Share of voice is one of the most useful metrics in a communications and marketing toolkit. It’s also one of the most misunderstood. If you’ve ever wondered how your brand stacks up against competitors, not just in sales but in visibility, conversation, and presence, this is the metric that answers that question. This guide covers everything you need to know: what share of voice is, why it matters, how to calculate it, and how to grow it.
What is share of voice?
Share of voice (SOV) is a metric that measures how much of the total conversation, visibility, or advertising presence within a given market or channel belongs to your brand compared to your competitors. It is expressed as a percentage of the whole, your slice of the total industry pie.
Unlike vanity metrics such as follower counts or raw impression numbers, SOV is inherently competitive. It only means something in relation to others. For example, a brand with 10,000 monthly mentions looks very different depending on whether total industry mentions are 20,000 or 2,000,000.
SOV is also channel-agnostic. It applies equally to social media conversations, paid advertising, organic search visibility, and PR coverage. The underlying principle is the same across all of them: how much of the available space does your brand occupy?
Why does Share of Voice Matter?
SOV matters because it tells you something no internal metric can: where you stand relative to your market, not just relative to last month.
There are three core reasons to track it.
- It reveals your competitive position
Your engagement rate or website traffic only tells you how you’re performing in isolation. SOV shows you whether you’re gaining or losing ground against the brands competing for the same audience. - It predicts future growth
Research consistently shows that brands which maintain a share of voice above their share of market tend to grow into that gap over time. If your brand owns 35% of the conversation but only holds 25% of the market, the data suggests you’re in a growth position. Whereas, in the reverse, a high market share and declining SOV, is a warning sign worth taking seriously. - It reflects brand health and messaging effectiveness
When your SOV grows, it generally means your content is resonating, your PR is landing, and your campaigns are cutting through. When it stalls or falls, that’s a signal to investigate.
One important distinction: SOV is not the same as brand awareness. Awareness is an absolute measure: it asks “do people know you exist?” SOV is a competitive measure: it asks “relative to your competitors, how present are you?” Both matter, but they answer different questions.
At Onclusive, we see this dynamic play out daily. Our media monitoring platform processes more than 28 million earned media items daily, giving us a uniquely data-driven perspective on how voice translates into influence and impact. The brands that treat SOV as a strategic priority, not just a reporting metric, are consistently the ones that outpace their competitors over time.
Share of voice vs. share of market
These two metrics are related but measure fundamentally different things, and confusing them is a common mistake.
Share of market (SOM) is a lagging indicator. It measures actual sales or revenue as a percentage of the total market. It answers the question: how much do we sell?
Share of voice (SOV) is a leading indicator. It measures visibility and conversation. It answers the question: how much are we talked about?
The strategic relationship between them is what makes SOV so valuable. Think of it this way: SOV is the demand you’re building today and SOM is the result you’ll see tomorrow. Brands that consistently maintain a higher SOV than their SOM tend to grow into that gap. Brands that let SOV slip below their market share are often conceding ground to more visible competitors, even if their sales figures haven’t shown it yet.
How to calculate share of voice
The formula is straightforward:
SOV % = (Your brand mentions ÷ Total industry mentions) × 100
Here’s how to apply it in four steps.
Step 1: Define your competitive set. Decide which competitors you’re measuring against. This should reflect your real market: the brands your audience actually considers alongside yours.
Step 2: Choose your channel and time frame. SOV is channel-specific, so decide whether you’re measuring social media, PR or earned media coverage, paid advertising, or organic search. Set a consistent time frame; 30 days or a quarter works well for most purposes.
Step 3: Gather your data. Count total brand mentions (or the relevant metric) for your brand and for each competitor in your set.
Step 4: Apply the formula. Add all mentions together to get your total industry figure, then divide your own mentions by that total and multiply by 100.
Worked example: Your brand receives 200 mentions in a given month. Your three main competitors receive 150, 250, and 200 mentions respectively. Total industry mentions = 800. Your SOV = (200 ÷ 800) × 100 = 25%.
The formula works the same way regardless of channel. Simply swap “mentions” for the relevant metric. For paid advertising, use ad impressions. For organic search, use keyword visibility scores. For PR, use coverage volume or estimated reach.
What can you measure SOV across?
SOV is not a single-channel metric. The brands that get the most value from it track it across multiple dimensions simultaneously.
Social media: brand mentions, hashtag usage, and conversation share across platforms. Social SOV captures how much of the organic conversation in your category your brand is part of.
Paid advertising: share of ad impressions or spend within a category. Google Ads calls this impression share and surfaces it natively within your account.
Organic search: share of keyword visibility or click-through traffic compared to competitors. This is often tracked using SEO tools that show your ranking coverage across a defined keyword set.
PR and earned media: share of press coverage, broadcast mentions, and editorial backlinks. This is where volume, reach, and sentiment all matter, not just the number of mentions.
Retail and e-commerce: where relevant, SOV can also apply to platform placement, such as sponsored and organic visibility on Amazon or other retail media networks.
Tracking across channels gives you a fuller picture. A brand may dominate social but be nearly invisible in search, and both gaps matter to how customers discover and evaluate you.
What is a good share of voice percentage?
There is no universal benchmark for what ‘good’ looks like. The right number depends on how many meaningful competitors exist in your market.
As a general rule: In a market with three or four major players, a 25–30% SOV indicates a strong position. In a more fragmented market with ten or more active competitors, 15% could represent clear leadership.
The more useful benchmark, however, is your own trend over time. Are you growing or declining? Is your SOV keeping pace with your investment in content, paid media, and PR — or falling behind it?
The clearest strategic signal is the relationship between your SOV and your share of market. If your SOV exceeds your share of market, your brand is in a growth position. If it falls below, that gap is worth closing before it shows up in your revenue figures.

How to increase your share of voice
Growing SOV requires consistent effort across multiple channels. These strategies, applied together, are where sustainable gains come from.
Understand your audience deeply
SOV grows when your content earns attention, and attention follows relevance. Before investing in volume, make sure you understand what your audience actually cares about and align your messaging accordingly.
Create consistent, high-quality content
Frequency and quality together drive mentions and shares. Irregular publishing or low-value content rarely generates the kind of organic amplification that moves SOV meaningfully.
Diversify your channel presence
Concentrating on a single platform creates a single point of failure. Expanding your presence across social, search, and earned media compounds your visibility over time.
Engage actively with your community
Passive publishing does not build SOV. Responding to comments, participating in industry conversations, and acknowledging mentions all increase the likelihood that others will amplify your voice.
Invest in SEO
Organic search is one of the most scalable and measurable components of SOV. Building topical authority through well-structured content improves your share of keyword visibility in ways that compound over months and years.
Leverage PR and earned media
Third-party coverage in credible publications carries reach and authority that owned content cannot replicate. A consistent PR strategy built on original research, expert commentary, and rapid response to news drives meaningful SOV growth.
Partner with relevant influencers
Influencer partnerships allow you to borrow established audiences and bring your brand into conversations you wouldn’t otherwise be part of.
Monitor, analyse, and iterate
SOV data is only useful if you act on it. Review it regularly, understand what’s driving changes, and adjust your strategy accordingly.
Common mistakes in SOV analysis
Getting the measurement right matters as much as the strategy. These are the pitfalls most likely to distort your results.
Treating all coverage as equal
A mention in a niche trade blog is not equivalent to coverage in a national outlet. Volume alone can be misleading. Reach, authority, and audience relevance all affect how much a mention is actually worth.
Measuring volume while ignoring sentiment
High SOV with predominantly negative sentiment is not a win. If your brand is being talked about mostly in the context of complaints or criticism, that needs to surface in your analysis alongside the volume figure.
Focusing on a single channel
If you only track social media SOV, you may be missing the fact that a competitor is quietly building dominance in search or earning significantly more press coverage. A single-channel view distorts the real picture.
Failing to establish a baseline before a campaign
Without a starting point, you cannot measure impact. Before any major campaign or activity, record your current SOV across the channels you plan to measure.
Is share of voice a KPI?
Yes — when it is tied to a measurable goal. SOV becomes a meaningful KPI when you use it to track progress toward specific outcomes such as:
- Increasing brand awareness
- Improving competitive positioning
- Growing organic search visibility over a defined period
It sits within the awareness pillar of most marketing KPI frameworks. Critically, it is a leading indicator. It predicts future outcomes rather than measuring past ones. That makes it particularly valuable for brands that want to get ahead of market shifts, not just report on them.
Frequently Asked Questions About Share of Voice
How do you define share of voice?
Share of voice is a competitive metric that measures your brand’s percentage of total visibility, mentions, or advertising presence within a given market or channel. It shows how much of the available conversation or space your brand occupies relative to competitors.
What is an example of share of voice?
If your brand receives 300 mentions in a month and the total mentions across your brand and all key competitors amount to 1,000, your share of voice is 30%. The same logic applies in paid advertising (using impression share), organic search (using keyword visibility), and PR (using coverage volume).
How do you calculate share of voice?
Divide your brand’s mentions (or relevant metric) by the total mentions across your competitive set, then multiply by 100. For example: 200 mentions ÷ 800 total mentions × 100 = 25% SOV. The formula is the same across channels — only the metric changes.
What does 100% share of voice mean?
A 100% share of voice means your brand accounts for all of the measurable conversation, visibility, or advertising presence in a given market or channel during a specific period. In practice this is rare outside of very niche categories or highly targeted paid campaigns. In paid advertising, platforms sometimes offer “share of voice” buys that give a single brand exclusive presence in a defined context.
What is the difference between SOV and SOI (Share of Impact)?
Share of voice measures visibility: how often your brand appears across conversations, search results, or media coverage. Share of impact (SOI) goes a step further by weighting that visibility against the quality, reach, and influence of each mention. A brand with high SOV but low SOI is getting lots of mentions that aren’t moving the needle. Both metrics are useful, but SOI gives you a more nuanced picture of whether your visibility is actually driving influence.
Is share of voice the same as brand awareness?
No. Brand awareness is an absolute measure. It reflects what percentage of your target audience recognises or recalls your brand. Share of voice is a relative, competitive measure — it shows how visible your brand is compared to competitors. The two are related: sustained high SOV tends to build awareness over time. But you can have strong brand awareness and declining SOV, which often signals that competitors are gaining momentum.
