As a bare minimum, follow the Website Award criteria. Not only will you be in the running for the award, but you also have a good set of guidelines for building a website that other people will want to see.
Everything that has already been mentioned is good. I would add...
-A small amount of information on your team structure (such as what your sub-groups are)
-If there's anything that is unique to your team - such as interesting mascots, logos, WFFAs, etc - you should probably include a little information on that. We have a
page about the history of our logo, which is something that a lot of people know us by and ask questions about. It's a page that I link to a lot when I get questions about it online.
-Be sure to recognize your sponsors!
