Evidence, not a scoreLive HTML fetch · deterministic checks · no login · no paid AI tokens
Check a webpage
Multiple H1s are not automatically an SEO error; evaluate the page's document structure.
What this check can tell you
The tool reports what it actually observes in fetched HTML. It does not verify JavaScript-rendered changes, indexing, Google rich-result eligibility, ranking impact, or social-platform previews.
Some findings are suggestions for human review, not SEO errors. A failed fetch is reported as a failed fetch — never as a missing tag.
