The problem: a page like that is created for each of your posts, resulting in duplicate content and
potential guarantees penalties.
The solution: Easy. Add the following to your robots.txt file, changing the filename where appropriate:
This tells the robots to ignore any content that begins with the string ‘wp-content’ & which includes the Popup. It may take a few
months weeks for Google Crawler to obey your command, but they will and the content will drop out. I disallowed mine today, so I’ll be in a position to judge just how long it takes very soon, I hope. I’ll take a look at the rest of the indexed pages today and probably have some more recommendations for exclusions soon, but for sure this repetitive popup page isn’t needed.
