Google AI Mode Ads: What Ecommerce Advertisers Should Check Before Black Friday

Yes, Google ads can show in AI Mode, but in the US it is still a test with no separate reporting. Before Black Friday on 27 November 2026, ecommerce advertisers should check four things: which campaigns are eligible, whether native checkout was switched on for their store, their Merchant Center attributes, and how they will read results.

Key Observations

• Ads inside AI Overviews are live in English in 12 markets, including the US, Canada and Australia, with no opt-out and no separate reporting.
• Google still calls ads in AI Mode a US test. Its new AI Mode formats run on AI Max for Search and Performance Max.
• In a small test reported in early September 2026, exact and phrase match keywords can serve text ads in AI Mode for explicit, direct intent.
• Stores on Shopify and other Universal Commerce Protocol platforms were auto-enabled for native checkout in AI Mode and Gemini. You can switch it off.
• Universal Cart began rolling out in the US on 15 October 2026. Google’s launch post does not mention ads.
• Google Ads cannot separate AI Mode delivery from regular Search, so build a weekly baseline now.

Every fact below was checked at its source on 26 October 2026 and is linked with its date. Google changes these surfaces often, so treat anything marked as a test as a test.

Google expanded ads in AI Mode to 10 more countries on 28 October 2026; for every other change this month, see this month’s Google Ads updates.

Many guides mix up the two surfaces. AI Overviews are AI summaries on a normal results page. AI Mode is a separate conversational search experience with in-depth answers and follow-up questions, as Google describes on its AI Mode marketing page (updated 20 January 2026). The ad rules differ for each.

This post covers ads, checkout and feeds only. Our AI Mode SEO guide is due on 21 November 2026.

Do Google ads show in AI Mode?

Yes, in a test. Google’s own AI Mode marketing page says it is “testing ads in AI Mode in the U.S.” (published October 2025, updated 20 January 2026). On 13 May 2026, Google described new AI Mode ad formats powered by AI Max and Performance Max, still in testing with no launch dates.

Google says these formats sit inside the AI answer, labeled as ads, but it named no formats, test markets or dates.

What have advertisers actually seen in AI Mode?

• 13 May 2026: Direct Offers, deals inside AI Mode answers that AI Max and Performance Max advertisers create in Google Ads. Retailers can also manage offers from Merchant Center.
• 31 August 2026: a Shopping ads carousel inline in an AI Mode response, spotted by Brodie Clark.
• 15 September 2026: text link ads labeled Sponsored inside AI Mode answers, spotted by Sachin Patel. Google made no statement.
• 13 October 2026: Google confirmed it is testing text and Shopping ads for certain pharmaceutical products in AI Mode and AI Overviews, in the US only.

For Black Friday, assume some Search, Shopping and Performance Max traffic already serves inside AI answers. You cannot buy that placement on its own, so get the campaigns, feed and checkout settings behind it ready.

Which campaigns can show ads in AI Mode and AI Overviews?

For AI Overviews, Google’s Help page lists text and Shopping ads from Search, Shopping and Performance Max campaigns as eligible inside the overview, in English, in 12 markets. For AI Mode, Google ties the new formats to AI Max for Search and Performance Max, with a small exact and phrase match test on top.

The Help page also keeps sensitive verticals out of AI Overviews ads, including alcohol, adult, gambling, finance, healthcare and politics. Wine and spirits stores should not plan around this placement.

Google’s AI Mode marketing page says turning on AI Max is one of the best ways to appear in AI Mode and AI Overviews, and cites 27% more conversions at a similar CPA or ROAS than campaigns built mostly on exact and phrase match. That figure is Google’s internal data from non-retail advertisers, so it says little about a Shopping-heavy store.

Our view: turning on AI Max or moving budget into Performance Max is a structural change, and Smart Bidding needs stable data after it. If a change cannot get two clean weeks before 27 November, make it after Cyber Monday.

Can exact match keywords show in AI Mode?

Sometimes. Google’s Ads Liaison, Ginny Marvin, told Search Engine Roundtable (4 September 2026) that a small experiment lets exact and phrase match keywords serve text ads in AI Mode, but only where the searcher’s intent is explicit and direct. Newer formats such as Highlighted Answers stay with AI Max and Performance Max.

Before this, PPC Land (6 September 2026) noted that AI Mode access needed AI Max, Performance Max, or broad match with Smart Bidding, and that Google named no countries or scope for the test. Anthony Higman, who first spotted the change, argues in the Search Engine Roundtable piece that it is bigger than a small test.

How do I run an exact match test before Black Friday?

You cannot opt in to the test, but you can spot it if it reaches your account.

1. Pick 10 to 20 high-intent exact match keywords, such as brand plus product or a model number.
2. Record four weeks of impressions, CTR, CPC and conversion value now, before holiday traffic arrives.
3. Check search terms weekly. Longer, question-style terms can hint at wider matching, but they are not proof of AI Mode delivery.
4. Judge trends over weeks, not days. PPC Land notes an exact match row can mix literal matches, close variants and AI Mode impressions, with no way to tell them apart.

Our own approach: we start new campaigns on exact match, because broad match only works once an account has conversion data. Exact terms cost more per click, but the traffic matches. When we open up to broad, we build negatives upfront in phrase and exact, at account level.

Can I opt out of ads in AI Overviews or AI Mode?

No for AI Overviews: Google’s Help page says you cannot opt out of serving ads there and cannot target the placement directly. For AI Mode, we found no opt-out setting in Google’s documentation as of 26 October 2026. Your levers are campaign type, match types, negatives and budget.

If a product should never appear in a conversational answer, exclude it from Shopping and Performance Max. Native checkout is a different setting: it controls where the purchase happens, not whether an ad shows.

How do I see AI Mode results in Google Ads?

You can’t, directly. PPC Land reported on 6 September 2026 that Google Ads does not let advertisers separate AI Mode delivery from regular Search, and Google’s Help page says ads in AI Overviews are reported as Top ads with no segment. Use Merchant Center’s AI performance report and trend comparisons instead.

Per PPC Land, Google has not said whether reporting will split out AI Mode if the test grows, so plan to measure AI surfaces by trend this Black Friday.

What can I use instead of an AI Mode report?

• Merchant Center AI performance insights, now available in Australia, Canada, India, New Zealand and the US (16 September 2026). It compares your brand’s share of voice across AI Mode and AI Overviews.
• The report’s newer sections. Search Engine Roundtable reported on 9 September 2026 that AI search intent, AI search terms and AI attributes were added.
• A weekly sheet of impressions, CTR, top impression rate and conversion value per campaign, with each Google change dated in a notes column.
• Third-party trackers, compared in our AI Overviews tracking tools guide.

Why are my Shopping impressions down but CTR up?

Mike Ryan of Smarter Ecommerce shared data, reported by Search Engine Roundtable on 7 September 2026, showing median Shopping ad impressions falling from about 1.85 million to 1.4 million between mid-2025 and mid-2026, while median CTR rose from 1.20% to nearly 1.55%.

That is their sample of 175 billion impressions, not Google data, and they link the shift to AI Overviews spreading. If your account shows the same shape, check conversion value before raising bids.

Was my store enrolled in native checkout, and how do I turn it off?

If you sell on Shopify or another platform that supports Google’s Universal Commerce Protocol, possibly yes. In emails reported on 22 September 2026, Google told merchants that eligible products were automatically included in native checkout on AI Mode and Gemini. Shopify stores can switch it off under Sales channels, then Agentic.

Native checkout lets a shopper buy in AI Mode or the Gemini app with Google Pay, without visiting your site. Per the same report, products had to be live on the Shopify storefront and in Merchant Center. Google’s email said merchants keep ownership of customer relationships, data and sales.

How do I check if native checkout is on?

1. Look for a September 2026 Google email saying your products are now eligible for native checkout.
2. In your Shopify admin, open Sales channels, then Agentic.
3. In Merchant Center, check whether any data source sets the native_commerce attribute.

How do I turn native checkout off for some products only?

Use the native_commerce attribute. Google’s Merchant Center Help page (checked 26 October 2026) lists one sub-attribute, checkout_eligibility. True shows a Buy button; false or empty keeps a standard listing. The page covers item-level control only, with no account-wide switch. If your store was auto-enabled, set false explicitly.

Google strongly recommends a supplemental feed, so your primary feed and Ads campaigns stay untouched. In Sheets or TSV, the column header is native_commerce(checkout_eligibility), beside your id column. Then check the Data sources tab for processing errors.

Should I keep native checkout on for Black Friday?

It depends on the product. Turn it off for items that need your own checkout, such as engraving fields, gift notes, bundles or on-site upsells. Keep it on for simple products where a faster purchase is the point.

Also check how these orders are counted. A purchase on Google skips your site’s checkout pages, so thank-you page tags will not see it. Google said on 16 September 2026 that UCP integration hub analytics are coming soon, so confirm reporting with your platform.

What is Universal Cart?

Universal Cart is a shopping cart that works across Google Search, including AI Mode, and the Gemini app. Google began rolling it out in the US on 15 October 2026. It saves items from several retailers, tracks price and stock changes, and lets shoppers check out with Google Pay or move items to the merchant’s cart.

Google’s launch post (15 October 2026) says the merchant stays the seller of record and handles confirmations and support. It runs on the Shopping Graph, Google Wallet and the Universal Commerce Protocol. The post does not mention ads.

In a 16 September 2026 update, Google also said merchants using the UCP integration hub in Merchant Center can turn on cart transfer to their own site. It is rolling out in the US, with Australia and Canada early in 2027. Google also invited retailers to a US beta of Business Agent in YouTube ads.

Why does Universal Cart matter for Black Friday pricing?

Universal Cart tracks price drops and stock changes on saved items and surfaces promo codes. A shopper who saved your product in early November could be alerted when your sale starts, but only if sale_price, sale_price_effective_date and availability are correct.

Which Merchant Center attributes matter for AI Mode?

For ads and checkout in AI Mode, the attributes to check first are native_commerce for checkout eligibility, loyalty_program for member pricing, video_link for product video, and accurate price, sale price and availability. Google’s AI performance report in Merchant Center now also flags missing attributes.

Strikethrough member pricing for known members also needs Customer Match lists connected in Google Ads, PPC Land reported on 30 March 2026. Set up the loyalty_program attribute (Help page checked 26 October 2026) first, then the audience.

Retail advertisers can also manage Direct Offers from Merchant Center (13 May 2026). If you use them for Black Friday, match them to the sale prices in your feed.

Our Merchant Center AI attributes guide covers each field with Sheets, TSV and XML examples, and our free feed attribute mapper checks a feed for missing attributes and format errors before you upload it.

What should ecommerce teams check before Black Friday?

Work through the table below by 13 November 2026, two weeks before Black Friday on 27 November. It covers campaign eligibility, the exact match test, native checkout, Merchant Center attributes, loyalty pricing, reporting baselines and negatives. Each row names where to look, why it matters and who should own it.

FAQs

Quick answers for ecommerce advertisers. In short: AI Mode ads are a US test, AI Overviews placements cannot be excluded, Performance Max is eligible, Shopify native checkout can be turned off in your admin or per product, and your Merchant Center feed drives ads and checkout.

Are ads in AI Mode live in the US?

Only as a test. Google says it is testing ads in AI Mode in the US (page updated 20 January 2026). Shopping carousels and text link ads were spotted in August and September 2026, with no general launch date announced by 26 October 2026.

Can I exclude AI Overviews placements?

No. Google’s Help page on ads in AI Overviews (checked 26 October 2026) says you cannot opt out or target the placement. You can only control which campaigns, keywords and products run.

Does Performance Max show in AI Mode?

It can. Google says its new AI Mode formats are powered by AI Max and Performance Max (13 May 2026), and Performance Max is eligible inside AI Overviews. Reporting will not show a separate AI Mode line.

How do I stop Google checkout on my Shopify store?

In your Shopify admin, open Sales channels, then Agentic, and turn off native checkout. For selected products, set native_commerce(checkout_eligibility) to false in a Merchant Center supplemental feed.

Does AI Mode use my product feed?

For ads and checkout, yes. Shopping and Performance Max ads use your Merchant Center data, native checkout covers products in Merchant Center, and member pricing comes from loyalty_program. Feed errors become ad and checkout errors.
