TLDR;
Google has expanded ads inside AI Mode to ten more countries and launched ads on follow-up questions in the US. Existing eligible Search, Shopping and Performance Max campaigns can enter these auctions automatically, but advertisers cannot target or exclude AI Mode separately and reporting stays mixed into standard campaign data. Brands gain more conversational-search reach, but need stronger feed, conversion and creative controls because Google decides when the placement appears and may generate the explanation around it.
What happened
Google's 28 October announcement adds Australia, Canada, India, Kenya, Malaysia, New Zealand, Nigeria, Pakistan, the Philippines and Singapore to the markets where ads can appear inside AI Mode. Brazil, Mexico and the UK are planned for the fourth quarter, so they should not be treated as live yet. The new markets are English-only, and Pakistan is limited to text ads.
The US change is different. Google has launched multi-turn ads that can appear after a shopper asks a follow-up question, not only after the opening prompt. A Google spokesperson told Search Engine Roundtable that these placements show on responses to follow-up queries as a user continues the conversation. Google has not said that multi-turn delivery is live in the ten new markets.
Google Ads documentation says eligible Search, Shopping and Performance Max campaigns are automatically considered. Broad match, AI Max, Shopping and Performance Max can use both the user's prompt and the surrounding AI response as context. Exact and phrase match still depend on direct intent in the prompt. Advertisers cannot create an AI Mode-only campaign, set a separate budget or opt out of the placement alone.
The same documentation says AI Mode activity is aggregated into existing campaign and search-term reports. Gemini can add an AI-generated explainer around sponsored products, and advertisers cannot write, edit, approve or disable that explainer. Google says sponsored and organic product-list click-through rates are similar, but that is an internal US comparison from a short August-to-September period with no disclosed rate.
Why it matters
Conversational inventory changes the unit of intent. A follow-up such as 'make it waterproof and under £150' can be more commercially useful than the opening request, but the advertiser may not see which part of the conversation created the match. That makes familiar keyword reports less complete as an explanation of why an ad appeared.
The rollout also increases the distance between brand-approved creative and what a user sees. Product feed fields, landing-page content and campaign assets may be interpreted alongside an AI response, then framed by a Google-generated explainer. A clean feed and accurate page are therefore creative inputs, not merely catalogue plumbing.
The reporting limitation is the largest commercial constraint. Without an AI Mode placement breakout, a stronger campaign result cannot prove that conversational ads caused it, and a weaker result cannot be isolated quickly. Country expansion may also change the traffic mix inside a campaign before a brand has market-specific baselines.
Google's internal click-through claim is useful directional evidence, not an independent effectiveness result. Similar click-through rates do not show equal conversion, margin or incrementality, and they say nothing about performance across the new markets. Enterprise teams should treat the launch as additional eligible inventory, not as proof of a new high-performing channel.
How your brand can benefit / be affected
First, map which campaigns can enter AI Mode in each market and check that language, inventory, shipping and returns information are correct. Keep Brazil, Mexico and the UK on a readiness list until Google confirms they are live. For Pakistan, plan around text-only eligibility rather than assuming the full Shopping format.
Second, tighten feed and landing-page governance. Validate titles, attributes, prices, availability and destination URLs, then review the effect of AI Max, broad match and final URL expansion separately. If a regulated or legally sensitive claim must stay exact, do not assume a generated explainer will preserve your preferred wording.
Third, use first-party conversion data and market-level experiments. Compare eligible and ineligible geographies, watch assisted conversions and new-customer rate, and annotate the rollout date in reporting. Because Google does not provide a dedicated AI Mode performance view, these controls will not create perfect attribution, but they can stop a blended report from being mistaken for causal proof.
Finally, define an escalation path for unsuitable matches or generated context. Negative keywords, brand exclusions and feed corrections still matter, but there is no placement-specific off switch. The opportunity is meaningful reach at a later, richer stage of consideration. The cost is accepting less control over where the ad enters the conversation and less certainty about how it performed.
