Ads in AI Overviews and AI Mode: What Changes for You

Google put Sponsored results inside its AI answers and did not ask your permission. The ads come out of the Search, Shopping and Performance Max campaigns you are already funding. Google Ads' own help page answers the question every owner asks next in one word: no, you can't opt out of serving ads in AI Overviews.

So you are already in. The useful questions are narrower: which of your campaigns feed that surface, what it does to the organic listing you paid an SEO to earn, and what you can actually control. Most of what agencies will sell you here is guesswork dressed as strategy. Here is what Google has documented and what the data says.

Are your ads already running inside AI Overviews?

If you run a Search, Shopping or Performance Max campaign in the US in English, almost certainly yes. Google's own documentation on ads and AI Overviews states that text and Shopping ads from existing Search, Shopping and Performance Max campaigns are eligible to show within AI Overviews, with no separate campaign type and no opt-in step.

There are two different placements and people conflate them. Ads above and below an AI Overview run in all 200+ markets where AI Overviews exist, from your Search, Shopping, Performance Max and App campaigns. Ads inside the AI Overview are narrower: English only, mobile and desktop, in 12 countries including the US.

One detail that decides this whole topic for some readers: Google says it currently does not show ads in AI Overviews for sensitive verticals including finance, healthcare, gambling, alcohol, adult and politics. If you run a dental practice, a med spa or a financial-advisory firm, the inside-the-answer placement may not touch you at all today. Verify what your account is actually serving before anyone charges you to optimize for it.

How does Google choose which ads appear in an AI answer?

Google matches these ads against two things — the user's query and the content of the AI Overview itself — and then runs the normal auction. An ad has to be relevant to the generated answer, not just the search term, which is why the winners are often not the accounts with the tightest keyword lists.

Google's own example: someone searches 'why is my pool green and how do I clean it.' The query is not commercial. The AI answer talks about testing water and vacuuming debris. Google reads commercial intent out of the combination and serves pool-vacuum ads. That is the whole model — the answer creates the ad slot.

Which leads to the part Google states plainly and most owners miss: it requires AI-powered targeting to reach this surface. Broad match on Search, or keywordless targeting through AI Max, Performance Max, Shopping campaigns or Dynamic Search Ads. An account built on 40 exact-match keywords is largely invisible inside AI Overviews.

Read that as the price of admission, not a free upgrade. Broad match plus Smart Bidding with no conversion tracking on booked calls is how service businesses light money on fire. If you are weighing the automated route, our take on whether Performance Max is right for a service business applies here without changes.

What does an AI Overview do to the organic listing you paid to earn?

It takes a large bite out of it. Ahrefs compared 300,000 keywords using Google Search Console data and found that the presence of an AI Overview correlates with a 58% lower clickthrough rate for the #1 organic result — with position 3 down 46% and position 10 down 19% (Ahrefs, December 2025 data).

Behavior data says the same thing. Pew Research Center tracked 900 US adults across 68,879 Google searches and found that when an AI summary appeared, users clicked a search result on just 8% of visits, versus 15% when no AI summary was present. They clicked a link inside the summary itself on only 1% of visits (Pew, March 2025 data).

So the honest framing of the new ad slot: Google is selling you paid access to a surface that is absorbing the clicks your organic listing used to get for free. Treat the ad spend as compensation, not as a windfall.

The organic side still pays, though — being inside the answer matters. Seer Interactive analyzed 5.47 million queries across 53 brands and found that being cited inside an AI Overview delivers 120% more organic clicks per impression than appearing on the same SERP uncited, though still 38% fewer than a SERP with no AI Overview at all (Seer, 2026). That is why we treat SEO, GEO and AEO as one program in one retainer instead of an upsell — and why the citation mechanics in our Google AI Mode optimization guide belong next to your ads plan, not in a different department.

Can you opt out of AI surfaces, and what levers do you actually have?

You cannot opt out. Google Ads states it twice on the same page: you can't opt out of serving ads in AI Overviews, and you can't directly target ad placements in AI Overviews either. There is no checkbox in either direction. What you have instead is a set of indirect throttles.

• Negative keywords — Performance Max now accepts up to 10,000 campaign-level negatives, which is your bluntest control over what AI-matched traffic you buy.
• Match type — dropping broad match shrinks your AI Overview eligibility, at a real cost in reach. It is a trade, not a fix.
• Bid targets — a hard tCPA or tROAS is the only lever that reliably caps what a fan-out query is allowed to cost you.
• Conversion definition — count booked calls and qualified forms, not clicks or 'engaged sessions', or automation optimizes toward the wrong thing.
• On the organic side, Google's only AI opt-out is nosnippet, data-nosnippet, max-snippet or noindex — which means opting out of Search snippets entirely. Nobody sane does this.

How do you measure clicks from AI surfaces separately?

Today, you can't — and any agency claiming otherwise is selling you a report built on inference. Google Ads offers no segmented reporting when ads serve inside AI Overviews; they are simply reported as Top Ads. On the organic side, Google Search Central confirms that AI Overview and AI Mode traffic is folded into the standard 'Web' search type in Search Console rather than broken out.

That leaves proxies. They are imperfect and you should say so out loud rather than pretend precision you don't have.

• Segment your search terms report by query length. Ahrefs found AI Overviews trigger on 46.4% of 7+ word queries versus 9.5% of one-word queries (146M SERPs, September 2025) — long, question-shaped terms are the closest thing to an AI-surface fingerprint you have.
• Watch conversion rate and CPC on that long-query bucket separately from your core money terms. If cost per booked call diverges, you have found the AI-driven spend.
• Track Top Ads impression share over time. Ads in AI Overviews are counted there, so movement with no bid or budget change is a signal worth chasing.
• Instrument the phone. Call tracking with a recorded outcome is the only clean read on whether this traffic converts to work you can bill.

Should you change your bidding or budget because of AI Mode?

Not much, and not yet. In its 2025 year-in-review, dated December 8, 2025, Google says it is testing ads in AI Mode in the US, where ads may appear below and integrated into AI Mode responses. More importantly, AI Overviews trigger on just 4.3% of commercial-intent and 2.1% of transactional-intent keywords, versus 21.4% of informational keywords (Ahrefs, 146M SERPs, September 2025). Only 7.9% of local searches trigger one.

Translation for a contractor or a law firm: 'emergency ac repair near me' and 'personal injury lawyer' are mostly untouched. The AI answer lives upstream of that, on 'why is my ac blowing warm air' and 'do I have a case if I was rear-ended.' That is the demand this surface monetizes — earlier, cheaper, less ready to buy.

So do not rebuild your account around it. Run it as a fenced experiment: one broad-match or AI Max campaign, its own budget, a hard target CPA, and a decision date. We put a 90-day kill switch on any channel like this — no qualified leads in 90 days, it gets cut, no discussion. That discipline is the whole reason our paid ads management is month-to-month with no lock-in: if it isn't working, you shouldn't be trapped paying for it.

What should a service business do about this in the next 90 days?

Spend two hours auditing, ring-fence 10-20% of budget for a real test, and change nothing else. This is a shift worth understanding and a terrible reason to blow up a working account.

• Confirm what you are serving. Check whether your vertical is even eligible — finance and healthcare are on Google's excluded list for ads inside AI Overviews.
• Fix conversion tracking first. If Google's automation is going to pick your queries, it must be optimizing to booked calls and qualified forms, not raw leads.
• Build the negative list before you widen match types, not after the invoice arrives.
• Baseline your Top Ads impression share and long-query cost per lead this month, so you have something to compare against next quarter.
• Fund the organic side of the same surface. Being cited in the AI answer is worth 120% more organic clicks per impression than being uncited (Seer, 2026), and it costs no CPC.
• Set the kill date now. Ninety days, no qualified leads, campaign off.

The uncomfortable summary: Google took clicks from your organic listing, then offered to sell some of them back through a placement you can neither target nor refuse. The counter-play is not clever bidding. It is owning both sides of the answer — the ad and the citation — and measuring in booked calls so you can tell when either one stops paying. That is how we build paid ads programs for HVAC companies, law firms and B2B teams. If you want a straight read on what your account is actually buying inside these surfaces, Get my free audit.
