Lots of good advice. Even if you are using a comparison script you can still change the look of your site. I would spend a bit of time or money to make it look more professional. Secondly I would add some unique content to the site, this will bring in more Google traffic. You can also submit unique articles to ezinearticles (yes there are other article directories but ezinearticles works). Get links to your site. Just browse this forum and there are hundreds of ways to do this, it all requires a lot of work though.
Try putting your link on directories. Or paying owners of popular blogs to have a small promotion of your site on their blogs.
