Everyone knows that the way to earn in PTC sites is to have direct referrals. You can rent referrals but directs are best because, of course, they don't cost you anything if you advertise using free methods. I just found a new program today where you can earn referrals.
Get Ref has many ways for you to earn credits which you can then use to get referrals. Check it out

You can also rent referrals but you have to manage them well in order for them to make you money rather than cost you money.
You can create a blog page with your PTC programs on it and advertise it in the Traffic Exchanges and Safelists.
Post your blog on FB, Twitter, ect.
