Welcome to the Q&A Forum

I'm starting a new SEO project and am feeling a little overwhelmed due to the scale of it. I am not sure where to start and hope that someone has some ideas. Thousands of dealer websites reside as sub domains on gravelymower.com/ (e.g. http://quality-mowers.gravelymower.com/) The particular sub domain mentioned above is not showing up at all for any searches and is not cached by Google: http://webcache.googleusercontent.com/search?q=cache:http://quality-mowers.gravelymower.com/ I realize that pretty much zero SEO best practices are followed on page and the location is not on the page, but why is this sub domain not even being indexed by Google? Any help is appreciated. Thanks!
