Ads in AI Overviews: What Changes in Your Shopping Campaign

Search for “why is my pool green and how do I clean it” in the US and Google may answer with an AI Overview about testing the water and clearing debris. Inside that Overview, a Shopping ad for a pool vacuum can appear. Nobody bid on that question. The ad matched because Google read the question, read its own answer, and decided a vacuum was the next step.

That example comes from Google’s own help page on ads in AI Overviews, and it describes where things stand. Ads can show above or below AI Overviews in every market where Overviews appear. Inside the Overview, Text and Shopping ads from existing Search, Shopping and Performance Max campaigns are eligible in English, on mobile and desktop, in twelve countries including the US, Canada, Australia and India. Sensitive verticals such as finance, healthcare, alcohol and gambling are excluded. You can’t opt out, you can’t target the placement on its own, and these ads report as Top Ads with no separate segment.

Google has kept building from there. At Google Marketing Live in May 2026 it announced AI-powered Shopping ads, where Gemini picks your most relevant products for a search and writes a custom explainer on why one may suit the shopper, and it added native checkout to its Direct Offers pilot for merchants on the Universal Commerce Protocol. So the question for anyone running Shopping is practical. What changes when the click, and sometimes the purchase, can happen inside Google’s answer?

The ad matches the answer, not only the query

A classic Shopping campaign matched products to what someone typed. Inside an Overview, Google weighs the query and the content of the Overview together. The pool question isn’t commercial. The answer about cleaning a pool is.

That has a direct consequence for your feed. Google’s own guidance for these placements is to keep product descriptions, pricing, promotions, shipping, returns and other attributes current, and to supply enough images and video to power richer units. A title that says “Pool Vacuum 3000” describes the product. A description that explains it clears algae and debris from a pool floor describes the problem the Overview is discussing. The second one gives Google something to match.

It also changes what eligibility means. Google says these placements need AI-powered matching: broad match, AI Max for Search, Performance Max, Shopping campaigns or Dynamic Search Ads. An account running tight exact match on product names will rarely reach the questions where Overviews appear.

Your feed writes the pitch

With AI-powered Shopping ads, Gemini writes the explainer that sits with your product, on why it may be the right choice. In AI Mode, the formats Google is testing, Conversational Discovery ads and Highlighted Answers, carry what Google calls an independent AI explainer beside the advertiser’s creative. Your headline is no longer the whole pitch. A model reading your feed and your pages writes part of it.

So the product feed stops being a technical file someone updates twice a year. It becomes the brief the model writes from. Merchant Center supports conversational attributes for descriptions that reflect how people ask, and Google announced an AI performance insights tool to compare your share of voice on AI surfaces against similar brands, rolling out in the US, Canada, Australia, India and New Zealand. Clean titles, complete attributes and honest descriptions are the creative work of this campaign type. This is the kind of work where ecommerce marketing that treats the feed as the storefront pays off first.

The click arrives better informed, or later, or never

Think about the shopper who does click. She has read an answer that compared options and explained what to look for. By the time she reaches your product page she is further along than a shopper who clicked a Shopping ad from a plain product search. Your landing page should meet her there: price, availability, delivery and returns up front, without making her start the research again.

Then think about the shopper who doesn’t click, because the purchase completes on Google. Under the Universal Commerce Protocol, Google says the retailer stays the merchant of record whether the shopper checks out with Google Pay or goes through to the merchant’s site. You still make the sale. What you lose is the visit: the session in your analytics, the pixel fire, the visitor who joins your remarketing audience. A campaign that relied on site visitors to feed its retargeting will see that pool thin out as more buying happens inside Google’s surfaces.

And because AI Overview placements report as Top Ads, you won’t see any of this broken out. The changes arrive blended into your existing numbers.

What to change in the campaign

Four adjustments follow from the mechanism.

1. Rewrite descriptions around the problems your products solve, in the words a person would use to describe the problem. Fill every attribute Google asks for, including shipping and returns.
2. Read the search terms report for longer, question-shaped queries. Some will be profitable research moments. Others are informational traffic you don’t want to pay for, and negatives are still your main control; we covered that discipline in ways to cut wasted ad spend.
3. Judge performance on blended results and incrementality rather than last click. With no placement segment and some checkouts happening on Google, last-click reports undercount what these placements do.
4. Build audiences that don’t depend on site visits: customer lists, first-party data and upper-funnel video. Demand created elsewhere is what makes a shopper recognize your product in an Overview, the link explored in why CTV is search marketing’s missing link.

None of this needs a new campaign type. It needs a performance marketing approach that reads blended results, not placement by placement, because the placement report doesn’t exist.

Paid and organic are sharing the same box

An AI Overview carries two kinds of presence: the paid product and the sources the answer cites. The ad buys a slot beside the answer. The citations decide what the answer says about your category. Brands that appear in both get the answer and the next step. That organic half works the way we laid out in why AI search names your competitor and not you.

In a Shopping campaign built for Overviews, the product feed is the ad and the answer is the keyword. Manage both that way.

Frequently Asked Questions

Can I opt out of showing ads in AI Overviews?

No. Google’s help documentation states there is no opt-out and no way to target the placement exclusively. Ads from eligible Search, Shopping and Performance Max campaigns enter the auction for these placements automatically when they’re relevant to both the query and the Overview’s content. Your controls are the usual ones: negative keywords, product exclusions, feed content and bidding. If a product or query type shouldn’t appear, exclude it at the campaign level.

How do I see how my ads perform inside AI Overviews?

You can’t isolate them. Google reports ads in AI Overviews as Top Ads and offers no segmented reporting for the placement. The practical approach is to watch the search terms report for longer, question-style queries, compare blended conversion trends over time, and use incrementality tests where your volume allows. Merchant Center’s AI performance insights, announced in May 2026, is set to add share-of-voice data on AI surfaces in several markets.

Which campaign types can show ads in AI Overviews?

Text and Shopping ads from existing Search, Shopping and Performance Max campaigns are eligible to show inside AI Overviews in the supported markets. Google recommends AI-powered matching to reach these placements, meaning broad match, AI Max for Search, Performance Max, Shopping campaigns or Dynamic Search Ads. Ads can also appear above or below Overviews in every market where Overviews appear, using the normal auction.

Do ads in AI Overviews appear outside the US?

Yes. Ads inside AI Overviews are available in English on mobile and desktop in twelve countries, including the US, Canada, Australia, India, Singapore and New Zealand, according to Google’s help page. Ads above and below Overviews run in every market where Overviews are available. Sensitive verticals such as finance, healthcare, alcohol, gambling and politics are excluded from placements inside the Overview.
