Yesterday, Facebook charged me $6 for 500 impressions that lead to 1 click so, basically, i paid $6 for 1 click(in gaming niche). 1. What OBJECTIVE shud i choose while running Facebook ad for my CPA offers? I choose to get CONVERSION as my objective...and pay per impression as payment method. AND 2. What leads to cheaper clicks....broad audience(1 million+ target) or narrow audience(less than 10,000 target).?
