Open toolWhat these seo tools cover
The parts of SEO that are pure markup, not guesswork. Build a robots.txt or an XML sitemap, generate JSON-LD schema you can paste into a page, write hreflang tags for a multilingual site, check keyword density in a draft, or audit the alt text on a list of image tags. These tools do not sell traffic estimates or difficulty scores, because those numbers come from paid datasets and inventing them would be worse than leaving them out.
Common jobs
- Writing a robots.txt that does not accidentally block CSS
- Generating a sitemap for a static site
- Adding FAQ or breadcrumb schema without hand-writing JSON
Why they run on your device
These pages are static files. The work is done by JavaScript in your tab, so a file or a password never leaves your machine — there is no upload endpoint on this site to send it to. That also means no account, no usage counter and no queue.
Questions
Why is there no keyword volume tool?
Volume and difficulty come from paid datasets with licences that forbid redistribution. Any free site showing those numbers is either paying for an API or making them up.
Is generated schema valid?
It follows the schema.org vocabulary for the type you pick. Paste it into Google's Rich Results Test to confirm before publishing.
