Share of Voice (SOV)
A brand's proportion of total advertising or organic visibility within a market, relative to competitors — a proxy for market presence and mind share.
Share of Voice (SOV) measures how prominently a brand appears across a market or channel relative to total competitor activity — the brand's 'slice' of total market visibility. Originally an advertising metric (share of total ad impressions in a category), SOV has expanded to cover: organic search SOV (percentage of keyword impressions captured vs. competitors), paid search SOV (impression share in Google Ads), social SOV (share of brand mentions across social platforms), and PR/media SOV (share of editorial coverage in target publications). Why SOV matters strategically: research shows that brands with SOV significantly above market share tend to grow, while brands with SOV below market share tend to decline — SOV predicts future market share. Measurement: Ahrefs and SEMrush calculate organic SOV across keyword sets; Brandwatch and Mention measure social SOV; Google Ads Auction Insights shows paid SOV. For B2B, organic SOV by keyword cluster is the most actionable metric — tracking what percentage of target keyword impressions your site captures vs. competitors reveals content gaps that can be systematically closed.
