So far, I've found 2 ad zones that have produced a sale each.
Is 1 sale per adzone enough for me to keep spending money on it?
My worry is that when I try to scale, I will lose money because 1 sale per ad zone may not be enough.
PPC Coach once said that, in the context of Facebook Ads, I want to see 3 or more conversions per ad set before considering spending more money on that ad set. An ad zone is similar to an ad set.
What do you think?
