I assume that something is monitoring the traffic going from this site to the online stores though?
Ayup! It happens when the link is executed from our start point here at DarkMatters. Any link that is published first in a post or on this site becomes a link that has the commission.
Before, in the old days, sites used to spend a lot of work actually following affiliate programs that were painstaking to maintain, monitor and update.
Now, almost any link can help, as long at Viglink has spoken to the company first to add them to the roster.
Doing it like this is kind of like invisible advertising instead, and keeps normal ads off our boards for all our registered members, while instead attempting to raise funds by working with a purchase they would have already made online.
