About this Skill
Reads a folder of your site's HTML and checks every page for the one-shot SEO basics — title, meta description, headings, image alt, canonical, Open Graph, language, viewport, and broken internal links — then scores each page 0-100 and returns a fix list sorted by impact x effort, highest value first. No network access: external links are counted, never fetched, so the audit is fast, private, and reproducible on any static export.
Try it

FAQ
Does it check external links?
No. External links are counted, never fetched — this skill audits only what it can verify locally, so a broken external link is never reported on a guess.
Will fixing everything improve my rankings?
It removes the on-page basics that hold a site back, but rankings also depend on content, links, and competition. The report states scores and issue counts; it never promises traffic.
