A pingback is one of four types of linkback methods for Web authors to request notification when somebody links to one of their documents. This enables authors to keep track of who is linking to, or referring to their articles. Some weblog software and content management systems, such as WordPress, Movable Type, Serendipity, and Telligent Community, support automatic pingbacks where all the links in a published article can be pinged when the article is published. Other content management systems, such as Drupal and Joomla, support pingbacks through the use of addons or extensions. Essentially, a pingback is an XML-RPC request (not to be confused with an ICMP ping) sent from Site A to Site B, when an author of the blog at Site A writes a post that links to Site B. The request includes the URI of the linking page. When Site B receives the notification signal, it automatically goes back to Site A checking for the existence of a live incoming link. If that link exists, the pingback is recorded successfully. This makes pingbacks less prone to spam than trackbacks. Pingback-enabled resources must either use an X-Pingback header or contain a element to the XML-RPC script.

Webmention, a modern re-implementation of Pingback using HTTP and x-www-urlencoded POST data. Linkback, the suite of protocols that allows websites to manually and automatically link to one another. Refback, a similar protocol but easier than pingbacks since the site originating the link doesn't have to be capable of sending a pingback. Trackback, a similar protocol but more prone to spam.
