30 visitors in the beginning just from directories is pretty good.
If you want to add it to google go to
http://www.google.com/addurl, and in max. 2 weeks you'll be listed there. Or the easier method: if you're already listed in directories, it means you already have backlinks. If the directories are listed in google, google will cache them within some weeks, and their robot will follow the link to Your site aswell, and cache your site, so you'll get listed then.
P.S.: I PMed you about being an admin..
