The Ultimate Technical SEO Checklist for 2026: 47 Points to Audit

1. Crawlability & Indexation (10 Points)

Start by ensuring Google can find and index your important pages. Check your robots.txt file for accidental disallow rules blocking key pages or directories. Verify your XML sitemap is submitted in Google Search Console and contains only indexable, canonical URLs - no 301 redirected or noindex pages.

Use Google Search Console's Coverage report to identify Crawl Errors (404s, soft 404s, server errors) and resolve them systematically. Check for orphan pages - pages with no internal links - as these are often missed by Googlebot. Use Screaming Frog or Ahrefs Site Audit to crawl your entire site.

Implement proper canonical tags on all pages to prevent duplicate content confusion. Confirm your preferred domain (www vs non-www) is consistent and 301 redirects are in place.

• robots.txt: no accidental disallow on important pages
• XML sitemap submitted in GSC - only indexable, canonical URLs
• Zero crawl errors (404s, 500s, soft 404s) in GSC Coverage report
• No orphan pages - every important page has at least one internal link
• Canonical tags on all pages (self-referencing on unique pages)
• Preferred domain consistent (www vs non-www) with 301 redirect

2. Core Web Vitals (8 Points)

Google's Core Web Vitals are confirmed ranking factors. Your three targets: LCP (Largest Contentful Paint) under 2.5 seconds, CLS (Cumulative Layout Shift) under 0.1, and INP (Interaction to Next Paint) under 200ms.

Measure real-world performance using Google Search Console's Core Web Vitals report and PageSpeed Insights. Pay attention to Field Data (real user data) over Lab Data - Field Data is what Google uses for ranking. For LCP: optimize your hero image with proper sizing, preloading, and next-gen formats (WebP/AVIF).

For CLS: add explicit width/height attributes to all images and avoid inserting content above existing content. For INP: minimize JavaScript execution time, use code splitting, and defer non-critical scripts.

• LCP under 2.5s (Field Data in GSC Core Web Vitals report)
• CLS under 0.1 - add explicit width/height to all images
• INP under 200ms - minimize JS execution, defer non-critical scripts
• Hero image preloaded with fetchpriority="high"
• WebP/AVIF images used site-wide
• TTFB under 200ms - use CDN or server-side caching

3. Site Architecture & Internal Linking (7 Points)

Your site architecture determines how efficiently PageRank flows through your website. Follow the "flat architecture" principle - every important page should be reachable within 3 clicks from the homepage.

Audit your internal link anchor text: use descriptive, keyword-rich anchor text for important deep pages. Check for broken internal links (404s) and fix them. Identify your most-linked internal pages using Screaming Frog's "Inlinks" report and ensure those are your strategically important pages.

Implement breadcrumb navigation on all inner pages - this improves both crawlability and unlocks breadcrumb rich results in SERPs.

• All important pages reachable within 3 clicks from homepage
• No broken internal links (404s)
• Descriptive, keyword-rich anchor text on key internal links
• Breadcrumb navigation on all inner pages with BreadcrumbList schema
• Hub pages (services, categories) link to all sub-pages
• Footer includes links to all primary service pages

4. Page Speed & Performance (8 Points)

Beyond Core Web Vitals, overall page performance affects user experience and rankings. Implement server-side caching (Redis, Varnish, or CDN-level) to reduce TTFB below 200ms. Compress all images to WebP or AVIF format - this single change typically reduces page weight by 30–60% on image-heavy sites.

Minify CSS, JavaScript, and HTML. Remove render-blocking resources by loading non-critical CSS asynchronously and deferring non-critical JavaScript. Use a CDN like Cloudflare to serve static assets from edge locations.

For Indian businesses, choose hosting with data centres in Mumbai or Singapore for lower latency to Indian users. Server response time is especially important for mobile users on 4G connections - which is the majority of Indian internet traffic.

5. Schema Markup & Rich Results (7 Points)

Structured data dramatically improves CTR by enabling rich results. Implement Organization schema on your homepage with your name, URL, logo, social profiles, and contact information.

For service pages: Service schema. For blog posts: Article schema with author, datePublished, and dateModified. For FAQ content: FAQPage schema. For local businesses: LocalBusiness schema with address, hours, and geo-coordinates.

Validate all your schema using Google's Rich Results Test. Most clients see 15–30% CTR improvements from rich result eligibility alone.

• Article schema on all blog posts (author, datePublished, dateModified)
• FAQPage schema on FAQ-content pages
• Organization / LocalBusiness schema on homepage
• Service schema on all service pages
• BreadcrumbList schema on all inner pages
• All schema validated via Google Rich Results Test - zero errors

6. Mobile & User Experience (7 Points)

Google uses mobile-first indexing for all websites - meaning your mobile site is what Google primarily crawls and indexes. Run a Mobile-Friendly Test on all page templates. Ensure all interactive elements have a tap target size of at least 48×48px.

Check that your content is identical on mobile and desktop. Verify font sizes are readable on mobile (minimum 16px for body text). Avoid intrusive interstitials on mobile - these can trigger manual actions from Google.

Test your site on real devices across multiple screen sizes. Mobile users abandon sites with difficult navigation at far higher rates than desktop users.
