Google multiturn ads appear in US AI Mode follow-up answers

Google's multiturn ads, the format that puts Sponsored results into follow-up questions in AI Mode, are now showing in live US sessions. Testing on Friday 6 November found ads on a follow-up answer, with two Sponsored blocks at the foot of the response, and more ads on the third and fourth follow-ups in the same conversation.

Google announced the format on 28 October in the same post that named Australia among ten new countries for ads in AI Mode. Shashi Thakur, Google's VP and GM for Search Ads and Ads on Google Experiences, wrote that multiturn ads were launching in the US "to allow ads in follow-up queries in AI Mode". A Google spokesperson described them as ads that appear on responses to follow-up queries as people go back and forth with AI Mode. Google has not published a rollout schedule or said whether every US user now sees them.

Are multiturn ads now live in AI Mode?

Google announced ads in AI Mode, as a test, in May 2025. Google presents multiturn ads as the format that allows ads in follow-up queries; Google's wording implies that, before them, ads in AI Mode were tied to the opening question.

In the 6 November test, ads appeared on the first query, again on the follow-up, and then on the third and fourth follow-ups as the tester kept asking.

The follow-up question is what separates AI Mode from an AI Overview, a single summary on a normal results page, so it helps to be clear on how AI Overviews and AI Mode differ before reading your own data.

How contextual matching uses the AI response

Google's Ads Help page for AI surfaces describes two ways an ad can be matched in AI Overviews and AI Mode. When the query already carries clear commercial intent, such as "pool vacuum cleaners", Google matches ads to the query as it does on a standard results page.

When the question is exploratory, Google matches contextually to the query and the AI response together. Its example is "why is my pool green and how do I clean it?". The answer talks through water testing, brushing and vacuuming, and that lets Google serve Text or Shopping ads for pool vacuums or algae treatment kits.

Follow-ups are where contextual matching is likely to matter most. Shivani Mohan, Google's VP of Data Science and User Experience Research for Search, said on Google's Ads Decoded podcast on 28 October that people are asking much longer questions and "net new types of queries that they would have never thought to ask before". She said Google's data scientists count it against Search when a user has to add words to refine a query, and she reads the rise in follow-up questions as people exploring further, not as a sign the first answer missed. Google says AI Mode queries are on average three times longer than traditional searches.

Exact and phrase keywords skip contextual matching

The help page is specific about which targeting gets which match. Broad match, AI Max for Search, Shopping and Performance Max can be matched in either way: to the question alone, or to the question plus Google's AI answer.

Exact and phrase match keywords only qualify when the searcher's own words already show buying intent, so they miss the exploratory questions where Google reads intent from the answer. Google says queries on these surfaces are often longer, exploratory and conversational.

Existing guardrails carry over: negative keywords, asset pinning and brand exclusions all apply. Advertisers cannot target AI Mode on its own or opt out of it while staying in Search. Google treats it as part of Search, with the same auction and CPC or conversion-based bidding, and says there is no extra charge.

Advertisers cannot edit the AI explainer text

Some placements show an AI explainer, short text generated by Google's Gemini models that introduces a group of Sponsored options or adds context beside an ad, drawing on the query, the AI response and public sources including the advertiser's website. Explainers sit outside the headline and description, and advertisers cannot write, edit, approve or opt out of them.

Google's advice is to keep website content clear and current so the explainer draws accurate context. Text and Shopping ads are the formats serving today; Google says it is experimenting with local inventory ads and vehicle ads.

Multiturn ads are announced for the US only

Multiturn ads were announced for the US alone. Australia's position is the one Google set out on 28 October when it announced ads in AI Mode for Australia alongside Canada, India, Kenya, Malaysia, New Zealand, Nigeria, Pakistan, the Philippines and Singapore, with Brazil, Mexico and the United Kingdom due in Q4 2026.

The help page's availability list for ads inside AI Overviews and AI Mode runs to twelve countries, English only, with Indonesia limited to AI Overviews and Pakistan to text ads.

So an Australian advertiser's Search, Shopping and Performance Max campaigns are already eligible to serve in AI Mode answers here, and the same campaigns are eligible for follow-up ads on any US traffic they target. Google has given no date for multiturn ads outside the US.

Campaign reports show no separate AI Mode segment

There is no AI Mode segment in Google Ads. Impressions, clicks, conversions and cost from AI Overviews and AI Mode are included in aggregate in standard campaign reports, and the queries that triggered those ads sit in the search terms report with everything else.

That leaves the search terms report as the only window. Long, question-shaped terms appearing against broad match or AI Max in a US-targeted campaign are the likeliest trace of follow-ups.

Google's only published performance figure so far is that click-through rates are "already similar between sponsored and organic product list items within AI Mode", drawn from its own US data for 20 August to 3 September 2026. That measures ads against organic listings, not against ads elsewhere on Search. Alphabet's September-quarter filing gives no separate AI Mode figures for paid clicks or cost per click.

Alphabet says AI Mode monetises less

Google has a commercial reason to push ads deeper into conversations. In the September quarter, Google Search and other revenue reached US$63.35 billion, 12% more than a year earlier. Paid clicks rose 8%, slower than the 13% growth Alphabet reported in both of the year's first two quarters, and cost per click climbed 4%.

Asked why queries were growing faster than Search revenue, chief business officer Philipp Schindler named currency as the largest driver of the slowdown in Search growth from the June quarter, pointed to some industry-specific effects, and said strong growth in AI Mode queries had also weighed on revenue because of AI Mode's lower monetisation. He also said many AI Mode queries are upper-funnel and that the majority are incremental. Google says these ads run through the same auction as other Search ads, so follow-up inventory is priced like any other Search click, and overall cost per click is still rising.

Australian accounts can prepare for multiturn ads now

The same matching rules already govern first-query AI Mode ads in Australia, so the work is the same whether multiturn ads reach here next quarter or next year.

• Check whether core non-brand campaigns run exact and phrase only. If so, they are eligible for direct-intent queries in AI Mode and nothing else. Give broad match or AI Max for Search, with search term matching on, a set share of non-brand budget and judge it on its own CPA or ROAS.
• Back it with conversion-based or value-based Smart Bidding and first-party conversion data through the Google tag or offline imports, which Google says the contextual auction needs to bid well.
• In AI Max and Performance Max, switch on text customisation and final URL expansion so Google can tailor ad copy and choose landing pages for longer, question-style searches. Then check your most expensive landing pages: do they answer the comparison, sizing and pricing questions a follow-up would ask?
• For Shopping, keep Merchant Center titles, descriptions, images, prices, ratings and shipping and returns policies matching the landing page. Google's six optional conversational attributes from May (question_and_answer, document_link, related_product, item_group_title, variant_option and popularity_rank) can go in through a supplemental data source without touching the primary feed.

Campaigns that also target the US deserve a look this month. Their search terms reports may already carry follow-up queries from AI Mode conversations, and Black Friday falls on 27 November.
