To help your WordPress installation be more optimized for search engines, this plugin will include a ‘noindex’ meta tag in the header of any duplicate posts. 
Robots will not index any posts with matching title tags, which is a known indicator of negative SEO. This is very useful for automated posting and working with a large amount of posts.

Noindex Duplicate Posts

This plugin will automatically add a 'Noindex' meta tag to posts that are a duplicate determined by the slug and preexisting post names.

This plugin is now part of <a href="https://wordpress.org/plugins/native-aeo-pack/" rel="ugc">Visibility</a>.
Everything this plugin does is bundled into Visibility, a single lightweight 
plugin that unifies the three AyudaWP “Native SEO” plugins (Meta Tags, NoIndexer 
and Sitemap Customizer) into one, built entirely on WordPress native features.
This plugin still works and stays available, but new features and fixes now go 
into Visibility. If you’re setting up a new site, install Visibility 
instead of this one.
<h4>Moving to Visibility</h4>
<ol>
<li>Install and activate Visibility.</li>
<li>Open its settings, enable the modules you need (Meta Tags, NoIndex, Sitemap) 
and set your site-wide options.</li>
<li>Deactivate this plugin. Visibility reminds you while both are active, 
because running both at once prints duplicate tags.</li>
<li>Check your page source: you should see a single set of tags, from Visibility.</li>
</ol>
Your settings are not imported automatically in this first version. Site-wide 
options take a minute to re-enter. For per-post values (individual noindex/nofollow, 
custom titles and descriptions, Open Graph images), deactivate this plugin rather 
than deleting it, so the data stays in place for the automatic importer planned 
for a future Visibility release.
