I have been blocking all IPs to my website (except my own) while it is in development.But now I am at a point, where I want other people to be able to see it, but I still don't want googlebot on it until it is finished.  I just have too many competitors, and I don't want them catching wind of what I'm working on.  Many of them use google alerts.Is it harmful to block google while I continue to build content?  I would prefer to make it available to Google when it is more developed.  On the other hand, I want to start working on Google+, Facebook, Webmaster tools, and Google analytics now.Would that cause trouble down the road in the almighty eyes of Google?
