About the seo site checker
This local source audit inspects the supplied document and groups findings by impact. It never fetches or crawls a website and does not promise rankings.
How to use it
- Paste the HTML source or upload the .html file — view-source of any page works.
- Run the audit; the document is inspected locally, never fetched or crawled.
- Read the findings grouped by impact: indexability first, then titles, descriptions, canonicals, headings, images, links.
- Fix in your source and paste again — the loop takes seconds.
Useful for
- Audit a page’s on-page SEO before it goes live, straight from the HTML.
- Check a template change didn’t break titles, canonicals or heading structure.
- Review a client or competitor page from view-source without waiting on a crawler.

SEO Site Checker FAQ
Why paste HTML instead of entering a URL?
Local source auditing means unpublished pages, staging behind a login and work-in-progress templates can all be checked — and nothing you paste leaves your browser. URL-based checkers can only see what is already public.
Will fixing everything it flags improve my rankings?
It removes technical obstacles — pages that can’t be indexed or misdescribe themselves. That is a foundation, not a promise: content and links still decide rankings, and the report never pretends otherwise.
