Many people may not do this but I would say, try to make your domain unique. And only use .net if your a network, .org if your a organization. Don't just go the next domains just because there the only available. Try to get a .com if possible because many times when people type in domains, they will type .com.
Also, get a unique name.
Use google. (remember to do SEO)
and probably link exchanging too.
Getting ads on popular sides such as this.
