53% of mobile users abandon a website that takes longer than 3 seconds to load. Google confirmed in 2021 that Core Web Vitals are an official ranking factor. Yet across Bangladesh, thousands of businesses publish high-quality content every week and watch it disappear on page four or five of the search results. The reason is rarely weak content. The website underneath it is technically broken.
A technical SEO checklist is the diagnostic tool that exposes every infrastructure problem standing between your website and a top-three ranking. Technical SEO covers everything Google’s crawlers encounter before they read a single word of your content: how your pages load, whether they can be indexed, how your URLs are structured, and whether your site is secure. Fix these problems first. Content and backlinks built on a broken technical foundation produce unpredictable, short-lived results.
In this article, I will cover every major technical SEO category in precise, actionable steps.
What Is Technical SEO and Why It Is the Foundation of Ranking
Technical SEO is the process of optimizing a website’s infrastructure so search engine crawlers can access, render, understand, and index its pages without obstruction. The goal is to remove every technical barrier between your content and Google’s ranking algorithm.
Search engine optimization operates across three layers. Technical SEO forms the foundation layer. On-page SEO covers your content, headings, and keywords, and builds on top of that foundation. Off-page SEO, which includes backlinks and authority signals, amplifies what the first two layers establish. A site with weak technical infrastructure cannot sustain strong rankings regardless of how many backlinks it earns.
Consider the most direct analogy, a library stocked with thousands of books, but with all doors sealed shut. The books exist. The content is valuable. But no reader, and no search engine crawler, can get inside. Technical SEO opens the doors, lights the shelves, and organizes the books in a logical order so visitors and crawlers alike find exactly what they need in seconds.
Google’s crawler, Googlebot, visits websites at intervals determined by your site’s crawl budget, the quality of your pages, and how frequently your content changes. Googlebot follows links, reads HTML, and sends page data back to Google’s indexing servers. Technical problems such as blocked robots.txt, slow server response, broken redirects, and missing sitemaps interrupt this process at each stage. Interrupted crawling means incomplete indexing. Incomplete indexing means missing rankings.

How to Run Your First Site Crawl with Screaming Frog?
Download Screaming Frog from screamingfrog.co.uk and install it on your desktop. Open the application, enter your domain in the URL bar, and press Start. Screaming Frog crawls your site exactly as Googlebot does, following internal links from page to page and collecting response codes, meta data, heading tags, and canonical URLs for every page it visits.

When the crawl completes, navigate to the Response Codes tab. Filter for 4xx errors (broken pages) and 3xx redirects (redirect chains). Then check the Page Titles and Meta Description tabs for missing or duplicate entries. Export the full crawl data to a spreadsheet to build your audit action list.
Connect Google Search Console to your website by verifying ownership through an HTML tag, Google Analytics, or your domain registrar. After verification, GSC begins collecting real crawl data from Google, including which pages Google indexed, which it skipped, and why. GSC data takes 48 to 72 hours to populate after first setup.
Checklist #1: Crawlability and Indexation
Crawlability is the ability of search engine bots to access your website’s pages. Indexation is the process of Google storing those pages in its search index so they appear in search results. A page that Google cannot crawl cannot be indexed. A page that is not indexed cannot rank. These two factors form the most critical layer of your technical SEO checklist.
Robots.txt Configuration
Priority Level: HIGH
Robots.txt is a plain text file located at yourdomain.com/robots.txt. This file tells search engine crawlers which pages or directories to access and which to skip. A misconfigured robots.txt file is one of the most common causes of complete ranking failure, especially on newly launched WordPress websites where the ‘Discourage search engines’ checkbox was accidentally left enabled during development.

Open Google Search Console, navigate to Settings, and find the robots.txt file in the Crawl Stats section. Alternatively, type your domain followed by /robots.txt directly into a browser. Confirm that your key pages, including the homepage, service pages, blog posts, and product pages, are not blocked by a Disallow rule.
The correct robots.txt for most websites allows all crawlers to access all pages and references the sitemap location:
Recommended Robots.txt Structure
User-agent: *
Allow: /
Sitemap: https://yourdomain.com/sitemap.xml
Block only directories that contain no ranking value: /wp-admin/, /cart/, /checkout/, /login/, /thank-you/, and staging subfolders. Use Google Search Console’s URL Inspection Tool to test any specific URL and confirm Googlebot can access it.
XML Sitemap: Create, Optimize, and Submit
Priority Level: HIGH
An XML sitemap is a file that lists all the URLs on your website you want Google to crawl and index. Google does not require a sitemap, but submitting one accelerates indexing, particularly for new sites, large sites, and sites with pages that have few inbound links.
WordPress websites generate sitemaps automatically through Yoast SEO or Rank Math plugins. The sitemap URL is typically yourdomain.com/sitemap.xml or yourdomain.com/sitemap_index.xml. Submit this URL in Google Search Console under Sitemaps.
A clean sitemap includes only the pages you want indexed. Remove these URL types from your sitemap:
- Pages with a noindex meta tag
- Paginated URLs (page/2/, page/3/) for standard blog archives
- Category and tag archive pages with thin content
- Thank-you pages, login pages, and checkout pages
- Duplicate URLs created by URL parameters
Google imposes a 50,000 URL limit and a 50MB file size limit per sitemap file. Sites with more than 50,000 URLs require a sitemap index file, which is a master file that references multiple individual sitemap files, each under the 50,000 URL threshold.
Google Search Console Index Coverage Audit
Priority Level: HIGH
Google Search Console’s Pages report (formerly Coverage report) shows the indexing status of every URL Google has discovered on your site. Navigate to GSC, click Pages in the left menu, and review four status categories:
| Status | Meaning | Action Required |
| Error | Google found a problem preventing indexing | Fix immediately |
| Valid with Warning | Indexed but has issues worth reviewing | Investigate and fix |
| Valid | Indexed and appearing in search results | Monitor only |
| Not Indexed | Google chose not to index this URL | Review reason and fix if unintended |
The most common Not Indexed reasons on Bangladeshi websites include: ‘Crawled — currently not indexed’ (Google visited the page but deemed it low quality or thin), ‘Discovered — currently not indexed’ (Google knows the URL exists but has not crawled it yet due to crawl budget constraints), and ‘Blocked by robots.txt’ (a robots.txt Disallow rule prevents access).
‘Crawled — currently not indexed’ is the most actionable error. Google’s decision to skip indexing a page signals thin content, low E-E-A-T, or technical quality issues. Improve the content quality on affected pages, increase their internal link count, and request re-indexing through the URL Inspection Tool.
Crawl Budget Management
Priority Level: MEDIUM
Crawl budget is the number of URLs Googlebot crawls on your site within a given time period. Google allocates crawl budget based on your site’s authority and server response speed. Large e-commerce sites with thousands of product pages and filter-generated URLs waste significant crawl budget on low-value duplicate pages, leaving important product and category pages under-crawled.
Google’s John Mueller confirmed that crawl budget waste is a significant problem for sites above 1,000 pages. Fix crawl budget waste by applying noindex tags to faceted navigation pages, using canonical tags on filter-generated URLs, and configuring URL parameter handling in Google Search Console’s Settings.
Noindex and Canonical Tags: Audit and Fix
Priority Level: HIGH
A noindex meta tag placed inside the <head> section of a page tells Google not to include that page in its index. An accidental noindex tag on a revenue-generating page causes that page to disappear from search results entirely. Run Screaming Frog, click the Directives tab, and filter by noindex to find every page on your site carrying this tag. Confirm every result is intentionally excluded.
Canonical tags tell Google which version of a URL is the original, authoritative version. Every indexable page on your site must carry a self-referencing canonical tag. Pages with near-duplicate content, such as product pages with color variants, blog posts syndicated to Medium, and AMP versions of articles, need a canonical pointing to the primary URL. Screaming Frog’s Canonicals tab shows the canonical URL for every crawled page and flags pages missing this tag.
Checklist #2: Website Architecture and URL Structure
Website architecture defines how pages on your site connect to each other through internal links. A well-planned architecture distributes PageRank authority from your most powerful pages down to the pages you want to rank. Poor architecture buries important pages deep in the site hierarchy where Googlebot reaches them infrequently and link equity barely reaches them at all.

Flat Site Architecture: The 3-Click Rule
Priority Level: HIGH
Every important page on your site must be reachable within three clicks from the homepage. Google’s documentation confirms that pages deeper than four or five clicks receive less PageRank and are crawled less frequently. Check click depth in Screaming Frog under Crawl Analysis > Crawl Depth. Any page sitting at depth 5 or greater needs restructuring.
Flat architecture connects the homepage directly to category pages, and category pages directly to individual service, product, or blog pages. Avoid nesting pages inside sub-categories inside categories inside top-level directories unless your site genuinely requires that level of organization (large e-commerce sites with hundreds of categories).
Clean URL Structure
Priority Level: MEDIUM
A clean URL communicates the content of the page to both users and search engines at a glance. Google’s John Mueller stated in a 2021 Google Search Central video that short, descriptive URLs are a minor ranking factor and significantly improve click-through rates in search results.
| URL Type | Example | Assessment |
| Optimal | marketorr.com/technical-seo-checklist/ | Short, keyword-rich, readable |
| Acceptable | marketorr.com/blog/technical-seo-checklist/ | One subfolder, still clean |
| Poor | marketorr.com/?p=1247 | Dynamic, no keyword, no context |
| Poor | marketorr.com/blog/2022/03/15/technical-seo-checklist-for-beginners-updated/ | Too long, date creates maintenance issues |
Use lowercase letters exclusively. Separate words with hyphens, not underscores. Google treats hyphens as word separators and underscores as word joiners. For example, ‘technical-seo’ reads as two words, while ‘technical_seo’ reads as a single word, ‘technicalseo’. Remove dates from URLs for evergreen content to avoid the need to redirect when you update the article.
Internal Linking Strategy
Priority Level: HIGH
Internal links serve two functions: they pass PageRank authority between pages and they guide Googlebot through your site’s content structure. A strong internal linking strategy connects your highest-authority pages, typically the homepage and pillar content pages, to the targeted landing pages you want to rank.
Use descriptive anchor text that tells both users and Google what the destination page covers. Anchors like ‘click here,’ ‘read more,’ and ‘learn more’ waste the ranking signal. Write anchors like ‘technical SEO audit guide,’ ‘Core Web Vitals optimization,’ and ‘SEO services Bangladesh.’
Run Screaming Frog, click the Links tab, and filter by Inlinks with a value of 0. These are orphan pages, meaning pages with no internal links pointing to them. Googlebot reaches orphan pages only through your sitemap, meaning they receive zero PageRank from internal navigation. Add at least two relevant internal links to every orphan page.
Checklist #3: Core Web Vitals and Page Speed Optimization
Core Web Vitals became an official Google ranking factor in May 2021. Google measures three specific performance metrics on real user devices and uses these scores as a ranking signal, a fact confirmed in Google Search Central’s page experience guidelines. 48% of users expect a website to load in 2 seconds or fewer. Each one-second delay in mobile page load time reduces conversion rates by 20%, according to Google’s own data.

Understanding Core Web Vitals in 2026
| Metric | What It Measures | Good Score | Needs Work | Poor Score |
| LCP (Largest Contentful Paint) | How fast the largest visible content element loads | 2.5 seconds or less | 2.5s to 4.0s | More than 4.0s |
| INP (Interaction to Next Paint) | How quickly the page responds to user input | 200ms or less | 200ms to 500ms | More than 500ms |
| CLS (Cumulative Layout Shift) | Visual stability: whether page elements shift during loading | 0.1 or less | 0.1 to 0.25 | More than 0.25 |
2025 UPDATE: INP Replaced FID
Important: Google replaced FID (First Input Delay) with INP (Interaction to Next Paint) as an official Core Web Vital in March 2024. Any checklist or audit tool still reporting FID scores is outdated. INP measures the full input delay, processing time, and presentation delay of all interactions on a page, making it a more comprehensive measure than FID.
How to Improve LCP (Largest Contentful Paint)
Priority Level: HIGH
LCP measures how quickly the largest content element in the viewport, typically a hero image, featured image, or H1 heading, becomes visible. The most common LCP killer on Bangladeshi websites is uncompressed images uploaded directly from cameras or design tools.
- Convert all images to WebP or AVIF format. WebP reduces file size by 25 to 34% compared to JPEG at equivalent visual quality. AVIF achieves up to 50% reduction.
- Add a preload link tag for the hero image in your page’s <head> section: <link rel=’preload’ as=’image’ href=’hero.webp’>. This tells the browser to fetch the hero image as a top priority before parsing the rest of the page.
- Use a Content Delivery Network (CDN) to serve assets from servers geographically close to your visitors. Cloudflare offers a free CDN tier that Bangladeshi sites can activate in minutes.
- Eliminate render-blocking resources. Scripts and stylesheets loaded in the <head> section delay page rendering. Add defer or async attributes to non-critical JavaScript files.
- Optimize your web hosting server response time. Your server’s Time to First Byte (TTFB) directly impacts LCP. A TTFB above 600ms indicates server-side problems. Switch to a faster hosting provider or implement server-side caching.
How to Improve INP (Interaction to Next Paint)
Priority Level: HIGH
INP measures the delay between a user interaction (click, tap, or keyboard press) and the browser’s visual response. Poor INP scores typically indicate JavaScript blocking the browser’s main thread for extended periods.
- Break up long JavaScript tasks. Any JavaScript task exceeding 50ms blocks the main thread and increases INP. Use Chrome DevTools’ Performance panel to identify long tasks and split them using setTimeout() or Web Workers.
- Remove or defer non-critical third-party scripts. Live chat widgets, Facebook Pixel, Google Tag Manager tags, and pop-up scripts all compete for main thread time. Load these scripts after the page’s core content renders using the defer attribute.
- Reduce DOM size. Google recommends keeping your DOM below 1,500 nodes. Excessive WordPress plugins that inject HTML elements into every page inflate DOM size significantly.
How to Improve CLS (Cumulative Layout Shift)
Priority Level: HIGH
CLS measures how much page content shifts position during loading. A layout shift score above 0.1 indicates visible, disruptive shifts: headlines jumping down, text moving mid-read, and buttons shifting away from a user’s tap. Banner ads that load after page content are the number one cause of high CLS on Bangladeshi news and media websites.
- Add explicit width and height attributes to every image and video embed in your HTML. When a browser knows an image’s dimensions before it loads, it reserves that space immediately, preventing a shift when the image appears.
- Reserve space for advertisements, iframes, and dynamic content using CSS aspect-ratio or min-height properties.
- Load web fonts efficiently. Unstyled text shifting to a web font after load contributes to CLS. Use font-display: optional or font-display: swap in your CSS to control this behavior.
Checklist #4: Mobile-First Optimization
Google moved to mobile-first indexing for all websites in July 2024. Mobile-first indexing means Google uses the mobile version of your website, not the desktop version, as the primary source for indexing and ranking. 72% of internet users in Bangladesh access the web exclusively through mobile devices, according to DataReportal’s 2024 Bangladesh Internet Report. A website that performs poorly on mobile is invisible to the majority of Bangladeshi search users.

Core Mobile Optimization Checklist
- Mobile Usability Report in GSC: Navigate to Google Search Console > Experience > Mobile Usability. GSC flags six specific mobile issues: text too small to read, clickable elements too close together, content wider than screen, viewport not set, uses incompatible plugins, and flash usage. Fix every reported issue.
- Responsive Design: Use a single responsive design that adapts to all screen sizes through CSS media queries. Avoid separate mobile subdomain (m.yourdomain.com) setups. Separate subdomains create duplicate content issues and require additional technical maintenance.
- Tap Target Size: Google recommends a minimum tap target size of 48×48 CSS pixels for all interactive elements. Buttons, navigation links, and form fields smaller than this standard cause usability errors in GSC and frustrate mobile users.
- Viewport Meta Tag: Every page must include <meta name=’viewport’ content=’width=device-width, initial-scale=1′> in its <head> section. Missing this tag causes Google to flag the page in the Mobile Usability Report and renders the page at desktop width on mobile screens.
- No Intrusive Interstitials: Pop-ups that cover the main content on mobile pages are a Google penalty risk under the Intrusive Interstitials penalty, active since January 2017. Full-screen ads, large pop-ups, and overlays that require dismissal before content loads violate this guideline.
- Mobile Page Speed Parity: Test your site using Google PageSpeed Insights with the Mobile tab selected. Mobile scores below 50 indicate critical issues. Target a PSI mobile score above 75 for competitive Bangladeshi niches.
Checklist #5: HTTPS, Security, and Site Health
Google confirmed HTTPS as a ranking signal in August 2014. As of 2024, 87.7% of pages loaded in Chrome use HTTPS, according to Google’s Transparency Report. A website running on HTTP displays a ‘Not Secure’ warning in Chrome’s address bar. That warning is a direct trust signal failure that increases bounce rates and reduces form submissions and purchases on Bangladeshi e-commerce and service websites.

HTTPS Implementation Checklist
Priority Level: HIGH
- Confirm your SSL certificate is active and valid. Visit your domain in Chrome. A padlock icon in the address bar confirms HTTPS is active. A ‘Not Secure’ or ‘Your connection is not private’ message indicates an expired or misconfigured certificate.
- Set up automatic SSL certificate renewal. Let’s Encrypt certificates expire every 90 days. Configure auto-renewal through your hosting control panel (cPanel, Plesk) or use Cloudflare’s automatic SSL, which renews without manual intervention.
- Audit for mixed content. Mixed content occurs when an HTTPS page loads assets such as images, scripts, and stylesheets over HTTP. Use Chrome DevTools (Console tab) to identify mixed content warnings. Replace all HTTP asset URLs with HTTPS equivalents or relative URLs.
- Implement a 301 redirect from HTTP to HTTPS and from non-www to www (or www to non-www; pick one canonical domain and redirect all variations to it). Test all four URL variations: http://yourdomain.com, https://yourdomain.com, http://www.yourdomain.com, https://www.yourdomain.com. All four must resolve to the same canonical URL.
Server Errors and Redirect Management
Priority Level: HIGH
5xx server errors (500 Internal Server Error, 503 Service Unavailable) prevent Googlebot from accessing pages entirely. Google Search Console reports 5xx errors in the Pages report under Server errors. A sustained 5xx error on a high-ranking page causes Google to drop that page from search results within weeks.
- Review GSC’s Pages report weekly for any 5xx errors. Contact your hosting provider immediately when 5xx errors appear, as they typically indicate server configuration issues, plugin conflicts (on WordPress), or hosting resource limits being exceeded.
- Audit your 404 errors. Broken internal links that lead to 404 pages waste PageRank and damage user experience. Run Screaming Frog and check the Response Codes tab for 4xx errors. Fix broken internal links by updating them to the correct destination. For deleted pages that had backlinks, implement 301 redirects to the most relevant existing page.
- Eliminate redirect chains. A redirect chain occurs when URL A redirects to URL B, which redirects to URL C. Each hop in a redirect chain reduces the PageRank passed to the final destination. Google’s John Mueller confirmed that redirect chains longer than 3 to 5 hops may cause Googlebot to stop following the chain entirely. Screaming Frog’s Redirects tab shows every redirect chain on your site.
- Use 301 redirects for permanent URL changes. 302 redirects tell Google the move is temporary and do not pass PageRank to the destination URL. Mistakenly using a 302 instead of a 301 on a permanent redirect leaves the original URL indexed and splits link equity between two URLs.
Checklist #6: Duplicate Content and Canonicalization
Duplicate content occurs when the same or substantially similar content appears at multiple URLs. Google does not penalize duplicate content in the traditional sense, but duplicate content forces Google to choose which version to index and rank. Google’s choice is often not the version you intended. The result is split PageRank, inconsistent indexing, and reduced ranking power across all duplicate versions.
Site Version Consolidation
Priority Level: HIGH
Every website exists in at least four versions: http://yourdomain.com, https://yourdomain.com, http://www.yourdomain.com, and https://www.yourdomain.com. Google treats each of these as a separate URL unless you consolidate them through 301 redirects. Set your canonical domain, either www or non-www, and redirect all other versions to it permanently.
Verify consolidation by typing all four variations into a browser and confirming each redirects to your canonical URL with a single 301 (not a chain of redirects). Screaming Frog’s redirect crawl confirms this.
Canonical Tags: Implementation and Audit
Priority Level: HIGH
The canonical tag (<link rel=’canonical’ href=’https://yourdomain.com/page/’>) tells Google which URL is the authoritative version of a page. Self-referencing canonical tags, which point to the same URL they appear on, belong on every indexable page, including pages with no known duplicates. They protect against duplicate content created by URL parameters added by tracking systems, session IDs, and affiliate links.
Faceted Navigation (E-Commerce Sites)
Priority Level: HIGH for e-commerce
Faceted navigation, which covers product filters for color, size, price, and brand, generates thousands of near-duplicate URLs on e-commerce websites. A product category page for ‘Dhaka Electronics Shops’ with 15 filter combinations creates 15 indexed near-duplicate pages, all competing with each other and splitting ranking authority.
Apply noindex meta tags to filter-generated URLs that have no unique ranking value. Use canonical tags on filter pages to point back to the base category page. For filters that do have unique search demand (brand filter pages with significant search volume), allow them to be indexed with unique content.
Checklist #7: Structured Data and Schema Markup
Structured data is code added to a webpage’s HTML that communicates the content’s meaning to search engines in a standardized format. Google uses structured data from Schema.org to generate rich results, which are enhanced search result appearances that include star ratings, FAQ dropdowns, breadcrumb trails, product prices, and event dates. Rich results achieve 20 to 30% higher click-through rates than standard blue-link results, according to data published in multiple Google case studies.

Why Schema Markup Is Non-Negotiable in 2026
In 2026, structured data serves a second critical function beyond rich results: it feeds Google’s AI Overview (formerly Search Generative Experience). Google’s AI systems parse structured data to identify authoritative sources for AI-generated answers. Websites without structured data are at a structural disadvantage in AI-powered search results, regardless of their content quality.
Priority Schema Types to Implement
| Schema Type | Best For | Rich Result Generated |
| Article / BlogPosting | Blog posts, news articles, guides | Article rich result with author and date |
| FAQPage | FAQ sections on any page | Expandable FAQ dropdowns in search results |
| LocalBusiness / Organization | BD local businesses and agencies | Business info panel with address and hours |
| Product | E-commerce product pages | Price, availability, and review stars |
| Service | Service pages (SEO, marketing) | Service details in knowledge panel |
| BreadcrumbList | All pages with navigation hierarchy | Breadcrumb trail shown in search result URL |
| HowTo | Step-by-step instructional content | Step-by-step display in search results |
How to Implement and Validate Schema Markup
Use JSON-LD format for all structured data implementation. Google explicitly recommends JSON-LD over Microdata and RDFa because JSON-LD is separate from the visible HTML content, making it easier to add and maintain. Place JSON-LD scripts inside a <script type=’application/ld+json’> tag in the <head> section of your page.
Validate every schema implementation using two tools: Google’s Rich Results Test (search.google.com/test/rich-results) confirms whether Google can parse your schema and whether your page is eligible for specific rich results. Schema.org’s Markup Validator (validator.schema.org) performs a more comprehensive structural validation against Schema.org specifications.
After implementing schema, monitor Google Search Console under the Enhancements section. GSC lists every structured data type it detects on your site and reports errors, warnings, and valid items. Address errors immediately. Invalid schema receives no rich result treatment.
Checklist #8: Image and Media Optimization
Images account for 21% of average page weight on desktop and 27% on mobile, according to HTTP Archive’s 2024 Web Almanac. Unoptimized images are the leading cause of poor LCP scores and slow first page loads on Bangladeshi websites. Image optimization directly impacts Core Web Vitals, bandwidth consumption, and hosting costs, all of which are critical factors for businesses serving users on slower mobile connections.
| Checklist Item | Priority | Recommended Action |
| Alt text on all images | HIGH | Write descriptive, keyword-relevant alt text for every image. Maximum 125 characters. Do not stuff keywords. |
| Image file format | HIGH | Convert JPEG/PNG to WebP. Use AVIF for highest compression. Both formats are supported in all modern browsers as of 2023. |
| Image compression | HIGH | Use TinyPNG, Squoosh, or ShortPixel before uploading. Target under 100KB for blog images, under 200KB for hero images. |
| Lazy loading | MEDIUM | Add loading=’lazy’ to all images below the fold. Do NOT lazy-load the hero image or any above-the-fold content. |
| Width and height attributes | HIGH | Define explicit pixel dimensions on all <img> tags to prevent CLS layout shifts. |
| Image sitemap | LOW | For image-heavy sites, submit a dedicated image sitemap to GSC to improve image search visibility. |
| Descriptive file names | LOW | Rename files before upload: ‘technical-seo-checklist-2025.webp’ not ‘IMG_00123.jpg’. |
WORDPRESS TIP
WordPress implementation: Install the WebP Express plugin to automatically convert uploaded images to WebP format. Use the Smush or ShortPixel Adaptive Images plugin for automatic compression and lazy loading. Both plugins apply these optimizations without manual intervention on each image upload.
Checklist #9: E-E-A-T Signals and Technical Trust Factors
E-E-A-T stands for Experience, Expertise, Authoritativeness, and Trustworthiness. Google’s Search Quality Rater Guidelines define E-E-A-T as the primary framework human quality raters use to evaluate whether a page delivers value to users. While E-E-A-T is not a direct algorithmic signal with a numerical score, Google’s core ranking systems use related signals including page quality, author credibility, and site trustworthiness that E-E-A-T defines.
Google added the first ‘E’ (Experience) to E-A-T in December 2022, emphasizing that content demonstrating first-hand personal experience with a topic ranks better than content assembled from secondary sources. For YMYL (Your Money or Your Life) topics such as health, finance, and legal advice, E-E-A-T signals carry the highest weight in Google’s quality assessment.
Technical Actions to Strengthen E-E-A-T
- Author schema markup: Implement Person schema for every content author. Include the author’s name, job title, credentials, employer, and links to verified social profiles (LinkedIn, Twitter/X). Google’s systems connect author schema to Knowledge Graph entities, strengthening the author’s perceived credibility.
- About Us page: Publish a comprehensive About Us page that identifies your team members with photos, credentials, and professional history. For Bangladeshi businesses, include your company registration information, physical office address, and years of operation. Link this page from your site’s global navigation.
- Contact page accessibility: A functioning contact page with a verified phone number, email address, and physical location is a baseline trust signal. Google’s quality raters flag websites with no clear contact information as low-quality. Test your contact form monthly to confirm it submits correctly.
- NAP consistency for local BD businesses: NAP stands for Name, Address, Phone number. Your NAP information must be identical across your website, Google Business Profile, Facebook Business Page, and every business directory listing. Even minor variations such as ‘Dhaka-1212’ versus ‘Dhaka 1212’ create inconsistency signals that reduce local search ranking confidence.
- Privacy Policy and Terms of Service: Publish a Privacy Policy and Terms of Service page. Link both from your site’s footer on every page. These pages are mandatory trust signals for YMYL sites and are required under Bangladesh’s Digital Security Act for websites collecting user data.
- Social proof integration: Embed verified customer reviews from Google Business Profile or Trustpilot on your service pages. Use Review schema markup to display star ratings in search results. Review stars in search results increase click-through rates by an average of 17%, according to Trustpilot’s 2023 Ecommerce Report.
Checklist #10: Technical SEO for AI Search and 2025 Future-Proofing
Google’s AI Overview (formerly Search Generative Experience) launched globally in May 2024 and fundamentally changed how users interact with search results. AI Overviews appear at the top of search results for a growing percentage of queries, displaying AI-generated answers that synthesize information from multiple sources. Websites cited as sources in AI Overviews receive significant visibility and referral traffic, but only if their content and technical structure meet the criteria Google’s AI systems use to select sources.

Optimizing for Google AI Overview Citations
Priority Level: HIGH (2026 forward-looking priority)
- Structure content in clear Q&A format. AI systems parse structured question-and-answer content more effectively than dense narrative paragraphs. Use H2 or H3 headings phrased as questions followed by direct, concise answers in the first 40 to 50 words below each heading.
- Implement FAQPage and HowTo schema on all relevant content. Google’s AI systems use structured data to identify authoritative sources faster. Pages with valid FAQPage schema have a higher probability of being cited in AI Overviews for question-based queries.
- Focus on semantic depth over keyword density. Google’s AI systems evaluate topical completeness, not keyword frequency. Cover every subtopic relevant to your main subject. A technically comprehensive page that covers a topic from multiple angles outperforms a keyword-optimized page with shallow coverage.
- Ensure fast TTFB (Time to First Byte). Google’s AI content discovery systems prioritize fast-responding pages. A TTFB under 200ms is the target. Measure TTFB using WebPageTest.org’s Server Response Time metric.
Voice Search Optimization
Priority Level: MEDIUM
- Target conversational, long-tail question keywords that mirror natural spoken language. Voice search queries average 29 words per query, versus 3 to 4 words for typed queries (Backlinko, 2023).
- Achieve a Google PageSpeed Insights score of 90 or above. Backlinko’s 2020 voice search study of 11,000 Google Home results found that the average voice search result page loaded in 4.6 seconds, which was 52% faster than the average web page at that time. Page speed remains a strong voice search ranking factor.
- Implement Speakable schema for content specifically designed to be read aloud by AI assistants. This schema type helps Google Assistant identify which sections of your page contain audio-appropriate content.
Ongoing Technical SEO Monitoring
Technical SEO is not a one-time audit. Google releases hundreds of algorithm updates annually. Each update changes how Google evaluates the technical and quality signals on your site. Build a monthly monitoring routine to catch new issues before they impact rankings.
| Monitoring Task | Frequency | Tool |
| Check GSC Index Coverage for new errors | Weekly | Google Search Console |
| Review Core Web Vitals scores | Monthly | GSC > Core Web Vitals + PageSpeed Insights |
| Crawl site for broken links and redirect chains | Monthly | Screaming Frog |

SET UP AUTOMATIC MONITORING
Pro tip: Set up Google Search Console email alerts under Settings > Email Alerts. GSC notifies you immediately when it detects a significant increase in crawl errors, a manual action penalty, or a security issue. These alerts give you 24 to 48 hours of lead time before ranking impacts appear.

Frequently Asked Questions About Technical SEO
Q: What is the difference between technical SEO and on-page SEO?
Technical SEO optimizes a website’s backend infrastructure: crawlability, indexation, page speed, URL structure, and site security. On-page SEO optimizes the visible content on individual pages: headings, keywords, meta tags, internal links, and content quality. Technical SEO establishes the foundation. On-page SEO builds on top of it. Fixing on-page SEO problems on a technically broken site produces minimal results because Google cannot reliably crawl or index the pages you are optimizing.
Q: How often do I need to run a technical SEO audit?
Run a full technical audit at minimum once per quarter. Additionally, run a targeted audit before and after every major website change: CMS migration, site redesign, new plugin installation, URL restructuring, or hosting provider switch. Set up Google Search Console email alerts to receive immediate notification of critical issues between scheduled audits. Any significant drop in organic traffic warrants an immediate technical audit to identify the cause.
Q: Do I need coding knowledge to implement technical SEO fixes?
No coding knowledge is required for the majority of technical SEO tasks on WordPress websites, which power 43.5% of all websites globally (WordPress.org, 2024). Plugins like Yoast SEO, Rank Math, and W3 Total Cache handle robots.txt configuration, XML sitemap generation, schema markup, and page caching through visual settings panels. Server-level optimizations such as HSTS headers, Gzip compression at the nginx level, and CDN integration require developer involvement but represent a small percentage of total technical SEO tasks.
Q: What are Core Web Vitals and why do they affect my rankings?
Core Web Vitals are three performance metrics Google measures on real user devices: LCP (how fast the largest content element loads, with a target of 2.5 seconds or less), INP (how quickly the page responds to user interactions, with a target of 200ms or less), and CLS (how stable the page layout is during loading, with a target of 0.1 or less). Google confirmed these as ranking factors in May 2021. Pages that pass all three Core Web Vitals thresholds receive a positive ranking signal in Google’s Page Experience system. Pages with poor scores are at a competitive disadvantage, particularly in mobile search where 72% of Bangladeshi users conduct searches.
Q: What is the most important technical SEO fix for a new website?
For a brand new website, the three most critical technical SEO tasks in priority order are: first, confirm Googlebot can crawl your site (check robots.txt is not blocking key pages and submit your XML sitemap to Google Search Console); second, ensure HTTPS is active with a valid SSL certificate and all HTTP URLs redirect to HTTPS; third, run Google’s Mobile-Friendly Test and fix every reported issue before publishing content. Without these three foundations in place, no content strategy or link building campaign produces consistent results.
Q: How long does it take to see results from technical SEO improvements?
Results vary by fix type. Critical crawl error fixes, such as removing an accidental noindex tag from an indexed page or fixing a blocked robots.txt, produce results within 48 to 72 hours once Google re-crawls the affected pages. Structural improvements like site architecture flattening, Core Web Vitals optimization, and internal linking restructuring take 4 to 12 weeks to reflect in rankings, depending on how frequently Googlebot crawls your site and your domain’s existing authority level. Request re-indexing for high-priority pages through GSC’s URL Inspection Tool to accelerate Google’s recrawl.
Q: Is schema markup worth implementing for small businesses in Bangladesh?
LocalBusiness schema is one of the highest-return technical SEO investments available to small Bangladeshi businesses. Correctly implemented LocalBusiness schema displays your business name, address, phone number, opening hours, and star rating directly in Google’s search results and knowledge panel. This enhanced visibility drives phone calls and directions requests without requiring ad spend. FAQPage schema for service pages generates expandable FAQ dropdowns in search results, increasing visual prominence and click-through rate for zero additional content investment.
Conclusion
A technically sound website gives Google every signal it needs to crawl, index, and rank your content effectively. Technical SEO problems do not fix themselves. Each unresolved issue compounds over time. A crawl error left unfixed for six months means six months of missed indexing opportunities for new content published during that period.
Prioritize your fixes in this order: resolve crawl and indexation errors first (robots.txt, sitemap, GSC coverage errors), secure your site with HTTPS next, then address Core Web Vitals and mobile usability, then implement structured data, then tackle duplicate content and URL structure improvements. This sequence addresses the highest-impact issues first and builds each layer on a stable foundation.
