§ 01What the scan checks
What the scan checks
Machine readability
Whether your content survives without JavaScript: server-side rendering, clean HTML and parseable text.
Citation readiness
Liftable facts, stats and definitions a language model can quote with attribution to your domain.
Entity & schema signals
Structured data that tells models who you are, what you sell and how you connect to known entities.
Training-data footprint
Brand presence on the platforms LLMs learn from: Reddit, Wikipedia, YouTube, GitHub, LinkedIn.
Freshness signals
Publish dates and update markers that retrieval-augmented answers rely on when picking sources.
§ 02How it works
How it works
How it runs
We read your robots.txt and llms.txt for the AI agents
If an AI crawler can't fetch your pages, nothing else matters — you simply won't appear in answers. The scan parses your robots.txt to see how GPTBot, ClaudeBot, Google-Extended and PerplexityBot are treated, then checks for an llms.txt manifest and validates its format and coverage. In about 30 seconds you get a clear access map instead of guessing which agents are blocked.
What you act on
Make your site machine-readable on purpose
The free result tells you whether your crawl rules are intentional or accidentally shutting AI agents out, and whether your llms.txt actually points machines to your canonical content. The first scan per URL is free after a Google sign-in — no credit card. Generated llms.txt, robots.txt fixes and the full dashboard come with a paid plan, but the scan alone shows where you stand.
§ 03Why it matters
A visibility scan — not a security scan
“LLM scan” means two different things. Security teams scan LLM applications for vulnerabilities like prompt injection. This is the other kind: a marketing-side LLM visibility scan that checks how language models perceive your website.
When someone asks ChatGPT or Gemini for “the best X”, the model assembles its answer from sites it could crawl, content it could parse and brands it has seen often enough to trust. Every one of those steps is measurable.
The free LLM scan scores all of it across seven dimensions and shows the exact blockers — an AI-blocked robots.txt, JavaScript-only content, missing schema, a thin brand footprint — with prioritized fixes.
