A technical SEO audit checks whether search engines and AI systems can access, crawl, index, and understand your website. It is the most foundational audit type because technical problems prevent every other optimization from working at full capacity.

The Five Technical Audit Categories
Crawl Access Check robots.txt for any Disallow rules blocking important pages. Check specifically whether AI crawlers including GPTBot, ClaudeBot, PerplexityBot, and Google-Extended are allowed. Use aiagentchecker.net for the AI-specific check. A blocked AI crawler means complete invisibility to that AI system regardless of content quality.
Verify your XML sitemap is valid and submitted to Google Search Console. Every page you want indexed must be included. Check for sitemap errors in the Coverage report.
Indexation Verify canonical tags are correctly implemented on all pages. Canonical errors split ranking authority across URL variants. Check that no important pages have accidental noindex tags. Verify HTTP to HTTPS redirects are configured on all URLs.
Performance Check Core Web Vitals on mobile specifically via the All In One SEO Audit. LCP must be under 2.5 seconds. INP must be under 200 milliseconds. CLS must be under 0.1. Google uses these as direct ranking factors. Failing scores penalize every page simultaneously.
Architecture Check for redirect chains where Page A redirects to Page B which redirects to Page C. Each hop loses link equity. Identify broken redirects returning 404 errors. Check internal link depth ensuring important pages are reachable within three clicks from the homepage.
Schema Verify Organization schema on the homepage, LocalBusiness schema on location pages, FAQPage schema on Q&A content. Check schema validity at allinoneseoaudit.com/schema-markup. Invalid schema is invisible to Google.
