When starting with push ad creatives, the first things to test are the image, the headline, and the description. These are the parts people see first, and they help decide if someone will click or not. The image should be eye-catching but still make sense with the offer. A clear and short headline that tells what the ad is about can make a big difference. The description supports the headline and adds a little more detail. These three elements work together, so testing different versions of each helps you find what gets the most clicks. Also, test call-to-action texts like "Get started" or "See offer." They may look small, but they also affect clicks. Once you find what works, you can then focus on deeper parts like landing pages. What would you want to test first if you were running push ads?
