Do you find that sometimes your Facebook ads will do well – and sometimes they don’t? One common mistake that leads to this is targeting multiple interests in one ad set. When trying to reach new audiences (not your custom audiences), you need to test. You won’t know what interest target is right and which one is wrong when you target multiple interests in one ad set. Use multiple ad sets if you want to test multiple interests – that way you know which ones work and which ones don’t.
