What Is Share of Voice?

Share of voice (SOV) is the percentage of total visibility or mentions your brand earns in a market or channel compared to competitors, indicating your relative presence and authority.

Share of Voice Definition:

Share of voice measures the portion of attention your brand captures across marketing and search channels—such as paid ads, organic search, social media, PR, and answer engines—compared to competitors. Expressed as a percentage of total mentions, impressions, or spend, it provides insight on how visible and influential your brand is within its competitive landscape.

A higher SOV often correlates with stronger brand awareness, greater authority, and potential market share growth, making it a key metric for improving discoverability in both traditional and AI search.

How Does Share of Voice Differ from Market Share?

Share of voice measures brand visibility or presence in marketing channels, while market share measures actual sales or revenue. SOV is about attention; market share is about business results.

Types of Share of Voice

Share of voice can be segmented by channel or methodology, allowing teams to benchmark performance and prioritize strategies.

The main types include:

• Paid Media SOV: Based on ad spend or impressions in digital and traditional advertising. Paid search share of voice is the paid slice of this total.

• Organic SOV: Reflects visibility in organic search results, often measured by keyword rankings and estimated traffic share. Organic share of voice captures this earned search visibility.

• Social SOV: Tracks brand mentions, hashtags, and engagement across social platforms.

• AI SOV: Measures how frequently AI models mention or cite your brand compared to competitors in answer engines and LLM-powered platforms. AI share of voice is the fastest-growing type as buyers shift to answer engines.

How Is Share of Voice Measured?

Share of voice can be measured across both digital and traditional channels, each offering unique insights into brand presence and competitive position. Modern tracking goes beyond advertising to include organic, earned, and AI-driven visibility.

Common measurement channels include:

• Paid media: Tracks ad impressions, spend, and placements in digital and offline advertising to calculate your brand’s share versus competitors.

• Organic search: Measures keyword rankings, SERP features, branded search queries, and estimated traffic share from search engines. Search engine share of voice benchmarks this against every competitor ranking for the same terms.

• Social media: Monitors brand mentions, hashtags, and engagement across platforms such as X, LinkedIn, and Instagram.

• Public relations (PR): Counts editorial coverage, news mentions, and third-party references in traditional and digital outlets.

• AI answer engines: Measures how often AI search platforms (e.g., ChatGPT, Gemini, Perplexity) cite, link to, or mention your brand in response to relevant queries. AI search share of voice turns these citations into a percentage you can track.

According to BrightEdge Research, Google’s AI Overviews appeared for roughly 84% of queries in early U. S. rollout analysis—highlighting the importance of tracking share of voice in AI-powered results.

Example: Your ads received 1M impressions, and total competitor impressions were 10M → SOV = 10%.

Organic Search: Measure your share of total keyword rankings or estimated traffic.
Example: Your domain ranks for 500 of the 5,000 tracked keyword impressions → SOV = 10%.

Social Media: Track mentions, hashtags, or engagement volume compared to competitors.
Example: Your brand had 2,000 mentions out of 20,000 total → SOV = 10%.

PR Coverage: Count the number of news mentions, editorial placements, or backlinks across media outlets.

AI Answer Engines (ChatGPT, Perplexity, Gemini): Measure how often AI systems cite or mention your brand compared to competitors in AI-generated answers.‍
Example: Your brand appears in 120 of 1,000 total AI answers within your category → AI SOV = 12%.
