Anyone currently advertising on facebook. I'm currently testing out facebook and the cost per click vs cost per impression. Ran the exact same ad and demographics each for 24 hours on a $25 dollar budget. Both are based on an average cost per click ratio. The numbers are quite different even though the ads are the same. CPC 78 clicks 62,470 impressions 0.125% click through CPM 46 clicks 231,523 impressions .020% click through And ideas?
