The **Share KPIs** measure how much of the overall visibility captured in LLM answers belongs to a specific brand or domain. They add a competitive perspective to your visibility analysis: rather than only showing whether you are present, they show **how much of the visible space you capture relative to others**. There are three Share KPIs in Search module: * **Share of Mentions** — measures a brand’s share of all brand mentions. * **Share of Citations** — measures a domain’s share of all citations (source-type domains). * **Share of Domain Presence** — measures a domain’s share of all link presence (link-type domains). Together, they help answer a key question: **when brands and domains appear in LLM answers, how much of that visibility is yours?** ## How the KPIs are calculated Each Share KPI compares the visibility generated by a brand or domain with the total visibility generated by all brands or domains within the selected scope. For example, if your brand receives 200 mentions out of 1,000 brand mentions, its Share of Mentions is **20%**. The calculation follows the filters applied to your analysis, allowing you to compare Share across specific engines, topics, periods, or other dimensions. ## How to read these KPIs The Share KPIs are a **competitive visibility signal**. * A **high Share** means the brand or domain captures a large proportion of the total mentions, citations, or domain presence in the analyzed landscape. * A **low Share** means other brands or domains capture most of that visibility. Share does not indicate how consistently a brand or domain appears across prompts, but how much of the total visibility it captures relative to others. ## How this group of KPIs fits with other signals Share KPIs are most useful when combined with other visibility signals, as each answers a different question: * **Presence Rate** measures **coverage** — how consistently you appear across the prompts and topics you track. * **Share** measures **competitive position** — how much of the total visibility you capture relative to other brands or domains. * **Visibility Score** measures **prominence** — how visible you are within generative answers, taking your position into account. * **Sentiment Score** measures **perception** — whether your brand is mentioned positively, neutrally, or negatively. In particular, **Share and Presence Rate should be read together**. A high Share does not necessarily mean broad coverage: you may dominate the results where you appear while being absent from many other prompts or topics. Conversely, you may have strong coverage but a lower Share if competitors capture more mentions, citations, or links. Combining these signals gives you a more complete picture: **where you appear, how much of the competitive space you capture, how prominently you appear, and how your brand is perceived.** **No single KPI tells the full story.** Share measures your relative weight within the results, but does not account for coverage, prominence, or sentiment. Use it alongside Presence Rate, Visibility Score, and Sentiment Score to understand the full picture of your visibility in generative answers. ## What's next The prominence companion KPI. The framing companion KPI. The coverage companion KPI.
