What is AI visibility, and how do you measure it?
The metric behind every GEO program, what it leaves out, and how to measure it so the number holds up.
What is AI visibility?
AI visibility is the share of AI answers that mention your brand, across the buyer prompts and AI engines you track. You measure it by asking each engine the same set of prompts on a schedule, counting the answers that name you, and reporting the rate over repeated runs.

Which metrics sit next to AI visibility?
| Metric | What it tells you |
|---|---|
| AI visibility | How often you are named at all. |
| Share of voice | Your mentions out of all brand mentions in answers to questions that name no brand. |
| Average position | Where you appear when you are named; 1 is first. |
| Citations | How often engines cite your pages as a source. |
| Sentiment | How favorably engines describe you. |
Visibility and citations move separately. A brand can be named from third-party reviews without a single citation of its own site, and that matters, because you control your own pages.
Why is one AI answer not a measurement?
Engines give different answers to the same question from run to run, and by model version, location and account. A screenshot shows one draw. A measurement asks the same prompts repeatedly and reports how often you appear, so a change in the number means something changed.
How do you choose the prompts to track?
Use the questions buyers ask before they know your name: category questions, comparisons and problems to solve. Branded prompts (“is Ridgeline good?”) inflate the score. Tag each prompt by journey stage so you can see where you drop out. The free prompt generator builds a starter set.
How does Lighthouse measure it?
Lighthouse types each tracked prompt into the engine’s logged-out page in a real browser, on a schedule, stores every answer with its sources and a screenshot, and counts the answers that name you. Every number opens to the answers behind it. How Lighthouse measures.

Questions people ask
What is a good AI visibility score?
It depends on the category and how many brands compete in the same answers. Compare yourself with the rivals named in your answers rather than with a fixed target, and watch the trend.
How often should you measure?
Weekly is enough to see trends for most brands. Daily runs help when you are testing a change or watching a launch.
