If you have specific examples of things you're looking for, let us know. However, here's a few examples of how to get your site more noticed in Facebook:
1) Use the Comment and Like button on your pages. When a user likes or comments on a page, that page will show up in their Facebook Wall, showing your site off to their friends.
2) Use the JFBCFan module if you have a Facebook Fan Page. This let's user's easily see, and like, that page which is good for building a reputation on Facebook itself.
3) Use the ability to post to a user's wall on registration and/or login to put a greeting on their wall when they come to your site.
For the upcoming 4.0 release, we have a few new ways to get your site onto Facebook, and especially in your Facebook Page. That release is coming out in July, and we'll have more information about the features soon.
Hope that helps.
