How mention rate, branded controls, unbranded discovery, average position, and top-three presence reveal different kinds of brand visibility.
Mention Rate records brand presence
Mention Rate is the share of eligible observations in which a brand appears. It is easy to communicate, but it should be calculated by engine, theme, prompt category, and time because aggregation can hide strong and weak contexts.
Branded Recognition is a controlled recognition test
When the prompt names the brand, the engine is not discovering it independently. Branded Recognition Rate asks whether the system correctly recognizes and discusses the supplied entity.
Unbranded Discovery tests category emergence
Unbranded Discovery Rate measures whether the brand appears in relevant category, problem, use-case, or comparison prompts without being named. This is usually the more demanding visibility test and should never be averaged indiscriminately with branded prompts.
Position and Top-3 Presence measure early exposure
Average Mention Position describes ordinal placement when a brand is present. Top-3 Presence reports the share of relevant observations in which it appears among the first three options. Report both beside overall Mention Rate so absence is not hidden by a strong conditional average.
Recognition answers “Do you know us?” Discovery answers “Would you surface us?”
Questions about this topic
What is Brand Mention Rate?+
The proportion of eligible observations in which a resolved brand entity appears in the generated answer.
Why separate branded and unbranded prompts?+
A named prompt supplies the entity, while an unbranded prompt tests whether the engine independently associates it with the need.
Should average position include absent observations?+
Usually position is conditional on mention, so Mention Rate or Top-3 Presence must be shown beside it to represent absence.
Why track Top-3 Presence?+
It captures whether the brand receives early shortlist exposure rather than merely appearing somewhere in a long answer.
