How can you tell if your visibility today will translate into sales tomorrow? Consumer goods brands are competing for one scarce resource: attention. It is the very first step in the customer journey, laying the foundation for awareness, consideration, and ultimately leading to sales.
Two key metrics provide a compass in this battle: Share of Voice (SOV) and Share of Market (SOM). SOV reveals how visible your brand is, while SOM reflects the actual slice of the market you actually win. In this article, we will explain what these terms mean in the digital era, why they matter for growth, and how they can help guide your strategy across various platforms.
What’s the Difference Between Share of Voice and Share of Market?
Share of Voice (SOV) is a marketing metric that shows your brand's visibility compared to your competitors. This includes paid ads, PR & news, organic search, video views, social mentions, and marketplace placements. In simple terms, SOV answers the question: “How visible is my brand compared to others?”
Meanwhile, Share of Market (SOM) shows the proportion of your brand’s sales compared to other market players. It answers the question: “How much of the market’s revenue do we actually capture?”
The two are closely linked. When your SOV is higher than your SOM, you typically gain market share. Conversely, if SOV falls behind, market share often declines.
In addition, there are other supporting metrics worth noting:
- Share of Search: The proportion of category search queries that include your brand name. It’s a powerful predictor of market share.
- Share of Shelf: How frequently your products appear on the main pages of marketplaces such as Amazon.
Why Share of Voice Is Crucial for Growth
So, why does Share of Voice matter so much for your brand’s growth? Think of it this way: the more visible you are compared to your competitors, the more likely you are to win a bigger slice of the market. In fact, Marketing research points to a simple rule: SOV > SOM = growth. In other words, when a brand’s SOV is higher than its current SOM, sales growth usually follows.
For example, studies by Binet & Field found that for every 10% of your SOV exceeds your SOM, you can expect around 0.5% annual market share growth.
In the digital world, this link is even stronger. Studies reveal that your share of search can predict future market share with up to 83% accuracy. On marketplaces like Amazon, having a strong share of shelf is critical, as 70% of shoppers only browse the first page. And on social media, the more people talk about your brand, the more likely they are to consider it when making a purchase. In short: visibility today predicts sales tomorrow.
Key Digital Channels to Monitor SOV
You can track Share of Voice to any channel where your brand is mentioned. Let’s see how to measure it across different types of channels
- Google (Search): Monitor both organic keyword rankings, search visibility, and paid impression share.
- YouTube (Video): Measure your share of views and mentions across category content, reviews, and influencer videos.
- Amazon (Marketplace): Monitor both sponsored SOV (advertising) and organic SOV (page-one placements).
- TikTok (Social): Observe how often your brand appears in trending hashtags, brand mentions, viral clips, and engagement metrics, including likes, comments, and shares
- PR and media: Track your brand presence in news articles, press releases, industry publications, and other media outlets.
SOV + Branded Search: Upper-Funnel KPIs
The power of SOV becomes even clearer when combined with Branded Search, an online search query that includes your brand or product name. When the two are combined, it will become powerful upper-funnel KPIs.
Together, these metrics tell you if your campaigns are actually getting in front of people and whether you’re sparking enough curiosity for them to actively search your brand. In other words, you’re not just making noise, you’re building a real intent that paves the way for consideration and, eventually, sales.
Focus on Long-Term Trends
Share of Voice (SOV) and Branded Search work best when you evaluate them together and over time, rather than in isolation or through quick snapshots. Building awareness and winning consumer attention is a long game, and there’s often a natural delay between people noticing your brand and actually taking action. For instance, someone might see your ads today, which lifts your SOV, but only search for your brand weeks or even months later when they’re ready to buy.
By tracking these trends over time, you can see how an increase in SOV translates into higher branded search volumes and ultimately, growth in SOM. In this way, steady rises in SOV and branded search signal stronger brand equity, while declines serve as an early warning, long before sales. This long-term perspective is what makes SOV and branded search so valuable for strategic planning.
The Power of Channel Synergy
Digital channels don’t operate in silos. What you do in one place often creates a ripple effect, strengthening results elsewhere. Think of it like a halo effect: your actions on one platform can boost your brand across the entire customer journey.
For example, when a TikTok campaign goes viral, the impact doesn’t end with social buzz. It often sparks curiosity and drives people to search for your brand on Google. Those extra branded searches can then boost your visibility on marketplaces like Amazon, both in paid ads and organic rankings. Similarly, YouTube exposure can reinforce recall, making consumers more likely to click your ads.
Organic vs Paid SOV
SOV can be achieved in two ways: organically and through a paid campaign. Organic SOV is earned naturally over time, often through SEO, customer reviews, social mentions, and marketplace rankings. It represents the credibility and trust your brand builds without direct spending.
On the other hand, Paid SOV comes from advertising, sponsored placements, and influencer partnerships. This approach can give your brand an immediate boost in visibility, helping you reach new audiences more effectively.
Both approaches play a vital role. Paid SOV gives you a quick boost and instant visibility, while Organic SOV builds long-term sustainability and brand trust. If you really want to grow your SOV, you’ll get the best results by combining the two.
Real-World Case Studies
Global consumer brands have already proven the impact of managing SOV effectively:
- A personal care brand achieved +92% Amazon SOV, resulting in a 63% rise in conversion rate and a 213% increase in revenue by integrating paid and organic strategies.
- OTC brands increased SOV by 26% while reducing CPC by 15% using automation.
- Another brand launch campaign improved Share of Search by 42% and ROAS by 17% through smart budget allocation.
These cases illustrate how monitoring and optimizing SOV across channels leads to measurable growth in both visibility and market share.
So, curious about what we should discuss next?
