What does the SEO audit check?
225+ site checkups run so far - each one covers on-page SEO (titles, meta descriptions, headings, keywords), site speed, security (HTTPS, SSL, security headers), mobile-friendliness, structured data, social tags, plus a full-site crawl and Google's official Core Web Vitals on mobile and desktop.
What is AI search optimisation (AEO / GEO)?
AI search optimisation, also called answer engine optimisation (AEO) or generative engine optimisation (GEO), is making your website easy for AI assistants like ChatGPT, Gemini, Claude and Perplexity to read, trust and cite, so your brand appears in their answers. Our AI Search Readiness category scores exactly that.
How do I get my website to show up in ChatGPT, Gemini or Claude answers?
Make your content easy to extract: clean server-rendered text, clear headings, structured data (schema.org), an llms.txt file, and pages that answer real questions directly. Run a scan and the AI Search Readiness checks will show you what to work on, and our AI visibility test asks live AI 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 isn't shared. We keep a scan history (the scanned URL, date, scores and check results) so a repeat scan can show your trend over time. If you accept the cookie banner we use Google Analytics to understand overall site traffic - scanned URLs are stripped out before anything reaches Analytics; decline and no analytics cookies are set at all. If you use the email-report option, the address is used once to send your PDF. No lists, no spam.
