Google tests ads in AI Mode for users with connected apps

Google has started testing ads in AI Mode for people who connect Gmail and Google Photos to Search, reversing the ad-free position it gave in March. Google confirmed the test on Friday 16 October, and its help page for connected apps now says the summaries and inferences drawn from those apps may be used to show ads.

Ads in AI Mode are not new. What is new is that they now reach users who have switched on Personal Intelligence, the setting that lets AI Mode draw on a person's emails and photos to tailor its answers. Until now Google had said that group would stay ad-free.

What Google said in March, and what it says now

In March, Google said there were no ads for people who chose to connect their apps with AI Mode, and that this was not changing at the time. It added that it expected ads would eventually operate the same way for those users, staying relevant to the query, the context of the response and the person's interests.

Seven months later that future has arrived, at least as a test. Google's statement on 16 October says it is starting to test ads in AI Mode in Search for users who connect their apps through Personal Intelligence.

The help page tells the same story. A copy of the page archived on 11 October has no mention of advertising at all. The current version carries a new question in its common questions section: whether a connected Gmail inbox or Google Photos library will be used to serve ads.

What the help page now says about ads

Google's answer has three parts.

• Ads will not be based directly on a person's Gmail inbox or Google Photos library.
• If apps are connected, Search may reference summaries, excerpts and inferences from them to personalise the experience and do things for the user, and that same information may be used to show ads.
• Personalised ads are never based on sensitive categories such as race, religion, sexual orientation or health, and users can disconnect their apps at any time.

The distinction Google is drawing is between the raw data and what its systems infer from it. The inbox itself stays out of ad targeting. A summary noting a person's hotel booking, preferred brands or dining habits, which Google's own page gives as examples of what AI Mode can draw on, can now shape which ads appear in an AI Mode answer.

Google has also said advertisers will not have access to connected apps. That is consistent with the rest of the help page, which describes the connected data as something Google's own models summarise and reference, with a subset reviewed by human reviewers at Google and its service providers to improve the product.

What advertisers can and cannot control

Google has announced nothing new inside Google Ads for this: its statement and help page describe no new campaign setting, no audience built from connected apps and no toggle to opt in or out of AI Mode with Personal Intelligence, and they mention no new reporting for these impressions. Google has described no way for advertisers to target by connected-app data, and says they cannot see it.

That puts it in the same bucket as most AI Mode placement decisions: Google chooses when an ad is relevant to the query, the context of the answer and the person's interests, and the advertiser finds out afterwards, if at all. It is a different situation from the channel priority tiers Google began rolling out this month, where you can at least rank Search partners and Display and cap what a Low priority channel spends. AI Mode has no such control.

Where it applies, and what that means in Australia

The help page lists Australia among the countries where users aged 18 and over can connect their Google content apps. Google Workspace connection currently covers Gmail and Google Calendar, though Calendar is US English only. Google Photos connection is not available in all regions, and the page does not list which ones.

To connect their apps to Personal Intelligence, a person needs a personal Google Account, Personalized Recommendations switched on, and the apps connected in their Search Services Personalization settings. Gmail users get more personalised answers with smart features in other Google products turned on, and Photos users need face groups (with their own face selected) and location estimates enabled.

Google describes the ads as a test and has not said which markets it covers. So the honest position for an Australian advertiser is this: the feature your customers would need is available here, the ad test may or may not be, and Google has given no timetable. Do not expect to see it in your account.

AI Mode is becoming a paid surface with personal context

The practical significance is less about this week's test and more about direction. Google is building AI Mode into a shopping and task surface, with Universal Cart in Search already live in the US, and it is now willing to put ads in front of the users who have handed over the most context. The ad-free position for connected users lasted seven months.

For a business buying Search ads, that means a growing share of impressions will land in answers that have been shaped by the person's own emails and photos, in ways nobody outside Google can inspect. Two people typing the same words may now get different answers and different ads, and the statement gives advertisers no way to see which version ran.

The organic side of AI Mode is shifting at the same time. AI Mode has supported preferred sources since May, and an early screenshot suggests Google is testing a Source preferences button inside the AI Mode citations panel so they can add or remove sources without leaving the answer. Between Gemini 4 Argon in AI Mode for paid subscribers and these personalisation controls, the answer one customer sees is drifting further from the answer another sees.

What to do this week

• Ask whoever runs your Google Ads account whether the reporting separates AI Mode from the rest of Search. If it cannot, note in your reports that part of Search spend now lands in AI answers, some of them personalised.
• Set expectations with the business before the numbers move. Search terms reports are unlikely to explain why an ad showed in a personalised answer, and the data to explain it sits with Google.
• Do not build anything around connected-app targeting. It does not exist for advertisers, and Google has said advertisers will not have access to the connected apps.
• Keep the relevance basics tight. Google's own description of how AI Mode ads are chosen comes back to the query, the context of the response and the user's interests, which rewards ads and landing pages that match a specific need rather than broad messaging.
• Watch the help page. It is the only place Google has put the change in writing on its own site, and it changed some time after 11 October without a blog post or formal announcement.

The useful next step is to find out, this week, how much of your Search spend is already reaching AI Mode, so you have a baseline before personalised ads in AI answers become the default rather than the test.
