TL;DR
Google said on October 28 that ads in its AI Mode search experience are expanding to 10 more countries, with ads also appearing in US follow-up questions. The move comes as Google Search advertising revenue growth slowed to 12% in the third quarter; how the new formats affect publishers and users remains uncertain.
Google is expanding ads in its AI Mode search experience to 10 additional countries and adding ads to US follow-up questions, the company said October 28. The rollout extends advertising into longer, conversational searches as Alphabet reported that Google Search and other advertising revenue grew 12% in the third quarter, down from 17% in the previous quarter.
The new markets for AI Mode ads are Australia, Canada, India, Kenya, Malaysia, New Zealand, Nigeria, Pakistan, the Philippines and Singapore. Google said it plans to add Brazil, Mexico and the United Kingdom in the fourth quarter of 2026. In the United States, ads can now appear not only in an initial AI Mode response but also in answers to follow-up questions.
Google describes AI Mode as a chat-style search feature, distinct from AI Overviews, which are AI-generated summaries shown within standard search results. Ads already appear in AI Overviews in the US. The October announcement concerns the expansion of ads in AI Mode and the addition of ads to later turns in a US conversation.
According to Google Ads Help, existing Search, Shopping and Performance Max campaigns may be included automatically. Advertisers do not have a separate targeting control or opt-out for these placements, and reporting is provided in aggregate. Google also generates short ad explainers that advertisers cannot edit. The company says ads will carry a “Sponsored” label and will not shape the AI-generated answer; the latter is Google’s assertion, and the source material identifies no independent audit of it.

How Google moved ads into its AI answers in two years, where they show today, and the revenue pressure behind the move.
Where ads appear inside AI answers
Per Google’s help page and the 28 Oct post. The list “may not be exhaustive”.
Follow-up questions (“multiturn ads”): US only. Germany and the rest of the EU: not listed. Ads above or below AI Overviews can show wherever AI Overviews exist (200+ countries and territories).
Why now: Google Search & other revenue growth
Year over year, as reported by Alphabet. Bars scaled to 19%.
Q2 to Q3 2026: about +0.1%. Same months a year earlier: about +4.4% (my arithmetic). Google names exchange rates as the largest driver of the slowdown, and the “lower monetization” of AI Mode as one factor.

Ads Follow Longer Search Conversations
The expansion gives Google more opportunities to show ads within searches that may continue across several questions, rather than ending with a list of links. For advertisers, the placements extend existing campaigns into AI Mode, but the lack of a dedicated opt-out or detailed placement reporting may limit their control over where ads appear and how they assess performance.
The change also matters to publishers that depend on search referrals. A user who gets a useful answer directly on Google may have less reason to visit a website, while ads can still appear alongside the answer. A 2026 working paper by Agarwal and Sen reported that, in a randomized experiment involving 1,065 US users, AI Overviews reduced clicks to websites by 39.8% when shown; the study found no measurable change in ad clicks. That result concerns AI Overviews in the experiment, not the new AI Mode placements, and does not establish what will happen to publisher traffic as this rollout expands.
For users, the immediate practical distinction is between the answer and a paid placement. Google says ads are labeled “Sponsored,” but whether people consistently recognize the label in conversational results, and how the formats affect clicks, is not established by the announcement.

Search Revenue Meets AI Growth
Alphabet reported $63.4 billion in third-quarter revenue from Google Search and other activities, about half of Alphabet’s total revenue. The business grew 12% year over year, compared with 17% in the second quarter and 19% in the first quarter of 2026. These figures make the advertising rollout relevant to Google’s effort to earn revenue from search activity as its products change.
On Alphabet’s earnings call, chief business officer Philipp Schindler said exchange rates were the largest factor affecting Search growth. He also cited changes in spending by some retail, media and entertainment advertisers. Schindler said growth in AI Mode queries affected revenue because those searches had “lower monetization” than other search activity. That explanation is Google’s account of the quarter; the announcement does not quantify how much revenue the new ad placements may generate.
Google has been adding advertising to AI search in stages. Ads in AI Overviews began appearing on mobile in the US in October 2024 and expanded to desktop in May 2025, when the company also began testing ads in AI Mode. Google said in May 2026 that it was testing other formats, including conversational ad text and highlighted answers. The October expansion builds on those earlier steps.
““The strong growth in AI Mode queries had an impact because of the lower monetization we were seeing in AI mode.””
— Philipp Schindler, Alphabet chief business officer, on the company’s earnings call
Performance and User Effects Remain Open
The announcement does not state how much revenue the expanded AI Mode placements are expected to bring in, how many users will see them, or whether the rollout will change click-through rates or publisher referrals. Google cited internal US data from August 20 to September 3, 2026, saying click-through rates were similar for sponsored and unpaid product-list items within AI Mode. That comparison concerns product listings inside AI Mode; it is not a measure of clicks to publisher websites or a forecast for the newly added countries.
The company says ads do not influence AI Mode’s answers, but the source material reports no independent audit of that claim. It is also unclear how advertisers will judge performance when results are reported in aggregate and there is no separate control to opt out of these placements. Google’s Ads Help information listed 12 countries for ads inside AI answers, in English, as of October 29; Germany and other European Union countries were not listed.
Rollout and Reporting to Watch
Google plans to bring AI Mode ads to Brazil, Mexico and the UK in the fourth quarter of 2026, following the expansion announced October 28. The company has not provided a specific date for those launches in the source material. Advertisers and publishers will be watching for further details on market availability, reporting and the performance of ads shown in follow-up answers.
The next useful evidence will include results from the rollout: whether the placements draw clicks, how they affect referrals to websites, and whether Google publishes more detail about ad performance and labeling. Until those data are available, the announcement confirms a broader distribution of ads in conversational search, but not its financial impact or its effect on users and publishers.
Key Questions
Where is Google expanding ads in AI Mode?
Google said ads are expanding to Australia, Canada, India, Kenya, Malaysia, New Zealand, Nigeria, Pakistan, the Philippines and Singapore. Brazil, Mexico and the UK are planned for the fourth quarter of 2026.
What are US follow-up-question ads?
They are paid placements that can appear in answers to later questions within a US AI Mode conversation, not only in the response to the initial search.
Can advertisers opt out of these placements?
Google Ads Help says existing Search, Shopping and Performance Max campaigns can participate automatically. The source material says there is no separate opt-out or targeting control for these placements, and reporting is aggregate.
How can users identify an ad in an AI answer?
Google says ads in AI answers will be labeled “Sponsored.” Its claim that ads do not influence the AI’s answer has not been independently audited in the source material.
Does the rollout mean publisher traffic will fall?
That has not been established for the new AI Mode ads. A 2026 working paper reported fewer website clicks when AI Overviews appeared in a randomized US experiment, but those findings do not directly measure the effect of the AI Mode expansion.
