  Neeraj Kumar: Now +Steve Bonin after your reply, is it possible that while developing a site and uploading on server for trial, a website could not be crawled!

  Steve Bonin: +Neeraj Kumar ;I usually upload to a sub directory on my hosting server (BlueHost) then transfer to client domain/hosting when the project is finished at which point I submit a sitemap to WMT.  ;It is possible that the site will be crawled while sitting on my server but not likely.
