FAQ
Do you fetch my URL?
No. Fetching a URL from our site would send the page through a server. Paste View Source HTML instead. That is why the checker can stay private.
Do I need an account?
No. Open the page and paste HTML.
What does the score measure?
On-page signals: title, description, H1, headings, canonical, viewport, Open Graph, image alts, JSON-LD, and whether the page is indexable. It does not measure backlinks or rankings.
