Historical Measurement Record

This is an evergreen benchmark URL. New measurements are added to the same report.

Evidence and Source Layer

The benchmark is built from prompt-level observations that retain the query, AI/search surface, answer, brand outcome, recommendation placement, sentiment, and, where exposed, citations or attributable evidence sources. Source presence is evidence about the information environment. It is not automatically proof that the source caused the recommendation.

Scope Boundaries

This public benchmark does not measure:

• Market share or revenue attribution
• Attributable sales or client conversions
• Every possible AI response, only the sampled surfaces and prompts
• Organic-search ranking positions
• Social media mention volume
• Private or sponsored channels such as gated content or paid placements
• Causality from a metric movement alone; the benchmark records change, not its cause
