What is Share of voice (AI)?
Your slice of the citations for a topic versus competitors.
Share of voice (SoV) in AI search is your citation count divided by the combined citations of you plus your named competitors, for a given prompt and engine. It converts a yes/no (“were you cited”) into a scoreboard you can move, and it is most useful as a trend and a comparison.
Because each engine cites a different mix of sources, SoV is tracked per engine, winning ChatGPT does not mean you won Gemini. CiteTrack rolls it into the narrative-control map. Deeper explainer: share of voice, explained.
Why — and when — does it matter?
Share of voice answers a competitive question: of the citations or recommendations available in the tracked market, how much did each brand earn?
How it works
Define named competitors and eligible prompts.
Collect citations consistently by engine.
Choose domain share, citation share or prompt-win share and label it.
Calculate by segment before an overall roll-up.
Trend an unchanged methodology.
Worked example
A brand has 41% overall SoV but only 12% on purchase prompts. The segment view prevents a strong informational footprint from hiding a weak buying position.
How to track and report it
Reporting rule: State the engine, prompt set, market, time window and denominator. A number without scope cannot be reproduced or compared.
Practical playbook
- Define named competitors and eligible prompts.
- Collect citations consistently by engine.
- Choose domain share, citation share or prompt-win share and label it.
- Calculate by segment before an overall roll-up.
- Trend an unchanged methodology.
Common mistakes
- Leaving the competitor set undefined
- Combining mentions and citations
- Celebrating share growth caused only by a smaller sample
