What Is Share of Voice (SOV)?
Share of Voice (SOV) measures how much of a market your brand owns relative to the competition for a chosen metric. It is widely used in marketing, advertising, PR, SEO, and social media to gauge brand visibility and dominance. Whatever metric matters to you — ad spend, impressions, social mentions, organic search clicks, or media coverage — SOV expresses your slice as a percentage of the total.
How to Use This Calculator
Enter two numbers: Your Brand Metric (your brand's value for the chosen metric) and the Total Market Metric (the combined value across all brands, including yours). The calculator returns your Share of Voice as a percentage, plus the remaining share held by competitors or other sources. Make sure both numbers use the same unit and time period for an accurate result.
The Formula Explained
The math is simple division turned into a percentage:
$$\text{SOV} = \frac{\text{Your Brand Metric}}{\text{Total Market Metric}} \times 100\%$$
The numerator is your brand's portion; the denominator is the whole market. Multiplying by 100 converts the ratio into a percentage that is easy to compare over time or against competitors.
Worked Example
Suppose your brand earned 25,000 social media mentions last month, while the entire industry — your brand plus all competitors — generated 100,000 mentions. Your Share of Voice is $$(25{,}000 \div 100{,}000) \times 100 = 25\%$$ That means competitors and other sources hold the remaining 75%.
FAQ
What metrics can I use? Any quantifiable, comparable metric works: ad spend, impressions, clicks, mentions, backlinks, keyword rankings, or earned media value.
Is a higher SOV always better? Generally yes — higher SOV signals stronger market presence. Many marketers track SOV against market share, since a Share of Voice greater than your market share often predicts future growth.
What if I don't know the total market metric? Estimate it by summing your brand's metric and your top competitors' metrics. The total must include your own brand to keep the percentage accurate.
