Your Buyers Moved Into the Assistant, and Your Dashboard Can't See Them
Demandbase says monthly ChatGPT referrals to B2B websites grew 303 percent in a year, from roughly 645,000 to 2.6 million visits. Sundar Pichai said Gemini passed 1 billion monthly active users.
Demandbase counted the referrals this month, and the curve is the story. Monthly visits to B2B websites arriving from ChatGPT grew from roughly 645,000 to 2.6 million in a year, a 303 percent rise, with a sharp inflection in May. The figures are the vendor's own and deserve that label. The direction doesn't need the label at all.
The channel behind that curve just became two channels. Sundar Pichai said this week that Gemini passed 1 billion monthly active users, the fastest climb to that mark in Google's history, and The Verge noted that ChatGPT and Gemini now sit above a billion each. For B2B, that is most of the buying population researching through two interfaces that sell no bids, expose no keyword report, and offer no test harness. Demandbase's data adds the uncomfortable detail: nearly all measurable AI referral volume comes from one of the two. Concentration, not diversification, is the current shape of the shift.
GEO agencies and an authority index arrive
An industry is already forming around the gap. Several agencies launched dedicated generative engine optimization practices this week, positioning GEO as a discipline rather than an SEO add-on. The figures they cite, per The Drum: AI Overviews now touch around 15 percent of queries, and 30 to 40 percent of informational queries resolve without a click. Those numbers are the sales pitch of people selling the cure, and they should be discounted accordingly. The launches themselves are the harder evidence. Agencies don't spin up practices for problems their clients haven't started paying to solve.
The measurement layer arrived in the same news cycle, right on schedule. Informa TechTarget launched a B2B AI Authority Index, a diagnostic scoring how often a brand gets cited across AI-mediated purchase journeys, alongside its claim that 94 percent of B2B buyers now bring AI tools into research. The pattern is familiar from every prior platform shift: the behavior moves first, the measurement products arrive about a year later, and they arrive as something a vendor sells you, scored against your competitors, on a methodology you don't control.
USA Today's numbers show where value migrates
Publishers are running the endgame of this movie a reel ahead of everyone else. Digiday reports USA Today's digital advertising revenue down 9.2 percent year over year while digital subscription revenue rose 6.8 percent. Two numbers moving in opposite directions at the same company is the clearest available statement of where value migrates when a search engine stops sending clicks: away from rented attention, toward owned relationships. Every B2B brand running a content program is a small publisher with the same exposure and worse instrumentation.
Dashboards measure a shrinking share of discovery
Here is the gap between the dashboard and the market. Most demand teams still report a funnel built on sessions, rankings, and attributed clicks, and every one of those metrics measures a shrinking share of how buyers actually discover vendors. The team can hit every number on the dashboard while the category's real discovery surface, the answer inside the assistant, goes unmeasured and unmanaged. This is instrumentation aimed at the wrong decade, not a failure of effort.
The strategic risk is not the shift itself but the bet most teams will make in response, because it is the same bet everyone made in 2009. Building a discovery strategy on one assistant's referral behavior is building on Google all over again, except this time there is no rank to hold, no algorithm update blog to read, and no console to appeal to. The publishers gutted by the click-through decline made exactly that bet and held it for fifteen years. Their pivot to subscriptions is what survivors do after the platform stops paying, not a strategy tip.
The loudest numbers here come from vendors with something to sell: Demandbase sells the measurement of the fear, the GEO agencies sell the treatment, and Informa TechTarget sells the scoreboard. And 2.6 million monthly visits across all B2B sites is still small against search's volume. Both objections are fair, and neither is comforting. Discount every vendor figure by half and the direction survives, and the smallness is the point: this is what a channel looks like early, when position is cheap. It was also the argument for ignoring Google in 2004.
The click was the unit of a rented channel, and the rent is ending
Publishers hit this wall first, and USA Today's numbers show where the revenue went: digital advertising down 9.2 percent, digital subscriptions up 6.8 percent. B2B content teams carry the same exposure through dashboards still built on sessions, rankings and attributed clicks.
The B2B curve is earlier on the same path. Demandbase counted 2.6 million monthly visits from ChatGPT to B2B sites, up from 645,000 a year earlier, with nearly all measurable AI referral volume coming from one of the two assistants.
