Google adds ads to AI follow-up queries as publisher traffic drops 61%

Why conversational search broke Google's ad engine

Google's AI tools answer questions so quickly that users stopped clicking on the classic search ads that generate the company's core profits.

During Alphabet's third-quarter 2026 earnings call, Chief Business Officer Philipp Schindler pointed out an uncomfortable paradox: overall search query growth reached its highest pace in five years, yet search ad revenue growth slowed down. The culprit is the shift toward AI Overviews and conversational AI Mode, experiences that currently suffer from lower monetization.

In the traditional layout, a search engine serves ten blue links bracketed by prominent text ads. When a synthetic summary answers the question right at the top of the screen, the user simply leaves. That behaviour has created a zero-click crisis for web publications, but it is now squeezing Google's bottom line as well.

Enter 'multiturn ads' inside follow-up queries

Google's response is an ad format called multiturn ads, currently launching in the United States. Rather than restricting commercial placements to the initial keyword search, Google will now inject sponsored links directly into back-and-forth conversational follow-ups.

If someone asks AI Mode how a smart appliance works and subsequently asks for recommendations or prices, the follow-up response will display sponsored product listings. Google argues that conversational search gives its system a better understanding of purchase intent as users refine their research. The aggressive push into commercialisation mirrors how other Alphabet properties squeeze monetization into every corner, much like how YouTube free tier ads worsened to protect operating margins.

Beyond the US, Google is expanding standard AI Mode ads to 10 additional countries, including Canada, Australia, Singapore, India, and Kenya, with launches in the UK, Mexico, and Brazil slated for later this year.

A tighter squeeze on open web traffic

While Google solves its revenue lag, digital publishers are left with the consequences. Industry data shows AI Overviews now show up on nearly half of all search queries, contributing to an estimated 61% plunge in raw referral volume to outside websites.

Until now, the remaining hope for publishers was that users looking for nuance would scroll down to traditional organic results. By occupying follow-up conversational answers with paid product modules, Google is effectively keeping users trapped in its own interface. SEO analyst Lily Ray warned that users looking for direct editorial coverage will increasingly need to bypass Google's defaults entirely, either by relying on search web filters or bookmarking preferred newsrooms directly.

Availability and rollout timeline

Multiturn ads in AI Mode follow-up queries are currently live for commercial searches in the US. Standard ad placements within AI Mode are expanding across 10 global markets including Canada and Australia, with rollouts in the UK scheduled before the end of 2026.

Google's aggressive move to monetise conversational search confirms that AI Overviews are not a temporary experiment. As sponsored blocks take over conversational prompts, the open web will have to fight harder than ever to stay visible.
