The pages AI reads before it names a vendor

We asked ChatGPT, Claude, Perplexity, Google AI Overviews and Google AI Mode ten buyer questions in each of 14 software categories, three runs each, and recorded 150 answers per category in September 2026. These are the pages those answers cited most, what each page is, and which Index vendors it lists. Observed answers on stated dates, not a ranking.
