How to use the Website SEO Checker
The Website SEO Checker is free. Give it a URL, it returns a 0–100 score, a breakdown of what passed and failed, and a ranked list of fixes. No sign-up.
- Paste the page URL in the box above (e.g.
example.com). - Click Check SEO, or press Enter.
- Read the score and grade, then scan the on-page checks for pass, warn or fail.
- Work through Priority fixes top to bottom. They're ordered by impact.
This audit reads the same on-page signals search engines and AI assistants pull from your HTML. It doesn't test page speed or backlinks, so run a speed test alongside it and pair it with an authority check.
