Answer in brief

Benchmark AI visibility by fixing the eligible prompt set, answer engines, geographies, personas, and observation window. Compare mention share, citation share, cited pages, and position only within that declared cohort. A competitor score from a different prompt market or model mix is not a valid benchmark.

Define the competitive question

A category benchmark asks who appears for non-branded discovery prompts. A head-to-head benchmark asks how brands compare in explicit evaluation prompts. A reputation benchmark asks which attributes accompany each mention. Mixing them can reward a brand for appearing in a different market than the one being evaluated.

Tag prompts by intent and keep the eligible set visible. The denominator should include every eligible answer, not only the answers in which one of the tracked brands appeared.

Control the model and market mix

Answer engines can produce different brand sets and source patterns for the same question. Report each model separately, then publish a blended view only if the weights are documented and relevant to the decision.

Country, language, persona, and location can change recommendations. Compare brands within the same configuration and preserve runs where a product returned no usable answer.

Move beyond one share-of-voice number

Mention share answers who appears. Citation share answers whose pages or supporting sources receive visible links. Position, sentiment, attributes, and source overlap add different evidence. None should silently substitute for another.

At page level, identify where competitors are cited, which source types carry their mentions, and where your owned pages already participate. These differences reveal opportunities that a single rank conceals.

Treat change as a time series

Run the same cohort on a schedule and use several observations before declaring a durable gain. Label prompt additions, model changes, entity-resolution fixes, and partial periods because each can move the benchmark without a market change.

A useful executive view pairs the competitive movement with the work completed and the remaining uncertainty. That keeps the benchmark connected to decisions rather than theater.

Methodology note

The framework treats every benchmark as a cohort comparison. It does not provide a universal industry average. Missing answers, model availability, prompt variations, and entity resolution should be documented before calculating competitive shares.
