Holiday Demand Gen: Shorts Image Ads and One-Tap Landing Pages

Google calls these monthly releases Demand Gen Drops, and the September 2026 post is squarely about the holidays. It has four parts:

The number Google put in the post: advertisers adding Gmail to their Demand Gen campaigns see their image creatives achieve, on average, a 40% increase in conversions at the same ROI. The source is Google internal data (Global, Gmail ads, February 2026). It's an average from the platform selling the ads, so treat it as a reason to test, not a forecast.

The more useful point is about production cost. A good 15-second video takes a shoot, an edit and a sound pass. A strong vertical still takes a good product photo and a designer who respects the safe zones. For a Shopify brand with a modest Q4 budget, a set of six to ten vertical stills can be in market while the video is still being cut.

Scale is the other reason. Google's Demand Gen overview says the campaigns run across YouTube including Shorts, Discover, Gmail, Maps and the Display Network, and cites more than 50 billion daily views on Shorts alone. Vertical placements are where a lot of that inventory sits.

Google's image asset specs for Demand Gen set the baseline. Horizontal, square and a logo are the core set; the 9:16 vertical is the one Google recommends for Shorts, and it's the one most brands are missing.

Google hasn't published what the agent reads, so don't guess at hidden inputs. What's certain is that feed-based video ads pull from Merchant Center, and Google's performance guide recommends connecting the feed to turn ads into what it calls dynamic virtual storefronts. Start with the fields Google's product data specification marks as required:

Before this update, some of the drop-off happened in the ad. Now more people land on the page with less context, fresh from a full-screen image. The page must pick up exactly where the image left off.

Google's Demand Gen performance guide says the system needs at least 50 conversions to build a foundation, and 30 to 50 more after major changes before you judge the result. It also notes that creative changes trigger policy re-review, which takes 24 to 48 hours. Both argue for launching early and changing little in the final week.

Google's overview points to brand, search and conversion lift studies and data-driven attribution for measuring Demand Gen. The performance guide adds that conversion delays are real, so evaluate trends over longer windows (30-day lookbacks are common) and agree on your KPIs before launch, not after the first bad day.

Three practical habits. Compare branded search volume in the weeks after launch against the weeks before. Use Google's "Conversions (Platform Comparable)" column when you put Demand Gen next to Meta, so you aren't comparing different attribution rules. And keep one budget change per week at most during learning, since changes to target CPA, budget or goals reset it.

If you already test creative on Meta, the same discipline carries over: one variable at a time, clear stop rules. Our guide to Meta ads creative testing on a small budget lays out a structure you can reuse.

You can run this in-house if you have a designer who works in vertical formats, someone who edits short video weekly, and a developer who can change product pages quickly. If any of those is missing in October, the calendar will decide for you.

Signs you need help: your Demand Gen campaign has no 9:16 images, your videos are horizontal TV spots, your feed has disapprovals you haven't looked at, or your ads land on the homepage. Creator-style footage is a fast way to fill the video gap; see our notes on UGC ads for Shopify brands.
