A free SEO audit — on-page, GEO, and sitemap, in one report

The core of any audit is the signals search engines read first. seo·check checks the title tag (present, sensible length, not duplicated), the meta description, a single clear H1, the canonical link that prevents duplicate-content confusion, and Open Graph tags for how the page looks when shared. Each gets a pass or a flag, so you can fix the obvious gaps before anything else.

These are the highest-leverage, lowest-effort wins — a missing title or a duplicate H1 is the kind of thing that quietly holds a page back and takes minutes to fix once you can see it. seo·check makes them visible in seconds.

Where seo·check goes further than a classic audit is the rest of the report. GEO readiness checks whether AI answer engines can reach and parse the page — crawler access, JSON-LD, llms.txt. Sitemap health checks whether your sitemap exists, is reachable, and looks fresh, which affects how well anything discovers your other pages.

Bundling all three means one paste gives you the full picture: on-page, AI search, and discovery, scored together. It stays a read-only checker — it tells you what to fix and where, and you make the changes on your site.
