How to stop /feed/ folder in WordPress from indexing by Google?

Firstly, you just do not have to do that (unless you are a website with a couple of millions sessions per month).

Secondly, you have to ask yourself: Am I optimizing too much? Am I doing the work I need to do?

Thirdly, if you are not agree with previous statements and still want to make in “noidexable” by search systems.

To stop the /feed/ folder in WordPress from being indexed by Google, you can use one of several methods:

1. Using the robots.txt file:

• Log in to your website’s root directory
• Create a file called “robots.txt”
• Add the following line to the file: User-agent: * Disallow: /feed/
• Save and upload the file to your website’s root directory

2. Using the .htaccess file:

• Log in to your website’s root directory
• Locate the .htaccess file
• Add the following line to the file: RedirectMatch 404 /feed/$
• Save and upload the file to your website’s root directory

3. Using Nginx configuration file:

• Log in to your server via SSH
• Locate the Nginx configuration file
• Add the following line within the server block: location = /feed/ { return 404; }
• Save and close the file
• Restart Nginx

Note: Make sure to test your website after making any changes to ensure it is still functioning properly.
