September 2026 Google Ads Update – Demand Gen Adds Faster Paths to Conversion

Granular analysis and first look

Google is making Demand Gen more actionable across YouTube, Gmail and Google Maps. For advertisers focused on efficient Google Ads growth, Granular’s PPC management experts see these changes as another push toward shortening the distance between product discovery and conversion. Google announced the updates in its September 24, 2026 Demand Gen Drop.

What’s New in September’s Demand Gen Drop

The latest release focuses on three areas: conversational product discovery, fewer clicks between an ad and landing page, and more opportunities to connect digital advertising with physical locations.

Business Agent Brings Conversational AI to YouTube Ads

Google is introducing Business Agent for YouTube ads that use product feeds. Viewers can interact with conversational AI alongside the video ad to ask questions about a product or brand without leaving their viewing experience.

For advertisers, this could move more product education into the ad experience itself. Brands with complicated products, large catalogs or common pre-purchase questions may have an opportunity to address hesitation earlier in the buying journey.

The quality of product-feed information may become even more important as these experiences evolve. Google already positions product feeds as a way to turn Demand Gen creative into a browsable storefront, making accurate and useful product data a foundation worth reviewing.

One-Click Experiences Reduce Friction on Shorts and Gmail

Consumers can now reach an advertiser’s landing page with one tap from qualifying image ads on YouTube Shorts and Gmail. On Shorts, the experience applies when advertisers upload 9:16 full-bleed image assets. Google recommends the 9:16 format for Shorts and lists 1080 x 1920 as the recommended resolution for vertical Demand Gen images.

The Gmail change is especially notable because Google reports that advertisers adding Gmail to Demand Gen campaigns saw image creatives generate an average 40% increase in conversions at the same ROI. That figure comes from Google internal global Gmail Ads data from February 2026, so individual advertiser results will vary.

Reducing an extra interaction between the ad and website could help advertisers capture more users while intent is still high. The practical next step is to watch whether higher landing-page traffic translates into incremental conversions rather than judging the change on clicks alone.

Affiliate Location Extensions Expand Demand Gen in Google Maps

Retail networks and dealerships can now use affiliate location extensions to capture local demand through Promoted pins in Google Maps. Those ads can surface while people browse, search and navigate.

This creates another connection between upper-funnel discovery and an offline purchase journey. It could be particularly useful for manufacturers whose products are sold through retailers and brands that depend on dealer networks rather than company-owned stores.

Advertisers should keep in mind that Google currently does not allow campaigns to serve exclusively in Google Maps. Promoted pins are part of the broader advertising experience rather than a Maps-only campaign type.

What Demand Gen Advertisers Should Test

The common theme across all three updates is reduced friction. Rather than adding another major campaign type, Google is giving advertisers more ways to turn attention into action within the surfaces where discovery is already happening.

Advertisers should consider:

• Testing 9:16 image creative: Build full-bleed vertical assets specifically for the Shorts experience instead of relying only on repurposed square or landscape creative.
• Measuring post-click quality: Compare conversion rate, CPA and revenue—not just traffic—after one-click experiences begin generating additional landing-page visits.
• Improving product-feed data: Review product titles, descriptions and other feed information as conversational AI becomes more closely connected to product-based ads.
• Evaluating local opportunities: Retail brands, manufacturers and dealerships should review whether affiliate locations can connect Demand Gen activity with nearby purchase options.
• Watching incrementality: Google’s benchmarks are useful context, but campaign-level testing should determine whether the new inventory and experiences produce additional business value.

Key Takeaways

Google’s September Demand Gen Drop makes it easier for consumers to move from discovering a product to learning more, visiting a site or finding a nearby location. Business Agent brings conversational AI closer to YouTube advertising, while one-click Shorts and Gmail experiences remove steps from the path to a website. Promoted pins with affiliate locations add another option for advertisers with retail or dealership footprints.

For PPC teams, the update puts additional emphasis on creative formats, product-feed quality and measurement. The opportunity is not simply to activate every new feature, but to test whether each one creates a more efficient path to meaningful conversions.

Demand Gen continues to evolve from a primarily discovery-focused campaign into a format with more direct paths to action across Google’s visual ecosystem. These September updates give advertisers new ways to answer product questions, drive website visits and connect online discovery to local stores.

As holiday competition increases, advertisers using Demand Gen should review their vertical creative, product feeds, landing-page measurement and location strategy so they are prepared to test the new experiences where they make sense.
