You're visible on 12 out of 20 tracked prompts. That sounds good. But your top competitor is visible on 18. And a newcomer you've never heard of just appeared on 9. Your visibility score says 60%. But your actual share of the AI recommendation market in your niche? It's closer to 25%.
Share of Voice tells you the part of the picture that absolute numbers miss: how much of the AI recommendation landscape you actually own.
What Share of Voice measures
Share of Voice in Mentionable is the proportion of AI recommendations that go to your brand compared to all detected competitors. It's not about whether you're visible. It's about how visible you are relative to everyone else in your space.
Every time Mentionable runs a tracking cycle, it captures every brand mentioned across all your tracked prompts on all selected LLMs. Your Share of Voice is your brand's mention count as a proportion of total mentions.
If there are 100 total brand mentions across your tracked prompts and your brand accounts for 25 of them, your Share of Voice is 25%. If a competitor accounts for 35, they hold more of the recommendation landscape than you do.
The donut chart: your position at a glance
Mentionable's Share of Voice donut chart gives you an instant visual of your competitive position. Your brand's share is highlighted, with competitors arranged around it. In one look, you know whether you dominate your niche or trail behind.
The donut chart captures the current snapshot: where things stand right now based on the most recent tracking cycle. It's the starting point for understanding your competitive position.
The bar chart: tracking momentum
The stacked bar chart shows how Share of Voice evolves over time. Each bar represents a tracking cycle, with segments showing each brand's share.
This is where the real strategy lives. A single snapshot tells you where you stand. The trend tells you where you're heading.
If your share grew from 20% to 30% over the last month, your optimization efforts are working. If a competitor's share jumped from 10% to 25%, something changed in their approach that's worth investigating. If a new brand appears in the chart that wasn't there two weeks ago, that's an emerging threat you should monitor.
Share of Voice by LLM
One of the most useful breakdowns is Share of Voice by individual LLM platform. Your brand might hold 40% share on Copilot (where depth of knowledge matters) but only 10% on Perplexity (where fresh, citeable content drives recommendations).
These platform-specific shares tell you where to focus:
- High share on ChatGPT suggests strong brand authority and topical coverage
- High share on Perplexity suggests your content is fresh, well-sourced, and citeable
- High share on Google AI Mode suggests solid traditional SEO foundations
- Low share on a specific LLM points to a targeted improvement opportunity
Platform share data helps you allocate effort where it'll have the most impact, instead of trying to improve everywhere at once.
Share of Voice versus visibility score
Mentionable tracks both metrics, and they tell you different things.
Visibility score is absolute. "You appear on 60% of your tracked prompts." This tells you how often LLMs mention your brand.
Share of Voice is relative. "You capture 25% of all AI recommendations in your niche." This tells you how you compare to competitors.
Both matter. A 60% visibility score with 50% Share of Voice means you're the dominant player. A 60% visibility score with 15% Share of Voice means you're one of many, and competitors collectively capture far more recommendations than you do.
The gap between your visibility score and your Share of Voice reveals how crowded your niche is in AI recommendations.
Who benefits most from Share of Voice analytics
Solopreneurs competing against larger brands need to know their position in context. A 30% visibility score might feel low, but if the largest competitor in your niche only has 35%, you're closer than you think. Share of Voice turns abstract visibility numbers into competitive positioning.
Consultants reporting to clients get a powerful metric for demonstrating progress. "Your Share of Voice grew from 12% to 22% this quarter" is a clearer success story than "you gained mentions on 4 new prompts."
Agencies managing competitive niches can use Share of Voice to benchmark client performance against competitors and set realistic growth targets based on the competitive landscape.
