Linkback

This enables authors to keep track of who is linking to, or referring to, their articles.

The four methods (refback, trackback, pingback and webmention) differ in how they accomplish this task.

"Linkback" is the generalized term used to reference four methods of communication between websites.

While sometimes confused with one another, linkbacks and backlinks are not the same type of entity.

Any of the four terms—linkback, trackback, pingback, or (rarely) refback—might also refer colloquially to items within a section upon the linked page that display the received notifications, usually along with a reciprocal link; trackback is used most often for this purpose.
