AI Share of Voice · five assistants, 40+ prompts

How much of the category conversation is yours?

Share of voice is the percentage of category answers that name you rather than a rival. It is the closest thing this channel has to market share — and most brands have never measured it.

How it is measured

Four steps, one number.

Nothing modelled, nothing estimated.

01
Define the category
Forty-plus buying prompts your customers actually type, generated for your category and edited by you.
02
Run every engine
Each prompt runs against ChatGPT, Perplexity, Gemini, Claude and Copilot, and the full answer is stored.
03
Count the names
Every vendor named in every answer is extracted, including competitors you did not list.
04
Weight and report
Mentions are weighted by prompt volume and reported per engine, per competitor, over time.
What you get

Six views on one metric.

Share of voice is only useful when you can break it apart.

Category share

One headline percentage, per engine and blended, with movement since the last run.

Head-to-head

Up to five competitors scored on the identical prompt set in the same runs.

Prompt clusters

Share split by intent — comparison, pricing, integration, security — so you can see where you are weak.

Position within the answer

Named first, named third or mentioned in passing. Order matters more than presence.

Sentiment and framing

Whether you are the recommendation, the cheap option or the caveat.

Board-ready export

One page, PDF or CSV, with the underlying answers linked.

Against the old metric

Why not just track rankings?

They measure a different channel.

About the metric.

No industry standard exists yet. We publish our exact method and store every answer, so you can audit any number rather than trust it.

In most categories the leader holds 40–60% and the fourth vendor under 10%. The useful target is beating your nearest rival, not a universal benchmark.

Forty is enough for a stable figure in most categories. Below twenty, single answer changes swing the number too much.
