Google AI Overviews Cut Clicks Nearly 40%; Publisher Pay Lags

Two developments are now converging. Researchers have produced some of the strongest evidence yet that Google's AI-generated answers are draining traffic from the open web. At the same time, Google has confirmed it is quietly paying a small group of publishers whose content feeds those answers. Read together, the two stories suggest the compensation on offer is nowhere near the scale of what is being lost.

The causal evidence arrives

Much of the debate over AI Overviews has relied on before-and-after traffic comparisons, which are easy to dispute. A new paper by Saharsh Agarwal of the Indian School of Business and Ananya Sen of Carnegie Mellon's Heinz College takes a different approach. The researchers built a browser extension and used it to randomly assign 1,065 desktop Chrome users to either see or not see Google's AI summaries 4. Because exposure was randomized, the authors argue they can isolate cause rather than correlation. They describe the result as the first causal evidence that AI Overviews divert clicks from publishers without improving users' search experience 4.

The headline finding: when an AI Overview appeared, outbound organic clicks dropped 39.8% and zero-click searches rose 34.5% 34.

That result lines up with larger observational work. Pew Research Center examined nearly 69,000 searches by 900 U.S. adults. Users clicked a traditional result on 8% of visits when an AI summary was present, versus 15% when it wasn't 3. Links inside the summaries drew clicks only 1% of the time 3. Ahrefs, analyzing 300,000 keywords, estimated that an AI Overview cut click-through to the top organic result by 58%, with declines of 51% and 46% for the second and third positions 3. Three methods and three scales point in the same direction, which makes the conclusion hard to wave away.

Google's answer: an opaque pilot

Against this backdrop, Google has been running what it calls an "AI contribution" pilot. It pays publishers when their content is judged to have meaningfully helped build answers in AI Overviews, AI Mode and Gemini 12. Google confirmed the program to Digiday, calling it an early-stage experiment in rewarding good content 2.

Reports differ on the program's size. The Information, as relayed by Android Headlines, put participation at roughly 100 invited publishers over the past year 1. Digiday said only that at least dozens had been approached and could not confirm a figure 2. The program also appears to have been hiding in plain sight. Search Engine Land noticed an AI contribution report in Search Console in April but didn't realize it reflected payments, and Google declined to explain it at the time 2.

The mechanics are thin on transparency. Participants see a monthly earnings number in a Search Console panel, with some history but no breakdown of how it was calculated, and they can opt out whenever they like 2.

"Peanuts" for most

The money is where the criticism concentrates. According to Android Headlines, payouts range from more than $1 million a year for certain niche sites to less than 0.1% of ad revenue for small blogs 1. A publishing executive who reviewed Google's offer told Digiday the figures were too small to justify joining 2. Smaller and mid-sized publishers have reportedly found the deal more attractive than large ones 2. That pattern is consistent with the pilot being most appealing to outlets with the least negotiating leverage.

Industry watchers frame it more charitably. Yext called it the first concrete monetization path for publishers whose work fuels AI search 5. That is true as far as it goes. A path is not the same as parity.

Why the timing matters

Google is expanding AI answers even as it tests compensation. It has begun dynamically expanding AI Overviews into fuller AI Mode-style responses by default, testing text link ads inside AI Mode, and rolling out an "info monitoring" feature that re-checks information on users' behalf 5. Each of these steps keeps users on Google longer and pushes organic links further down. The pilot is also unfolding as legal and regulatory scrutiny of Google's AI search grows in the UK and EU 1.

The takeaway

The reasonable reading is that this pilot is a pressure valve more than a remedy. The research now shows a sizable, causally demonstrated loss of clicks, and Google's own product roadmap points toward more AI answers, not fewer. A payment scheme that is invitation-only, unexplained in its math and modest for most participants doesn't close that gap. It may, however, give Google a talking point with regulators. Whether it grows into a genuine revenue-sharing model will likely depend less on Google's goodwill than on what authorities in Europe and Britain decide to require.
