Free tool
Free SEO Checker
Enter any URL for an instant technical and on-page snapshot: indexability, canonicals, headings, content depth, alt text and structured data. No signup, no email, no gated report.
Checks one page plus that domain’s robots.txt. Nothing is stored against you.
What it checks
Technical signals
- HTTP status code and full redirect chain
- Canonical tag presence and whether it is self-referencing
- Meta robots and X-Robots-Tag header directives
- robots.txt accessibility and whether the URL is disallowed
- Sitemap declarations found in robots.txt
On-page signals
- Title tag presence and length
- Meta description presence and length
- H1 usage and overall heading structure
- Content word count and depth
- Images missing alt attributes
- Structured data detection
What a tool like this cannot tell you
Automated checks find the mechanical problems: a missing canonical, a noindex nobody meant to ship, a title that got truncated. Those are worth knowing and they are quick to fix.
What no tool can assess is whether your content is genuinely better than whatever outranks you, whether you have the authority to compete for the terms you want, or whether your real problem is that the page converts badly once people arrive. Those need someone to actually look.
So treat the score as a prompt, not a diagnosis. A page scoring 95 can still fail to rank, and a page scoring 60 can rank perfectly well.
Want someone to look properly?
We will review your site and come back with what we would actually tackle first, ranked by what it is likely to be worth.
Questions about the checker
Is this SEO checker really free?
Yes. No signup, no email required and no credit card. Enter a URL and you get the results immediately. We built it because a fast honest snapshot is more useful to most people than a gated report.
What does the tool actually check?
HTTP status and redirect chain, canonical tags, meta robots and X-Robots-Tag headers, robots.txt accessibility and sitemap declarations, title and meta description, heading structure, content depth, image alt attributes and structured data presence.
Does it crawl my whole site?
No. It analyses the single URL you give it, plus that domain robots.txt. That keeps it fast and means it will not put load on your server. For a full site crawl you want a proper audit rather than a snapshot tool.
What does the score mean?
It starts at 100 and deducts for each failed or warning check, weighted by how much that issue typically matters. It is a rough health indicator for the page tested, not a prediction of where you will rank. Treat a low score as a prompt to investigate, not a diagnosis.
Can I use this on a competitor site?
Yes. It only requests pages that are already publicly available, exactly as any browser would. Checking what competitors have got right is a legitimate and useful way to use it.
