Facebook reportedly gets 22% of worldwide internet traffic. Advertising your service or business through Facebook website may give very good leads. Here is the detailed procedure of how to get those ad coupons worth $350 for free,

> Create a Facebook account if you do not have one already.
> Login to your Facebook account, then click the “Advertising” link from the bottom of the page. Create an ad and later you’ll able to change the daily budget and CPC. You’ll need a credit card here in order to confirm your account, but the charge here is only to confirm space on your account; any temporary hold will be reversed and your advertising will draw from your coupons completely before charging your card.
> After creating the advertising account and getting the “Congratulations Message”, click “Billing” > Click “Funding Sources” > Click “Enter Coupon Code”
> Enter these coupon codes one at a time. Enter a coupon and wait for success message, then enter another.
