Testing AI Max just got easier and more granular for Search campaigns. Eligible accounts can now use a 1-click setup to create a 50/50 experiment automatically through Recommendations. Additionally, advertisers can manually refine experiments at the ad group level.
The updated Google Ads help page provides new insights into configuring these experiments.
Users can selectively enable or disable Search term matching or Asset optimization for specific ad groups in the treatment arm, while the control arm maintains base campaign settings. This enables a more tailored testing approach.

The updated setup guide also supports selecting multiple campaigns with granular controls and brand settings, allowing further customization within the experiment. Advertisers seeking to explore AI Max in more depth can refer to the updated FAQs.
