For facebook ads. I have had a few ads running but was curious on how you know when to turn an ad off, as I think my problem has been turning the ads off too early. Also, how long is the learning phase? When can I expect sales if it goes well? Is it normal that an ad has a higher CPM in the beginning? I'm thinking of sending people to a price calculator page, is that a good idea? I have seen competitors do it and it worked. My budget is $35 a day in Denmark for a web agency, where I sell websites.
