A full-site SEO audit is a systematic review of technical access, content quality, structured data, performance, images, and AI-search readiness. Claude SEO runs 8 specialists on every audit and can add 7 conditional specialists, then returns a weighted health score and prioritized fix list. No signup or paid tier is required.
When you run /seo audit, Claude SEO fetches your homepage, detects your business type (SaaS, local service, e-commerce, publisher, or agency), and delegates to up to 15 specialists. Eight run on every audit and seven are conditional on the site type, available integrations, and findings.
The audit crawls up to 500 pages, respects robots.txt, follows redirects (max 3 hops), and uses a 1-second delay between requests to avoid overloading your server. Concurrent requests are capped at 5.
