I hear alot about the need to mask your affiliate ID. I notice with flash ads, obviously the link is hidden. So if I make some ads in the flash format, will my affiliate ID still register with the merchant's website, still giving my credit for the sale (if any)?
It is better to mask your affiliate id. You can choose flash ads or anything else. and you should ensure that... all hoplinks must be targeted to the top level of a new or existing window.
