Social share of voice (SOV) measures the percentage of total social media conversation about a brand category that mentions your brand versus competitors, serving as a proxy for brand dominance and awareness.
Quick Answer
Social share of voice (SOV) measures the percentage of total social media conversation about a brand category that mentions your brand versus competitors, serving as a proxy for brand dominance and awareness.
Brands with SOV above their market share (positive ESOV) tend to grow, SOV is a leading indicator of market share trajectory.
Calculate SOV monthly for your full competitive set to identify early trends in brand conversation dominance.
Quality-adjusted SOV (weighting high-engagement mentions) provides a more meaningful competitive benchmark than raw mention volume.

How Social Share of Voice (SOV) Works
Social share of voice is calculated as: (brand mention volume ÷ total mention volume for all brands in the category) × 100. For example, if your brand has 2,000 social mentions per month and the combined competitive set has 10,000, your SOV is 20%. The metric originates in traditional advertising (Share of Voice = your media spend ÷ total category media spend) but has evolved to encompass organic social conversation, news coverage, and brand mentions across all digital channels. Some frameworks distinguish between paid SOV (ad impression share), earned SOV (organic mentions and press), and owned SOV (brand content reach).
Why Social Share of Voice (SOV) Matters for B2B Marketing
Empirically, the relationship between share of voice and market share is one of the most validated findings in marketing science: brands with SOV above their market share tend to grow (excess share of voice, or ESOV), while brands with SOV below their market share tend to decline. Byron Sharp's research at the Ehrenberg-Bass Institute established a rough 10:1 rule, for every 10 points of ESOV, a brand tends to gain approximately 1 percentage point of market share over a 12-month period. While this relationship was documented in traditional media, digital SOV tracking provides B2B marketers with a more accessible proxy for brand trajectory.
Social Share of Voice (SOV): Best Practices & Strategic Application
To measure social SOV for B2B: define your competitive set (typically 5-10 direct competitors), use a social listening tool to capture mention volumes for all brands over the same time period, calculate each brand's percentage of total, and track monthly to identify trend lines. Weight mentions by engagement (a mention with 500 retweets carries more weight than one with 0) for a quality-adjusted SOV metric. Compare SOV against market share data from analyst reports or revenue-based proxies to calculate your ESOV position.
Agency Perspective: Social Share of Voice (SOV) in Practice
SOV benchmarking is particularly valuable for content investment decisions. If a B2B brand holds 8% SOV in a market where it holds 15% market share, the negative ESOV is a signal that content and organic social programs are under-invested relative to competitive activity. We use SOV trend data to make the business case for content marketing budget increases, connecting share-of-voice movement to market share growth expectations grounded in marketing science.
Frequently Asked Questions: Social Share of Voice (SOV)
Social share of voice (SOV) measures the percentage of total social media conversation about a brand category that mentions your brand versus competitors, serving as a proxy for brand dominance and awareness.
Social SOV measures brand conversation volume across social platforms and web mentions. Share of search measures relative branded search volume on Google (how often people search for your brand vs competitors). Both are leading indicators of brand awareness and market share, and they often move together, but share of search is more directly tied to purchase intent while social SOV reflects broader awareness and conversation momentum. Use both for a complete brand health picture.
The target is to achieve SOV at least equal to your market share, and ideally 10-20 points above it for sustained growth. If you hold 15% market share, a 25% SOV target is ambitious but directionally correct. In fragmented markets with 10+ competitors, even a dominant brand may target 20-30% SOV. The competitive baseline matters more than an absolute number, track your SOV versus each specific competitor to identify where conversation is being won or lost.
Yes, particularly in niche subniche conversations. SOV is audience-specific, a small SaaS company can dominate share of voice in conversations specifically about their category (e.g., "project management for construction teams") even while a larger competitor dominates the broader category. Niche SOV leadership in high-intent conversations often translates to disproportionate inbound opportunity relative to category-wide SOV investment.
