Share of voice (social)

Share of voice on social is the portion of total mentions, impressions, or engagement in a defined category or conversation that belongs to one brand relative to its competitors.

Measured on Instagram, LinkedIn, X, and TikTok, share of voice is usually computed as: (your brand’s mentions or engagement) / (sum of mentions or engagement across the named competitive set). The competitive set defines the result — the same brand can have 40% share of voice in a narrow vertical and 2% in a broader category.

Useful share-of-voice tracking requires a defined competitor list, a defined keyword/topic scope, and a consistent measurement window. The number is mostly meaningful as a trend over time.

Share of voice is the leading indicator that owned-channel content strategy is working — before downstream metrics like signups or pipeline. It also surfaces who in the category is gaining audience attention.
