What is an AI visibility score?

An AI visibility score is a single 0–100 number that summarizes how present your brand is in AI-generated answers. It rolls up many individual probes — your buyer questions, put to each AI engine — into one figure you can watch over time. It's the AI-answer equivalent of a domain-authority or rank-tracking number: an imperfect but useful proxy that turns a messy pile of "were you mentioned?" checks into something you can trend and compare.

How a score is typically built

For each of your buyer questions, an engine's answer is checked: were you named, and how prominently. Those per-question results are averaged into a per-engine score (ChatGPT, Claude, Gemini, Perplexity), and the per-engine scores combine into your overall number. A 0 means an engine consistently never named you across the questions asked; a high score means you're reliably in the shortlist.

What a good score looks like

There's no universal benchmark, because it depends on your category and questions. The honest use of the score isn't the absolute number — it's the direction. A score climbing from 20 to 45 over a quarter means your GEO work is landing. A flat 0 means AI has no idea you exist for the questions that matter.

The one caveat

A score is only as honest as its inputs. If an engine couldn't be reached during a scan (a dead API key, an outage), a naive score might show a 0 that means "we couldn't check" rather than "you're genuinely invisible" — which are very different facts. A trustworthy tool distinguishes "not measured" from a real zero, so the number never quietly lies to you.
