About seo-audit-skill

seo-audit-skill is an open-source set of reusable agent skills for auditing a single web page for SEO. You give an agent a URL, and it produces a structured HTML report with findings. The skills are installed with npx skills add JeffLi1993/seo-audit-skill and are described as working with Claude Code, Cursor, and any agent runtime that supports SKILL.md.

The tool uses two layers. Python scripts run deterministic checks such as HTTP status, XML parsing, and string matching. The language model handles judgment-based review, such as keyword intent, content quality, and page type. The basic skill, seo-audit, covers a set of site-level and page-level checks. The full skill, seo-audit-full, adds PageSpeed, sitemap inventory, Search Console crawl status, and additional checks. Full audits need a Google PageSpeed Insights API key, and without one the full audit stops and asks for a key.

Key features

  • Single-page basic audit from a URL, saved as a standalone HTML report
  • Full audit adds Lighthouse PageSpeed scores and lab metrics
  • Checks robots.txt, sitemap.xml, 404 handling, and URL canonicalization
  • Checks hreflang, JSON-LD schema, and E-E-A-T trust pages
  • Page checks cover title tag, meta description, headings, and internal links
  • Priority actions list the top three fixes, with evidence, impact, and fix for each finding
Best for: Developers and SEO practitioners who use AI coding agents such as Claude Code or Cursor and want per-page audit reports.
Good for
  • Open source, with the code available in a public GitHub repository
  • Separates deterministic script checks from language-model judgment
  • The basic audit tier does not list an API key requirement, while the full tier does
Watch out for
  • The full audit requires a Google PageSpeed Insights API key and stops without one
  • PageSpeed, Search Console crawl status, and sitemap inventory are full-audit only
  • The source advises reviewing the report and keeping only the findings that match your goals
