Link Bait - The idea is to create page that is so entertaining or informative that others will naturally want to link to it. This can also be a game or online application. The "trick" is, you must get traffic to it in the first place.

One way is to buy traffic from StumbleUpon for 5 cents each at:
http://www.stumbleupon.com/ads/

Send this traffic to your best link bait pages. As people see your page, and if it's good, they will "Stumble" it and your page can be included in the rotation. This will create FREE traffic for you site and traffic.
