  60 "<brand> reviews" searches (10 per industry).
- 26 Sep 2026: the organic top 10, the AI Overview and the AI Mode answer for every search.
- 2026-09-28 to 2026-10-12, once a day at 13:00 UTC (15 runs): the AI Overview again, for every search that

  product pages, flights); they are kept, and reported separately.
