First off if you are getting a ctr of .3+ you should be bidding CPM not CPC.
Next, if you have a campaign that has a daily budget of $25 but has a "ongoing" end dating, facebook is going to take there time in getting you any traffic. A easy way around that is to set a end date 1 hour out, this way facebook ads will try to eat up as much of the budget before the time runs out (it seems like its a priority type thing, if you set your budget to run on for a month, facebook will get the people's ads that are set to run out the fastest so they get as much money as they can).
