A WordPress-Plugin for flagging individual pages and/or posts, so they will output a <meta name="robots" content="noindex" /> tag.

This tells the search-engines not to index you page/post.

This plugin is thoroughly tested using PHPUnit.

Go to your WordPress installation directory, then change to wp-content/plugins.

Then either run (the preferred way):

git clone \
https://github.com/superevilmegaco/wp-robots-noindex.git \
-b v3.0.1 \
wp-robots-noindex

or (no easy updating via git or git submodules) download the latest release from here and unzip its contents to wp-content/plugins/wp-robots-noindex.

Then head over to www.your-wordpress-installation-domain.tld/wp-admin/plugins.php and activate the plugin.

If you don't tick the checkbox (this is the default), it'll output a <meta name="robots" content="index,follow"/> tag, which tells the search-engines to index your post/page and follow all the links.

If you happen to have a completely customized theme, you can simply call this function

<?php
        robotsnoindex_display_meta_tag();
?>

This will result in

<meta name="robots" content="index,follow"/>

If neither the Robots: NoIndex, nor the Robots: NoFollow checkboxes have been ticked.

If the Robots: NoIndex checkbox has been checked, but not the Robots: NoFollow checkbox, robotsnoindex_display_meta_tag(); will produce the following output:

<meta name="robots" content="noindex,follow"/>

If the Robots: NoFollow checkbox has been checked, but not the Robots: NoIndex checkbox, robotsnoindex_display_meta_tag(); will produce the following output:

<meta name="robots" content="index,nofollow"/>

If both the Robots: NoFollow and Robots: NoIndex checkboxes have been ticked, robotsnoindex_display_meta_tag(); will produce the following output:

<meta name="robots" content="noindex,nofollow"/>

If you don't want to produce any output, but want to check for the current status of the post, you can simply call robotsnoindex_get().

<?php
$noindex = robotsnoindex_get(ROBOTSNOINDEX_NOINDEX);
$nofollow = robotsnoindex_get(ROBOTSNOINDEX_NOFOLLOW);
if ($noindex) {
        // noindex is set for this post/page
} else {
        // noindex is NOT set for this post/page
}
if ($nofollow) {
        // nofollow is set for this post/page
} else {
        // nofollow is NOT set for this post/page
}
?>
