AI Visibility Measurement


Short answer

AI visibility measurement establishes how often AI assistants name a company when asked the questions its buyers actually ask. A fixed prompt set is run repeatedly across ChatGPT, Gemini, Perplexity, Claude and Google AI Overviews, every answer is stored verbatim and dated, and the result is a mention rate, a citation rate and a share of voice against named competitors.

Measure first. Everything after a baseline is opinion.

What the engagement covers

Prompt set design
Twenty or more questions drawn from how your buyers actually phrase the problem, not from a keyword tool.
Multi-engine sampling
The same prompts across five answer surfaces, repeated, because a single run is noise.
Verbatim archive
Every answer stored as written, with the date and the engine. A clean before-state cannot be recreated later.
Share of voice
Your mentions as a proportion of all mentions, against competitors you name.

How it runs

  1. Agree the prompt set and the competitor list.
  2. Run the baseline and archive every response.
  3. Report mention rate, citation rate and share of voice.
  4. Re-run monthly. The delta is the report.

Frequently asked


Why not just check ChatGPT myself?

Because a single answer is one sample from a system that varies between runs, sessions and accounts. A rate across repeated runs on five engines is a measurement; one screenshot is an anecdote.

What is a good mention rate?

It depends entirely on the category. In a soft market, being named in eight of twenty prompts is strong. What matters more is the direction of travel from your own baseline.

Do I need this before the optimisation work?

Yes, and it is the one step that cannot be done retrospectively. Once the site changes, the clean before-state is gone permanently.
