What are the best ways to increase your site's position in Google?
I have recently finished one of my side projects. Now many sites have things like robot.txts (probably not the best file to describe what i need but you get what I mean) and things of that nature not totally sure what else there is but things behind the scenes that sites use to identify themselves to things like google, yahoo, and bing(but I could have just said google! zing!)
I was wondering, what I needed to add to my site for it to be fully web compliant and searchable and proper. I am basically looking for best practices.
