A couple of questions on PPC (eg adwords, facebook) to promote clickbank products. 1) is it permissible for the ad to point to the hoplink (directly or via redirect), or must it go via a landing page on my site. 2) is there any advantage on sending PPC traffic to an intermediate landing page? IE, it seems to present another opportunity for visitors to leave the process, but can pre-selling increase the % going from ad to purchase? Thanks in advance.
