Facebook
Facebook is considered by many as the home of the social web.
Hundreds of millions of people have signed-up to the website, which through its process of continuous development offers more and more functionality and applications to keep its users interested.
Facebook is the number one website for emotional engagement, the perfect platform for building awareness for organisations of all sizes.
What's key to success on Facebook is to find friends with high 'social networking potential'.
It also has a sophisticated pay per click platform, which allows incredibly detailed targeting - down to city, company and even hobby level.
