Testing new ad ideas works best when you compare small changes at a time. You can create two or three versions of the same ad with different headlines, images, or messages. Running them to the same audience helps you see which one performs better. Keeping the test short and low-cost stops you from wasting money. Looking at clicks, comments, or the time people spend on the page gives clues about what catches attention. After you find the strongest idea, you can improve it further. What do you think?
