Key points
- Google is bringing ads in AI Mode to more than 10 new countries, English only, with Brazil, Mexico and the United Kingdom listed for Q4 2026.
- Multiturn ads, which show on follow-up questions inside an AI Mode conversation, are launching in the U.S. only; no timing given for other markets.
- AI Mode impressions, clicks, conversions and costs sit inside standard campaign reports, with no separate AI Mode view or search term breakdown.
- Google's documentation says reported search terms may only approximate what the user actually typed in AI Mode.
Why it matters for marketers: Spend on AI Mode is growing, but marketers cannot isolate its CPA or ROAS, so client reports must rely on campaign totals and lead quality checks.
Google is rolling out ads in AI Mode to more than 10 additional countries, in English, and launching multiturn ads in the U.S. The company shared the update on November 9 through its Google Ads X account. Brazil, Mexico and the United Kingdom are listed as coming in Q4 2026, separate from the initial rollout. Google's availability documentation says Pakistan supports text ads only.
Multiturn ads let Google place an ad during follow-up questions in an AI Mode conversation when the exchange has commercial relevance. Per Google's advertiser documentation, an ad can match the query itself or draw on context from the question and the AI response. Google has not said when multiturn placements will reach markets outside the U.S.
For marketers, the catch is measurement. Google's documentation says AI Mode results are folded into regular campaign reporting, and search terms are blended with other traffic. That rules out an AI Mode-specific CPA or ROAS. Search terms may also approximate user intent rather than show the exact question. Dan Taylor of Google has described many AI Mode interactions as upper-funnel queries with commercial intent, so a longer conversation does not by itself signal readiness to buy.
Eligible campaigns can already take part. Teams can still review search terms for relevance, compare conversion performance and check lead quality. Timing alone will not prove AI Mode caused a change, so agencies should tell clients plainly that overall totals can hide a split between AI Mode and other placements. Watch for any separate reporting from Google and for a wider multiturn rollout.
