Create a quiz and offer it on your site.

Think about creating a quiz, survey or test that could be interesting to your visitors and is related to your topic.
To make your quiz or test viral, offer people the button code to place your button on their site.
Mention it everywhere you have created accounts: on microblogging sites, social news sites, social networks, etc. to spread the news and circulate it on the Web.
