where it says “number of times the ad should be inserted in a post”
does that mean you have to know how many ads the post should have? or is it about repetition of the same ad?
This needs to be clarified:
It's about setting the maximum number of ad zones inserted into the post. Set it to 5 and, if there is space for 5 to be inserted, you'll get 5 different widget areas. If it's set to 3, there'll be three. If it's set to 20, you'll only get the number of widget areas inserted into the post that will fit.
