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 <meta name='robots' content='...'> with restriction directives for
the specified pages and posts.
