Contest Link Bait
An exceptional method that can be used as link bait is holding contests. I once ran a contest where I promised to give my income away to anyone who could guess it. They actually had to guess within a dollar.
Quite a few people took me up on the offer. In order to enter the contest, they needed to create a post on their site, linking back to mine using my anchor text, and the number they were using to guess.
Within about 1 week, 70 or eighty people had taken me up on the offer. It worked out great for me, and in reality none of the people guessed that close. As an offer of goodwill, I gave some money to the person that guessed the closest. I think it was like $60 or something. Truth be told, I didn’t really need to pay it but wanted to.
The moral of the story is that contests can be used to create massive amounts of links.
