Learn how to use the pingback rel link tag to improve your site.

The pingback link rel tag is used to automatically notify the author of a document when another document links to it. It is part of the XML-RPC specification and enables websites to communicate about links in an automated fashion.

Code Examples

<link rel="pingback" href="https://example.com/xmlrpc.php">
Correctly specifies the URL to the pingback endpoint.
<link rel="pingback" href="/xmlrpc.php">
Uses a relative URL for the pingback endpoint, which may lead to incorrect URL resolution.


  • Verify Endpoint URL
    Ensure the pingback endpoint URL is correct and responds to XML-RPC requests; a wrong endpoint can lead to failed notifications.
  • Avoid Using Both Pingback and Webmention
    Using both pingback and webmention tags can lead to duplicate notifications. Prefer webmentions as they are a modern, simpler alternative.
