Question

How do I exclude a Help Center page from being indexed by Google? 

Answer 

To temporarily exclude a specific page from being indexed by Google, you can utilize the Remove URLs feature available in your Google Webmasters Tool account. This feature indicates which page should be removed from the Search Engine Results Pages by Google.

You can verify your account with Google Webmasters Tool by adding a meta tag to the Header of the Help Center, as described here. If you wish, you can restrict Google from indexing all the content of your Help Center, by following the steps described here.
