Are AI engines actually finding
your site?
15 weighted checks covering AI crawler access, structured data, content accessibility, and the new llms.txt standard. Get your AI search readiness score in seconds.
What 15 checks reveal
Every signal that determines whether AI search engines can find, parse, and cite your site — weighted by how much it actually matters.
AI crawler access
Are GPTBot, ClaudeBot, PerplexityBot, OAI-SearchBot, ChatGPT-User, and Google-Extended actually allowed in robots.txt — and at the CDN edge?
Structured data (JSON-LD)
Do you have an Organization entity, plus the content schemas (FAQPage, Article, HowTo) AI engines actively cite?
Server-rendered content
AI crawlers don't run JavaScript. We check whether your homepage actually has substantive content in the initial HTML.
Discoverability files
/llms.txt for AI crawlers (Anthropic-endorsed) and a valid /sitemap.xml — both checked and graded.
Edge & CDN behaviour
Detects when Cloudflare or your WAF blocks AI bots invisibly even though robots.txt looks fine. Most tools miss this.
Page basics that matter
Title length, meta description, single H1, complete Open Graph — the same signals that drive AI snippet quality.

Common questions
What is GEO (Generative Engine Optimization)?+
GEO is the practice of structuring your site so AI search engines like ChatGPT, Perplexity, Google AI Overviews, and Claude can find, understand, and cite your content. It builds on traditional SEO but adds new requirements — AI-specific bot access, llms.txt files, and richer structured data.
How does this differ from a normal SEO audit?+
Traditional SEO checks Google rankings. This checks AI visibility. The biggest differences: we test whether OpenAI, Perplexity, and Anthropic's bots can actually reach your site (a Cloudflare default rule blocks them silently on millions of sites), we check for the new /llms.txt standard, and we score the content schemas AI engines actively cite.
Why is the score weighted toward crawler access?+
Because if AI crawlers can't reach your site, nothing else matters. A perfect content marketing site with one Disallow rule for GPTBot scores below 65 — that's the brutal truth of how AI search works in 2026.
Is this really free?+
Yes. 5 scans per day per IP, no signup, no credit card. Your scan generates a public, shareable result page with a unique URL — share it on LinkedIn or send it to your dev team. The full 200+ point audit costs $1 to trial.
How accurate is the score?+
We test what's testable from outside — robots.txt, headers, the rendered HTML, /llms.txt, /sitemap.xml, and how AI bot UAs are treated at your edge. We don't test things requiring authentication or backend access. The score is directional and the per-check evidence is exact.
Will this help me rank in ChatGPT or Perplexity?+
Following the recommendations dramatically improves your odds, but AI citation is also driven by content quality, brand authority, and which sources the LLM was trained on. The full Vantacron audit goes beyond GEO into content quality, link signals, and ongoing AI mention monitoring.
