What is AI share of voice?
AI share of voice measures how often your brand appears in AI answers for the prompts that matter to your business, relative to competitors. You run a fixed prompt set across engines several times, count mentions and citations, and express the result as a share. It replaces single rankings because AI answers vary from run to run.
How do you measure AI share of voice?
Pick 20 to 100 real buyer prompts, run each across ChatGPT, Claude, Perplexity, Gemini and Google AI features on a schedule, and record which brands are named and which domains are cited. Track the share per engine and per prompt over weeks. Our weekly client reports are built on exactly this method.
| Input | Why it matters |
|---|---|
| Prompt set | Defines the buying questions you compete on |
| Engines | Each engine retrieves from a different index |
| Repeated runs | Answers vary; one run is a sample of one |
| Competitor list | Share is relative to who else gets named |
Frequently asked questions
What is a good AI share of voice?
It depends on the category and number of competitors. The useful signal is the trend over time against the same prompt set.
Is a mention the same as a citation?
No. A mention names your brand; a citation links to your page as a source. Track both. See AI citation.
