Is it possible to make over $25,000 in three weeks on Facebook? It certainly is. Brian Campbell did just that in May 2008, and he’s shown people how it can be done. And the techniques he uses apply just as well to other social networking sites, like MySpace, Bebo, Hi5 and LinkedIn.

How exactly did Brian do it? Brian gave away access to a 3 1/2 hour video training session in which he revealed everything he did to make that much money. Here are some of the methods he used:

You need to create a network of contacts. Start with your friends. You can invite between 20 and 30 people a day to become your friend - if you invite too many, Facebook will tell you to slow down. You can find people who are interested in the same things you are by joining groups, and looking through the lists of members.

It’s important to send a personal message to everyone you invite. People are more likely to confirm your request if you let them know that you share a common interest. If it’s someone whose name you recognise, tell them so!

The best way to get friends is by having people invite you to become their friend. You do this by being visible - and being sociable - posting comments, photos and videos on your friends’ profiles, for example. That person’s friends see what you’ve posted, and hopefully ask you to be their friend as well.

Once you’ve built up a few hundred friends, you should start your first group. Invite all your friends to join, and ask them to invite their friends to join as well. Reward people for joining your group by giving them good quality information, in the form of articles, videos and downloads - PDF reports are great.

Your network of contacts will be all the people you can reach - your friends, and the people in your groups. Eventually, you’ll want to start moving people off Facebook and onto your mailing list, so that you can contact them by e-mail.

You can get free access for a limited time only to Brian Campbell’s free training course, the Social Media Monetization System. He’s giving away more than 10 hours of training, which includes the 3 1/2 hour video series in which he explains how he made over $25,000 in 3 weeks on Facebook. Seats are limited, so you’ll need to take action as soon as you can.
