Some advertisers offer multi-tier programs that distribute commission into a hierarchical referral network of sign-ups and sub-partners. In practical terms, publisher "A" signs up to the program with an advertiser and gets rewarded for the agreed activity conducted by a referred visitor. If publisher "A" attracts publishers "B" and "C" to sign up for the same program using his sign-up code, all future activities performed by publishers "B" and "C" will result in additional commission (at a lower rate) for publisher "A".
I would personally agree with linkshare.com as a great affiliate marketing platform to join as a publisher. Here’s why. Back in 2005 when I knew nothing about affiliate marketing and was using blogger.com as a free blogging platform without any experience whatsoever and joining Walmart.com as my first official affiliate program, I was able to insert Walmart affiliate in its in my blogger blog and earn a $72 commission. I was onto affiliate marketing for life from there.
