<p>This simple and lightweight plugin adds a “Hide from search engines” checkbox above the publish box to pages. By<br />
ticking this box, a meta tag will be placed into the <code><head></code> section of your page specifying that robots should<br />
not index the page.</p>
<p>By default this only applies to pages. You may extend this functionality to posts or other custom post types with a small bit of code. See the FAQ’s tab for further instructions.</p>


Noindex Pages

Ask search engines not to index individual pages by checking an option in the publish post box.
