What Is an AI Visibility Test? Analyze Your Site for ChatGPT, Claude, and Perplexity for Free
See whether your website is discoverable in AI search workflows. Check robots.txt bot access, llms.txt coverage, schema markup, and quotability signals with our free GEO/AEO checker.
People are no longer asking every “where should I buy this?” or “who offers the best service?” question inside Google first. Many of those discovery steps now happen inside ChatGPT, Perplexity, and Claude. Those systems generate answers by citing sources, and most websites still have no idea whether they are even eligible to be cited.
That is the gap our AI Visibility Test was built to expose.
What Is the AI Visibility Test?
The AI Visibility Test is a free GEO/AEO checker that measures how discoverable your site is for AI-assisted search and answer engines.
After you submit a URL, the tool reviews:
- robots.txt bot access for GPTBot, ClaudeBot, PerplexityBot, Google-Extended, and ByteDance Bytespider
- llms.txt coverage so you can see whether an AI-readable content map exists
- Schema markup detection for Organization, FAQ, HowTo, BreadcrumbList, and WebSite
- Quotability signals such as heading structure, meta description quality, E-E-A-T cues, canonical URL setup, and Core Web Vitals heuristics
The checks run server-side in real time. You are not looking at a simulated browser-side mockup.
Chrome Extension Available
You can now run the same AI visibility check directly against the active browser tab. The ilkkod AI Visibility Test Chrome extension makes it easier to review the technical GEO and SEO signals of the page you are already visiting.
It is useful when you want to:
- review important pages on your own site quickly,
- inspect competitor or reference pages without switching tools,
- start with robots.txt, llms.txt, and schema checks before opening the full report flow.
Why These Checks Matter
1. robots.txt: Are AI Bots Allowed In?
Many websites accidentally block AI crawlers with rules like this:
User-agent: GPTBot
Disallow: /
That single rule can stop OpenAI from crawling your content at all, which means ChatGPT has no path to using your pages as a cited source. Our tool checks the five major AI bots separately and classifies each one as Allowed, Blocked, or Unclear.
2. llms.txt: Introduce Your Site to AI Systems
llms.txt is a growing convention recommended by Anthropic and other AI companies. When you place the file at your root, you give AI systems a structured guide to what exists on the site and what matters most. Without it, models have to infer the content map on their own.
3. Schema Markup: Make Context Explicit
JSON-LD schema helps both traditional search engines and AI systems understand your content with less ambiguity. The most valuable types in this workflow are:
- Organization to define who you are,
- FAQPage to expose question-and-answer sections that can be quoted directly,
- BreadcrumbList to make the site structure clearer.
4. Quotability: Is the Page Easy to Cite?
AI systems tend to cite pages with stronger structural signals. We look for items like:
- a clear heading hierarchy (H1 -> H2 -> H3),
- a useful meta description,
- enough passage-level content to extract meaningful snippets,
- E-E-A-T clues such as author name, role, and publication date,
- a valid canonical URL so duplicate versions do not dilute the page.
How the Score Works
The tool generates an AI Visibility Score out of 100.
| Component | Points |
|---|---|
| Each AI bot access check (x5) | 8 points |
| llms.txt present | 10 points |
| Each schema type detected (x5) | 4 points |
| Each quotability signal (x6) | 3 points |
- 70+: Strong, the page is in a good position to be read by AI systems
- 40-69: Mixed, important gaps still need attention
- 0-39: Weak, the page needs immediate cleanup before AI discovery becomes realistic

After you see the score, you can request the full report by email. That report includes:

Final Takeaway
GEO, or Generative Engine Optimization, does not replace SEO. It extends it. If your site should stay discoverable in 2026, it needs to work for both classic search engines and AI-driven answer systems.
Start with the free test, see where the gaps are, and fix the most important ones first.
