GEO Technical SEO Audit

Purpose

Technical SEO forms the foundation of both traditional search visibility and AI search citation. A technically broken site cannot be crawled, indexed, or cited by any platform. This skill audits 8 categories of technical health with specific attention to GEO requirements, most critically, server-side rendering (AI crawlers do not execute JavaScript) and AI crawler access (many sites inadvertently block AI crawlers in robots.txt).

How to Use This Skill

1. Collect the target URL (homepage + 2-3 key inner pages)
2. Fetch each page using curl/WebFetch to get raw HTML and HTTP headers
3. Run through each of the 8 audit categories below
4. Score each category using the rubric
5. Generate GEO-TECHNICAL-AUDIT.md with results

1.1 robots.txt Validity

• Fetch https://[domain]/robots.txt
• Check for syntactic validity: proper User-agent, Allow, Disallow directives
• Check for common errors: missing User-agent, wildcards blocking important paths, Disallow: / blocking entire site
• Verify XML sitemap is referenced: Sitemap: https://[domain]/sitemap.xml
