Frequently asked questions

  • Is this SEO checker really free?

    Yes, completely free, no sign-up, no credit card, no trial limits. Paste any website URL and you get the full report: keyword insights, Core Web Vitals and a downloadable PDF. 340+ site checkups have been run here so far.

  • What does the SEO audit check?

    340+ site checkups have run here so far. Each one covers on-page SEO: titles, meta descriptions, headings and keywords. It also covers site speed, security, how the page behaves on a phone, structured data and social tags. Then it crawls the rest of your site and pulls Google's own Core Web Vitals for mobile and desktop.

  • What is AI search optimisation (AEO / GEO)?

    AI search optimisation means making your site easy for an AI assistant to read, trust and quote. Do that and your brand turns up in the answers ChatGPT, Gemini, Claude and Perplexity give. The same thing goes by two other names: answer engine optimisation (AEO) and generative engine optimisation (GEO). Our AI Search Readiness category scores it.

  • How do I get my website to show up in ChatGPT, Gemini or Claude answers?

    Make your content easy to lift. That means text the server sends as text, clear headings, structured data, and pages that answer a real question in the first paragraph. An llms.txt file costs nothing to add, though no major AI company has said it reads one. Run a scan. The AI Search Readiness checks show you what to fix. The AI visibility test goes further and asks the engines whether they already mention you.

  • Why is my speed score different from Google PageSpeed Insights?

    The report's Speed category is an instant estimate computed from your page itself. The Core Web Vitals section is Google's official Lighthouse data, from the same engine as PageSpeed Insights, on both mobile and desktop. Lab scores also naturally vary a few points between runs.

  • Do you store my website data or my email?

    No account is needed and your report is not shared. We keep a scan history: the URL, the date, the scores and the check results. That is what lets a repeat scan show your trend. Accept the cookie banner and we use Google Analytics to see overall traffic, with scanned URLs stripped out before anything reaches it. Decline and no analytics cookies are set at all. If you email yourself a report, the address is used once to send the PDF. No lists, no spam.
