To test different creatives in pop campaigns, it's better to start by running two or three versions at once. Each version should have something different, like headline, image, or landing page. This helps to see which one brings more clicks or leads. It's good to run each creative with the same budget so the test is fair. Try not to change too many things at the same time, because it can be hard to know what made the difference. Once you find what works, use that version more.
