To test push ad creatives for nutra offers, it's better to keep things simple and focused. Start with two or three different headlines and images in the same campaign so the data stays in one place. This helps you see what users respond to without spending too much. Many push platforms also allow split testing inside the campaign setup, so you can rotate creatives and find winners faster. Make sure to run the test on one GEO at a time and use a small budget in the beginning. Track everything using a tracker so you know what's bringing results. You can test different angles, such as health benefits or emotional appeal, and compare how they perform. Once you spot what's getting clicks and conversions, pause the rest and scale the winner.
