• FAQ schema
• Breadcrumb schema
• Review schema
• Service schema
• Website schema

A business website usually needs Organization or LocalBusiness schema. Blog posts need Article or BlogPosting schema. Product pages need Product schema. FAQ sections can use FAQ schema when the content follows Google’s guidelines.

Schema must match visible page content. Do not add fake reviews, fake ratings, wrong business details, or schema that does not represent the page.

A simple schema review before launch helps reduce technical SEO errors and improves search engine understanding.

Performance and Speed Checklist Before Website Launch

Website speed affects user experience, conversion, SEO, and ad performance. A slow website loses visitors before they read the content or fill out a form.

Performance work should happen before launch because heavy images, poor scripts, weak hosting, and unoptimized code become harder to fix after the site is already live.

27. Compress and Optimize Images

Large images are one of the biggest reasons websites become slow. Before launch, every image should be compressed, resized, and served in the right format.

Use modern image formats like WebP where possible. JPEG works well for photos. PNG is useful for transparent images but often creates larger files.

Image optimization checklist:

• Resize images to the actual display size
• Compress large images
• Use WebP format where supported
• Avoid uploading raw camera images
• Add descriptive file names
• Add alt text
• Use lazy loading for below-the-fold images
• Avoid too many large background images

Aim to keep most standard website images under 200KB where possible. Hero images may be larger, but they still need compression.

A 4000px-wide image used in a 600px section wastes bandwidth and slows down the page.

28. Test Page Speed and Core Web Vitals

Core Web Vitals measure real user experience around loading speed, interaction delay, and layout stability. Google uses these signals as part of page experience evaluation.

The three key Core Web Vitals are:

Metric	Meaning	Good Target
LCP	Largest Contentful Paint, main content loading time	Under 2.5 seconds
INP	Interaction to Next Paint, response speed after user action	Under 200ms
CLS	Cumulative Layout Shift, visual stability	Under 0.1

Use tools such as:

• Google PageSpeed Insights
• Lighthouse
• Chrome DevTools
• GTmetrix
• WebPageTest

Test the homepage, main service pages, product pages, blog pages, and landing pages. Do not test only the homepage because inner pages may have different performance problems.

Common speed problems include:

• Large images
• Render-blocking CSS
• Unused JavaScript
• Too many plugins
• Slow server response time
• Heavy page builders
• Poor caching
• Third-party scripts
• Unoptimized fonts

A good website launch process fixes major speed issues before users and search engines visit the site.

29. Enable Caching

Caching stores website resources so pages load faster for repeat visitors. It also reduces server load.

There are different types of caching:

• Browser caching
• Page caching
• Object caching
• Server-side caching
• CDN caching

For WordPress websites, caching plugins or hosting-level caching help improve speed. For custom websites, caching needs to be configured at server or application level.

Caching works best when combined with optimized images, clean code, minified assets, and a good hosting setup.

After enabling caching, test the website carefully. Sometimes caching creates issues with forms, carts, logged-in dashboards, dynamic content, or recently updated pages.

30. Minify CSS and JavaScript

CSS and JavaScript files control design and functionality. Large or unoptimized files slow down page loading.

Minification removes unnecessary spaces, comments, and characters from code files. It makes files smaller and faster to load.

Before launch, check:

• CSS minification
• JavaScript minification
• Unused CSS removal
• Unused JavaScript removal
• Render-blocking resource reduction
• Script loading order
• Critical CSS setup where needed

Be careful with combining JavaScript files because it sometimes breaks sliders, menus, forms, and tracking scripts. Always test the website after optimization.

A clean website does not load unnecessary code on every page. 

For example, a contact form script should not load on every blog post unless needed.

31. Enable Lazy Loading for Images and Videos

Lazy loading means images and videos load only when users scroll near them. This helps improve initial page loading speed.

Lazy loading is useful for:

• Blog images
• Gallery images
• Product images below the first screen
• Embedded videos
• Iframes
• Testimonials with images
• Portfolio sections

Do not lazy load the main hero image if it is the largest visible element above the fold. Lazy loading the hero image may hurt LCP.

Use lazy loading for below-the-fold media.

Example:

<img src=”image.webp” loading=”lazy” alt=”Website launch checklist example”>

Videos also need special attention. Embedding YouTube or Vimeo videos directly can slow the page. Use lightweight video embeds or preview thumbnails where possible.

32. Configure a CDN

A CDN, or Content Delivery Network, stores website assets on servers across different locations. When users visit the site, assets load from a nearby server instead of one far-away origin server.

A CDN improves speed for websites with visitors from different regions or countries.

A CDN helps deliver:

• Images
• CSS files
• JavaScript files
• Fonts
• Videos
• Static assets

Popular CDN providers include Cloudflare, BunnyCDN, AWS CloudFront, and other hosting-based CDN systems.

CDN setup is especially useful for:

• International websites
• E-commerce websites
• Media-heavy websites
• SaaS websites
• Blogs with high traffic
• Business websites targeting multiple locations

After setting up CDN, test SSL, caching, image loading, forms, scripts, and login pages.

33. Enable GZIP or Brotli Compression

GZIP and Brotli compression reduce the size of files sent from the server to the browser. Smaller files load faster and use less bandwidth. Compression is usually enabled at the hosting, CDN, or server level.

Compressible resources include:

• HTML
• CSS
• JavaScript
• JSON
• XML
• SVG

Images and videos are already compressed formats, so they do not benefit from GZIP in the same way.

To check compression, use browser developer tools, online header checkers, or performance testing tools. Look for response headers showing gzip or br.

Compression is a basic performance setting. A launch-ready website should not serve uncompressed text-based assets.

Security and SSL Checklist Before Website Launch

Security checks protect the website, users, business data, and search visibility. A website launch without basic security setup creates risk from the first day. Hackers, bots, spam tools, and automated scanners often target new websites because launch-stage sites commonly have weak passwords, outdated plugins, open test accounts, and incorrect file permissions.

Security work does not need to be complicated at the beginning, but the core setup must be strong before the site goes live.

34. Install SSL Certificate and Use HTTPS

An SSL certificate encrypts data between the user’s browser and the website server. It protects form submissions, login details, payment data, and browsing sessions.

A launch-ready website must load fully on HTTPS. The browser should not show “Not Secure” warnings.

Check these areas:

• Homepage opens with HTTPS
• All internal pages open with HTTPS
• Images load through HTTPS
• CSS and JavaScript files load through HTTPS
• Forms submit through HTTPS
• Payment pages use HTTPS
• Admin login uses HTTPS

Mixed content happens when the main page uses HTTPS but some files still load through HTTP. Mixed content can break icons, images, scripts, fonts, or tracking codes. It also creates browser security warnings.

Before launch, scan the site for mixed content and replace all HTTP asset URLs with HTTPS versions.

35. Redirect HTTP to HTTPS

Installing SSL is not enough. The website must also redirect all HTTP URLs to HTTPS automatically.

For example:

• http://example.com/ should redirect to https://example.com/
• http://example.com/about/ should redirect to https://example.com/about/

Use a 301 redirect for this setup because HTTPS is the permanent preferred version.

Also check the preferred domain version:

• https://example.com/
• https://www.example.com/

Choose one version and redirect the other version to it. This keeps URLs clean and prevents duplicate versions of the same website from being accessible.

36. Update CMS, Themes, and Plugins

Outdated CMS files, themes, and plugins are common security risks. WordPress, Shopify apps, Drupal modules, Joomla extensions, and other CMS tools need regular updates.

Before launch, update:

• CMS core files
• Theme files
• Plugins
• Page builder
• Security plugin
• SEO plugin
• Form plugin
• Payment plugin
• Backup plugin
• Analytics or tracking plugins

Do not update everything blindly on the live site without testing. Run updates on staging first if the website is complex. After updates, test the layout, forms, menu, checkout, login, and tracking scripts.

Remove unused plugins instead of keeping them inactive. Unused plugins add risk and may slow down the site.

37. Set Strong Admin Passwords

Weak admin passwords create one of the easiest entry points for attackers. Before launch, every admin account must use a strong, unique password.

A strong password should include:

• Uppercase letters
• Lowercase letters
• Numbers
• Symbols
• Long character length
• No personal names
• No business name
• No reused password

Enable two-factor authentication for admin accounts where possible. Two-factor authentication adds another security layer even if the password is leaked.

Also avoid common usernames such as:

• admin
• administrator
• test
• demo
• user
• manager

Use role-based access. Not every team member needs full administrator permission.

38. Remove Unnecessary User Accounts

During development, websites often collect test users, developer accounts, demo accounts, temporary admin accounts, and old client accounts. Leaving these accounts active after launch increases security risk.

Before publishing, review all user accounts and remove anything unnecessary.

Remove accounts such as:

• Demo users
• Test admins
• Old developer accounts
• Temporary agency accounts
• Duplicate users
• Default users created by themes
• Inactive staff accounts

For required accounts, assign the correct role. A content editor does not need administrator access. A support user does not need full developer access. Smaller access scope reduces damage if an account is compromised.

39. Sanitize Form Inputs

Forms collect user input. If form fields are not validated and sanitized properly, attackers can inject harmful scripts or database commands.

Form input sanitization helps prevent common threats such as:

• Cross-site scripting
• SQL injection
• Spam injection
• Malicious file uploads
• Fake form submissions
• Broken database entries

Check every form field before launch:

• Name field
• Email field
• Phone field
• Message field
• File upload field
• Search field
• Coupon field
• Login field
• Checkout fields

Use validation rules. For example, an email field should accept a valid email format. A phone field should not accept harmful scripts. A file upload field should allow only safe file types and size limits.

This task is more technical, so a developer should review it before launch.

40. Configure Security Headers

Security headers tell browsers how to handle website content safely. They help reduce risks from clickjacking, content injection, insecure requests, and data leakage.

Important security headers include:

• Content-Security-Policy
• X-Frame-Options
• Strict-Transport-Security
• Referrer-Policy
• X-Content-Type-Options
• Permissions-Policy

These headers are usually added through hosting settings, CDN settings, server configuration, or a security plugin.

Security headers need careful setup because strict settings may break scripts, fonts, embedded videos, payment gateways, or third-party tools. Test the website after adding them.

A good launch process includes both security header configuration and front-end testing.

41. Check File and Directory Permissions

File permissions control who can read, write, or execute files on the server. Incorrect permissions can expose sensitive files or allow unauthorized changes.

Before launch, check that sensitive files and directories are protected.

For WordPress websites, pay attention to:

• wp-config.php
• .htaccess
• Uploads folder
• Plugin folders
• Theme folders
• Backup folders
• Server logs

Avoid world-writable permissions. Do not leave backup files, zip files, database exports, or configuration files publicly accessible.

Examples of risky files left on servers:

• backup.zip
• database.sql
• old-site.zip
• config.php.bak
• staging-copy.zip

These files must be removed or protected before launch.

Functionality and Forms Checklist Before Website Launch

Functionality checks confirm that users can actually complete important actions on the website. A website may look finished, but if forms fail, buttons break, checkout stops, or integrations do not send data, the website is not launch-ready.

Functionality testing should focus on real user journeys, not only visual review.

42. Test All Links and Fix Broken Links

Broken links create poor user experience and waste crawl budget. They also make a website feel unfinished. Before launch, test both internal and external links.

Internal links include:

• Navigation links
• Footer links
• Service page links
• Blog links
• CTA buttons
• Breadcrumb links
• Image links
• Category links
• Product links

External links include:

• Social media links
• Partner website links
• Payment links
• Booking tools
• Google Maps links
• Review platform links
• Third-party resources

Use a link checker tool, Screaming Frog, Ahrefs, Sitebulb, or a CMS broken link plugin. Manual testing is still useful for important CTAs and menu links.

Fix links that return:

• 404 not found
• 403 forbidden
• 500 server error
• Wrong destination
• Redirect chains
• HTTP instead of HTTPS

43. Test All Forms End-to-End

Forms are lead generation points. A contact form that looks fine but does not send messages can silently lose business. Submit every form before launch.

Test these forms if available:

• Contact form
• Quote request form
• Booking form
• Newsletter form
• Login form
• Registration form
• Checkout form
• Demo request form
• File upload form
• Support form
• Career application form

Check the full process:

1. Fill out the form.
2. Submit the form.
3. Confirm success message appears.
4. Confirm email notification arrives.
5. Confirm data is saved in the database or CRM.
6. Confirm the user receives an autoresponder if configured.
7. Confirm spam protection works.
8. Confirm mobile form layout works.

Also test form validation. Empty required fields should show clear messages. Invalid emails should not submit. File upload errors should be easy to understand.

44. Add Form Spam Protection

Public forms attract spam bots. Without spam protection, inboxes and CRMs may fill with fake submissions quickly after launch.

Common spam protection methods include:

• reCAPTCHA
• hCaptcha
• Honeypot fields
• Math challenge
• IP filtering
• Rate limiting
• Email verification
• Form firewall rules

Honeypot fields are often user-friendly because real users do not see them, but bots usually fill them. reCAPTCHA is stronger in some cases, but it can affect user experience if it creates too much friction.

Use stronger protection for forms that receive high spam risk, such as contact forms, quote forms, registration forms, and comment forms.

45. Check Email Notifications

Email notification testing confirms that website messages reach the correct inbox. Many launch problems happen because forms submit successfully but emails go to spam or never arrive.

Test notifications for:

• Contact form submissions
• Quote requests
• Booking confirmations
• Order confirmations
• Password resets
• Account creation emails
• Invoice emails
• Support ticket emails
• Newsletter confirmations

Check sender name, sender email, subject line, reply-to email, message formatting, and deliverability.

Use SMTP instead of default server mail where possible. SMTP improves email delivery and reduces the chance of website emails going to spam.

Also confirm that the business owner, sales team, or support team knows where form submissions will arrive.

46. Test Website Search Functionality

On-site search helps users find pages, products, articles, services, and support information. If search is available, it must return relevant results.

Test common search queries based on user behavior.

For example:

• Service names
• Product names
• Blog topics
• Brand terms
• Category names
• Common misspellings
• Location terms
• Support topics

A weak search system may return no results even when the content exists. For e-commerce websites, poor search hurts product discovery and sales.

Check whether search results show:

• Relevant titles
• Short excerpts
• Product images where needed
• Correct filters
• No private pages
• No draft content
• No duplicate results

If the website does not need search, remove the search box instead of keeping a poor search experience.

47. Test E-Commerce Checkout

For e-commerce websites, checkout testing is one of the most important pre-launch tasks. A small checkout issue can block sales completely.

Test the full purchase journey from product page to order confirmation.

Review:

• Product selection
• Add to cart
• Cart update
• Coupon code
• Shipping calculation
• Billing fields
• Payment method
• Order confirmation
• Customer email
• Admin email
• Inventory update
• Tax calculation
• Thank-you page
• Refund process where needed

Test different scenarios:

• Guest checkout
• Account checkout
• Mobile checkout
• Failed payment
• Successful payment
• Discounted order
• Free shipping order
• Out-of-stock product
• Digital product delivery
• Local pickup if available

Use test payment mode before going live. After launch, make one small real transaction if possible to confirm live payment processing.

48. Make Error Handling User-Friendly

Error messages should help users fix the problem. Vague or technical errors create confusion.

Bad error messages:

• “Error occurred”
• “Invalid input”
• “Something went wrong”
• “403”
• “Submission failed”

Better error messages:

• “Please enter a valid email address.”
• “The phone number field is required.”
• “Your card was declined. Please try another payment method.”
• “The uploaded file must be under 5MB.”
• “Please select a delivery address before continuing.”

Error handling matters for forms, checkout, login, registration, file upload, search, booking, and payment pages.

A good error message should explain what happened and what the user needs to do next.

49. Verify Third-Party Integrations

Modern websites often depend on third-party tools. These tools must be connected and tested before launch.

Common integrations include:

• CRM
• Live chat
• Email marketing platform
• Payment gateway
• Booking system
• Analytics tools
• Ad pixels
• Marketing automation tools
• WhatsApp widget
• Review widgets
• Shipping API
• Inventory system
• Google Maps
• Social media feeds

Do not only check whether the tool appears on the page. Test whether data passes correctly.

For example:

• Does the lead enter the CRM?
• Does the payment gateway process test payments?
• Does live chat send offline messages?
• Does the booking system block unavailable times?
• Does newsletter signup add the user to the right list?
• Does the Meta Pixel track the correct event?
• Does GA4 receive conversion data?

Integration testing protects revenue, tracking accuracy, and customer communication.

Accessibility Checklist Before Website Launch

Accessibility makes the website usable for people with different abilities, devices, and browsing needs. Accessibility is not only a technical requirement. It improves usability for everyone.

A launch-ready website should support keyboard navigation, screen readers, readable text, clear labels, and usable interactive elements.

50. Test Keyboard Navigation

Some users navigate websites using only a keyboard. Keyboard navigation also helps users with motor disabilities and users who cannot use a mouse.

Before launch, test the website using the Tab, Shift + Tab, Enter, Space, and Esc keys.

Check whether users can access:

• Navigation menu
• Dropdown menu
• Buttons
• Links
• Forms
• Search box
• Modal windows
• Sliders
• Accordions
• Checkout fields
• Login fields

A visible focus outline is important. Users need to see which element is currently selected.

Common keyboard issues include:

• Focus gets trapped
• Dropdowns do not open
• Popups cannot be closed
• Buttons are skipped
• Forms are hard to complete
• Focus order is illogical
• Hidden elements receive focus

A website should be usable without a mouse for all important actions.

51. Add ARIA Labels to Interactive Elements

ARIA labels help screen readers understand buttons, icons, and custom interface elements. They are especially useful when a button has only an icon and no visible text.

Examples:

• Search icon
• Close button
• Hamburger menu
• Slider arrows
• Social media icons
• Cart icon
• Account icon
• Filter button
• Video play button

Without ARIA labels, a screen reader may announce a button as only “button,” which does not explain its purpose.

Example:

<button aria-label=”Open navigation menu”>

  ☰

</button>

Use ARIA labels where they improve clarity. Do not overuse ARIA when normal HTML labels already explain the element.

For forms, use proper labels first. ARIA should support accessibility, not replace clean HTML structure.

Post-Launch and Maintenance Checklist After Publishing

Post-launch checks confirm that the live website works properly after publishing. Some issues only appear after the site moves from staging to the live domain. Tracking may fail, redirects may break, pages may not index, forms may stop sending emails, or old URLs may return 404 errors.

A website launch is not finished when the homepage goes live. The first few days after launch are important for SEO, user experience, lead tracking, and technical stability.

52. Set 301 Redirects from Old URLs

301 redirects send users and search engines from an old URL to the new correct URL. This step is critical during website redesigns, domain changes, CMS migrations, URL changes, and content restructuring.

Without redirects, old pages may return 404 errors. That creates a poor user experience and may damage existing SEO value.

Set redirects when:

• Old service page URLs changed
• Blog URLs changed
• Product URLs changed
• Category URLs changed
• Domain name changed
• HTTP moved to HTTPS
• www changed to non-www or the opposite
• Pages were merged
• Pages were deleted and replaced

Example:

Old URL: https://example.com/services/web-design-company/

New URL: https://example.com/website-design-services/

Redirect type: 301 permanent redirect

Before launch, create a redirect map. After launch, test all important old URLs. The best redirect sends users to the closest matching new page, not always to the homepage.

A poor redirect strategy creates soft 404 issues, weak user experience, and lost ranking signals.

53. Monitor Website Uptime

Uptime monitoring checks whether the website is online and reachable. A website may go down because of hosting issues, server errors, plugin conflicts, DNS problems, expired SSL, or traffic spikes.

After launch, set up uptime alerts so the team knows quickly if the website goes offline.

Common uptime monitoring tools include:

• UptimeRobot
• Better Stack
• Pingdom
• StatusCake
• Freshping

Set alerts through email, SMS, Slack, or other team communication channels. For business websites, even a short downtime period may affect leads, sales, ads, and brand trust.

Uptime monitoring is especially important for:

• E-commerce websites
• Lead generation websites
• SaaS websites
• Booking websites
• Campaign landing pages
• High-traffic blogs
• Paid ad landing pages

A launch-ready website needs ongoing monitoring, not one-time testing.

54. Confirm Backup System Is Active

Backups protect the website from data loss, malware, update failure, server crash, human error, and accidental deletion. A website without backups is risky after launch. Set up automatic backups before or immediately after publishing.

A proper backup setup includes:

• Daily automated backups
• Offsite backup storage
• Database backup
• File backup
• Easy restore option
• Backup retention period
• Manual backup before major updates

For small business websites, daily backup is usually enough. For e-commerce, membership, booking, or high-activity websites, more frequent backups may be needed because new orders, users, and form submissions happen throughout the day.

Do not store backups only on the same server. If the server fails, same-server backups may be lost too.

After setting up backups, test the restore process at least once. A backup is only useful when it can be restored properly.

55. Crawl the Website for Broken Links After Launch

A final post-launch crawl helps catch issues that may not appear during staging review. Live URLs, redirects, canonical tags, noindex tags, image paths, and server responses often behave differently after launch.

Use a crawling tool after publishing.

Useful tools include:

• Screaming Frog
• Sitebulb
• Ahrefs Site Audit
• Semrush Site Audit
• Google Search Console

Check for:

• 404 pages
• Redirect chains
• Redirect loops
• Broken images
• Missing title tags
• Duplicate meta titles
• Missing meta descriptions
• Incorrect canonical tags
• Noindex pages
• Blocked pages
• Broken internal links
• HTTP URLs
• Orphan pages
• Large images
• Missing alt text

Run a crawl immediately after launch, then again after a few days. Some errors appear only after search engines, plugins, caches, and users start interacting with the live site.

A clean crawl gives the website a stronger technical foundation.

56. Submit the Website to Google and Bing

Search engines can discover a new website naturally, but direct submission speeds up discovery and gives better control. After launch, submit the sitemap through Google Search Console and Bing Webmaster Tools.

For Google:

1. Open Google Search Console.
2. Select the website property.
3. Go to Sitemaps.
4. Submit the XML sitemap URL.
5. Use URL Inspection for important pages.
6. Request indexing where needed.

For Bing:

1. Open Bing Webmaster Tools.
2. Add and verify the website.
3. Submit the sitemap.
4. Review crawl and indexing reports.

Submit these important pages first:

• Homepage
• Main service pages
• Product category pages
• Product pages
• Blog posts
• Location pages
• Contact page
• About page

Do not request indexing for low-value pages such as thank-you pages, internal search pages, admin pages, duplicate pages, cart pages, checkout pages, or filtered URLs that are not meant for search.

Search submission does not guarantee ranking. It only helps search engines find and process the website faster.

57. Test Social Media Previews

Social media previews control how the website appears when someone shares a page on platforms like Facebook, LinkedIn, X, WhatsApp, Messenger, and other channels.

A broken preview makes shared links look unprofessional. Missing images, wrong titles, cropped thumbnails, or old cached data reduce click-through.

Check Open Graph and Twitter Card tags for important pages.

Review:

• Social title
• Social description
• Featured image
• Image size
• Brand logo
• Page URL
• Preview text
• WhatsApp sharing preview
• LinkedIn preview
• Facebook preview

Recommended Open Graph image size is often 1200 x 630 pixels for standard sharing previews.

Important pages to test:

• Homepage
• Main service pages
• Blog posts
• Product pages
• Campaign landing pages
• Case study pages

Use social preview tools to debug and refresh cached data. Facebook Sharing Debugger and LinkedIn Post Inspector are useful for checking how pages appear when shared.

A strong social preview improves trust and click quality when links are shared in messages, posts, groups, and campaigns.

58. Test Real User Flows

Real user flow testing means watching how people complete important tasks on the live website. This step is also called User Acceptance Testing, or UAT.

Internal teams often miss issues because they already know how the website works. Fresh users notice confusing wording, unclear buttons, broken journeys, mobile problems, and missing information faster.

Ask a few people to complete key tasks such as:

• Find a service page
• Request a quote
• Submit the contact form
• Buy a product
• Book an appointment
• Download a file
• Sign up for a newsletter
• Create an account
• Search for a product
• Read a blog and click a CTA
• Use the website on mobile

Observe where users pause, click the wrong element, miss the CTA, abandon the form, or ask questions.

Good UAT questions include:

• Was the page easy to understand?
• Did the CTA feel clear?
• Was the form too long?
• Did anything feel confusing?
• Did the website load fast enough?
• Did the mobile version feel easy to use?
• Was any important information missing?

Real user testing helps improve conversion after launch. A technically correct website still needs to feel clear for real visitors.

Final Website Launch Review

A complete website launch checklist reduces risk before and after publishing. The main goal is to make sure the website looks correct, works correctly, loads fast, stays secure, supports SEO, tracks user actions, and gives visitors a smooth experience.

Before launch, focus on design, content, SEO setup, performance, security, functionality, and accessibility. After launch, focus on redirects, tracking, indexing, uptime, backups, broken links, social previews, and real user behavior.

A website is not finished after publishing. The launch is the starting point for monitoring, improving, and growing the site based on real data.

How Marketorr Handles Website Launches Before Publishing

Marketorr follows a structured website launch process before making any website live. A website is not published only because the design looks complete. Our team checks the technical setup, SEO foundation, content accuracy, user experience, tracking, and conversion flow before the final launch.

Before publishing a website, Marketorr checks:

• Responsive design: We test the website on mobile, tablet, laptop, and desktop to make sure every page looks clean and works properly.
• Browser compatibility: We review the website on major browsers like Chrome, Safari, Firefox, and Edge.
• Content accuracy: We check spelling, grammar, contact information, CTA text, service details, and placeholder content.
• SEO setup: We review meta titles, meta descriptions, headings, canonical tags, sitemap, robots.txt, image alt text, and URL structure.
• Page speed: We optimize images, caching, scripts, Core Web Vitals, lazy loading, and compression where needed.
• Security setup: We check SSL, HTTPS redirects, admin access, plugin updates, user accounts, and basic security settings.
• Forms and functionality: We test contact forms, quote forms, buttons, links, email notifications, search, checkout, and third-party integrations.
• Tracking setup: We configure and test GA4, Google Search Console, conversion events, pixels, and important user actions.
• Post-launch readiness: We prepare redirects, backup systems, uptime monitoring, indexing steps, and final live-site testing.

Marketorr also checks whether the website supports the real business goal. A lead generation website needs strong CTAs, working forms, conversion tracking, and clear landing page flow. An e-commerce website needs tested product pages, cart, checkout, payment gateway, order emails, and purchase tracking. A corporate website needs strong brand presentation, service pages, trust signals, and a clean technical SEO base.

Marketorr provides website design, web development, SEO, content, tracking setup, and digital marketing support for businesses that want a launch-ready website built for performance. Our focus is simple: No noise. Just results. A website should not only look good when it goes live. It should load fast, work properly, support SEO, capture leads, and create a stronger digital presence from day one.
