Can I gain page rank if I set up a affiliate program that provides affiliates links like: http://www.mywebsite.com/?affid=222 I heard that affiliate software that uses 301 redirects can pass page rank. Is it true?
affiliate marketing is the best link bait way that i know. if there is not nofollow on the links , pr will pass from those links. and i see that most of the people are not using nofollow on their affiliate links
Re the OP's question it's hard to say but the more relevant question is to get the affiliates to send you the traffic and help *them* make money. Otherwise you won't get many of those links pointing to you for long so worrying about passing PR is moot.
use post affiliate pro to gain direct links to your website but still track them onto a sale. It will use the referrer url to track the sale to you.
