Free AI visibility checker.
See whether ChatGPT, Claude, Perplexity, and Gemini can find, understand, and cite your brand.
Invisible at the exact moment a buyer is deciding.
One free scan checks bot access, structured data, llms.txt, and content signals, then returns a single 0-100 AI visibility score with a prioritized fix list. It runs on our AI Readiness Score engine.
Why AI visibility matters
AI search engines increasingly answer questions that used to start on Google. When someone asks ChatGPT, Claude, Perplexity, or Gemini about your category, those engines pull from sources they can crawl, parse, and trust. They name a short list of brands in the answer. If they cannot access or understand your site, you are invisible at the exact moment a buyer is deciding.
Traditional SEO checks how you rank. An AI visibility checker checks something different: whether AI systems can find your content, recognize your brand as an entity, and cite you in their answers. This free checker measures the technical signals that determine that outcome.
What the checker measures.
5 checks, each with a plain-English reason it matters. Every one maps to a line in the report.
Bot Discoverability
Can OpenAI, Claude, and Perplexity retrieval agents and search engines reach your pages? Checks robots.txt, meta robots, and header rules across 17 crawlers, with training policies assessed separately.
Structured Data
JSON-LD coverage and quality: Organization, Article, and the other schema types that declare your brand and pages.
LLM Communication
llms.txt presence, structure, entity definitions, and use policy. It counts toward this score but is optional: Google says Google Search ignores it.
Content Accessibility
Server-side rendering, title and description quality, and whether your content is readable without JavaScript execution.
Cross-Signal Readiness
How well your signals agree: structured data, llms.txt, bot access, and SSR working together instead of contradicting each other.
How the score works explained.
The checker runs our AI Readiness Score engine, which synthesizes five weighted categories into one 0-100 score and an A-F grade. Run the full tool for the complete category breakdown.
