Affiliate Marketing Secrets

and if yes, what is better on your opinion? a fan page? a store?…I dont want a website

Hey guys so you all know about banners, a company makes them and gets affiliates to place them on their sites then when someone from that site clicks on that banner and goes to the companies site any subsequent sale is credited to the advertisers site and he is given a commission.
My question is, is there any way to do this with Facebook?
For example if I simply put a link on my fan page to someone site and then a Facebook fan of mine clicks it and makes a purchase, will it be able to get traced back to me?
Not sure if Im asking this right but you should get the idea. I have offers to advertise on my fan page and will get a commission of any subsequent sales.
Could this work?
How do companies usually track this kind of thing?
Thanks for the help guys 🙂

It has no real niche, it is just a phrase that a lot of people relate to and I have been quite inactive for a long time but am starting to improve the page at the moment. I’m not sure whether I want to sell it but I was just wandering if i wanted to, what a fair price would be for this amount of fans?

I’m starting a web based business for a niche market and am looking for a cheap way to advertize. the site should soon gain international popularity if I can get the word out effectively.
I was thinking something like fb or twitter would be great, though I’m not really social media savvy myself.
The site should be popular among the niche since it’s free and useful.
Any insight?
