Did you know Vinefire? This portal is one of media to promote our website directly with earnings based on three categories: add link, click on the links and referrals. Unfortunately, Vinefire is not online anymore now.
If you are still looking for similar sites, this one may be very useful. Its name is Live Link Cafe. The system is similar to Vinefire, do not provide earnings in the form of money, but a certain number of "views" towards a "post points" which allows you to add your own link to the system. Every 10 link views you will earn 1 live link named a "post points", and you will get 50 free live links/post points from referral.
