The trick is to find out more about your visitors. One way of doing it is by setting up a small poll or survey booth on your site. What you want to know is what they are interested in. Once you've gathered the answers, set up affiliate products (links) that address their needs.
That should generate "some" additional revenue for you. Keep up the good work. Getting unique visitors is a big accomplishment considering the 54M domain names out there.
