Measures whether AI engines recommend a given website. - **Readiness Score:** Evaluates how parsable and citable a site's structure and content are for AI engines (ChatGPT, Perplexity). - **Visibility check:** Reports whether ChatGPT and Perplexity already mention or cite the site for relevant queries. - **Diagnosis:** Explains specifically why AI does not currently recommend the site, and lists prioritized, actionable fixes. - **No credentials required:** Self-serve, on-demand scan of a public URL, read-only, never modifies the target site. - **Languages:** Available in English, Japanese, and Vietnamese. - **Pricing:** A first Readiness + Visibility scan of your own site is free, no signup required. ## Why teams use it - **AI-readiness score**: One score, broken down by exactly what to improve. - **Is AI recommending you**: See whether ChatGPT and Perplexity already mention you. - **Root-cause diagnosis**: Why AI isn't citing you yet — not just a number. - **Prioritized fixes**: What to fix, ranked by impact — biggest wins first. - **Multi-language, natively**: Scans and reports in English, Japanese and Vietnamese — never machine-translated. - **Recommend-only — safe by design**: Reads only public content. No login, never touches your site. ## Search is splitting, and most sites are invisible on the AI half More buyers now ask ChatGPT or Perplexity before they ever open Google. A site built only for classic SEO can be well-ranked there and still be invisible in AI answers. - You don't know if AI engines mention your site at all → GEO Scanner checks ChatGPT and Perplexity directly and reports what they say about you today. - Classic SEO tools don't check AI-readability → AI-readiness score evaluates the specific structural and content signals AI engines use to parse and cite a page. - "Why doesn't AI recommend us?" has no clear answer → The diagnostic report explains, check by check, exactly what's missing, not just a number. - Fixing everything at once isn't realistic → Recommendations are ranked by expected impact, so you can fix the highest-leverage issue first. - Running a check shouldn't require IT access or a sales call → Self-serve, on-demand scan. Paste a public URL, no login or credentials to your site required. - Most GEO tools only understand English content → Full scans in English, Japanese and Vietnamese — prompt bank, detection and fixes in each market's language, not a translated UI bolted onto an English-only engine. ## How a scan works 1. **Paste your URL**: Enter the page you want to check. No signup required for a first scan. 2. **We scan and check AI engines**: GEO Scanner reads the page's structure and content, and checks ChatGPT and Perplexity for existing mentions. 3. **Get your AI-readiness score and fixes**: A scored report with a prioritized, actionable list of what to fix first. ## Frequently asked questions ### What is GEO? GEO (Generative Engine Optimization) is the practice of making your content easy for AI engines like ChatGPT and Perplexity to parse, understand, and cite. It's the equivalent of SEO for the AI-answer era. ### Is the scan free? The quick preview — checking whether AI can find and read your site, plus a live ChatGPT mention check — is completely free, no signup or card. The full AI-readiness score and the check of whether AI is recommending you (real questions to ChatGPT + Perplexity, root-cause diagnosis, a prioritized fix list) are in the paid plans. ### Which AI engines do you check? Today GEO Scanner checks ChatGPT and Perplexity. We're expanding coverage to more engines as they open up reliable ways to query them. ### Do I need to give you access to my site? No. GEO Scanner only reads the publicly available content of the URL you submit. No login, no credentials, no code to install. The scan is read-only and never modifies your site. ### How is the AI-readiness score calculated? It combines whether AI can find and read your site (crawler access, clear structure, valid structured data) with whether your content actually answers likely buyer questions clearly and early. Every category that falls short is listed in the report with a concrete, easy-to-follow suggestion. ### What languages does GEO Scanner support? The app and reports are available in English, Japanese, and Vietnamese. ### Can I scan a site I don't own? You should only scan sites you own or have a legitimate reason to assess (for example, a client's site you manage). See our Acceptable Use Policy for details. ### Is there a paid plan? Yes. The free scan is a one-time snapshot; paid plans (Starter, Growth, Agency) include a set number of full scans per month, plus extra scans available as credit. Self-serve checkout is on the way — pick a plan via the contact form and we'll set you up manually in the meantime. ## Articles - [What is GEO?
