AI search is draining ad inventory from premium news sites, Ozone data shows

AI search is draining ad inventory from premium news sites. Ad request volumes fell up to 41% year over year in Q2 2026, according to Ozone data reported by Digiday on July 15.

The numbers

The data covers roughly 20 billion impressions across Ozone’s premium news publisher members, including the Guardian, News UK and Dow Jones, in the US and UK only.

• US ad requests fell 32% to 37% year over year
• UK ad requests fell 39% to 41%
• Across the first half of 2026, programmatic spend in that cohort fell 30.6%, with the US down 44% and the UK down 14.3%

The mechanism is the one publishers have warned about since AI answers started appearing above links: when search engines answer questions directly, fewer people click through to the sites that produced the underlying journalism, and fewer visits mean fewer ad slots to sell.

The detail most coverage skips

Revenue fell far less than volume, because CPMs rose as inventory got scarce. Fewer ad slots, each worth more. That cushions the blow for now, but it is a strange kind of comfort: pricing power built on shrinking supply is not the same thing as a growing business.

Two caveats to keep this fair

Ozone is publisher-owned, so it is not a neutral party in this debate. And premium news is the segment most exposed to search referral traffic in the first place, which means these numbers likely represent the sharp end of the trend rather than the average across the web.

Even with those caveats, the direction is hard to argue with. The ad-supported open web was built on search sending readers to pages. If search stops sending traffic, the question every publisher and creator now faces is what replaces it.
