If I have generated a custom audience that amounts to approximately 50,000 to tout a new elective surgical procedure, what is the likely cost I will be paying for CTR?  The FB documentation on this is horrible; a Google search turned up next to nothing and I have to let the execs know at least a ballpark.  Anybody have any ideas???

I have found that CTR does vary widely with the audience, @danielle-piesowocki and the subject matter.  I’ve found 0.05% to be a good average CTR for ads I’ve run.  Others claim more but could be running ads for “Like this puppy” or something that is going to get a lot of natural clicks.  I’m talking a range of businesses.  If the audience is more enthusiastic, you can have a better click through rate like more in the 0.10 – 0.20% rate. 

I’ve also been in the health market and those ads have run more in the 0.07% but it could also depend on the CTR.  The cost is then determined by the performance of the ad.  You will see a suggested bid range and you will typically pay lower than that click price.  But if your ad performs well, you’ll pay even less.  Ads are running a bit cheaper than I’ve seen them in the past and typically click prices are more in the $0.75 range.  Again you can get lower if your ad is performing well.  Hope that helps!
