In order to make this plugin work, you need 2 thing:

</li>
<li>
The Google identifier of your domain, that’s the value of your _utma cookie on your website. Yo find this, use Mozilla Firefox (Tools>> Options>>> Show Cookies). Find your site, expand and look for the cookie named “_utma” (look at the first screenshot).
</li>
</ol>
Once you have this informations, you can install and activate the plugin.

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.
