Share of Voice for Growth Marketers
DIRECT ANSWER
Share of Voice (SOV) is the percentage of total category advertising or content impressions that a brand owns relative to all competitors in the category. It is calculated as a brand's impressions (or spend, or mentions) divided by the total impressions across all category competitors. Higher SOV is consistently associated with sustained or growing market share. For Growth Marketers, this is especially relevant because running high-frequency experiments across channels without a team to execute each one.
What share of voice means for Growth Marketers
Growth marketers live in experiment cycles — hypothesis, test, measure, iterate. The constraint is always execution velocity: not enough hours to run the tests fast enough to find the winners. Growth stalls when the test queue backs up.
For a growth marketer, share of voice is a lever you need but rarely have time to execute consistently. Paid SOV is measured by comparing your ad impressions or spend against total category spend — tools like Google Ads' Impression Share report provide this directly for search. Organic SOV tracks the share of non-branded keyword rankings your domain holds versus competitors. Social SOV measures branded mention volume relative to competitor mention volume.
