This week I came across an article from Clickz which was intended for advertisers, 
but deals with one of the main issues concerning affiliates. The article discussed the importance of audience 
targeting.  After reviewing the trends and technological developments in the field of audience targeting,  the author (Rob Graham) focuses on 5 top elements which set the basics for better ROI – elements which any advertiser must learn and practice to use in his marketing.

One thing that caught my eye was the fact that as basic as these elements
were, the actual truth is that a lot of advertisers are either A) not aware of
them (which I hope is not the case) B) not paying the right attention to
audience targeting or C) not willing to share their insights. For affiliates,
audience targeting insight is highly important and essential to their success.
Everyone wants better ROI; in a business which rewards per action the risk is on
us.  The difference is that we need better ROI in order to profit.

Still, affiliates keep making money, keep growing both in revenue and in
marketing share. So, how do they overcome this obstacle? I thought this would be
a great opportunity to gather the same 5 basic elements of audience targeting
only this time, from the affiliate perspective.
