Google Performance Max built‑in A/B testing for creative assets

How it works:
Google Ads is testing a new feature that lets advertisers run A/B tests on creative assets within a single Performance Max campaign. 

Advertisers pick a campaign, create an asset group, and set up a control (existing ad) and a treatment (new ads). Some assets can be shared between them. They can choose how to split traffic (like 50/50), run the test for a few weeks, and then use the best-performing assets. 

What’s the benefit?
This lets marketers test creative assets directly in Performance Max campaigns. It shows which headlines, images, videos, or descriptions perform best, cutting guesswork and making optimisation faster and easier.
