1. The vast majority of people don't fill in their information.
2. The people who do fill them in tend to join most of the programs on offer.
So what you may say?
Well here is how you can capitalize on these two facts by understanding a third fact:
3. Downline builders pass on referrals up the tree to the first person in the downline tree who has entered their details.
Go to the programs you belong to, find the downline builder and enter your referral URLs and join the programs that you don't belong to then enter those referral URL's as well.
You will start getting random referrals as the 5% in any downline who are active join the programs in the downline builder. The deeper the downline the more benefit you get.
My advice is to put all of your referral URLs into a spreadsheet as this makes it easier to fill out downline builders. When you join up any new traffic exchange fill in these details on Day 1.
I took sometime to follow my advice yesterday and got a referral at I Love Hits and Thumbvu for my efforts.
So the moral of the story is be active and you benefit from the laziness of others.
