Frequently asked questions

Are these SEO tools free and private?

Yes. Every tool is free with no sign-up and runs in your browser. Your content stays on your device and is never uploaded, and they work offline once loaded.

Do I need to install anything?

No. They work in any modern browser on phone, tablet or computer, with no download, plugin or account.

Which tools are included?

A meta and Open Graph tag generator, a social card preview, a keyword density checker, a robots.txt generator and a sitemap.xml generator.

Will these help my search ranking?

They help you get the technical basics right, such as well-formed meta tags, clean robots rules and a valid sitemap, which support good SEO. Rankings also depend on content quality, links and many other factors.

Can they crawl my website automatically?

No. A browser cannot crawl other sites for security reasons, so for the sitemap you paste your URLs and for previews you enter the details. Everything is then generated locally.
