Just wondering if anyone has some experience on lowering their max CPC bids. Lets say you have 12% or higher CTR and its your goal to get them under X cents while still getting the most volume they will give you, how many impressions do you find an ad needs for Facebook to feel confident that 12% CTR is accurate to deliver traffic at that bid? Or I guess another way this question could be asked, is what do you find is the impression sweet spot for when the suggested bids become more accurate to reflect how your ads are performing? Thanks
