Referrals
Referrals, and what they are worth
Your link is on the Referrals page. Anyone who signs up through it becomes your referral.
What they are worth to you:
A share of what they earn — 15% on a free account, rising to 30% on Pro. It is added to your balance, never taken out of theirs.
Faster delivery. One active referral is one of only two things that moves your campaigns up the queue.
A way up the ranks. A referral counts towards your rank once they reach Silver themselves.
The same page lists everyone you have referred and how far they have got.
