Text Link sales
This is probably one of the easiest ways to make money online, Internet Marketing Tools give you the resources you need and all you have to do is go to popular forums and let people pay you to place their link on your site. All you have to do is announce that you're selling them on a forum and place a link. As soon as you have somewhat good traffic people will want to pay for a place on your website.

Banner ads
This is another easy way of making money with your website youdo the same thing as above. You can announce that you are looking for ad sponsors for your website over a forum and you can get paid loads of money for this, I heard of some people getting paid 10K for one banner. Imagine if you had around five on you website.

Paid Reviews
Now this is something you need to try out, its very easy and you can get paid a lot of money for it! All you need to do is sign up for a review site. You can then have people review your site, and then place those reviews on your website. Ive been paid 200 dollars for one single review. Talk about a profitable way to make money! Here are 4 great networks in which you can do paid reviews.
