This post will help redirect all AMP page URLs to original page, post, and category URLs with Redirect plugin in WordPress. I will be using REGEX to implement bulk redirection in WordPress using free plugin.
Install Redirection Plugin
Login to your WordPress admin area and click add new plugin and look for Redirection, install it and activate it if you do not this installed already.
Add New Redirection
Select REGEX on the right and write REGEX code and hit save
This may take some time to implement and you now need to clear the browser cache and you are done, it should start redirecting your amp URLs to original URLs.
