Google expands AI Mode ads and starts showing them in follow-up questions

Google will show ads in AI Mode in more than ten new countries, in English for now. At the same time, it launched multiturn ads in the United States, which can appear in follow-up questions within the same conversation. The news was posted on November 9 on the official Google Ads account on X.

According to Search Engine Journal, in a story published on November 10, the announcement followed a LinkedIn post by Dan Taylor that had already pointed to plans to bring the ads to other countries in the fourth quarter. Eligible campaigns can already take part.

Brazil is next in line

Google also announced plans to bring AI Mode ads to Brazil, Mexico and the United Kingdom in the fourth quarter of 2026. Those three markets are listed as coming next, outside the first wave. In Pakistan, according to the availability documentation, only text ads are available. For multiturn ads, there is no date for expansion beyond the United States.

How the ad enters the conversation

Google describes AI Mode as a search experience for exploratory questions, reasoning or complex comparisons, where the user asks a detailed question and follows up with more. To build the answer, the system can fire off related searches across subtopics and different data sources.

With the multiturn format, an ad can show up in those follow-up exchanges when the conversation has commercial relevance. According to the advertiser documentation, the ad can match the question itself or the context of the question and the AI's response. That means an exploratory question can open the door to an ad even when nobody is searching for a specific product.

Taylor noted that people ask longer, more detailed and more exploratory questions in AI Mode, and described many of them as top-of-funnel queries with commercial intent. The story cautions that a long question, or one more follow-up, does not on its own signal that someone is ready to buy.

No separate reporting

Google's reporting documentation confirms that AI Mode impressions, clicks, conversions and costs flow into the campaign's standard report. Search terms are also lumped in with the rest of the traffic, which makes it impossible to calculate CPA or ROAS for AI Mode alone. Those terms may approximate the user's intent without reproducing the exact question.

In the view of the story's author, the most important thing right now is to be clear that reporting is limited. A campaign can improve overall while AI Mode performs poorly, or the other way around, and the blended numbers will not show it. If results shift after the expansion, the timing alone does not prove that AI Mode was the cause.

For brand teams, the takeaway is about expectations: you can review search terms for relevance, compare conversions and check lead quality, but you cannot say how much of your budget or conversions came from AI Mode until Google offers a separate view. With Brazil on the list for the fourth quarter of 2026, that limitation is set to arrive alongside the ads.
