Everybody who runs CPA campigns knows that offers are stuffed with different "IQ test". I am thinking to exclude all IQ tests from my offers, because I think they are too long, and at the end of them visitor probably forgets why he came to my site at the first place. Plus visitor doesn't know he will be asked money at the end of the test. I have no clue what is conversion rate for IQ test offers, but I think it's bad. Anybody has opinion about this?
