Claude SEO: an SEO audit and action plan from one URL

Give it one URL: a 10 to 15 minute audit, up to 17 agents splitting the site, and a ranked list of fixes

After /seo audit, agents spread over the page; a score (41, what one agency's site got) and a ranked action plan come out.

What was hard

Finding out why a site doesn't show up in search meant checking the sitemap, robots.txt, page speed and structured data one by one. Now there is also the question of being cited by ChatGPT or Google's AI Overviews, and tools that hand back a pile of warnings don't say what to fix first.

What it does about it

Claude SEO splits one site among specialist agents. Technical SEO, content, schema, speed and AI search are checked at the same time, the results are gathered into a score, and the fixes are ranked from Critical to Low in an action plan. Each item says why it matters and how you will know it worked.

Is it for you

Good for

  • Owners who want to know why their shop or service site doesn't show up in search
  • SEO agencies and freelancers who check client sites often
  • Checking readiness to be cited by ChatGPT, Perplexity or Google's AI Overviews
  • Handing over an audit as a PDF report

Not for

  • Without Google API keys, Core Web Vitals are lab estimates and indexing is inferred from the page.
  • A full audit runs five judgement-heavy agents on Opus, so it uses more of your Claude plan.
  • Pages that load key content only after scrolling or clicking can give noisy results.
  • The pages analysed are sent to Claude. A private version exists for paying community members.
