Microsoft Unveils Game-Changing Performance Max Experiments—What This Means for the Future of Advertising
Ever wondered if you could test-drive a new car before buying it? Well, Microsoft’s latest move feels pretty much like that – but for Performance Max campaigns. They’re rolling out fresh experimentation tools that let advertisers tinker and test campaign tweaks without throwing a wrench in live performance. With “Uplift experiments” measuring real incremental impact and “Upgrade experiments” allowing side-by-side comparisons between old and new campaign versions, the guesswork just took a serious hit. For anyone who’s ever hesitated to flip the switch on a campaign upgrade, this is a game changer. Curious how this shifts the playing field and why Microsoft’s splitting its experiment lanes? Dive in and find out. LEARN MORE.
Microsoft is bringing experimentation to Performance Max campaigns, giving advertisers new ways to test campaign changes and measure incremental impact without disrupting live performance.
What’s new:
- Uplift experiments let advertisers measure the incremental impact of Performance Max campaigns against a control group.
- Upgrade experiments allow advertisers to compare an existing campaign with an upgraded Performance Max version before fully rolling out changes.
Both experiment types are available under Campaigns > Experiments for eligible accounts.
Why we care. Until now, Microsoft Ads experiments were limited to Search campaigns. Expanding testing to Performance Max gives advertisers a safer way to validate campaign changes, optimize performance, and make data-driven decisions before committing budget.
Between the lines. As experimentation expands, Microsoft has also renamed its existing experiment offering to Search optimization experiments, distinguishing it from the new Performance Max testing capabilities. The move reflects Microsoft’s broader push to provide advertisers with more sophisticated optimisation tools across automated campaign formats.
The bottom line. Microsoft is closing a key gap in its Performance Max offering by introducing dedicated experiment types, giving advertisers more confidence when testing upgrades and measuring the true impact of automated campaigns.
