AI Google Ads for E-commerce

Video assets unlock YouTube, Gmail, and Discover placements that are unavailable with image-only campaigns. E-commerce PMax campaigns with full video coverage (all three aspect ratios) see 15-25% more conversions because the algorithm can serve your ads across Google's entire network. Without video, PMax auto-generates low-quality video from your images — uploading custom AdCreate videos is always better.

Provide video in 16:9 (1920x1080), 1:1 (1080x1080), and 9:16 (1080x1920). Videos should be 15-30 seconds with H.264 encoding. Include your product, brand name, and price in the first 5 seconds. Google strongly recommends all three aspect ratios for maximum PMax reach. AdCreate exports all three from a single project.

Google recommends at least 5 video assets per asset group. For e-commerce, aim for 5 videos in each of the three aspect ratios (15 total). Include a mix of product demos, lifestyle clips, and UGC-style testimonials. More creative volume gives Google's ML system more combinations to test and optimize toward your target CPA.

Use both. PMax for broad, conversion-focused acquisition across all Google surfaces. Demand Gen for targeted mid-funnel campaigns on YouTube, Discover, and Gmail where you want more creative control and audience segmentation. Many e-commerce brands run PMax for prospecting and Demand Gen for retargeting with sequential storytelling.
