Google Ads just launched a beta that lets you test creative side-by-side in Demand Gen campaigns.
Here’s how it works:
1. Pick your image/video variants → Google duplicates your campaign
2. You define budget, traffic split, and experiment duration
3. Google tracks performance to show what visuals drive results

You can make edits to the control sync across both arms, but don’t edit the treatment arm after launch.
