What is an AI visibility tool?

The short answer

An AI visibility tool checks two things. First, whether AI assistants can read your website at all. Second, whether they actually mention you when someone asks a question in your category.

If the answer to the first is no, nothing else matters. Many sites quietly block the crawlers that feed these assistants, usually by accident.

How it is different from an SEO tool

An SEO tool tracks your place in a list of links. Being tenth still gets you a link on the page. An AI assistant writes one answer. You are either in that answer or you are invisible. There is no tenth place.

That is why the measurement is different. Instead of a rank number, you get a mention: named first, named later, or not named at all.

What a good tool measures

• Crawler access. Whether GPTBot, ClaudeBot and PerplexityBot are allowed to read your pages.
• Machine-readable facts. Whether your titles, headings and structured data say clearly what you do and where.
• Answer-ready writing. Whether your pages contain sentences an assistant can quote directly.
• Real mentions. Whether you are named when the assistant is asked the questions your buyers ask.
• Competitors. Who is named instead of you, and how often.
• Change over time. Whether the work you did moved anything.
