Query Cluster
A group of semantically related prompts treated as a single unit for measurement, rather than tracking each prompt in isolation.
Why clustering
Individual prompt results are noisy — one prompt's wording can shift an answer in ways that have nothing to do with a brand's actual visibility. Rolling related prompts (different phrasings of the same underlying question) into a cluster and averaging results across them produces a steadier, more trustworthy signal for that topic.
How it's used
Reporting is often organized by cluster rather than by individual prompt — for example, a "pricing questions" cluster or a "alternatives to X" cluster — which makes it easier to see which topic areas a brand is strong or weak in, rather than sifting through results prompt by prompt.
