Ad supply on publisher sites dropped sharply in Q2 2026. AI-driven, zero-click search reduced open web traffic. Higher eCPMs helped offset lost ad volume, especially in the UK.
Digital publishers in the U.S. and U.K. saw their available ad supply shrink by as much as 40% in the second quarter of 2026, as AI-powered, zero-click search tools sharply reduced traffic to news and open web sites. This shift has immediate consequences for media businesses that rely on display ad revenue and audience reach.
Benchmarking data from Ozone, covering about 20 billion impressions, showed that between April and June 2026, publisher ad request volumes fell by 32% to 37% year-over-year in the U.S. and by 39% to 41% in the U.K. The figures reflect ad opportunities tracked across Ozone’s network of premium publishers, including the Guardian, News UK, and Dow Jones’ Wall Street Journal.
Despite the steep drop in ad requests, overall ad spend did not decline at the same rate. Rising effective cost per thousand impressions (eCPMs), especially in the U.K., helped offset some of the lost volume, according to Ozone’s data. This suggests that while publishers are seeing fewer ad opportunities, the value of each impression has increased, partially cushioning the revenue impact.
These findings echo broader concerns about the impact of AI-driven search and changing traffic patterns on publisher monetization. For a deeper look at how AI-native advertising is evolving and reshaping the media landscape, see this analysis of OpenAI and Google’s recent moves in AI media.
