How to promote a news website - Advices needed


I run a news website, just like Tribune and Thenewstribe, and I've created its page on facebook as well, to get visitors from there.. I wanted to promote the page using facebook page boosting service but it was not accepting debit card, it said "invalid" for my Askari Bank's Debit Card -- Any idea how to use it there?

So back on topic, how to promote the website, software I am using is wordpress of course as its the best. So please give advices.

Thanks.. :)
