Demand gen campaigns get a bigger drop, and sensitive categories get a smaller door

What Google's September drop actually gave demand gen campaigns#

The fox reads the footnote before the headline. On 24 September 2026 Google published September’s Demand Gen Drop, four announcements under one friendly line about turning discovery into action. The line is warm. The footnote under the first number is where the story sleeps, and we will follow its scent shortly. First, the four items, because demand gen campaigns now cover Google’s most visual inventory, and a paid search plan that ignores them is a map with a missing county.

Business Agent for YouTube Ads lets viewers “engage with conversational AI alongside video ads with product feeds”, by Google’s description in the Google Ads blog, and advertisers sign up for it rather than switching it on. One-click experiences send a tap on an image ad in YouTube Shorts or Gmail straight to the landing page; on Shorts that needs 9:16 full-bleed images. Affiliate Location Extensions put Promoted pins in Google Maps for retail networks and dealerships. The fourth item is the Gmail figure, which needs handling with gloves.

The bigger move is the quiet one#

Four months before the drop, Google said Google Display Ads has a new home in Demand Gen, in a post dated 26 May 2026. Advertisers can now manage their Google Display Network presence through Demand Gen, which still reaches audiences across “2 million sites, videos and apps” by Google’s count, and the migration is “expected to complete by 2027”. Google’s Demand Gen help page adds the sting in the tail: new campaigns can only be created within Demand Gen, and any remaining eligible campaigns will be migrated automatically.

So the practical read is plain. Demand gen ads are no longer a side dish. They are becoming the default home for display buying and for Google’s video-adjacent formats, which means the house rules matter to everyone, including advertisers whose categories were always shown into a smaller room.

It helps to place the campaign type on Google’s own menu. The help page frames three jobs: Search for performance on Google Search, Performance Max for every Google channel at once with the AI steering, and Demand Gen for the visual, entertaining surfaces where people browse rather than search. That is the honest answer to the demand gen vs pmax question, and we return to it in the FAQ. Demand Gen also lets you pick the channel, so a vertical creator video can run on YouTube Shorts alone, which matters more than it sounds once we reach the small print.

Google’s numbers are Google’s numbers#

Three figures travel with this story, and each one carries its own footnote. Google says advertisers adding Gmail to Demand Gen campaigns see image creatives achieve a 40% increase in conversions at the same ROI, sourced to “Google Internal Data, Global, Gmail Ads, February 2026”. It says advertisers adding the Display network see a 9.5% increase in ROI on average, sourced to Google internal data from August 2025. And it says the food delivery platform GoFood saw a 24% decrease in CPA and 19% higher conversion volume by adding the network.

Read the ladder the way a fox reads a hedgerow: it tells you where the rabbits were counted, not how many are in your field. The Gmail figure is an average across accounts that chose to add Gmail, and the ROI figure is dated a year before the migration it now supports. Neither is dishonest. Both are a vendor describing its own product, which is exactly why the same page offers measurement tools to check them.

An agency practitioner posted the Gmail number within hours of the drop, and to its credit kept the footnote attached.

That is the right reflex. Google’s Demand Gen help page names the checking tools itself: brand, search and conversion lift measurement, plus creative A/B experiments. A lift study on a slice of budget answers the only question that matters, which is whether the gain shows up in your account, in your category, at your price point.

Two questions to put to your Google rep#

First, how many of the accounts behind the 40% were in sensitive categories, given what the help page says about where those categories can serve. Second, whether the 9.5% ROI figure includes accounts that were already in Demand Gen before the Display network arrived. Neither question is hostile. Both save a quarter of confusion, and a good rep will take them as a compliment to the brief.

Where sensitive categories can and cannot run#

Now for the small print that decides the plan. Google’s Demand Gen help page states that “ads in sensitive categories are generally restricted to YouTube inventory and are not eligible to serve on Gmail or the Google Display Network”. That single sentence removes two of the drop’s headline surfaces for an advertiser it describes: Gmail, where the 40% lives, and the Display network, where the 9.5% lives.

The page then softens the edge slightly. Most sensitive categories can serve on the Discover feed on conditions, though never gambling, alcohol or political content. Campaigns must target predefined Google audiences such as Affinity or In-Market segments, and alcohol advertisers are barred from product feeds altogether. That last rule matters for the Business Agent, which runs on video ads with product feeds.

Laid out plainly, the surfaces read like this. YouTube stays open. Discover opens on conditions for most categories. Gmail and the Display network close. We built the table from Google’s own wording, and it is only as good as the passage it summarises, which names gambling, alcohol and political content but does not list every sensitive category. Check your own category against Google’s policies before you budget around a surface.

Three folkfox verticals sit close to this line. Fintech and healthcare advertisers should read the relevant policy pages before assuming eligibility, starting with Google’s healthcare and medicines policy. Gambling advertisers need certification before a single ad runs, spelled out in Google’s gambling and games policy. Our own notes on fintech marketing, healthcare marketing and iGaming marketing cover how those rules shape a channel plan.

There is a quieter signal on the policy side too. Google’s personalised advertising policy update says that from 30 October 2026 it will allow personalised alcohol advertising on YouTube inventory where locally permitted. Whatever the rest of the sensitive-category map looks like, YouTube is where Google keeps loosening, and that makes YouTube ads for business advertisers in regulated categories the surface to learn first.

The Gmail question in Europe#

Even a category that qualifies for Gmail has a second gate if it advertises in Europe. On 1 September 2025 the French regulator imposed “a fine of 325 million euros on Google for displaying advertisements between Gmail users' emails without their consent”, as the CNIL’s own announcement puts it. The regulator counted more than 74 million French accounts affected by the cookie findings, and it ordered measures within six months, or a penalty of €100,000 per day of delay for each company.

The reasoning is older than the fine. In November 2021 the Court of Justice of the European Union ruled, in Case C-102/20, that advertising displayed in an inbox in a form resembling a real email requires prior consent, a point summarised in PPC Land’s explainer on Gmail ads in Demand Gen. The same explainer calls the format’s legal position in Europe unresolved, and we cannot tell you from the public record how Google’s compliance response has landed since the deadline.

That is the honest position, and it is a useful one. It means a European advertiser running demand gen campaigns should not read the 40% as a licence to switch Gmail on. It means a consent question sits underneath the creative, and the answer belongs to your data protection lead, not to a Google rep.

One billing detail helps the separate-ad-group advice. PPC Land notes that Google charges for the teaser click, the first click that expands the collapsed inbox unit, so a Gmail click and a YouTube click are different actions reported under one metric. Split them and you can see what each bought.

None of this makes Gmail bad. It makes Gmail a channel with two conditions attached, and a fox does not walk into a den without sniffing the trail and checking both exits. Good demand gen campaigns are built on that patient prowl, not on the loudest number in the launch post.

Business Agent, budgets and a test plan that survives audit#

Business Agent needs its own paragraph because it is the item most likely to be sold as a revolution. ContentGrip reported on 17 September that Google is inviting eligible U.S. retailers to test the agent inside YouTube ads, and noted that Google has not disclosed conversation reporting or an incrementality method for the beta. Shopifreaks confirmed on 27 September that advertisers have to sign up to get access.

For a regulated advertiser that combination is a reason for patience. An agent that answers questions about your product is speaking in your name, in a category where wording is policed, with no published way to read what it said or to prove it helped. Sign-up interest is fine. A launch date in your plan is not, until the reporting exists.

Budgets are the second trap. Google’s help page recommends a budget of at least 10 times your target CPA for campaigns using target CPA bidding. The rule is easy to nod at and easy to miss, and it is the reason small accounts see demand gen campaigns stall in learning, circling in the undergrowth instead of running. The chart below is illustrative arithmetic, not a measurement.

If you want the test built rather than described, that is the work of our PPC services, and it sits comfortably beside paid social for advertisers comparing Google’s new door with the ones Meta and TikTok already run. Our earlier notes on Google’s agentic commerce update and the AI Max migration audit show the same pattern: the drop is generous, the terms are specific, and the prowl is worth taking slowly.
