About JustYourSEO

What JustYourSEO is

JustYourSEO is a set of 26 free SEO tools, from a SERP preview and meta tag generator to schema markup generators, a keyword density checker and a robots.txt tester, plus 7 reference pages such as a meta tags cheat sheet and a list of AI crawler user agents. Every tool runs in your browser and needs no sign-up. More tools are on the way.

How it's funded

Pages show a small number of clearly labeled ads. That's how every tool stays free, with no sign-up and no limits.

Your text and HTML

Titles, descriptions, URLs, page source, robots.txt files, sitemaps and images you use in the tools are processed by JavaScript in your browser. They aren't sent to our server, stored or logged, and they're gone when you close or reload the page. The tools work on what you type or paste; they don't fetch pages from the web. Pages are measured with Google Analytics and ads come from advertising partners; neither receives what you enter into a tool. See the privacy policy for details.

Built on open source

Most of the tools are small, purpose-written code that runs in your browser: pixel widths are measured with the browser's own text rendering, and robots.txt matching follows RFC 9309. Where a well-tested library does the job better, we use it. Thank you to its authors:

• fast-xml-parser (MIT): Reading and checking XML sitemaps

Accuracy

Tool and reference pages follow primary sources: Google Search Central documentation, RFC 9309 for robots.txt, the sitemaps.org protocol, schema.org and the crawler operators' own published documentation. Search engines change their behavior and layouts, and previews of pixel widths are approximations, so treat results as guidance rather than guarantees. No tool can promise rankings.
