Google expanded ads inside AI Mode to ten more countries on 28 October. That part made headlines. The part that didn't: Google's own help page confirms advertisers can't opt out of those ads separately from Search, and can't see how they perform separately either. Three days later, on the same earnings call, Google told investors that AI Mode's query growth is weighing on Search revenue because those ads monetize worse than regular search ads — without saying by how much.
Put the three facts next to each other and the story changes. This isn't really about ten new markets. It's about a placement that's already running inside your existing campaigns, that you can't isolate in a report, that Google itself just told Wall Street makes less money per ad than the search results next to it.
📋 How this was put together
This is a synthesis of Google's own published pages and public earnings commentary, not a hands-on test — BuzzRiding runs no Google Ads account to verify spend or reporting against. The expansion facts come from Google's official Ads & Commerce announcement of 28 October 2026. The opt-out and reporting language is quoted directly from Google's own Ads Help page on ads in AI Mode. The earnings detail comes from Search Engine Journal's report on Alphabet's Q3 2026 call and 9to5Google's coverage of the stock reaction that followed. No figure below is BuzzRiding's own measurement.
What actually expanded on 28 October
Per Google's announcement, ads in AI Mode are now scaling to Australia, Canada, India, Kenya, Malaysia, New Zealand, Nigeria, Pakistan, the Philippines and Singapore. Google says it plans to expand further in Q4 2026, naming Brazil, Mexico and the UK, with no specific dates attached.
The US also gets a new format: multiturn ads, which can appear on follow-up questions inside an AI Mode conversation, not just the first query. All of it is labelled "Sponsored." Google's one cited performance figure is that click-through rates are "already similar between sponsored and organic product list items" in AI Mode — based on internal US data from 20 August to 3 September 2026, a two-week window the post doesn't otherwise explain.
The part that matters more than the country list
Here's what Google's own Ads Help page says, word for word, about the mechanics underneath that expansion:
Eligibility is automatic. "Existing Search, Shopping, and Performance Max campaigns are automatically eligible." No new campaign, no separate budget, no action required to start showing up in AI Mode.
There's no opt-out. The help page states plainly that advertisers "can't target ads exclusively to AI Overviews or AI Mode, or opt out of showing ads in them separately from Search." Negative keywords and brand exclusions still work as controls — but there is no switch that turns AI Mode off while leaving standard Search on.
There's no separate report. AI Mode performance is "included in aggregate" in your standard Google Ads campaign reports, and AI Mode search terms are folded into your regular search terms report the same way. There is no dedicated segment, filter or breakout that shows what an ad earned specifically because it appeared inside an AI Mode answer rather than a normal results page.
Taken together: if you run Search, Shopping or Performance Max campaigns today, some share of your impressions are almost certainly already appearing inside AI Mode conversations, in ten more countries as of this week, and your reporting cannot tell you which ones, how many, or what they cost versus a standard placement.
Three days later, Google told investors why that might matter
On 28 October 2026 — the same day as the AI Mode expansion post — Alphabet reported Q3 earnings. Google Search & Other revenue came in at $63.35 billion, up 12% year over year but essentially flat against Q2's $63.27 billion. Growth has now slowed three quarters running: 19% in Q1, 17% in Q2, 12% in Q3.
Chief Business Officer Philipp Schindler told analysts that strong AI Mode query growth was one factor weighing on that slowdown, because AI Mode monetizes at a lower rate than traditional search. He did not say lower than what, by how much, or give a dollar figure for the effect. He named two other factors as bigger contributors: currency movements, and a hit to Asia-Pacific retail advertising after the EU ended its de minimis exemption for low-value imports, plus media budgets normalizing after a strong Q2 that included the FIFA World Cup. CEO Sundar Pichai, for his part, said year-over-year query growth was "the highest it's been in the last five years."
As Search Engine Journal pointed out, this is a real reversal in framing. Google has previously said AI Overviews — the summaries shown above standard search results — monetize at roughly the same rate as traditional search. That claim was never extended to AI Mode, the fuller conversational product. This is the first time Google has said, on the record to investors, that AI Mode specifically makes less per ad.
"Your campaigns are probably already running in AI Mode. You can't turn that off, you can't see it separately in your reports, and Google just told investors it's the weaker-earning placement of the two."
Alphabet's stock fell sharply in the days that followed — 9to5Google put the drop at around 12% by 29 October, erasing more than $500 billion in market value, the second-largest such drop it could find after a 2025 Nvidia selloff. But that same report is explicit that the decline was "not directly due to AI Mode itself." The bigger threads investors were reacting to were capital-spending worries over AI data centers, broader fears of an AI-investment bubble, and the open question of whether Google can monetize AI search fast enough before its traditional search inventory shrinks. AI Mode's lower monetization was one part of that story on the call, not the whole of it.
What the rest of this week's coverage says, and doesn't
Several outlets covered the market expansion well on its own terms. BuzzRiding has covered a similar ad-platform expansion before, for OpenAI's ChatGPT Ads update in October, and the pattern repeats here: the launch-day coverage is strong on what's new and thin on what it means for an account that's already running.
Two pieces published this week gave marketers genuinely useful checklists — confirm eligibility, benchmark performance before attributing any change to the new placement, review search terms and landing pages, and ask what placement-level measurement is actually available. Both are worth reading. Neither one, in the pieces BuzzRiding reviewed, put the no-opt-out language from Google's own help page next to Schindler's monetization comment from the same week's earnings call. Read separately, a market expansion and an earnings admission look like two different stories. Read together, they're the same story: a placement advertisers can't turn off, can't measure on its own, and that Google itself says currently underperforms the thing it's attached to.
It's a familiar shape. BuzzRiding's look at Meta Advantage+ found the same gap between a platform's own framing and what agencies running real budgets actually reported back. The lesson carries over: a launch announcement describes the feature; it rarely describes the measurement problem that comes with it.
What you can actually control
Not much changes about what levers are available — and that's worth saying plainly rather than inventing a workaround that doesn't exist. Per Google's own help documentation, the tools that still apply are the ordinary ones: negative keywords, brand exclusions, and the landing pages and ad assets you write. There is no AI Mode-specific bid adjustment, placement exclusion, or reporting segment published as of this week.
What's worth doing instead is building your own before-and-after read, the same discipline BuzzRiding applies to its own Search Console numbers every month: record where your account's core metrics stand right now, then recheck on a fixed date rather than attributing any change you notice this week to a cause you can't actually isolate in the data.
- Pull your current benchmarks today, before anything else changes. Impressions, CTR, cost per conversion, by campaign, for Search, Shopping and Performance Max — whatever you'd normally check monthly, check it now and save it.
- Check eligibility and geography. If you advertise in Australia, Canada, India, Kenya, Malaysia, New Zealand, Nigeria, Pakistan, the Philippines or Singapore, your existing eligible campaigns are in scope as of this week, automatically.
- Review your negative keyword and brand exclusion lists. They're the only documented controls that still apply inside AI Mode placements, so an outdated list does more damage there than it used to.
- Don't restructure campaigns around a placement you can't see. Without a dedicated report, you have no reliable way to credit or blame AI Mode for a given week's results. Resist the instinct to act on a correlation you can't actually isolate.
- Re-check in a month. Google's Q4 expansion to Brazil, Mexico and the UK is still undated. Revisit this once more markets go live, or once Google publishes anything closer to a dedicated report.
💡 Key takeaway
If you run Search, Shopping or Performance Max campaigns, some of your traffic is almost certainly already showing inside AI Mode conversations, now in ten more countries. You can't opt out of it separately from Search, and you can't isolate its performance in your reporting. Three days after confirming the expansion, Google told investors AI Mode ads monetize worse than regular search ads — which is a reason to benchmark carefully, not to panic-restructure a budget around a placement you can't actually see.
The obvious caveat
This is a reading of Google's own published pages and public earnings reporting, not an audit of any live account. Google hasn't disclosed AI Mode's revenue, cost-per-click, ad load or exact monetization gap versus standard search — Schindler's comment was qualitative, not a number. The stock-price reaction cited above involves several causes investors were weighing at once, and the reporting reviewed here is explicit that AI Mode monetization was one thread, not the sole cause. Google's own controls and reporting for AI Mode may change by the time you read this; verify current behaviour directly in your own account rather than assuming the mechanics described here are permanent.
