Google personalised ads from Gmail and Photos: what changes

On 16 October Google changed one sentence in its privacy policy. Since 2021 it read: "We don’t show you personalized ads based on your content from Drive, Gmail, or Photos." It now says "Google Photos" and carries eighteen more words: "unless you choose to make data from these services available to other Google services that support personalized ads". Android Authority spotted the change a week later, and LinkedIn had its loudest week of the autumn. Most of the posts stopped at the headline. Here is what the sentence does, why it is good news for anyone who sells real things, and what we are changing in the accounts we run before it reaches Europe.

What Google actually changed about Gmail, Photos and ads

Since 16 October 2026, Google’s privacy policy lets personalised ads draw on summaries and inferences from Gmail and Google Photos, for people who opt in to Personal Intelligence. That is the feature that lets AI Mode in Search read your Gmail and Photos to answer with your own context: your hotel booking, or the running shoes in your pictures. It launched in January 2026 for paying subscribers in the United States and is now in beta worldwide, except the European Economic Area, Switzerland, the United Kingdom and Nigeria.

Per Google’s help page, ads "will not be based directly" on your inbox or your library; Search draws "summaries, excerpts and inferences" from them, and "that same info may be used to show you ads". Google confirmed to Search Engine Land that it is testing ads in AI Mode for people who connected their apps. Advertisers get no new lever, no audience and no setting: whatever the context is worth reaches you through the auction, which is why what you feed the auction matters more from here. Google even went back to its 2017 blog post promising that consumer Gmail would no longer be scanned for ads, and appended a note. A nine-year-old post with a fresh update is a rare thing on the internet.

Three facts survive the headline: Google’s personalised ads from Gmail and Photos are opt-in, advertisers never see the content, and none of it is switched on in France today.

Why this is good news if you sell something real

Advertising has always paid for a guess about intent. Search was the best guess available because the person typed the question. Personal context is a better one: the lease is ending, the old CRM is being complained about in a thread with twelve replies. An auction that knows this shows fewer ads to people who will never buy, which is the entire job of performance marketing once you measure it on revenue.

None of this is new. In 2015, researchers at Cambridge and Stanford showed that a model fed ten Facebook likes judged someone’s personality better than a work colleague did; with 70 it beat a friend, with 150 a family member, with 300 a spouse. Meta has used conversations with Meta AI to personalise ads since 16 December 2025, outside the EU, the UK and South Korea. Google is the last of the big platforms to bring personal context into its ads, and it arrives with an opt-in and a published rule: no personalisation on sensitive categories such as race, religion, sexual orientation or health. For an advertiser, that is the better version of the deal. Your ad reaches people who ticked a box saying they wanted to be understood.

What Personal Intelligence does not do yet, especially from Paris

The sentence goes further than the product. Today the product is a beta for adults with personal accounts who connect their apps on purpose, in the countries where it has launched. The ads being tested run in AI Mode, where, as with AI Overviews, reporting is folded into ordinary Search placements, so a personal-context click will look like any other click in your account until you measure it on a holdout.

In Europe, the opt-in does not exist yet, which leaves a few months to get the account ready, as anyone who has shipped a feed fix on 24 November will tell you.

One more thing, since every post on this change ends with it: young people search on TikTok now and the open web is over. The 40% figure behind that comes from a 2022 Google study about where 18 to 24 year olds look for lunch. In Adobe Express’s 2026 survey, 49% of US consumers have used TikTok as a search engine, 4% of Gen Z would rely on it over Google, down from 8% in 2024, and 89% of Gen Z prefer Google over every other platform. If you sell lunch to 22-year-olds, TikTok search is a channel and you knew it before this autumn. The insurer, the flight and the CRM still get typed into Google, which is where the personalisation is arriving. We covered the prophecy in April.

Five things we are changing in Google Ads before it reaches Europe

1. Feeding the auction our own signal. A personalised auction optimises toward whatever conversion you report, so the quality of that signal caps everything else. Enhanced conversions, Consent Mode and offline conversion imports are the minimum we set up before touching a bid. Google’s own figures: consent-mode modelling recovers more than half of the conversion journeys lost to consent choices, and early adopters of enhanced conversions saw a median 5% lift in Search conversions. Modest numbers that compound every day the model learns from them, provided the conversion it learns from is the one that makes you money.
2. Writing for a question nobody has typed yet. AI Max and broad match already match on meaning. Assets, sitelinks and landing pages now have to answer a context, the trip in three weeks or the budget in the email, rather than a keyword. Headlines that describe the advertiser are the first thing we cut.
3. Making the site readable by agents. Structured data and a Merchant Center feed whose prices and stock match the page. Google’s Universal Commerce Protocol already lets a shopper check out without leaving AI Mode, in the US for now. When the purchase happens there, a feed error costs the order, and there is no click in your report to warn you.
4. Measuring on a holdout. When the auction knows the inbox, platform reports will claim credit for sales the inbox had already decided. Geo holdouts and conversion lift tests are how you find out what the ad added. Our accountant prefers this method too.
5. Dating the European switch. The day Personal Intelligence opens in the EEA, we note the week and compare search term mix, CPC and conversion rate before and after, account by account, with nothing else changed that week.

Why Google rewrote the sentence

Nobody rewrites a five-year-old promise for a Labs experiment (the legal review alone would have outlasted the experiment). Google did it because the next decade of its ads business runs on context that people agree to share, and the advertisers who gain from it will be the ones whose data, creative and measurement are in order on the day the setting reaches their market. Everyone else pays for sales the inbox had already made, and the platform report will be happy to take the credit. Which side of that line you land on is decided before the switch flips, by what the auction has learned from your account by then, and by how much of the dashboard you choose to believe. If you want to know where your account stands, book a call and we will read it together.
