Free AEO Scanner
An AEO scanner checks whether AI answer engines like ChatGPT, Perplexity, and Google AI can find, read, and cite your website. Paste your URL and CheckVibe runs 46 AI-visibility checks (crawler access, machine readability, extractability, entity grounding, trust signals) in about 30 seconds.
No source code or signup required to scan, the same pass also covers security and 68 SEO checks.
The silent reasons AI engines skip your site
Being citable is measurable. Princeton's GEO study found that source presentation materially changes visibility in generative engine answers, and Google's AI features documentation ties AI Overviews eligibility to the same crawlability and content fundamentals this scan verifies.

Frequently asked questions
- What is an AEO scanner?
- An AEO (Answer Engine Optimization) scanner checks whether AI answer engines (ChatGPT, Claude, Perplexity, Google AI, Copilot) can find, read, and cite your website. It probes AI crawler access, tests whether your content survives without JavaScript, and verifies the structured data and trust signals engines use to ground their answers.
- What does the CheckVibe AEO scanner check?
- It runs 46 checks across five areas: AI crawler access (robots.txt and WAF rules for GPTBot, ClaudeBot, PerplexityBot, Google-Extended and more), machine readability without JavaScript, content extractability (how liftable your headings, lists, and tables are), entity grounding via schema.org depth and llms.txt, and trust signals like authorship and publish dates, plus a per-engine access matrix for ChatGPT, Claude, Perplexity, Google AI, Copilot, Meta AI, and Mistral.
- What's the difference between AEO and SEO?
- SEO optimizes for ranked links on a search results page; AEO optimizes for being cited inside a composed AI answer. They overlap (crawlability and structured data matter for both) but AEO adds its own failure modes: AI crawlers blocked by robots.txt or a WAF, content that only exists after client-side rendering, and missing grounding signals. CheckVibe runs both scans (68 SEO checks, 46 AEO checks) from one URL.
- Why don't AI engines cite my website?
- The most common causes are silent: your robots.txt or WAF blocks a specific AI crawler, your content only renders client-side so the engine sees an empty page, or there's no schema.org markup and no authorship/date signals for the engine to trust. Nothing looks broken to a human visitor, you just never come up. The scan identifies which of these applies to your site, engine by engine.
- Is the AEO scanner free?
- Yes. Paste your URL and the scan runs free with no install and no signup, you see your issue count and sample findings immediately. A free account unlocks the full breakdown; paid plans add copy-paste AI fix prompts, more scans, and continuous monitoring.
- Does it also check SEO and security?
- Yes, the same scan covers security (exposed API keys, injection, headers, backend config), SEO (68 checks), and AEO (46 checks). One URL, one pass, three reports, so you fix AI visibility and the classic search plumbing together.
