The most basic thing you can do on Facebook to promote your business is to create a page, which also serve to create and expand a network, connect with them, and more.
To go further there are applications or “apps”, programs that work as accessories created by people outside of Facebook that are incorporated into your account so you can take care of increased business from one location.
My BusinessBlinkWeb This app is fantastic, is used to create a “widget” or a plate to promote your business. Facebook users then can add your widget to their profiles. This means free advertising in your network.
IEndorse is an app that lets your Facebook contacts leave “endorsements” or positive testimonials about your business on your site. By adding this app, users can find you through an additional channel: the database IEndorse business. And if you have a personal profile and you want to create a separate profile for your business, you can do with this app. (Testimonials offers the same but does not include a database.)
Introductions good if you are a shy person (even in the virtual world) or you can not think exactly how to present a contact that you are interested. Also for you you start presentations from your contacts and your contacts will help create useful connections.
