Technical SEO Checklist
The complete technical SEO checklist used by Egochi’s award-winning technical SEO team to audit websites for crawlability, indexability, site speed, and search engine accessibility. Use this checklist to identify and fix technical issues that prevent your site from ranking in Google.
What Is Technical SEO?
Technical SEO refers to website optimization that helps search engines crawl, index, and render your pages more effectively. Unlike on-page SEO (content optimization) or off-page SEO (link building), technical SEO focuses on site infrastructure: server configuration, site architecture, page speed, mobile-friendliness, structured data, and crawl efficiency. Egochi’s certified technical SEO services address these backend factors that determine whether search engines can access and understand your content.
Quick Wins: Fix These First
Technical SEO Checklist Categories
Your Progress
1 Crawlability
Ensure search engines can discover and access all important pages on your website.
robots.txt file exists and is properly configured
Check that robots.txt doesn’t block important pages or resources. Access at yoursite.com/robots.txt. Ensure CSS and JavaScript files are not blocked.
XML sitemap submitted to Google Search Console
Create and submit XML sitemap containing all indexable pages. Keep sitemap under 50MB and 50,000 URLs. Update automatically when content changes.
No crawl errors in Google Search Console
Check Coverage report for crawl errors, server errors (5xx), and soft 404s. Fix or redirect problematic URLs promptly.
Internal links use crawlable anchor tags
Links should use standard <a href> tags, not JavaScript onclick events. Googlebot needs standard links to discover pages.
Crawl budget optimized (no infinite spaces)
Eliminate faceted navigation creating infinite URL combinations, calendar pages with endless dates, or parameter-based duplicates wasting crawl budget.
No orphan pages (pages with no internal links)
Every indexable page should have at least one internal link pointing to it. Orphan pages are difficult for search engines to discover.
2 Indexability
Control which pages search engines add to their index and how they handle duplicates.
Important pages are indexable (no accidental noindex)
Check meta robots tags and X-Robots-Tag headers. Staging sites sometimes have noindex tags that transfer to production.
Canonical tags implemented on all pages
Every page should have a self-referencing canonical tag or point to the preferred version. Prevents duplicate content issues from URL parameters, www/non-www, HTTP/HTTPS variations.
No duplicate content issues
Check for duplicate title tags, meta descriptions, and page content. Use canonical tags or 301 redirects to consolidate duplicates.
Thin content pages noindexed or improved
Pages with little valuable content (under 300 words, placeholder pages, tag archives) should be noindexed or consolidated with quality content.
Pagination handled correctly (rel=prev/next or load more)
For paginated content, use canonical to view-all page, implement infinite scroll properly, or let Google handle pagination naturally.
URL parameters handled in Search Console
Configure URL parameter handling to prevent duplicate indexing from tracking parameters, filters, and session IDs.
3 Site Speed & Core Web Vitals
Optimize page load performance to meet Google’s Core Web Vitals thresholds.
Largest Contentful Paint (LCP) under 2.5 seconds
LCP measures loading performance. Optimize largest image/text block. Use preload for hero images, optimize server response time, use CDN.
Interaction to Next Paint (INP) under 200ms
INP measures responsiveness (replaced FID in 2024). Reduce JavaScript execution time, break up long tasks, optimize event handlers.
Cumulative Layout Shift (CLS) under 0.1
CLS measures visual stability. Add width/height to images and embeds, reserve space for ads, avoid inserting content above existing content.
Images optimized and properly sized
Compress images, use next-gen formats (WebP, AVIF), implement responsive images with srcset, lazy load below-fold images.
Browser caching enabled
Set appropriate cache headers for static resources. CSS, JS, and images should cache for at least one week.
CSS and JavaScript minified and combined
Reduce file sizes by minifying code. Combine files where possible to reduce HTTP requests. Defer non-critical JavaScript.
GZIP or Brotli compression enabled
Enable server-side compression for HTML, CSS, and JavaScript. Brotli offers better compression than GZIP.
CDN implemented for static assets
Use Content Delivery Network to serve static files from servers geographically closer to users. Cloudflare, AWS CloudFront, or similar.
4 Mobile Optimization
Ensure your site works well on mobile devices for Google’s mobile-first indexing.
Site uses responsive design
Single URL serves all devices with CSS media queries adjusting layout. Preferred over separate mobile URLs (m.domain.com).
Viewport meta tag configured correctly
Include <meta name=”viewport” content=”width=device-width, initial-scale=1″> in head section of all pages.
No mobile usability errors in Search Console
Check Mobile Usability report for issues like text too small, clickable elements too close together, content wider than screen.
Touch targets adequately sized (48x48px minimum)
Buttons and links should be large enough to tap easily without accidentally hitting adjacent elements.
No intrusive interstitials blocking content
Avoid popups that cover main content on mobile, especially on page load. Google penalizes intrusive interstitials.
Font sizes readable without zooming
Base font size should be at least 16px. Body text should be easily readable on mobile without user zooming.
5 Security & HTTPS
Secure your site with HTTPS and proper security configurations.
Site uses HTTPS on all pages
Every page should load over HTTPS. HTTPS is a confirmed Google ranking factor. Check for mixed content warnings.
SSL certificate valid and not expiring soon
Check certificate expiration date. Set up monitoring for certificate renewal. Use free Let’s Encrypt or paid certificate.
HTTP to HTTPS redirects in place
All HTTP URLs should 301 redirect to HTTPS versions. Include both www and non-www variations.
No mixed content (HTTP resources on HTTPS pages)
All images, scripts, stylesheets, and fonts should load over HTTPS. Mixed content triggers browser warnings.
Security headers implemented
Add headers like X-Content-Type-Options, X-Frame-Options, Content-Security-Policy for additional security.
6 Site Architecture & URLs
Structure your site for optimal crawling and user navigation.
URL structure is clean and descriptive
URLs should be readable, include keywords, use hyphens between words. Avoid long parameter strings, session IDs, unnecessary folders.
Site depth is 3 clicks or fewer from homepage
Important pages should be reachable within 3 clicks. Deep pages get crawled less frequently and may rank lower.
301 redirects for changed URLs (no redirect chains)
Permanently moved pages should 301 redirect to new location. Avoid redirect chains (A→B→C). Update internal links to point directly to final destination.
No broken links (404 errors)
Fix or redirect internal 404 errors. Monitor for new broken links regularly. Update or remove external broken links.
Breadcrumb navigation implemented
Breadcrumbs help users and search engines understand site hierarchy. Implement with Schema.org BreadcrumbList markup.
Consistent internal linking structure
Link to important pages frequently from relevant content. Use descriptive anchor text. Distribute link equity throughout site.
7 Structured Data & Schema
Implement schema markup to help search engines understand your content and enable rich results.
Organization/LocalBusiness schema on homepage
Include business name, logo, contact info, social profiles, and address (for local businesses). Helps Knowledge Panel.
BreadcrumbList schema implemented
Add breadcrumb structured data to help Google understand site hierarchy and display breadcrumbs in search results.
Article/BlogPosting schema on content pages
Include headline, author, datePublished, dateModified, publisher, and image for articles and blog posts.
Product schema on e-commerce pages
Include name, image, description, price, availability, reviews, and SKU for product pages. Enables rich product results.
FAQPage schema on FAQ sections
Mark up FAQ content to potentially display expandable questions in search results. Follow Google’s guidelines strictly.
No schema errors in Rich Results Test
Validate all structured data using Google’s Rich Results Test. Fix errors and warnings before deploying.
8 International SEO
Configure your site for multiple languages or regions (if applicable).
Hreflang tags implemented correctly
If you have multiple language/region versions, use hreflang annotations to specify language and regional targeting for each page.
Hreflang includes x-default for fallback
Include x-default hreflang to specify which page to show users when no specific language/region match exists.
Return links present (bidirectional hreflang)
Hreflang must be reciprocal. If page A links to page B with hreflang, page B must link back to page A.
Country targeting set in Search Console (if needed)
For country-specific subdomains or subdirectories, set geographic targeting in Search Console International Targeting.
9 Monitoring & Ongoing Maintenance
Set up tools and processes to monitor technical health continuously.
Google Search Console set up and verified
Verify all property variations (www, non-www, HTTP, HTTPS) and set preferred domain. Enable email notifications for issues.
Google Analytics 4 tracking installed
Install GA4 for traffic monitoring. Configure conversion tracking. Link with Search Console for keyword data.
Uptime monitoring configured
Use uptime monitoring service to get alerted when site goes down. Check from multiple geographic locations.
Regular crawl audits scheduled
Run technical SEO audits monthly or after major site changes. Use Screaming Frog, Sitebulb, or similar tools.
Backlink profile monitored
Monitor for toxic backlinks, lost links, and new link opportunities. Disavow spammy links if necessary.
SEO performance tracking in place
Track keyword rankings, organic traffic, Core Web Vitals, and conversions. Set up dashboards for regular reporting.

Technical SEO Checklist FAQs
What is a technical SEO checklist?
A technical SEO checklist is a list of website infrastructure items to audit and optimize for search engines. It covers crawlability, indexability, site speed, mobile optimization, security, site architecture, structured data, and international SEO. Egochi’s proprietary checklist includes 50+ audit points used by our certified technical SEO team.
How often should I run a technical SEO audit?
Egochi’s award-winning team recommends monthly technical audits for active websites and immediate audits after major changes (redesigns, migrations, CMS updates). At minimum, run quarterly audits to catch issues before they impact rankings significantly.
What tools do I need for technical SEO?
Essential tools include Google Search Console (free), Screaming Frog (free/paid), PageSpeed Insights (free), and either Semrush or Ahrefs (paid). Egochi’s top-rated technical SEO team uses these plus Sitebulb, GTmetrix, and custom crawling solutions for enterprise sites.
What is the difference between technical SEO and on-page SEO?
Technical SEO focuses on website infrastructure (crawlability, speed, security, architecture) while on-page SEO focuses on content optimization (titles, headings, keywords, internal links). Both are essential for ranking. Egochi’s industry-leading SEO services address both.
What are Core Web Vitals?
Core Web Vitals are Google’s page experience metrics: LCP (Largest Contentful Paint) measures loading, INP (Interaction to Next Paint) measures responsiveness, and CLS (Cumulative Layout Shift) measures visual stability. They became ranking factors in 2021 and were updated in 2024.
How do I fix crawlability issues?
Check robots.txt for accidental blocks, submit XML sitemap, fix internal broken links, ensure JavaScript renders properly, and eliminate infinite URL spaces. Egochi’s certified technical team identifies and fixes crawlability issues as part of every SEO audit.
Why is HTTPS important for SEO?
HTTPS is a confirmed Google ranking factor. Sites without HTTPS show “Not Secure” warnings in browsers, which reduces trust and conversions. Egochi’s proprietary technical SEO includes SSL setup and HTTP-to-HTTPS migration with proper redirects.
What is mobile-first indexing?
Mobile-first indexing means Google primarily uses the mobile version of your site for indexing and ranking. If your mobile site has less content than desktop, that reduced content is what Google sees. Responsive design ensures content parity.
How do I improve site speed?
Compress and properly size images, enable browser caching, minify CSS/JavaScript, use CDN, enable GZIP/Brotli compression, defer non-critical JavaScript, and optimize server response time. Egochi’s award-winning team handles all speed optimization as part of technical SEO services.
What is structured data/schema markup?
Structured data is code (JSON-LD format) that helps search engines understand your content and can enable rich results like star ratings, FAQs, and product info in search results. Egochi’s top-rated team implements schema for Organization, Product, FAQ, Article, and other types.
How do canonical tags prevent duplicate content?
Canonical tags tell search engines which URL is the “master” version when multiple URLs have similar content. This consolidates ranking signals and prevents duplicate content penalties from URL parameters, sorting options, or protocol/subdomain variations.
