trackback
Synonym discussion
Sense: noun/1
All three words describe ways that one website points to another, but they differ in how the connection is made and how automatic it is. A trackback is an automated notification that a blogging platform sends when one post links to another; it requires the receiving blog to support the trackback protocol. A pingback works similarly but uses XML-RPC technology and tends to be more reliable. A backlink is any incoming link to a webpage, regardless of whether it was sent automatically or added manually. For example, a Wikipedia citation creates a backlink but does not send a trackback or pingback. In practice, many modern blogs have replaced trackbacks with pingbacks or social-media sharing buttons.

Etymology
A compound of 'track' (to follow the path of something) and 'back' (returning to an earlier point). The term was coined in 2002 by Six Apart, the company behind the Movable Type blogging platform, as the name for their TrackBack specification. It describes the system's core function — tracking links back from one blog post to another.
