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.
Works with posts only. No settings page, no configuration.
How it works
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.
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.
What the pingback looks like to your theme
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.

Some people really like that WordPress sends pings from your own site to your own site when you write posts; it gives them a trail of related posts.
Some people do not like this behavior; it clutters up their comments.
This plugin disables intra-blog pinging.
Once activated, there’s nothing for you to do. However, head to Settings -> Discussion and you’ll find a field in which you can, if you wish, specify more domains that won’t be pinged. Why? Well, maybe you often refer to other sites that you maintain or, particularly, you run a multi-site and don’t want each blog pinging the other – specify a list here and you’re sorted.
