"Like it" only this but so much
Everybody knows what "Like it" means on Facebook. Not everybody realizes how important it can be. Thanks to Facebook campaigns we can increase the number of "Like it" and raise interest in our company.
Own applications and systems
Facebook also allows you to implement own applications. We can e.g. add own products searchers, new promotions, news system etc. All applications are managed by own system but Facebook is only medium to forward information.
