What is Share of Voice (SOV)?
Learn what Share of Voice (SOV) means, why it matters for search rankings, and how consistent content publishing keeps your business visible in Google.
Definition
Share of voice (SOV) is a marketing metric that measures your brand's visibility in organic search relative to competitors. Expressed as a percentage of.
What is Share of Voice (SOV)?
Share of voice measures the portion of total organic search visibility your brand captures compared to competitors for a specific set of keywords.
If 4 companies compete for the same 100 keywords and your site captures 35% of all possible organic clicks, your SOV is 35%. Think of it as your market share. But for search results instead of revenue. Tools like Ahrefs, Semrush, and Sistrix calculate SOV by combining ranking positions, search volumes, and estimated click-through rates.
A study by Les Binet and Peter Field found a strong correlation between share of voice and market share across industries. Brands whose SOV exceeds their market share tend to grow. Brands whose SOV trails their market share tend to shrink. The data holds for organic search just as it does for advertising.
Why Does Share of Voice Matter?
SOV tells you whether you’re winning or losing the search battle. And by how much.
- Competitive benchmarking. Know exactly which competitors own more of the search landscape than you do
- Predicts market share growth. Brands consistently outspending their market share in SOV tend to capture more customers over time
- Identifies keyword gaps. Comparing your SOV by topic cluster reveals where competitors dominate and where you have opportunities
- Measures SEO ROI. Tracking SOV monthly shows whether your content investment is gaining ground against the competition
SOV is especially valuable for businesses in competitive local markets where multiple providers fight for the same local keywords.
How Share of Voice Works
Calculation Method
Define a keyword set that represents your market. For each keyword, determine which site ranks and at what position. Apply estimated CTR per position and multiply by monthly search volume. Your SOV is your total estimated clicks divided by the total estimated clicks across all competitors.
Tracking Over Time
SOV is most useful as a trend line. A single snapshot tells you where you stand. Monthly tracking tells you whether you’re gaining or losing ground. Significant SOV gains usually correlate with traffic and revenue increases 3-6 months later.
Improving SOV
Publish more content targeting keywords where competitors currently own the rankings. Strengthen existing pages that rank on page 2. Earn more backlinks to boost authority. The math is simple: rank for more keywords at higher positions, and your SOV goes up.
Share of Voice Examples
Three dental practices in Denver compete for 50 local keywords. Practice A has 42% SOV (ranks #1-3 for most terms). Practice B has 28%. Practice C has 12%. Practice C starts publishing 30 articles per month through theStacc, targeting the keywords where they have zero visibility. Within 6 months, their SOV jumps to 31%. Flipping their position with Practice B.
A SaaS company tracks SOV across 5 topic clusters. They dominate “project management” (38% SOV) but trail badly in “team collaboration” (8% SOV). This data directs their content strategy: shift resources to the weak cluster where the opportunity is greatest.
Frequently Asked Questions
How do I calculate share of voice for SEO?
Use Ahrefs, Semrush, or a similar tool. Define your keyword set, add your domain and competitor domains, and the tool calculates visibility percentages for each. If you don’t have paid tools, manually track rank positions for 20-50 core keywords and estimate CTR.
What’s the difference between SOV and search visibility?
Search visibility measures your click share in isolation. SOV compares your visibility to competitors’ visibility. It’s a relative metric. High visibility means you’re capturing clicks. High SOV means you’re capturing more clicks than the competition.
How often should I check SOV?
Monthly tracking works for most businesses. SOV doesn’t shift dramatically week to week. Monthly data points reveal trends early enough to act on. And smooths out the daily ranking fluctuations that make weekly tracking noisy.
