WordPress SEO nofollow

Javier Casares

Fine-grained control over how search engines index and display your WordPress content. Apply 5 independent robots directives to 25 different page contexts with flexible implementation methods.
5 Robots Directives:
<ul>
<li>noindex: Prevent search engines from indexing the page</li>
<li>nofollow: Prevent search engines from following links on the page</li>
<li>noarchive: Prevent search engines from showing cached versions</li>
<li>nosnippet: Prevent search engines from showing text snippets in results</li>
<li>noimageindex: Prevent search engines from indexing images on the page</li>
</ul>
Implementation Methods:
<ul>
<li>HTML Meta Tags: Traditional method, easy to verify in page source (default)</li>
<li>HTTP Headers: More robust, works with all content types including PDFs and images</li>
<li>Both: Maximum compatibility for all scenarios</li>
</ul>
Control Levels:
<ul>
<li>Global Settings: Apply directives to 25 different page contexts (posts, pages, archives, etc.)</li>
<li>Granular Control (Optional): Override global settings for individual posts, pages, and custom post types via meta boxes in the editor</li>
</ul>
Perfect for:
<ul>
<li>Blocking indexing of attachment pages while allowing link following</li>
<li>Preventing duplicate content issues with flexible directive combinations</li>
<li>Controlling archive page indexing with granular control</li>
<li>Managing pagination SEO with independent settings</li>
<li>Protecting private content from search engine caching</li>
<li>Preventing snippet display while still indexing content</li>
</ul>
