There are a lot of reasons why Google might not be listing your site. Once you submit your site it can take months to show up, if at all.
Here are a few simple things that Google likes that will help you get listed.
Google likes a good clean straightforward site. Good clean code and logical navigation is essential to allow any search engine spider to search your entire site. Validate your code and clean up any errors.
Make sure that the page your are submitting has substance to it. Google cannot index what is not there. A doorway page or a flash page won’t give the Googlebot much to work with.
Get other teams or sites to link to you. Google likes sites that other sites want to link to. A good place to start is with your sponsors. When Google visits their sites, then the Googlebot will follow the links to your site. Submit your site to the ODP Open Directory Project. They have a section for FIRST teams.

Check your robots.txt file for the correct syntax. If you don’t have one, then put one up. It’s considered proper form to have one. Googlebot will be looking for it.
Add new content often and make small changes to your index page at regular intervals.
