One command. 9 AI agents analyze your website in parallel - technical SEO, content quality, schema markup, AI search readiness, performance, and images. You get a 0-100 health score and a prioritized action plan. The kind of analysis agencies charge $5-10K/month to produce.
When you run /seo audit, Claude SEO fetches your homepage, detects your business type (SaaS, local service, e-commerce, publisher, or agency), and then spawns up to 9 specialized AI agents that run simultaneously. Each agent focuses on a different dimension of SEO analysis.
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.
What Each Agent Analyzes
The 9 agents cover every dimension of modern SEO. Seven run on every audit. Two additional agents (Local SEO and Maps) spawn conditionally when the system detects a local business.

QUESTIONS ABOUT THE AUDIT
A full site audit typically completes in 2-3 minutes. 9 AI agents run in parallel, each analyzing a different aspect of your site simultaneously. Sites with more than 100 pages may take slightly longer due to crawl depth.
The score is a weighted aggregate across 7 categories: Content Quality (23%), Technical SEO (22%), On-Page SEO (20%), Schema/Structured Data (10%), Performance including Core Web Vitals with INP (10%), AI Search Readiness (10%), and Images (5%). Each category produces its own sub-score.
Claude SEO auto-detects 5 business types from homepage signals: SaaS (pricing pages, feature lists, documentation), Local Service (phone numbers, addresses, service areas), E-commerce (product pages, shopping carts), Publisher (blogs, articles, author pages), and Agency (case studies, portfolios, client logos). Recommendations adapt to the detected type.
The audit crawls up to 500 pages per site. It respects robots.txt, follows redirects (max 3 hops), and uses a 1-second delay between requests to avoid overloading servers. Concurrent requests are capped at 5.
