<p>When a post is published or updated, Internal Pingback Comments scans its content, finds all internal links, and creates a pingback-style comment on each linked post. It mimics native WordPress pingback behavior but eliminates the need for XML-RPC or outbound network requests.</p>
<p>Works with posts only. No settings page, no configuration.</p>
<p><strong>How it works</strong></p>
<p>The plugin parses post content with DOMDocument — not regex — so it handles real-world HTML correctly: nested tags, encoded entities, relative and protocol-relative URLs. For each internal link found, it inserts a pingback comment on the target post. The comment includes a short excerpt from the source post, with image captions (figcaption) stripped so they do not bleed into the pingback text.</p>
<p>Duplicate detection is precise: the source permalink is stored as private comment meta, and the plugin queries that meta before every insert. Republishing or updating a post never creates duplicate comments. New links added to an existing post will generate their own pingbacks on the next save.</p>
<p><strong>What the pingback looks like to your theme</strong></p>
<p>The comment is stored with <code>comment_type = 'pingback'</code> and auto-approved. Your theme renders it exactly as it would render a native pingback. If your theme does not display pingbacks, the comment will be stored in the database but remain hidden on the front end.</p>

Internal Pingback Comments

Detects internal links in posts and automatically inserts a pingback-style comment on each linked post. No XML-RPC required.

<p>Generates richer WordPress comments from linkbacks such as <a href="https://wordpress.org/plugins/webmention" rel="ugc">Webmention</a> or classic linkback protocols like Trackback or Pingback.</p>
<p>The limited display for trackbacks and linkbacks is replaced by a clean full sentence, such as “Bob mentioned this article on bob.com.” If Bob’s site uses markup that the plugin can interpret, it may add his profile picture or other parts of his page to display as a full comment. It will optionally show collections of profile pictures, known as Facepiles, instead of the full setences.</p>
<p>Semantic Linkbacks uses <a href="http://microformats.org/wiki/microformats2" rel="nofollow ugc">Microformats 2</a> to get information about the linked post and it is highly extensible to also add support for other forms of markup.</p>
<h3>Privacy and Data Collection</h3>
<p>This plugin collects data from sites that send webmentions for the purpose of displaying richer comments on a site. This data is under the control of the site owner. It is the personal responsibility of that individual or individuals to remove any information at the request of the original content creator. Over time, we will add additional tools to assist in doing so.</p>
