AI Mode ads in the UK: you’re probably already in

Google plans to bring AI Mode ads to the UK before the end of 2026, and you won’t need to sign up for them. Google says existing Search, Shopping and Performance Max campaigns are automatically eligible. If you run Google Ads, your ads are probably already in the pool. The useful work now is checking what Google will build those ads from: your product feed, your landing pages and your match types. It’s also worth deciding how you’ll judge the results, because AI Mode won’t get its own line in your reports.

What’s changing with AI Mode ads, and what isn’t

AI Mode is the AI search tab Google started rolling out in the UK on 28 July 2025. You ask a longer question, Google writes an answer, and you can keep asking follow-ups. For its first year in the UK, it carried no ads.

On 28 October 2026, Google said it was scaling ads in AI Mode in ten markets: Australia, Canada, India, Kenya, Malaysia, New Zealand, Nigeria, Pakistan, the Philippines and Singapore. The UK got a single line: “In Q4 2026, we plan to expand to additional locales, including Brazil, Mexico, and the United Kingdom.” That’s a plan rather than a launch date, and Q4 runs to 31 December.

When the ads arrive, they’ll be labelled “Sponsored”. Google says text and Shopping ads can show within or alongside the AI answer. Google may also add short explanations written by its Gemini models, which it calls AI explainers. Advertisers can’t write, edit, approve or opt out of them.

AI Mode isn’t AI Overviews

The two are easy to mix up. AI Overviews are the AI summaries at the top of a normal results page. AI Mode is the separate tab built for longer conversations.

Are your ads already in the pool?

Probably. Google’s help page says: “Existing Search, Shopping, and Performance Max campaigns are automatically eligible to serve ads within AI Overviews and AI Mode.” There’s no AI Mode campaign type and no separate budget. Google says you aren’t charged extra to take part, and the ads go through the same auction as the rest of Search.

What does vary is how much of AI Mode each campaign can reach. Google matches ads in two ways. Direct query matching covers questions that are clearly about buying. Contextual matching looks at the question and Google’s answer together, so an ad can show on a broader research question, such as which electric car suits a family with a long commute.

The last row matters because AI Mode questions are long. Google says they are, on average, three times longer than traditional searches (US data, May 2026). An account built mostly on exact and phrase match will only show on the narrow slice of questions where someone is clearly ready to buy.

Can you opt out? Not separately. Google calls AI Overviews and AI Mode “core experiences within Google Search”, and says you can’t target ads to them on their own. The controls you already use still apply: negative keywords, brand exclusions and asset pinning.

Why brand-heavy accounts should look twice

If most of your budget goes on your own brand name, AI Mode may pass you by. In its US tracking, Adthena found that brand searches “rarely trigger AI ad placements” and warned that advertisers who lean on brand terms “risk being close to invisible in AI search”.

That’s one company’s tracking. It hasn’t published a percentage, and Google hasn’t said the same. Your brand ads will keep showing on the normal results page too. But it fits how people use AI Mode. Someone who already knows your name types it and clicks through to your site. AI Mode gets the longer questions people ask before they’ve picked anyone, and if your competitors are eligible for those questions and you aren’t, they’ll be the ones in the answer.

So check how your spend splits between brand and non-brand, and whether your customers’ research questions are covered by anything other than exact match. Keep brand in its own campaign, and use brand exclusions in Performance Max and AI Max so the two don’t overlap. We explain how in Performance Max campaign structure.

Your AI Mode ads checklist

1. Check your product feed and prices

Google’s advice for Shopping ads in AI search is to keep feeds up to date and review descriptions, pricing, promotions, delivery and returns. It also wants enough good images, and video where you have it, for its richer ad formats.

For UK retailers, start with price. Merchant Center says prices for every country except the US and Canada must include VAT, and the price on your landing page must match the price in your feed. Get that wrong and Google can warn or suspend your account. A suspension takes your products out of Shopping everywhere, not just AI Mode.

• Prices include VAT and match between the feed and the page.
• Each product page shows one clear price. On sale pages, the sale price is the one Google can see, not only the old “was” price.
• The feed updates at least daily if your prices or stock change often.
• Titles and descriptions say what the product is, who it’s for and what it does.
• Delivery and returns details are filled in.

Merchant Center also has newer, optional attributes, such as question-and-answer pairs and related products. PPC Land reports that Google’s documentation describes them as “primarily intended for use in conversational experiences such as AI Mode”. Fix the basics before you add these.

2. Check your landing pages

Google uses your website to write and route these ads. In AI Max, text customisation builds ad copy from your existing ads, landing pages and assets. If you turn AI Max on, Final URL expansion is on by default, and Google says it “may replace your Final URL with a more relevant landing page based on the user’s search query.”

• Add URL exclusions for pages that should never be landing pages, such as careers, blog posts, terms, login pages, discontinued products and old offers.
• Check that prices and offers on your pages match your ads and feed.
• If you rely on pinned headlines, for example for regulated wording, note that Google doesn’t use pinned assets when it picks a different landing page. If that wording must appear, you may need Final URL expansion off.
• Make sure each page answers the obvious questions: what it is, who it’s for, what it costs and what happens next.

3. Review your match types and negatives

If your Search campaigns are mostly exact and phrase match, you’ll miss most of AI Mode. Broad match or AI Max is the way in, but test it before you switch.

UK agency equimedia has shared results from its own AI Max tests. Brand terms, competitor names and loosely related searches all slipped through. In one test, the AI Max side spent more than twice as much as the control on what was meant to be an even split. And an existing exact negative failed to block a near-identical search.

• Run AI Max as a Google Ads experiment with a 50/50 split, and watch spend as well as conversions.
• Build negatives before you widen your match types, then check they block what you meant them to. Our guide to negative keyword match types covers the common traps.
• Read your search terms every week while the test runs.

4. Save a benchmark before launch

Google says results from ads in AI Overviews and AI Mode are included “in aggregate” in your standard campaign reports, and the search terms report includes these searches in aggregate too. There’s no separate AI Mode line. Your best evidence will be a before-and-after comparison, so you need the “before” now.

• Save a dated record of the last 90 days: cost per acquisition, ROAS, conversion rate, cost per click, brand versus non-brand, and results by device and campaign type.
• Check your conversion tracking. Bid on the conversions that matter, such as sales and qualified enquiries, and remove duplicates.
• After launch, watch top-of-page impressions and click-through rate, and look for longer, question-style searches in your search terms.
• Allow for the season. Google’s planned window overlaps Black Friday and Christmas, so compare with the same weeks last year as well as the month before.
• Judge the results on enquiries and sales.

5. Leave the budget alone for now

AI Mode ads cost nothing extra to join and don’t need their own budget. As UK agency Koozai puts it: “The priority isn’t to spend more simply because a new format becomes available.” If you want to test broad match or AI Max, give the test a capped budget and an end date.

What not to promise yet

• A launch date. Google has said Q4 2026 and nothing more specific.
• Ads on follow-up questions. Google has launched these “multiturn” ads in the US only, and hasn’t announced them for the UK.
• AI Mode reporting. Google hasn’t announced a separate report.
• Benchmarks. The figures so far are early and from the US. Google says click-through rates are similar for sponsored and organic product listings within AI Mode (US data, 20 August to 3 September 2026), but that compares product listings with each other and gives no actual rates. An SE Ranking study of 50,032 US commercial keywords found AI Mode showed text ads on 29% of them, rising to 54% for keywords costing $10 or more a click. If the UK follows the same pattern, expensive categories will see the most ads.
