Share of Voice: definition, calculation and what the metric shows
Sascha Kirstein
Short definition
Share of Voice (SOV) is a brand's percentage of all coverage or mentions within a defined set of competitors, channels, market and period. It measures relative presence, not reputation, attention or impact.
Also known as: SOV, SoV, Share of Model
Share of Voice is the slice of a defined conversation that belongs to your brand. An example: a six-week analysis finds 42 mentions of your company and 58 mentions of the competitors you chose. Your Share of Voice is then 42 percent. The figure is simple and easy to compare. What it tells you depends on how it was produced.
The formula
Share of Voice = mentions of your brand ÷ mentions of all compared brands × 100
Instead of mentions, a report can count articles, airtime or estimated reach. Each unit gives a different but valid result. What matters is that the report says which one it used and keeps it stable over time.
The reach-based version is especially telling. You scale each mention by the outlet's estimated readership. A cover story in the leading trade title then counts for more than twenty passing mentions in small blogs.
The AMEC Taxonomy of Evaluation files Share of Voice under outputs. It describes how coverage was distributed. It does not describe what the audience noticed or thought.
What Share of Voice teaches you
The share on its own is just a number. It gets interesting when you look at the coverage behind it:
- Which topics do your competitors own?
- Which outlets do they appear in?
- Which journalists write about them?
From that you can decide whether to play the same topics. Or whether to stay out of a topic on purpose. Our article on competitive media tracking by region shows how to set this up country by country.
What to watch for when reading it
The number is not wrong in itself. But it misleads when the report leaves out what defines it. Five points come up often:
- The competitor set is chosen to flatter. Drop the strongest rival and your share rises. Nothing in the coverage has changed. Changing the set also breaks the trend line.
- Bad news counts as voice. A product recall or a lawsuit can push Share of Voice to a record high. Without tone next to it, a crisis looks like a success.
- Every mention weighs the same. A passing mention counts as much as a cover story. The reach-based version corrects for that.
- The universe is unclear. "Share of Voice in the market" means nothing unless the report names topics, channels, languages and dates. A total across several countries can also hide that the brand trails far behind in one of them.
- Presence is read as impact. A higher share does not mean more awareness, preference or sales. Those need audience research or business data.
None of these is a reason to drop the metric. They are reasons to report it with its method.
How to report Share of Voice so it holds up
State in the report:
- the topic or campaign
- every brand included
- market and language
- channels
- start and end date
- the counting unit and any weighting
Show tone within each brand's share, or place a sentiment analysis next to it. If you weight by reach, report the raw value beside it.
Share of Voice in AI answers
The same idea works for answers from ChatGPT, Gemini or Copilot. Here the base is a fixed set of questions. The count is how often each tracked brand is named in the answer text. Some teams call this Share of Model. It is not the same as citation share, which counts the sources an answer links to. A brand can dominate the text while its website is never cited. The reverse happens too. Both figures belong side by side in the report.

Frequently asked questions
Only when it is reported without its method. Share of Voice depends on the competitor set, the counting unit and the period. Reported with those details and with tone next to it, it is a useful output metric. Reported alone, it can make a crisis look like a success.
There is no general target. It depends on how many competitors you track and how the market is split. Compare your share with your own history under the same definition. Also watch whether the gap to the leading competitor narrows.
