Runs a set of on-page checks on the live HTML of a public URL: title, meta description, canonical, headings structure, robots instructions, robots.txt, sitemap.xml, Open Graph, X/Twitter cards, images, HTTPS, viewport, language, links and structured data. Each check is explained so you know what it means and why it matters.
What this tool does
The checker retrieves a live copy of the page — directly from the browser if the site allows cross-origin access, otherwise through a clearly labeled public relay — and parses the real HTML in your browser. Every check you see is computed from that HTML, and the source of the HTML is shown on the result.
robots.txt and sitemap.xml are fetched separately from the same origin.
What it does not do
- It does not produce an official Google SEO score (only Google knows how it ranks pages).
- It does not evaluate backlinks, domain authority or content quality in ranking terms.
- It does not invent checks when the page cannot be retrieved — it tells you the page was unreachable.
Limitations & transparency
Some target sites block the public relays this tool uses (allorigins.win, cors.lol, cors.eu.org) or are temporarily unavailable. When no copy of the page can be fetched, the tool reports exactly that instead of pretending to check. Note also that “Passed” here means the on-page element is present and sensible — it is not a guarantee of search rankings.
The submitted URL is transmitted to the retrieval endpoints used for that page and to none other. Nothing is stored by this site. See the Privacy Policy.
FAQ
Why does everything show “Needs attention” even though my site ranks fine?
This tool only reports on-page facts. A site can rank well despite missing meta tags, and a technically clean site can rank poorly. Think of the checks as a hygiene checklist, not a ranking predictor.
Why is robots.txt or sitemap.xml sometimes "Not retrievable"?
Some servers block the public relay services used to fetch remote files. The file may be perfectly reachable from your own network. Check it in a browser tab: yoursite.com/robots.txt.
Is a missing canonical a big problem?
Only if the same content is reachable at multiple URLs (e.g. www vs non-www, or tracking parameters). If every version of the page is unique, it is less important.
Does "Passed" mean Google will rank me higher?
No. Passing hygiene checks removes common obstacles, but rankings depend on content quality, relevance, authority and competition — none of which this tool measures.
