Questions

How do I get the HTML of a page?

Open the page, press Ctrl+U (or choose View page source), select everything with Ctrl+A and copy it. On a phone, add “view-source:” before the address in Chrome.

Does a score of 100 mean I will rank first?

No. It means the on-page basics are right. Rankings also depend on useful content, links from other sites, speed and competition.

Is my data private?

Yes. Everything happens inside your own browser: nothing you type or choose is uploaded to us or anyone else.

Is it free?

Completely free, with no sign-up, no watermark and no limit on how many times you use it. Light ads keep the site running.
