WordPress, by default, includes a simple robots.txt file that’s dynamically generated from within the WP application. This is great, but how do you easily change the content?
Enter WP Robots Txt, a plugin that adds an additional field to the “Reading” admin page where you can do just that. No manual coding or file editing required!
Simply visit https://your-site.com/wp-admin/options-reading.php and you can control the contents of your https://your-site.com/robots.txt

WP Robots Txt

WP Robots Txt Allows you to edit the content of your robots.txt file.

Overview:
At the time of this writing, the latest version of WordPress, version 4.7, 
 has functionality to discourage search engines from indexing the whole site, 
 but not functionality to discourage search engines from indexing only certain 
 specific pages and posts of the site.
Robots Meta Whiz is a WordPress plugin that allows site administrators to 
 deploy custom meta robots tags to discourage search engines from indexing, 
 following links from, caching, indexing images from, and / or have 
 additional custom restrictions on only for certain specifically-designated 
 pages and posts.
It is an easy way to discourage search engines from indexing only specific 
 pages / posts.
This only applies to search engine robots, and will not effect the site’s 
 local search functionality.
Technical summary:
Plugin works by hooking-in special logic into the action ‘wp_head’ to inject 
 the tag <code><meta name='robots' content='...'></code> with restriction directives for 
 the specified pages and posts.
