What is "trackback"

n. 1 (context uncountable computing English) A method to keep track of links to content, especially blog entry. 2 (context countable Internet English) A snippet of text joined to an entry from another website linking to it.

A trackback allows one website to notify another about an update. It is one of four types of linkback methods for website authors to request notification when somebody links to one of their documents. This enables authors to keep track of who is linking to their articles. Some weblog software, such as SilverStripe, WordPress, Drupal, and Movable Type, supports automatic pingbacks where all the links in a published article can be pinged when the article is published. The term is used colloquially for any kind of linkback.
