Share of Voice (SoV)
The share of LLM answers in your topic where a specific brand is named.
Competitor-relative: if you and three rivals split mentions 40/30/20/10, your SoV is 40%.
Definition
Share of Voice (SoV) in the LLM context is the percentage of answers in a given category where a brand is mentioned, compared to its competitive set. It is the classic paid-media and SEO metric adapted to generative answers: instead of impressions on a SERP, the denominator is the set of LLM responses to your prompt pack.
How it's computed
For each prompt we collect answers from every model in your coverage. A brand is counted once per answer regardless of how many times it is mentioned. SoV = brand mentions ÷ total answers with at least one brand mention × 100%. Getllmspy computes SoV per model, per topic, per week so you can see where you are gaining or losing ground.
How to read it
SoV is always competitor-relative. A 35% SoV is strong in a market with ten equals and weak in a duopoly. Watch the trend, not the absolute value: a 5-point weekly drop is a signal, even at 60%.
Industry benchmarks
In highly contested spaces (SaaS, fintech, e-commerce), SoV above ~25% is usually strong. In smaller B2B, industrial, or regional categories, 40–50% can be realistic after 3–4 months of focused GEO work.
Important: SoV is computed only within your chosen competitor basket. Adding a new rival mechanically lowers everyone’s SoV — do not confuse that with a true visibility loss.
Share of Voice (SoV) vs LLM-Score
LLM-Score evaluates quality of mention (correctness, sentiment). SoV evaluates quantity of mention vs competitors. Use both: high SoV with low LLM-Score means LLMs talk about you a lot but get it wrong.
When to use
- Competitive benchmarking each quarter.
- Measuring the impact of a PR or backlink campaign.
- Picking which models to prioritize (go where your SoV is worst).
