AI visibility is measured by running a fixed panel of buying-intent prompts against each assistant on a schedule and recording whether you appear, how you are described and who appears instead. There is no impression count, no rank position and no equivalent of Search Console — anyone showing you one has built it from sampling, same as us.
The measurement problem starts with non-determinism. Ask the same assistant the same question twice and you can get two different vendor lists, so a single check tells you nothing. We build a panel of 50 to 200 prompts drawn from how your buyers actually phrase things — category questions, comparison questions, problem-symptom questions, and direct brand questions — then run them repeatedly across ChatGPT, Perplexity, Claude, Copilot, Gemini and AI Overviews, and report distributions rather than snapshots.
From that you get four honest numbers: presence rate (in what share of runs are you mentioned), share of voice against named competitors, sentiment and accuracy of how you are described, and citation source mix (which URLs the model pulled, yours or someone else's). We pair that with server-side evidence — AI crawler hits in your logs, segmented by bot, showing what is being fetched and what is returning 4xx — and with referral and assisted-conversion data from chatgpt.com, perplexity.ai and copilot in GA4.
Now the honest part. Referral data understates reality badly, because most AI answers resolve the user's question without a click; a mention that shapes a shortlist leaves no analytics trace at all. Model updates can move results overnight for reasons no vendor controls. And nobody can attribute a closed deal to a citation with any rigour. The most reliable secondary signal we have found is branded search volume and direct traffic lift, which tends to move a few weeks after presence rate does. We report all of this as it is, including the months where it does not move.
- Fixed prompt panel, run on schedule across every major assistant, reported as distributions across repeated runs
- Presence rate, competitive share of voice, description accuracy and citation source mix as the four core metrics
- Server log analysis segmented by AI crawler — what they fetch, how often, and what errors they hit
- GA4 referral and assisted-conversion tracking for AI sources, with its limitations stated rather than hidden
- Branded search and direct traffic as the lagging proxy for zero-click influence
- No guaranteed citations, no invented ranking positions, no metric we cannot show you the collection method for
