I stop surfing the site. Join just one banner exchange, and display 1 banner per page. After all, the point is not just to attract people to you site - you want them to wander around it. The fourth, least understood, and most powerful technique for promoting your website is Reciprocal Links. Try to get similar websites to link to you, and in return give them a link back.
Many people are afraid to link to other similar sites.
This is a mistake. What this does is ask the browser to open the new URL in a new window. Your site is still visible in the old window, so your visitor has never really left you. You'll feel more secure and confident, knowing your website has been well promoted. And, since everyone knows that confidence is sexy, there's a good chance your sex life will improve.
