Key Takeaway
Google announced three Demand Gen updates on September 24, 2026: Business Agent for YouTube ads, one-tap image ads on Shorts and Gmail, and affiliate location expansion in Maps. Which ones apply differs by advertiser.
What does each of the three features do?
| Feature | What it does | Who it is for and conditions |
|---|---|---|
| Business Agent for YouTube ads | Viewers ask product and brand questions to a conversational AI that comes with the video ad, without leaving the viewing screen. Uses the product feed | Pre-registration required |
| One-tap image ads | One tap on an image ad opens the advertiser's landing page. On Shorts, it applies when you upload a 9:16 full-bleed image ad | Advertisers running ads on Shorts and Gmail |
| Google Maps affiliate location expansion | Captures local demand with promotion pins shown while people browse, search or get directions on Maps | Retail networks and dealerships |

Which advertisers should look at what first?
The feature to look at first depends on the channels you run.
- If you already run YouTube video ads and a product feed, you can consider pre-registering for Business Agent. First check that the product information in your feed is current. Keep a separate record of whether you applied and your approval status.
- If you run image ads on Shorts or Gmail, check that your existing creative fits the new specs.
- If you have physical stores or a dealer network, Maps promotion pins may apply to you. They do not apply unless you have a franchise or dealer structure.
Rather than forcing in a feature that does not apply, testing just one that matches the channels you run makes comparison easier.
How should you read the performance figures?
The figure that image-asset conversions rose by an average of 40% at the same ROI for advertisers who added Gmail to Demand Gen is Google's internal data and comes with conditions. It does not mean your account will see the same result. It is safer to check first with a small experiment.
How should you prepare creative and landing pages?
To use one-tap image ads on Shorts, you need a 9:16 full-bleed image. Rather than stretching existing landscape creative, recomposing it for the vertical format leaves less cropped out on screen. Since one tap opens the landing page directly, also check mobile load speed and whether the first screen matches the ad.
How should you design the experiment?
Set a period and budget, and compare your existing setup with the new feature under the same conditions. Recording your current campaign's conversion figures before you start makes it easier to compare the effect afterward. If your conversion definition changes midway, the results are hard to interpret. Also keep in mind that traffic itself changes at year-end, which can skew comparisons. Google's average figure is only a reference, so judge by your own account's conversion data.
Where can you find more?
The Demand Gen Drops Hub and Google Ads Help are the reference points. Features may roll out gradually by region and account, so check for updates again.
