Another way to get more traffic to your site is to trade eyeballs. Because the Web is all about linking and surfing, there is a good chance that some of the other site's visitors will come your way, and vice versa. In the course of your own Web browsing, keep your eyes open for sites that are compatible with yours. When you see a good fit, look around on the site for an e-mail link to the Webmaster, then drop him or her a note. Include the URL of your site and an invitation to exchange links.
Personal sites are probably a better bet than commercial sites.
These Webmasters get less mail, so yours stands out. And like you, they're doing it mostly for fun. For wider coverage than you can get from a single link exchange, try a Web ring, a linked group of sites devoted to the same subject. Each site displays a logo and links to other sites in the ring, and to the ring's home page. There are dozens or perhaps hundreds of Web rings already in existence.
