How the tools work

Each tool runs in your browser where that is possible. The site audit fetches a public page through a public proxy, or reads HTML you paste in. The content optimizer analyses only the text you paste, in your browser, and uploads nothing. Nothing here asks you to create an account, and no tool claims to crawl a whole website or to see private search data.

Tool 1 checks one page at a time. It does not check backlinks or search rankings. Tool 2 checks the text you paste. It does not fetch competitor pages or know Google rankings.

Frequently asked questions

Are these tools really free to use?

Yes. The tools on this site are free to use in your browser. There is no sign-up and no fee listed anywhere on this site.

Do my pages or files get uploaded?

The site audit tries to fetch the public page you enter, through a public proxy, so that page address is sent to that proxy. If you paste HTML instead, that text stays in your browser. The tools do not ask you to upload files to this site.

Why are only two tools live?

The hub is being built one tool at a time, so each tool is finished and tested before the next one starts. The coming-soon pages explain what each next tool will do.

Will these tools replace a paid SEO suite?

No. Paid suites keep very large databases of keywords and links that a free browser tool cannot copy. These tools cover the checks a small site owner needs most often, in plain language.

Which tool should I start with?

Start with the Website SEO Audit. Fix the title, meta description, headings and image alt text it flags, then paste the page text into the Content Optimizer and fix what it flags there.
