Facebook is not for college students anymore. Many businesses are taking advantage of the exposure (either locally or not) that facebook can prvide their business. You can create a free page about your business, a group to offer real estate advise or share a common interest, post free market place listings - and much more.
The most important real estate in Facebook. This is the first page people will see when they stumble upon you.
Fill out the entire profile, be authentic, show off your talents, hobbies, brand and share your story for everyone to see
Pages were launched by Facebook in November 2007 as a way for businesses of many types to easily establish a brand presence on Facebook. Consider them a profile for your brand or service.
Mini Feed and News Feed
Whenever you do "something" in Facebook it gets posted in your feed. Change your profile, and your friends will see a post, add an application and your friends will be able to read about it.
You can create groups or participate in groups related to your industry. Creating a group gives you control over the "profile" of that group, the posts and most of the content.
A Facebook application that allows you to announce and promote any event you are having
Notes and Photos
Share blog posts (you can import your own blog feed).
Create a photo album and be sure to use the TAG feature and list any friends in the photo that have facebook profiles.
Much like email (only limited) Messages allow you to send notes to people you are connected to. Actually you can send a note to people you are not connected to, but be warned - you do not want to be flagged for spamming.
Facebook Classifieds. You can post items for sale, services offered, job openings, etc.
Ads appear in your network only - and again, do not get "spammy" that will get you banned.
Share / Posted Items
Create links to Facebook pages, photos, events, etc...
When you join Facebook you have the option of becoming the member of a Network. Networks can be geographical (Albany, NY) or educational (S.U.N.Y. Albany)
