Just having a website up on the Internet is not enough. When you first put a website its like being on an island because nobody knows about you. Once you put up a website and I would suggest using the Wordpress platform as it ranks the best in Google, Yahoo, and Bing/MSN you'll need to get traffic.
There are two ways to get traffic in the beginning one is organic through search engine optimization and the second is through PPC (pay per click). Once you have the traffic then you can monetize your site by writing articles and promoting affiliate products are do a review website and promote affiliate products. You can find affiliate products to promote at Clickbank. Just do a search in Google and go to Clickbank's marketplace.
