I've got a demo domain for some websites that I'm putting together - each site will go in its own directory...
www dot demowebsite.com/site1
www dot demowebsite.com/site2 etc.
Once a site is ready to go live I'll delete it from the demo domain and put it live on its own domain.
My question is: will this give me duplicate content issues with Google?
If the answer is yes... can I simply de-index the domain and block all robots with robots.txt to prevent and problems?
