The difference between Linksert and all the other affiliate-marketing sites is that Linksert is super easy to use and they have a load of partners (over 18000).
The registration through Facebook or Twitter is as simple as it can be. After registration you can shorten/convert every Link you want into affiliate links. The converted links can be shared wherever you want. Even the smallest Blog, Website or Facebook group can make money with it. Of course all services are free.
