Ever have this problem? Your staging site accidentally gets listed in Google’s search results. This is very bad for many reasons. The first reason is the fear of being penalized for duplicate content once the production site goes live. Second, it’s really embarrassing when the client Googles themselves and sees the staging site in the results. Generally, the staging server should only be viewed by the developers and the client. Unfortunately, that doesn’t always happen because the staging site wasn’t properly blocking Google, resulting in the site being listed in Google.
