Ads in AI Mode: What Changed in October 2026 and What Advertisers Should Do

By the MarketingStackHub team · Research-based, from vendors’ own pricing pages and documentation · How we research

The short answer

Ads in AI Mode, Google’s conversational search, are spreading beyond the US. On 28 October 2026 Google said it’s scaling them in 10 more countries, adding ads to follow-up questions in the US, and planning the UK, Brazil and Mexico for Q4 2026. There’s nothing to switch on and no way to opt out: existing Search, Shopping and Performance Max campaigns take part automatically. What you control is how your targeting, search terms and landing pages handle longer, conversational searches.

What changed: 10 countries

Best for: advertisers in Australia, Canada, India, Kenya, Malaysia, New Zealand, Nigeria, Pakistan, the Philippines and Singapore, and US accounts now that follow-up questions can carry ads.

Line not to cross: assuming the UK is live; Google plans it for Q4 2026.

Check: your matching

Best for: accounts on exact and phrase match, which qualify only for searches with direct commercial intent, not for exploratory questions.

Line not to cross: switching everything to broad match to chase a placement you can’t measure on its own.

Read: matching ↓

Do: read search terms

Best for: anyone with eligible campaigns. Google says AI Mode queries are on average three times longer, and they land in your search terms report.

Line not to cross: waiting for a separate AI Mode report; results are mixed into your normal ones.

What changed in October 2026

On 28 October 2026, Google’s announcement made three changes to ads in AI Mode, the conversational version of Google Search where people ask follow-up questions:

  • 10 new countries. Google is now scaling ads in AI Mode in Australia, Canada, India, Kenya, Malaysia, New Zealand, Nigeria, Pakistan, the Philippines and Singapore.
  • Ads in follow-up questions. In the US, Google is launching what it calls multiturn ads, so ads can appear in follow-up queries, not only after the first question.
  • More countries planned. Google plans to expand to more locales in Q4 2026, including Brazil, Mexico and the United Kingdom.

The same post gives two numbers from Google’s own research: queries in AI Mode are on average three times longer than traditional searches, and click-through rates are already similar for sponsored and organic product listings within AI Mode. Both are Google’s figures about its own product, not independent measurement, but the first one is easy to check: look at how long your search terms have become.

This is the second step, not the first. Google first tested ads in AI Mode in the US in 2025, and its May 2025 announcement said advertisers using Performance Max, Shopping, and Search campaigns with broad match (including AI Max) would be eligible. Google’s help page today also lists exact and phrase match keywords, for searches with clear commercial intent.

AI Mode and AI Overviews: two placements

Google’s AI search comes in two forms, and ads behave a little differently in each. AI Overviews are the AI summaries that appear on some normal search results pages. AI Mode is a separate, chat-like mode for longer questions, comparisons and follow-ups. Google’s help page describes the range as running from quick snapshots in AI Overviews to multi-turn conversations in AI Mode.

Ads can appear inside both, and standard ads can also appear above or below an AI Overview, as they do around any other results. The October change is about ads in AI Mode specifically, plus the follow-up questions that make AI Mode a conversation. Ads in AI Overviews were already covered in our Google Ads updates 2026 checklist.

Where ads in AI Mode run now

Google’s help page on ads in AI experiences separates two kinds of placement. Its country list, which we checked on 29 October 2026, comes with a note that it may not be exhaustive:

  • Within AI Overviews and AI Mode: the United States, Australia, Canada, India, Indonesia (AI Overviews only), Kenya, Malaysia, New Zealand, Nigeria, Pakistan (text ads only), the Philippines and Singapore, in English only.
  • Above or below AI Overviews: all 200+ countries and territories, and all languages, where AI Overviews are available.

So a UK advertiser can already appear above or below an AI Overview, as on any results page, but not inside AI Mode yet: the UK is on Google’s Q4 2026 plan, not on the help page’s list. The same goes for Brazil and Mexico, and the language is English everywhere so far. If you advertise in one of the new countries, there’s nothing to turn on, but it’s a good moment to look at your search terms (below).

How ads in AI Mode are matched

Google matches ads in AI Mode in two ways, according to its help page:

  • Direct query matching: the search itself shows clear commercial intent, so ads match it as on a normal results page. Google’s example is someone searching for pool vacuum cleaners.
  • Contextual matching: someone asks a longer, exploratory question, and the ad matches both the question and the AI answer. In Google’s example, a question about why a pool has turned green leads to an answer about testing, brushing and vacuuming, and then to ads for pool vacuums or algae treatment kits.

Which of the two your campaign can use depends on its targeting:

  • Both kinds of matching: AI Max for Search campaigns, broad match keywords on Search, Shopping campaigns and Performance Max.
  • Direct matching only: exact and phrase match keywords. They qualify when the search shows direct commercial intent, but not for broader exploratory questions.

That’s the trade-off in one line. A tightly controlled account on exact and phrase match still shows for searches like “pool vacuum cleaners” in AI Mode, but not for the conversational questions that make AI Mode different. Reaching those means broad match, AI Max, Shopping or Performance Max, with the less predictable search terms that come with them. Our guide to Google Ads campaign settings explains why a new, small campaign often starts on phrase and exact match anyway, and when to test broad.

What the ads look like

Ads in AI Mode are built from your existing assets: headlines, descriptions, images, prices and landing pages. Google says text ads and Shopping ads can appear within AI Overviews and AI Mode, and it’s experimenting with local inventory ads and vehicle ads. Every ad is labeled “Sponsored” and set apart from the AI answer.

Some placements add an AI explainer: a short text written by Google’s Gemini models that introduces a group of sponsored options, or adds context next to an ad, using the search, the AI answer and public sources including your website. It isn’t part of your ad, and you can’t write, edit, approve or opt out of it. Sometimes a fixed header such as “You might consider these options” appears instead.

That matters more than it looks. Your landing pages now feed text you never see in the ad editor, and Google’s own advice is to keep your website clear and up to date so explainers have accurate context. Check the pages behind your ads as carefully as the headlines; our responsive search ads guide has a free checker for the headlines themselves.

What you can and can’t control

  • You can’t target ads only to AI Overviews or AI Mode, or opt out of them separately from Search. Google calls them core experiences within Google Search.
  • You can keep using negative keywords, brand exclusions and asset pinning; Google says existing guardrails still apply.
  • Billing is unchanged: the same auction and cost-per-click or conversion-based bidding as other Search ads, with no extra charge and the usual invalid-traffic protection.
  • Placement rule: your ad can appear above an AI Overview and inside it on the same search, but not inside it and immediately below it.

Google also says buying ads doesn’t influence what its AI writes in organic answers, and whether your site is cited organically doesn’t affect your ad eligibility.

How ads in AI Mode show in your reports

There’s no AI Mode segment. Google says results from AI Overviews and AI Mode are included in aggregate in your normal reports: impressions, clicks, conversions and cost in the campaign report, and the queries that triggered your ads in the search terms report.

So you can’t isolate ads in AI Mode, but you can look for signs of them. Longer, question-like search terms are one clue, though people type long questions on regular Search too, so treat them as a hint rather than proof. Note the date ads in AI Mode reached your country and compare campaign results before and after it.

In September 2026 Google announced a reporting view that shows the search term, the assets a person saw and the landing page in one place, with details and availability promised later this year. Until it arrives, the search terms report is the closest view; our weekly search-term triage keeps it to a few minutes with a free script.

What to do: six steps for advertisers

  1. Check your markets. Compare the countries you target with the help page’s list. In the US or one of the 10 new countries, in English, your eligible campaigns can already show; in the UK, Brazil or Mexico, plan for Q4 2026.
  2. Decide on matching, campaign by campaign. Exact and phrase keep you to commercial-intent searches. If you want contextual placements, test broad match or AI Max on one campaign in a custom experiment, with conversion-based Smart Bidding and tracking you trust, rather than switching every campaign at once.
  3. Read search terms weekly. Longer queries bring new kinds of irrelevant traffic. Add negatives for questions you can’t serve, as the five-minute search-terms block in our Google Ads checklist does.
  4. Make landing pages answer questions. Conversational searches land on your pages, and AI explainers draw on your site. Put prices, service areas and the answers to common questions in plain text.
  5. Fix your product feed if you sell online. For Shopping ads, Google asks for complete Merchant Center product data that matches your landing pages: titles, descriptions, images, prices, ratings, shipping and returns.
  6. Judge by campaign, not placement. Because AI Mode results are mixed into your reports, measure cost per conversion by campaign and date range, and keep brand exclusions and negatives in place before you widen anything.

The copy-ready checklist

Copy this into your notes and work through it once for each account that targets one of the listed countries:

ADS IN AI MODE

[ ] Markets: on Google's
    list, or Q4 2026?
[ ] Match types: exact and
    phrase only, or broad
    or AI Max too?
[ ] Conversion tracking
    works
[ ] Experiment set up
    before widening
[ ] Search terms read
    weekly
[ ] Negatives for
    questions we can't
    serve
[ ] Landing pages: prices,
    areas, answers
[ ] Merchant Center feed
    complete (Shopping)
[ ] Results compared by
    campaign and date

Most of these lines belong in a normal weekly routine already. Our 20-minute Google Ads checklist covers search terms, conversions and ads every week, so ads in AI Mode add a question to each block rather than a new job.

A worked example: a pool-supply shop in Canada

Here’s how an invented online pool-supply shop in Canada, one of the 10 new countries, might respond. It runs a Shopping campaign and a Search campaign with phrase and exact keywords such as “pool vacuum” and “algae treatment”.

  • What changes without any action: the Shopping campaign is eligible for both kinds of matching, so its products can appear for exploratory questions like “why is my pool green”. The Search campaign’s phrase and exact keywords qualify only for direct searches.
  • Week 1: the owner reads search terms for both campaigns and adds negatives for questions the shop can’t serve, such as public pool opening hours and pool jobs.
  • Week 2: the product pages get plain-text answers to the questions that show up most, such as how long an algae treatment takes, and the feed’s titles, prices and shipping details are checked against the site.
  • Week 3: with conversion tracking confirmed, the shop starts an experiment on the Search campaign that tests broad match keywords against the original, and leaves the Shopping campaign alone.
  • After four weeks: it compares cost per conversion between the experiment and the original, not AI Mode clicks, which it can’t see separately.

Nothing in that plan needs a new campaign or budget, which matches Google’s description: existing campaigns take part automatically.

Who can leave it alone

Not every account needs to react. If you advertise only outside the listed countries, or only in languages other than English, ads in AI Mode don’t reach your campaigns yet by Google’s current list, though ads above or below AI Overviews already can. A local business on a small budget, with phrase and exact keywords and a working search-terms routine, is already eligible for the direct, high-intent searches and loses little by waiting for its own data before testing broad match.

Whoever you are, the useful part of this change is the reminder: the searches reaching your ads are getting longer, and your negatives, assets and landing pages should keep up.

The bottom line

Ads in AI Mode now run in the US and 10 more countries, in English, with ads in follow-up questions in the US and the UK, Brazil and Mexico planned for Q4 2026. There’s nothing to switch on and no way to opt out. Decide whether each campaign should reach conversational searches through broad match, AI Max, Shopping or Performance Max, keep reading search terms, and make sure your landing pages say what you’d want an AI explainer to repeat.

Do I need a new campaign for ads in AI Mode?

No. Existing Search, Shopping and Performance Max campaigns are eligible automatically, with no separate budget and no extra charge.

Do exact match keywords show in AI Mode?

Yes, when the search shows direct commercial intent. Exact and phrase match keywords aren’t eligible for contextual matching on broader, exploratory questions; broad match, AI Max, Shopping and Performance Max are.

Can I see AI Mode performance separately?

No. Google includes AI Overviews and AI Mode results in aggregate in your campaign and search terms reports, with no separate segment.

Do ads change what Google’s AI says?

Google says no: organic AI answers are generated independently, and being cited organically doesn’t affect your ad eligibility.
