⚠️ What this checks: on-page HTML signals only (title, meta, headings, mobile viewport, HTTPS, canonical, Open Graph, structured data, alt text, content length). It does not measure page speed, Core Web Vitals or backlinks.
How to use the Website SEO Checker
The Website SEO Checker is a free tool that audits any page's on-page SEO and returns an instant 0–100 score with a clear breakdown and a prioritized list of fixes — no sign-up required.
- Paste the page URL you want to audit into the box above (e.g.
example.com). - Click Check SEO (or press Enter).
- Read your score and grade, then scan the on-page checks for pass / warn / fail.
- Work through the Priority fixes from top to bottom — they're ordered by impact.
This audit looks at the signals search engines and AI assistants read in your HTML. It checks on-page structure, not page speed or backlinks, so pair it with a speed test and an authority check for the full picture.
