Questions about the free tools

Are these tools free?

The browser tools are free to use. Hosted checks show their availability and any shared allowance before you submit; they may be paused.

Do I need to sign up?

Browser tools need no account. Available hosted checks may require a human check and are subject to usage limits.

Can I check any website?

Hosted website checks are intended for public pages and follow crawl restrictions. Browser editors work with what you enter and do not modify your site.

Which AI engines do you check?

ChatGPT, Perplexity, Gemini and Claude through their APIs, and Google AI Overviews from live Google results. All of them run through DataForSEO, a search data provider.

How accurate are the results?

Each result describes what the tool saw when it ran. API answers can differ from what a person sees in the app, and keyword numbers are estimates. Crawl findings don't establish rankings, indexing or AI recommendations, and no tool can guarantee them.

Which tool should I start with?

Start with the technical SEO audit checklist for a client review. For something you can use immediately, try the snippet preview, robots.txt generator or schema markup generator.

What happens after I run a tool?

You get a fix list you can work through yourself. Join the waitlist to explore the early-access workflow for reviewed changes.

Are my results private?

Each result gets its own private link that works for seven days. Only people you give the link to can open it.
