I have a CPC FB ad with great CTR. I cloned it with the only diff being the billing=CPM.
Interestingly enough, the CPC ad has a high CTR (and therefore lots of clicks and revenue for FB). While the CPM ad has a CTR ~1/7th of the CPC ad, and therefore a REAL high effective CPC.
Whats the deal? If I didn't know better, I'd suspect FB is taking bogus click money from the CPC ad, since when I pay by CPM I get very few clicks.
