Google AI search advertising now includes multiturn ads in U.S. AI Mode, allowing sponsored results to appear during follow-up questions. Announced October 28, 2026, the expansion gives eligible advertisers additional placements without requiring separate campaigns or budgets. The update also raises questions about keyword targeting, campaign controls and performance measurement.
Key Takeaways
- Google launched multiturn ads in U.S. AI Mode on October 28, 2026, extending advertising to follow-up search queries
- Existing eligible Search, Shopping and Performance Max campaigns can participate through standard ad auctions
- Broad-match and AI-powered targeting can qualify for contextual placements, while exact and phrase match have narrower eligibility
- Google combines AI Mode advertising metrics with standard campaign reports, limiting placement-specific measurement
Google is extending its search advertising system into longer AI-powered conversations, allowing businesses to reach users beyond their initial questions. The newly announced multiturn format adds sponsored placements to follow-up exchanges in AI Mode, where users can refine searches, compare products and explore related information without starting a separate query.
The October 28 announcement came from Shashi Thakur, Google’s vice president and general manager for Search Ads and Ads on Google Experiences. It builds on the company’s earlier introduction of advertising within AI-generated search results.
A Google spokesperson told Search Engine Roundtable, “Multiturn ads show up on responses to follow-up user queries as users engage in back and forth conversations with AI Mode.”
The development expands the circumstances in which existing advertising campaigns may appear. However, Google has not released separate conversion benchmarks for multiturn ads or introduced dedicated reporting that would allow advertisers to isolate their performance.
Google Expands Advertising Beyond the First Search Query
Google’s AI Mode allows users to continue a search through connected questions rather than entering an entirely new request each time. A conversation may begin with general product research before moving into comparisons, specifications or purchasing considerations.
Under the multiturn format, Google can display relevant sponsored results during those later exchanges when its systems identify commercial relevance. The advertisements may appear within or alongside AI-generated responses and must remain clearly labeled as “Sponsored.”
Google illustrates the approach with a search about cleaning a swimming pool that has turned green. Although the initial question concerns maintenance, an AI-generated explanation might discuss equipment or cleaning products. Relevant advertisements for those products could then appear alongside the response.
The company distinguishes this contextual approach from traditional keyword matching, where advertisements respond more directly to an expressed search term. Google says AI Mode queries average three times the length of traditional searches, citing a U.S. report from May 2026.
That comparison describes how users formulate queries, rather than establishing that longer searches generate more purchases. Google has also stated that paid advertising does not influence the organic answers produced by its AI search systems.
Alongside the U.S. multiturn launch, Google announced plans to scale AI Mode advertising in ten additional countries, including Canada, Australia, India, Malaysia and the Philippines. Brazil, Mexico and the United Kingdom were identified among markets planned for expansion during the fourth quarter of 2026. The multiturn format itself was announced specifically for the United States.
Existing Google Ads Campaigns Gain New Placement Opportunities
The expansion does not require businesses to establish a separate advertising account or campaign. According to Google’s published guidance, existing eligible Search, Shopping and Performance Max campaigns can automatically participate in AI Mode advertising through the company’s standard auction system.
However, eligibility depends partly on the targeting methods already used within those campaigns.
Google says AI Max for Search, broad-match keywords, Shopping campaigns and Performance Max can qualify for both direct query matching and contextual matching. Exact-match and phrase-match keywords remain eligible when users express direct commercial intent, but they do not qualify for contextual placements based on broader exploratory questions.
For example, a user searching directly for pool-cleaning equipment may trigger a relevant exact-match advertisement. A broader question about solving a maintenance problem could instead create contextual advertising opportunities for campaigns using eligible AI-powered targeting.
The difference gives keyword settings a more specific role in determining which campaigns can enter the auction. Google has not announced separate fees for these placements, and existing cost-per-click or conversion-based bidding arrangements continue to apply.
Google also uses advertisers’ existing creative assets, including headlines, descriptions, images, prices and landing pages. In some placements, its Gemini models can generate short explanations describing how sponsored options relate to the user’s search.

These explanations may draw on publicly available information, including an advertiser’s website. Google states that advertisers cannot individually write, edit, approve or disable them, although standard campaign controls such as negative keywords and brand exclusions remain available.
For businesses managing online product catalogs, Google recommends maintaining accurate Merchant Center information, including product descriptions, images, pricing and shipping policies.
The approach differs from AI search marketing platforms, which focus on monitoring brand visibility within AI-generated answers. Google’s multiturn format concerns paid placements selected through advertising auctions rather than organic mentions within search responses.
Limited Reporting Creates Challenges for Campaign Measurement
Although the new format extends where advertisements can appear, Google does not currently provide separate reporting for multiturn placements.
Impressions, clicks, conversions and advertising costs from AI Mode and AI Overviews are included in existing Google Ads campaign reports. Search terms associated with these experiences also appear within aggregated search-term reporting.
Consequently, advertisers cannot use standard reports to determine precisely how many conversions resulted from multiturn ads rather than other eligible search placements.
Google also does not permit advertisers to target AI Mode exclusively or exclude it independently from Search. Existing negative keywords and brand exclusions can still help determine when advertisements are eligible to appear.
Those limitations matter for marketing teams assessing campaign performance across multiple channels. Businesses increasingly using content intelligence for marketing can examine broader engagement and conversion patterns, but those tools cannot independently supply placement-level data that Google’s reporting does not distinguish.
Google has provided some internal research on engagement with advertising inside AI Mode. Data collected in the United States between August 20 and September 3, 2026, indicated that sponsored and organic product listings received similar click-through rates.
However, the company did not publish exact rates or establish that those findings apply to multiturn advertising specifically. The comparison also does not indicate whether users who clicked sponsored listings were more likely to complete purchases.
For U.S. advertisers, Google AI search advertising now includes opportunities to appear throughout relevant search conversations, while the ability to measure results from those placements separately remains limited.
