Google Ads Unveils New Experimentation Tools for Advertisers

Google Ads has rolled out new experimentation and planning tools for Search campaigns and AI Max. The updates give advertisers more flexibility to test campaign changes before implementing them across an account.

One of the key features is a multi-campaign testing option, set to launch in September. This will allow advertisers to test budget and ROI target changes across multiple Search campaigns within a single A/B experiment.

This means advertisers can now evaluate how scaling campaigns affects their bottom line before rolling out changes more broadly. The new capability builds on Google's one-click experiments for AI Max, but expands testing beyond individual campaign changes.
