How do I get advertisers for my website?

I assume your blog is in a certain niche - a topic you are passionate about. As others have already stated, becoming an affiliate would be the best way to go if you want to earn money from it. A popular affiliate market place is clickbank. Just head over there and search for products to promote in your niche.

I would agree. I would definately go the affiliate route. Its going to be the better way to do it as depending on your listings etc means that people are more likely, or less likely to actually pay to be on your site. Try the affiliate route, and see how you go. Most blogs have the ability to "add" this actually to your blog!
