Key details

  1. Google announced expansion October 28, 2026 to 10 countries including New Zealand.
  2. Brazil, Mexico and the United Kingdom are planned for Q4, not necessarily live today.
  3. US multiturn ads can appear on follow-up queries within AI Mode.
  4. Eligible existing Search, Shopping and Performance Max campaigns automatically participate.
  5. Advertisers cannot separately target or opt out of AI Mode placements.
  6. Reporting is aggregated into standard campaign and search-term reports.
  7. English is the listed language for in-answer AI Mode ads; Pakistan currently text ads only.
  8. Google's CTR comparison is internal research, not independent ROI evidence.

What builders should take away

  1. Check whether your current Search, Shopping and Performance Max campaigns are eligible in the new markets.
  2. Do not assume AI Mode requires a new campaign or budget, or that it can be disabled separately.
  3. Audit Merchant Center product data and landing-page accuracy for conversational shopping queries.
  4. Use first-party conversion measurement and compare results over time, while acknowledging no placement-level AI Mode breakout.
  5. Treat Google's click-through-rate claim as vendor data, not a guarantee of conversions.

What changed

On October 28, 2026, Google announced that ads in AI Mode are scaling to Australia, Canada, India, Kenya, Malaysia, New Zealand, Nigeria, Pakistan, the Philippines and Singapore, with Brazil, Mexico and the UK planned for later in Q4. Google also launched ads in follow-up queries within AI Mode in the United States. Its Ads Help documentation confirms that existing eligible Search, Shopping and Performance Max campaigns can automatically enter AI Mode auctions, with no separate budget or campaign requirement. Advertisers cannot target AI Mode alone or exclude it separately from Search; performance is included in existing campaign and search-term reports rather than a dedicated AI Mode breakout. Google says sponsored and organic product-list click-through rates in AI Mode are similar, but that comparison uses internal US data and should not be treated as independent evidence of performance.

Why it matters

This changes the reach and measurement of paid search for businesses outside the US, including New Zealand advertisers. Campaigns may begin serving inside conversational answers without a separate opt-in, and US ads can now appear after follow-up questions where purchase intent emerges. However, the lack of separate AI Mode targeting, opt-out and granular reporting makes it harder to evaluate incrementality, creative performance or costs independently. Businesses should monitor campaign results and landing-page accuracy rather than assume AI Mode placements outperform traditional search.

Ten new markets and US follow-up conversations

Google's October 28 announcement names Australia, Canada, India, Kenya, Malaysia, New Zealand, Nigeria, Pakistan, the Philippines and Singapore for expansion. It plans Brazil, Mexico and the UK during Q4 2026. In the US, multiturn ads can show on follow-up questions inside AI Mode. The rollout is ongoing; country and language eligibility may vary, and the current Google Ads Help list restricts AI Mode and in-answer AI Overview ads to English.

Existing campaigns enter without a new AI Mode budget

Google Ads Help says eligible Search, Shopping and Performance Max campaigns automatically participate when relevant. Text and Shopping ads are supported; other formats are being tested. Standard Google Ads auction, CPC or conversion bidding and negative-keyword controls apply. Advertisers cannot run an AI-Mode-only campaign or opt out of AI Mode independently from Search.

Matching depends on conversational intent

Google distinguishes direct commercial queries from exploratory conversations where the AI response creates contextual purchase intent. Broad match, AI Max, Shopping and Performance Max can be eligible for contextual matching, while exact and phrase match require direct commercial intent. This may change which queries generate ad impressions even without a new keyword list.

Measurement remains aggregated

Google says AI Mode and AI Overview impressions, clicks, conversions and cost are folded into existing campaign reports and search-term reporting. The documentation does not offer a standalone AI Mode performance breakdown. Its statement that product-ad CTR is comparable to organic product listings comes from Google internal US data collected August 20–September 3, 2026; it is not an independently replicated benchmark and does not establish advertiser ROI.

Practical response for small advertisers

Review eligibility and existing campaign settings, check negative keywords and brand exclusions, and make sure Merchant Center feeds, prices, shipping terms and landing pages are accurate. Monitor performance around the rollout and avoid attributing changes solely to AI Mode without placement-level data. Google says paid ads do not influence the organic AI response.

What to watch next

  • Completion of the 10-market rollout and planned Brazil/Mexico/UK expansion.
  • New reporting segmentation or controls for AI Mode placements.
  • Advertiser cost and conversion evidence outside Google's internal CTR study.
  • Changes to language eligibility, supported ad formats and multiturn matching.

Still unclear

  • The announcement says scaling, not that all inventory was live in every named market at once.
  • Google has not disclosed a placement-level performance report for AI Mode.
  • No independently verified conversion or ROI improvement is established.
  • The country/language list and auction formats may change during rollout.
