One of the biggest challenges that we face in the "safelist world" is knowing what site to join and focus on. There are hundreds if not thousands of traffic sites, but very limited time to test them.
There is a shortcut that helps us. It is the 80/20 rule, or Pareto's Principle, which says that 80% of your results will come from 20% of your actions. In our case, 80% of your signups will come from 20% of all the traffic you send to your offers.
I analyze my statistics every week and the rule always works. I use over 100 traffic sites, but 80% of the signups come from the top 10-20 sites. If I have a busy week and can't devote as much time to getting traffic, I concentrate on those 20 sites and see very little difference in the number of signups I get.
Last week, I got 79% signups from 12% of the traffic sites I use.
