Why another SEO checker?
Because most free tools check ten things and charge for the eleventh. This one runs 62 tests across nine categories, shows everything at once and never asks for your e-mail. We built it for ourselves — for the audits we run on every new site anyway — and saw no reason to keep it hidden.
What we check beyond the standard
Classic tools look at title, description, headings and links. We add four areas you rarely find in free checkers: security headers (HSTS, CSP, framing protection), completeness of structured data, correct language versions including x-default, and visibility to AI models — whether your robots.txt blocks GPTBot, ClaudeBot and Perplexity, and whether you have an llms.txt file. That last one is today what a sitemap was ten years ago: nobody demands it, and it already makes a difference.
How it works
You give an address, we fetch the page the way a search engine would, analyse the markup and hand back the result. We store nothing and send no e-mail. The analysis covers a single page — to review a whole site, paste the next address.
Why another tool shows a different score
Because it measures something else. Well-known checkers also count the links pointing to your site — that requires an index of the whole web, which we do not have and do not pretend to have. Our score covers only the technical side of the page itself: code, content, headings, speed, security and structured data. A site without a single external link can therefore score full marks here and still not appear in Google. Treat the two numbers as two different measurements, not two opinions about the same thing.
A score is not an oracle
A hundred points does not mean first place in Google, and seventy is not a disaster. This test measures technique, while rankings also depend on content, links pointing at you and the age of your domain. Treat the result as a to-do list, not a school report.
