Share of Voice in Growth Marketing
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. In Growth Marketing specifically, this means Maintain a prioritized experiment backlog (ICE-scored: Impact, Confidence, Ease) across all funnel stages and Design A/B and multivariate tests for landing pages, onboarding flows, and CTAs — all of which Hadrian's Growth Marketing Agent executes autonomously on your live data.
What share of voice means in Growth Marketing
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.
