what is referral exchange in the world of PTC and GPT?

Tweet

I'm fairly new to the PTC (Paid to click) world and one of the terms that is often used is "referral exchange". What is it by the way? As i understand it is exchange referral links. The kind like you sign up for one ptc or gpt as my referral and i'll sign up as your referral. Right? Please correct me if i'm wrong. Well, thats what i've been trying to do for the past two days and i haven't been able to sign up anyone as my referral. If anyone knows the trick to do it, please let me know. I signed up with earnmoneyspace.com so i can meet up with people who can be potentially be my referrals. I'm just going to be patient and keep on plucking away. If anyone wants to exchange referral links, please respond or pm me. I would glad to exchange with anyone on here. All the PTCs that i signed up with are in my profile page. Aight
