What we check
Every check the SEO checker runs
One page at a time: the checker reads the HTML search engines see first and reports what is missing, too long or blocking indexing.

On-page SEO and indexability
The SEO scan reviews titles, meta descriptions, heading structure, image alt text, Open Graph tags, and robots or noindex directives on the requested URL.
What it is not
It does not crawl your whole site or pull Search Console data. It is a fast first pass on the page you paste in.
Findings are grouped by severity. A green Passed result is not a warranty that the site is secure or fully optimized. Re-scan after you ship fixes, dependency upgrades, or infrastructure changes.
- CriticalStart here. Affects authentication, transport security, or indexability.
- HighFix in the same pass as critical items.
- MediumUsually a configuration improvement.
- LowSmall hardening or polish, worth batching into a later release.
- InfoDocuments what was observed so you can decide whether it matters for your stack.
- PassedThat check did not find a problem on this pass.
How it works
From URL to report in three steps
Scan flow
01Enter a URL
Paste the page you want to check. No account, credit card or Search Console access.
02Run the SEO check
The checker reads the page's HTML, robots.txt and sitemap, and requests up to 6 of its internal links to catch broken ones.
03Fix and re-check
Work through findings by severity, download the report, and re-check the page after you publish fixes.
Check or audit

Questions about the SEO checker

Yes. It is free to use with no account, credit card or sign-up, and you can check as many pages as you need.
The title and meta description, headings (one H1 and the order of the rest), image alt text, the canonical URL, up to 6 internal links checked for errors, Open Graph and Twitter tags, indexability (noindex, robots.txt and sitemap.xml), structured data, mobile basics such as the viewport and language, and the page's word count.
No. It checks the page you enter. Run it on your key pages one by one, or ask us for a technical SEO audit of the whole site.
No. It reads the public HTML, robots.txt and sitemap, the same files search engines fetch. Rankings, clicks and impressions need Search Console.
The checker flags titles shorter than 30 or longer than 60 characters, and meta descriptions shorter than 70 or longer than 160, the ranges that usually show in full in search results.
Usually a noindex tag, a robots.txt rule that blocks the page, or a canonical URL that points to another page. The report shows which one it found and how to fix it.
Every finding comes with its evidence and the fix. If you would rather hand it over, our technical SEO team fixes it across your templates.
