Google tests ads in AI Mode for users who connect Gmail and Photos through Personal Intelligence

Google has started testing ads in AI Mode for signed-in users who connect Gmail, Google Calendar or Google Photos to Search through Personal Intelligence. In March 2026 Google said there were no ads for people who chose to connect their apps to AI Mode. According to Search Engine Roundtable, Google told Search Engine Land on Friday 16 October 2026 that it is "starting to test ads in AI Mode in Search for users who connect their apps through Personal Intelligence." Search Engine Roundtable's rendering of the statement describes this as reversing Google's earlier ad-free approach. Google's own help page now says the summaries, excerpts and inferences AI Mode draws from those connected apps "may be used to show you ads."

The change was reported by Barry Schwartz at Search Engine Roundtable on 19 October 2026, who also noticed that Google had updated its Search Help article on connecting content apps with a new question about ads. That help article, Connect your Google content apps to get a Search services experience that's tailored to you, is the primary source for this post, and it was read in full on 20 October 2026. This post sticks to what Google and the trade-press report actually say. Where it moves into interpretation, it says so.

What Google said in March, and what it says now

Ads in AI Mode are not new. What is new is that they can now appear for people who have switched on Personal Intelligence and connected their own Google apps, a group Google had previously kept ad-free.

According to Search Engine Roundtable, Google told Search Engine Land's Anu Adegbola in March 2026: "There are currently no ads for people who choose to connect their apps with AI Mode. That isn't changing right now." In the same statement Google left the door open. It said it anticipated that "ads will operate similarly for people who choose to connect their apps with AI Mode," and that ads "will continue to be relevant to things like your query, the context of the response and your interests."

Seven months later, the test has begun. Google's statement to Search Engine Land on 16 October 2026, as quoted by Search Engine Roundtable, describes it as a test, not a full launch, and the quoted text calls it a reversal of the earlier ad-free approach. Search Engine Roundtable's report adds that the previous version of the help document did not contain the ads question, so the wording quoted below appears to be new.

What the new help page answer says about ads

Google's Search Help article now carries a question titled "If I connect my content apps, will my Gmail inbox or Google Photos library be used to serve ads?" Google's answer has four parts, and each one matters for how the ads work.

• Ads "will not be based directly on your Gmail inbox or your Google Photos library."
• When apps are connected, Search "may reference summaries, excerpts and inferences from these sources to personalize your experience and do things for you." Google then says: "That same info may be used to show you ads, so they are even more helpful for you."
• Google says it does not show personalised ads based on sensitive categories, and names race, religion, sexual orientation and health as examples.
• Users choose whether to connect their content apps and can disconnect them from Search services at any time.

A second question on the same page asks whether Google will share a user's Gmail inbox or Google Photos library with advertisers. Google's answer is "No," and it says advertisers will not have access to a connected user's Gmail inbox or Google Photos.

Put plainly, Google is drawing a line between the raw content in someone's inbox or photo library and the derived information AI Mode produces from it. The raw content is not the ad signal, by Google's account. The summaries and inferences AI Mode generates while answering a question can be.

Timeline of Personal Intelligence and ads in AI Mode

The table below lists the dated events in this story as the sources report them.

What Personal Intelligence is, and which apps connect

Google's help page describes Personal Intelligence in AI Mode as a feature that uses previous searches and activity saved in a user's Search Services History to tailor suggestions. Users can extend it by connecting Google content apps, which lets AI Mode "reference insights from your emails and/or photos." Google's example is using past restaurant reservations to personalise an answer when someone asks for restaurant recommendations.

The connectable apps, per the help page as read on 20 October 2026, are Google Workspace (currently Gmail and Google Calendar, with other Workspace apps described as "coming soon") and Google Photos. Two limits apply. Connecting Google Calendar is available only in the US in English. Connecting Google Photos "isn't available in all regions."

The scope is wider than AI Mode. The help page says that connecting content apps means all Search services may access Workspace and Photos, and it lists those services as Google Search (including AI Mode and Discover), Maps (including Ask Maps), Shopping, Flights, Hotels, Translate and News. Google's statement about the ads test refers to AI Mode in Search specifically. It does not say whether the other services will carry ads informed by connected apps.

The help page also gives Google's own illustration of how the data is used. Someone looking for weekend getaway ideas or clothes for a trip might get an AI Mode answer that draws on past purchases found in Gmail, or on data in their Google Photos library, to reflect "hobbies, interests, preferred brands and dining preferences." In Relevant Audience's reading, preferred brands and past purchases are the kind of signal advertisers value, which makes the ads question the one marketers should read closely.

Who can see these ads

Google has not said where the ads test is running. What the help page does say is who can connect content apps in the first place, which sets the outer limit of who could ever be in the test.

• Users must be 18 or older and signed into a personal Google Account.
• Personalized Recommendations must be turned on in Search Services Personalization, and the user must actively connect the apps.
• The supported-countries list on 20 October 2026 includes Thailand, alongside markets such as the United States, Canada, Australia, Japan, India, Indonesia, Malaysia, Singapore, Vietnam and the Philippines.
• The supported-languages list includes Thai.
• The supported-countries list as read on 20 October 2026 does not include the United Kingdom or EU member states such as Spain, Italy or the Netherlands.

The help page also says that connecting some content apps "may not be available in your country, territory or language" and that Google is "gradually rolling out to more users, languages, and regions." So a market on the list is eligible for the feature in principle. It does not mean every user there has it, and it says nothing on its own about where ads are being tested.

Ask Maps has a separate, narrower list. Personal Intelligence in Ask Maps is available in English in the US, Canada, India and Australia, Hindi in India, Japanese in Japan, Indonesian in Indonesia, Spanish in Mexico, Portuguese in Brazil and French in Canada. Thailand is not on that list.

What Google has not said

The announcement is short, and most of the questions advertisers will ask are not answered by any of the sources. These are the gaps as of 20 October 2026.

• Which countries or languages the ads test covers, and what share of Personal Intelligence users are in it.
• Which campaign types or ad formats can serve in these sessions.
• Whether advertisers get any setting to opt in, opt out or bid differently for Personal Intelligence traffic.
• Whether these impressions will be reported separately from other AI Mode traffic.
• How long the test runs, and what would decide a wider launch.
• Whether Maps, Shopping, Hotels or other Search services will also show ads informed by connected apps.

None of that is in Google's statement or on the help page. Any claim elsewhere about markets, formats or launch dates for this test should be checked against Google before it is relied on.

The privacy terms around connected apps

The ads answer sits on a help page that also sets out how connected-app data is used for AI training and human review. Those answers were already on the page in the 11 October 2026 archived copy, before the ads question was added, but they are the context in which users decide whether to connect, and so they shape who ends up in the ad audience.

Google's help page says that if users connect their content apps, Google may use that data to improve its services, including by training generative AI models. It says Search services do not train those models directly on a user's Gmail inbox, Calendar or other Workspace apps, or on imagery or audio from Google Photos. Instead, summaries, excerpts, generated media and inferences may be used. Google adds that where an email or file is brief or particularly relevant, "the summary may just be the email or file."

On human review, the page says a subset of connected-app data processed by AI Mode and Ask Maps is reviewed by human reviewers, including trained service providers. Google says it disconnects those interactions from the user's account and reduces personal information first, except to address abuse or harm. Twice, the page asks users not to connect apps containing information they would not want used for training or seen by a reviewer.

One more detail matters for anyone thinking about consent. Disconnecting a content app does not delete data already stored in Search Services History, according to the help page, and that history can still be used for product improvement. It has to be managed separately at activity.google.com.

How this connects to earlier coverage

Relevant Audience covered the Calendar connection on 17 July 2026, when Google added Google Calendar to Personal Intelligence in AI Mode in the US. That post focused on Calendar being the first connection that could both read and create entries. Ads were not part of that announcement.

On 16 July 2026, Relevant Audience reported an SE Ranking study that found AI Mode showing text ads on nearly 30 percent of US commercial queries, and on 7 September 2026 it covered Google testing exact and phrase match ads in AI Mode. Both concerned ads in standard AI Mode sessions.

What is new on 16 October 2026 is the audience. The personalised sessions where AI Mode can read a user's email and photos had been the one part of AI Mode without ads. That exception is now being tested away.

Analysis: what changes for advertisers

The points below are Relevant Audience's reading of the sources, not statements from Google.

The signal behind an ad can now include things the user never typed. In a normal search, the query and the page context carry most of the intent. In a Personal Intelligence session, AI Mode may already know from a booking email that the user is flying to a particular city next month, and Google says that same inferred information may be used to show ads. An advertiser cannot see or target those inferences, and Google has said advertisers get no access to the underlying apps. The practical effect is that ad relevance in these sessions depends more on Google's reading of the user than on the advertiser's keyword list.

There is no announced lever. Google has not described a targeting setting, bid adjustment or report for Personal Intelligence traffic. Until it does, the reasonable assumption is that advertisers will not know whether a given AI Mode impression came from a personalised session. That makes this hard to measure directly, and it is one more reason to watch AI Mode performance as a whole rather than wait for a dedicated report.

The answer and the ad share context. Google's March statement said ads would stay relevant to the query, "the context of the response" and the user's interests. In a personalised answer, the response itself may already name places, dates or products drawn from the user's own history. An ad that sits beside that answer has to make sense next to it, which puts weight on landing pages and assets that answer a specific need quickly.

The audience is self-selected. Only adults who switch on Personalized Recommendations and actively connect apps are eligible, after reading a help page that warns them about training and human review. That is likely to be a smaller, more engaged group than AI Mode users as a whole, though no source gives a number.

What this means for Thai marketers

Thailand is on Google's list of supported countries for connecting content apps, and Thai is on the list of supported languages. That means Thai users can, in principle, connect Gmail or Photos to Search. It does not mean the ads test is running in Thailand: Google has not said which markets it covers, and none of the sources mention Thailand in connection with ads.

Two limits are worth keeping in mind for the Thai market. Calendar connection is US and English only, so a Thai user's connected data would come from Gmail and, where available, Photos. Ask Maps personalisation is not listed for Thailand at all.

For advertisers running Google Ads campaigns in Thailand, there is nothing to switch on or off today, because Google has announced no setting. The useful work is preparation: knowing which of your campaigns already appear in AI Mode, checking that landing pages answer specific, personalised needs (a trip, a booking, a repeat purchase) rather than generic ones, and watching AI Mode results for changes once the test widens. Because AI Mode answers and ads now draw on the same personal context, brands that care about how they appear in the answers themselves should look at their visibility in AI search answers alongside their paid search.

Frequently asked questions

Are ads now showing in AI Mode for Personal Intelligence users?

Google told Search Engine Land on 16 October 2026, as reported by Search Engine Roundtable, that it is starting to test them, which means some users who connect apps through Personal Intelligence may see ads in AI Mode. It is a test, not a full launch, and Google has not said how many users are included.

Does Google use my Gmail inbox to choose ads?

Not directly, according to Google's help page: ads "will not be based directly on your Gmail inbox or your Google Photos library." Google does say the summaries, excerpts and inferences AI Mode draws from connected apps may be used to show ads, and that advertisers do not get access to the apps themselves.

Is the ads test live in Thailand?

Google has not said. Thailand is on the help page's list of countries where users can connect content apps, and Thai is a supported language, but no source names the markets where ads for Personal Intelligence users are being tested.

Do advertisers need to change anything?

No action is required, because Google has announced no new setting, campaign type or report for this traffic. Advertisers who already appear in AI Mode should watch performance there and make sure landing pages fit specific, personalised needs.

Can users avoid these ads?

Users who do not connect their content apps are not part of Personal Intelligence app-based personalisation, and Google says connected users can disconnect at any time. Standard AI Mode already carries ads, so not connecting apps does not mean an ad-free AI Mode.

Google's reversal took seven months, and the details that matter most to advertisers (markets, formats, reporting) are still unannounced. Relevant Audience will follow the test as Google says more.
