I just started testing some new ads on FB and I'm getting a terrible CTR at the moment. However, they launched sunday night so I feel like I need to let them run for maybe a week or so to really see whether or not my adcopy is decent. When you guys start testing new ads do you just run them in this way for a week or so and then daypart and optimize according to that initial data? Or is there any way to research what times would be best to run ads for different demo.'s?
