How to Block Indexing done by Search Engines (Internal)
A client may be concerned that someone such as a competitor could use Google alerts or other methods to monitor their domain and would like to block search engines from indexing their referral site.
We've not known Google or other search engines to list customer sites before and we don't have any specific logic that would cause them to be listed. We can however, if they are worried, add custom <meta> tags to their customer site pages which specifically tell search engines not to index in the advanced section of the program editor (Page > Advanced HTML inject).
A screenshot of the proper tag is below. Reference this article for further information.
