Google and Bing measure AI search differently. Google's Generative AI performance report counts impressions in AI Overviews and AI Mode. Bing's AI Performance report counts citations. Neither tells you why a number changed. Entries here say what each report measures, in the platforms' own words, and where the limits are.
