AI visibility research

Prominara runs its own panel of buyer questions about public brands through ChatGPT, Perplexity, Gemini, Google AI Overviews, Google AI Mode, and publishes what the answers contain: which brands each engine names, which sites it cites as sources, and how those patterns change over time and when an engine switches to a new model.

Every study asks each question several times and in more than one wording, because the same question rarely gets the same answer twice. Each figure comes with its sample size and a 95% interval, so a difference smaller than the noise is reported as such. Releases list the full question set, the model versions the engines reported while the data was collected, and how answers were scored, including how often our extraction agreed with a human check.

Releases are frozen when published and never edited afterwards; corrections appear as a new version. The data behind each release can be downloaded as CSV and reused under CC BY 4.0 with attribution. The measurement approach is described on the methodology page.
