If you select the Conversion objective, what percentage of the Facebook audience you are targeting might you reasonably expect to see your ads? Say you have an audience of 1, 000, 000 interested in chocolate. How many people Facebook views as being ‘likely to convert' might you expect to see your ads? 1%? 25% 50%? I understand this will vary a lot in practice depending on a number of different factors but can anyone share what a sensible reach to expect might be, of an audience you're targeting, if you choose a Conversion objective? Thanks in advance!
