Is your website visible to ChatGPT?
Your next customers ask AI engines for recommendations — but AI can only recommend sites it can read. This checks the five things that decide whether ChatGPT, Claude, Perplexity, and Google AI can see you, and tells you exactly how to fix what's broken.

The five checks
- 01
AI crawler access — 30 pts — Do GPTBot, ClaudeBot, PerplexityBot, OAI-SearchBot & Google-Extended have permission to read your site — or does robots.txt turn them away at the door?
- 02
llms.txt — 15 pts — The emerging standard for telling AI systems what your site is about, in your own words.
- 03
Structured data — 25 pts — JSON-LD is how machines learn who you are, what you sell, and why to trust you. No schema, no entity.
- 04
Metadata & social tags — 20 pts — Titles, descriptions, Open Graph, canonical, H1 — the basics that both classic SEO and AI extraction depend on.
- 05
Sitemap — 10 pts — The index that guarantees crawlers find every page you care about.
FAQ
What does the AI Visibility Checker test?
Five things AI search engines depend on: whether AI crawlers (GPTBot, ClaudeBot, PerplexityBot, OAI-SearchBot, Google-Extended) are allowed in your robots.txt; whether you publish an llms.txt content map; whether your pages carry structured data (JSON-LD); the quality of your titles, descriptions, Open Graph and canonical tags; and whether a sitemap exists. You get a 0–100 score with a specific fix for every failed check.
Why does AI visibility matter for my business?
A growing share of buying research now happens inside ChatGPT, Perplexity, and Google's AI results instead of classic search. Those engines can only recommend businesses they can crawl, parse, and understand. If your robots.txt blocks GPTBot or your pages have no structured data, you're invisible exactly where your next customers are asking for recommendations.
What is llms.txt?
An emerging standard (llmstxt.org): a markdown file at /llms.txt that gives AI systems a curated map of your site — who you are, what you offer, and which pages matter. It costs nothing to add and ensures AI systems describe your business in your own words.
Is this checker really free?
Yes — the full audit and every fix suggestion, no signup required. If you'd like the fixes implemented for you, that's the kind of work I take on.
