Data-Driven Creative Testing in 2025: What Actually Works

Your creative tests aren’t broken, your data is.

A clean, structured system to fix attribution and scale winners (without wasting ad spend).

ROAS says your ads are working.

Your revenue says otherwise.

Most creative tests fail because the data underneath is messy. Attribution’s off. EMQ scores are low. And Meta’s feeding you winners based on half the picture.

So what do you do? Keep testing into the void? Or fix the backend first?

I put together a simple system to clean up your testing structure, tighten attribution, and actually find creative winners that scale.

🎯 Use ABO to isolate creative performance
