Pingback
Pingback is a method for Web authors to request notification when somebody links to one of their documents, allowing users to keep track of who is linking to their articles.
Services such as Pingoat and Ping-o-Matic notify a number of services that keep track of blogs and publish them.
Some blogging software, such as WordPress, support automatic pingbacks where all of the links in an article can be pinged when it is published. Additionally, these programs can be configured to ping services such as Pingoat or Ping-o-Matic.
