I know the real answer for this question is "to test". That said, I have a question.
I sell 10 CDs (actually mp3) of audio which is a lecture about something.
I am thinking about giving away the CD1 for my squeeze page. However, it is just an introduction. So does not contain so much information.
(FYI: it is the shortest CD and I need it to explain my whole idea about the product...it is not exciting as other CDs, I admit.)
So, what I am wondering about is would giving this kind of introduction CD make the listener want to have "the main" CDs or not.
I am wondering if I should rather make new audio for giving away which contains more information of my method (lecture).
Again to test is the best way I know, but I'd just like to know your experiences/input etc.
