One of the easiest ways to build your downlines is to fill out the REFERRAL BUILDER.
This is especially important on Instant Commissions sites since the way you make MONEY here is to GET REFERRALS.
Take the time.
Fill in your ENTIRE Affiliate URL (not just the login or affiliate ID).
For Instant Commissions sites, I recommend that you UPGRADE to at least GOLD so you get every other sale (50%).
Encourage YOUR REFERRALS TO DO THE SAME!
