About the research

Each market was measured separately using market-specific questions across the buyer journey. Data was collected between 5–9 October 2026 using English-language prompts targeting the US geography across Google AI Overviews, ChatGPT and Perplexity. Results from repeated runs were pooled; citations and brand mentions were calculated separately. Missing responses were excluded, and comparisons include only engines with measurements for both companies.

In total, 60 questions across 6 markets were run (360 questions), producing approximately 1,900 responses and identifying 1,852 companies. The “who leads where” prompts shown are a subset of this research data.

All results underwent human review before publication. This is not an exhaustive market ranking. For methodology questions, or to report an issue with the data or report, please contact stefan.finch@graph.uk.
