Is Google Testing Ads in AI Mode for Users Who Connect Gmail and Photos, and What Does It Change for Companies?

What Did Google Confirm About Ads in AI Mode?

Google confirmed a test, not a launch. According to Search Engine Roundtable, Google told Search Engine Land on Friday, October 16, 2026: “Google is starting to test ads in AI Mode in Search for users who connect their apps through Personal Intelligence, reversing its earlier ad-free approach to the experience” (Search Engine Roundtable). The second half of that sentence reads like a reporter’s summary, and we could not open Search Engine Land’s article to see how it is punctuated there, so we rely on the first half as Google’s statement.

Search Engine Roundtable’s own summary goes slightly further, saying Google “confirmed it will now show ads in AI Mode results with Personal Intelligence enabled.” The statement it quotes says “starting to test,” and we use that wording. Ads in AI Mode are not new in themselves. What is new, as Search Engine Roundtable puts it, is ads in AI Mode “with Personal Intelligence active.”

Personal Intelligence is Google’s name for the personalization in AI Mode. Google’s help page says it draws on past searches and activity saved in a user’s Search Services History, and that a user who chooses to connect content apps lets AI Mode “reference insights from your emails and/or photos to provide responses that are specific to you” (Google Search Help). The connected apps are currently Gmail and Google Calendar from Workspace, “with other Workspace apps coming soon,” plus Google Photos. The page adds that connecting to Calendar is only available in the US in English, and that connecting to Photos “isn’t available in all regions.”

What Did Google Say in March, and What Changed?

In March, Google told Search Engine Land’s Anu Adegbola: “There are currently no ads for people who choose to connect their apps with AI Mode. That isn’t changing right now” (Search Engine Roundtable). The same statement looked ahead: “In the future, we anticipate that ads will operate similarly for people who choose to connect their apps with AI Mode. Ads will continue to be relevant to things like your query, the context of the response and your interests.”

So the October test is the change Google flagged seven months earlier, not a surprise reversal. What moved is the timing. Users who connected Gmail or Photos in the spring were told there were no ads there “right now”; some may now see them.

What Does Google’s Help Page Now Say About Gmail, Photos and Ads?

The help page is the primary document here, and its ad section has three parts. The first is a limit: “Ads will not be based directly on your Gmail inbox or your Google Photos library.” The second is the use: “If you connect your content apps to Search Services, Search may reference summaries, excerpts and inferences from these sources to personalize your experience and do things for you. That same info may be used to show you ads, so they are even more helpful for you” (Google Search Help). The third is a set of assurances: no personalized ads based on sensitive categories, the choice to connect, and the ability to disconnect “at any time.”

A separate answer on the same page addresses advertisers: “No. If you connect your content apps to Search Services, advertisers will not have access to your Gmail inbox or Google Photos.” Search Engine Roundtable reports that the previous version of the page did not contain the passage on ads and connected apps (Search Engine Roundtable). We did not see the earlier version ourselves.

The important word is “directly.” Read together, the sentences say Google will not hand an advertiser a user’s email or photos, and will not key ads to the raw inbox, but may use what AI Mode has already inferred from them. The page uses the same distinction for model training. It says Search services “do not train generative AI models directly on your Gmail inbox” or on Photos imagery or audio, but do train on summaries, excerpts and inferences, and it notes that for a brief email “the summary may just be the email.” Disconnecting an app, it adds, “doesn’t delete any data from your Search Services History.”

How Many People Could Be in the Test?

Google has not said. Neither Search Engine Roundtable nor the help page gives a user count, a country list for the ad test, or an end date. What the help page does publish is where connecting apps is available at all: to users 18 and over in a listed set of countries and territories, grouped by region (Google Search Help).

The chart counts eligibility for the connection, not the ad test, and the gap between the two may be large. The list we read does not include the United Kingdom, Switzerland or any of the EU member states we checked (Germany, France, Ireland, Italy and Spain), so European users are largely outside the pool. Google’s earlier AI Mode ad test for prescription drugs was limited to the U.S., by a Google spokesperson’s account (see our guide on ads for prescription drugs in AI Mode), but that tells us nothing certain about this one.

What Has Google Not Said?

Several things a buyer or a communications team would want to know are not in the pages we read. Google has not said how the ads are labeled inside an AI Mode answer, which ad formats or campaign types are eligible, whether advertisers can choose or exclude the placement, whether it reports results for it separately, or how many users are in the test. For AI Overviews, Google’s ads help page has said that advertisers cannot target that placement directly or opt out of it, as our prescription-drug guide documents, but we found no equivalent page for ads shown to Personal Intelligence users.

Search Engine Land’s own article returned an error when we tried to read it, so any further detail it contains reaches us only through Search Engine Roundtable. We have not used a third-party rewrite of that article that circulated on October 19, because it adds claims we could not match to Google’s pages.

Our recommendation, not a platform rule: treat any figure about “ads in AI Mode” that does not name Google or the outlet that reported it as unverified until Google publishes an advertiser help page for the placement.

Is This the Same as Other Ads in AI Mode?

No. Our earlier guide on prescription-drug ads in AI Mode and AI Overviews covered which categories of advertiser Google allows. This test concerns which users see ads: people who opted in to connect personal apps and were told in March they would see none. Both point toward ads inside AI answers.

The unpaid part of AI Mode is changing at the same time. The same day’s Search Engine Roundtable coverage reports that Google is testing a “Source preferences” button in the AI Mode citations sidebar that opens a user’s preferred sources list, spotted by a user on X (Search Engine Roundtable). Our guide to Google Preferred Sources explains the feature it extends. One test sells space to advertisers; the other gives readers more say over which outlets are cited. Neither can be bought by a company seeking coverage.

What This Means for Anyone Buying a Placement

An ad in AI Mode is advertising. A company that pays for it is buying an ad unit from Google, labeled as such. An earned mention in an AI answer is a different thing: the system picks the sources it cites, and nothing in Google’s pages says payment influences them. Our guide on paying to appear in a ChatGPT answer draws the same line for OpenAI, and our report on 60,000 businesses advertising on ChatGPT shows ads arriving inside other answer engines too.

Four recommendations follow. They are ours, not Google’s:

• Keep earned and paid reporting separate. If AI Mode shows your company both in an answer and in an ad, count them as different results, and do not let an ad report stand in for evidence of earned visibility.
• Reject any promise of a guaranteed AI Mode mention. Google has described a test with no published criteria, and the unpaid part of an answer is not for sale.
• Ask a seller to name the surface. “AI visibility” can mean a citation, an ad, a brand mention or a link. They are different products with different evidence.
• Expect personalization to blur comparisons. If answers and ads are tailored from a user’s apps, a screenshot from one account is weak evidence of what another account sees.

Methodology and Limitations

Four limits apply. First, Search Engine Land’s report returned an error when we tried to read it, so Google’s October and March statements reach us through Search Engine Roundtable, whose founder, Barry Schwartz, is also Search Engine Land’s news editor. Second, the help page is a live document and can change; we read it, and counted its country list, on October 19, 2026. Third, we did not see the test, and no source we read says how the ads look, where they run or how many users get them. Fourth, nothing here says the ads affect rankings, organic citations or traffic; no source we read says that.

Conclusion

Google moved from “no ads” for connected-app users in March to “starting to test ads” in October, and rewrote its help page to say that insights from Gmail and Photos may shape the ads those users see. It has published privacy limits, namely no direct use of the inbox or library and no advertiser access, but not the commercial details. For a company, the uncomfortable point is that the AI answer is becoming a page where paid and unpaid mentions sit side by side and differ by user. The sensible response is to wait for Google’s advertiser documentation, keep paid and earned results apart, and treat any claim of guaranteed AI answer placement as a red flag.
