Share of voice is a relative metric. It says how much of the conversation about the category belongs to each of the compared brands, based on recent online mentions. It doesn't include sentiment analysis.
Who is being talked about most in this group right now, and how big the gap is.
Whether the talk is positive, whether it reached anyone who matters, and whether a rival's sudden spike came from a campaign or a crisis.
The free tool gives the simple check-up. Brand24 gives the exact mentions that made it, the sentiment analysis, the key sources in the comparison, and the SOV trends tracked every day instead of once.

The formula itself is simple. But the share of voice formula is influenced by two decisions you make before you apply it: what counts as a mention, and who counts as a competitor.
Your mentions divided by the total mentions of every brand in the comparison, times one hundred.
Share of voice is defined by the set you compare against. Compare against the brands you actually compete with.
News sites, blogs, forums, review sites, video, podcasts and social media platforms.
A brand named after a common word collects mentions that have nothing to do with it.
Compare specific campaigns. A week that contains your product launch is not comparable to a quiet one.
One reading is a baseline, not a verdict. Measuring share of voice becomes more useful when monitored over time.
Two brands can hold the same share of voice and be in completely different health. Share of voice percentage tells you nothing about tone. It takes sentiment to tell you whether SOV is working in your favor.
Because it is one of the few marketing numbers with a direct link to growth, and it puts your own results in the context that matters: your competition.
Mentions up 20% sounds like a win until you learn the category grew by forty. Share of voice is the version of that number that gives more insight.
A launch that moves your share of voice reached people outside your audience. If the campaign moved only your mention count, it may have reached no one new.
A competitor starting to dominate the share of the conversation usually shows before it would hurt your revenue. It's a very useful early input for crisis management planning.
The best-known work on this comes from the IPA databank, analyzed by Les Binet and Peter Field. They found a consistent relationship between holding a share of voice above your share of market and growth in the market share. Every 10 percentage points of ESOV typically delivers approximately 0.5% market share growth per year.
Marketers use this excess share of voice figure for competitive benchmarking and to justify PR budget and resource allocation decisions to the rest of the business.

They need a competitive number for PR efforts and for understanding the competitive landscape.
A share of voice split is the fastest way to show a client where they stand against their rivals, in one simple number.
They need to know whether they are being talked about at all, and who is getting the attention they want.
They get a real competitive measure for a case study or a thesis, taken from live public mentions.
Three metrics that sound alike and answer different questions. Mix them up, and you can easily mess up the conclusion from a campaign.
Measures visibility and conversation. This is what the tool on this page gives you.
Your part of the category search engine results.
Your part of category revenue, and the clearest read on overall market position.
AI engines like ChatGPT answer based on the same public mentions this calculator counts. ChatGPT alone now answers questions for 900 million weekly users. High SOV means better chances of getting mentioned in them.
This means ranking well no longer guarantees a place in the answer. The brands that keep showing up in ChatGPT and other AI tools are usually the ones with the most public mentions.

Yes. There is no account, no card needed, and no trial. You type in the brands, and you calculate the share of voice.
Because share of voice is a share of a broader category. One brand on its own is always one hundred percent of itself, which tells you nothing. The metric only carries meaning against a named set of competitors.
If you want a single brand's visibility measured on its own, the Brand Awareness Tracker in the tools menu is the one you want.
Two at a minimum and five at a maximum, so your brand plus up to four competitors.
Yes. Anything people write about works: a product line, a campaign hashtag, a public figure. Keep the keywords relevant, because a broad one next to a narrow one will always look dominant.
Every result has its own address, so copying the link is enough to send someone the exact comparison you are looking at. You can also download the result as an image or a PDF.
A public piece of content that names the brand. Brand24 collects across news sites, blogs, forums, review sites, video, podcasts and social media platforms.
Private messages and closed groups are not included, and no tool can see them.
Measuring the share of voice is done by dividing your brand's mentions by the total mentions of every brand in the comparison, then multiply by one hundred: (Your mentions ÷ Total mentions) × 100.
This free calculator runs that formula for you.
There is no universal good number, because it depends entirely on who you put in the comparison. The useful benchmark is your own share of the market if you hold twenty percent of the category revenue and ten percent of the conversation.
The second benchmark is your own last reading. Consistency in growth and an overall SOV percentage higher than most competitors is favorable.
It means every mention in the comparison went to one brand: yours. In a two-brand comparison, that would mean your competitor returned no public mentions at all over the period measured.
It tells you how much of the conversation in your category belongs to you, relative to the competitors you chose to measure against. AI Share of voice is narrowed to LLMs.
On its own, it says nothing about the tone or quality of that attention. Pair it with sentiment analysis to know whether being talked about is working in your favor.
Usually, the brand name is also a common word, so the count picks up conversation that has nothing to do with the brand. Names like Apple, Shell, Orange, Gap and Visa all have this problem.
The free calculator matches the name as typed. Separating the brand from the word needs filtering in the full platform.
No, and this is the most important limit of the metric. A brand in the middle of a scandal can hold the largest share of voice in its category.
Ignoring sentiment here is the most common reading mistake: a rising share of voice paired with negative sentiment can mean a brewing PR crisis. Sentiment is the metric that answers that question, and is available in the full platform.
It means we found no recent public mentions we could attribute to that name.
We show it as no data rather than as zero percent on purpose, because those are different statements and only one of them would be honest.
From Brand24's own social listening and media monitoring data collection, the same source the paid platform uses. The free calculator runs a narrower version of it: current counts only, no history, no filters and no access to the mentions.
It is built from recent mentions and cached for a few hours, so a popular comparison may be served from cache rather than recalculated for every visitor.
Not in the free calculator. It gives you one reading, taken now. Tracking the same split day after day, which is where the metric earns its keep, is what the full platform is for.
Not here. The free calculator measures the whole public web at once, which is the right default but the wrong lens for a brand that only trades in one market. Filtering by country, language, source type or date range is in the full platform.
Monthly suits most brands, with a closer look around a launch, paid advertising, or a competitor's big moment.
The ones your customers mention in your category, which is usually a shorter list than the one in your strategy deck. Two useful sets:
Run them as two separate comparisons. Mixing a giant in with your peers flattens everyone else into a rounding error.
Check which of two things happened, because they call for opposite responses. Either your own coverage fell, or a rival's rose while yours held steady.
For most questions, yes. Followers count the audience you already own, and that number can sit still for years while your standing in the market changes underneath it. Share of voice counts people choosing to talk about you, including people who do not follow you at all.
Three levers tend to move it fastest: a consistent content strategy instead of one-off campaigns, showing up in the industry conversations your category is already having, and using social listening tools to find where those conversations are happening before you join them.
Yes. AI engines answer brand questions using public mentions across the web (the same mentions this calculator counts). With ChatGPT alone answering 900 million weekly users, a bigger share of voice means more raw material for AI models to cite you by name instead of a competitor.
