What does seo-audit do?

seo-audit is a Claude skill that audits a website's search health and writes a ranked report. It reads .agents/product-marketing.md if present, then asks about site type, goals, recent changes and Search Console access. It checks in a fixed order: crawling and indexing (robots.txt, sitemaps, canonicals, redirects), speed and Core Web Vitals, mobile, HTTPS and URLs, hreflang for multilingual sites, then titles, meta descriptions, headings, images, internal links and E-E-A-T signals. It warns that curl cannot see JavaScript-injected schema. The report has an executive summary, findings with issue, impact, evidence, fix and priority, and an action plan.

When should you use seo-audit?

Use it when

  • Your organic traffic dropped
  • Pages are stuck on page two of Google
  • You want an audit before a site relaunch

  • You only need schema markup added
  • You want AI search optimization specifically

How the formula works

Is seo-audit safe to install?

Every scanner that checked it passed it. Scanners often miss what other scanners catch, and a skill can change after a scan. Read its source before you install it.
