With the recent news that Facebook now has 2 billion users, it is a given that it is the greenest pasture for marketing. Making it more convenient for marketers is the Facebook Page that you can create for free and you can use for your own purpose, not for illegal ways though. If you have a business, you can put everything on that Facebook Page, your product or service, your address, of course, and the details like costing and arrangements of delivery. When you post the link of that Page onto your timeline then all your friends can see that advertisement. Isn't it convenient and simple?
