Editing Trackback

{{Short description|Type of linkback method for Web authors}}
A '''trackback''' allows one website to notify another about an update.<ref>{{Cite web|url=https://www.chrisg.com/what-are-trackbacks-and-how-do-i-use-them/|title=What Are Trackbacks and How Do I Use Them?|date=March 27, 2007}}</ref> It is one of four types of [[linkback]] methods for [[website]] authors to request notification when somebody [[hyperlink|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 [[pingback]]s where all the links in a published article can be [[ping (blogging)|ping]]ed when the article is published.  The term is used colloquially for any kind of linkback.

==History==
The TrackBack specification was created by [[Six Apart]], which first implemented it in its  [[Movable Type]] blogging software in August 2002.<ref>{{Cite web|url=https://movabletype.org/documentation/trackback/specification.html|title=MovableType.org – Documentation: TrackBack Specification|website=movabletype.org}}</ref> The TrackBack has since been implemented in most other blogging tools. Six Apart started a working group in February 2006 to improve the Trackback protocol with the goal to eventually have it approved as an Internet standard by the [[IETF]].  One notable blogging service that does not support trackback is [[Blogger (service)|Blogger]].  Instead, Blogger provides "backlinks",<ref>{{Cite web|url=http://www.consumingexperience.com/2005/10/blogger-backlinks-feature-not-quite.html|title=Blogger: backlinks feature (not quite trackback) - A Consuming Experience}}</ref> which allow users to employ Google's search infrastructure to show links between blog entries.

==Function==
A trackback is an acknowledgment. This acknowledgment is sent via a network signal ([[XML-RPC]] [[Ping (blogging)|ping]]) from the originating site to the receiving site. The receptor often publishes a link back to the originator indicating its worthiness.  Trackback requires both sites to be trackback-enabled in order to establish this communication.

Trackbacks are used primarily to facilitate communication between [[blog]]s; if a blogger writes a new entry commenting on, or referring to, an entry found at another blog, and both [[Weblog software|blogging tools]] support the TrackBack protocol, then the commenting blogger can notify the other blog with a "TrackBack [[Ping (blogging)|ping]]"; the receiving blog will typically display summaries of, and links to, all the commenting entries below the original entry. This allows for conversations spanning several blogs that readers can easily follow.

==Software support==
[[Blogging software]] that supports the TrackBack protocol displays a "TrackBack [[Uniform Resource Locator|URL]]" with every entry. This URL is used by the commenting blogger, whose software will send [[XML]]-formatted information about the new entry to this URL. Some blogging tools are able to discover these TrackBack URLs automatically, others require the commenting blogger to enter them manually.

==Spam==
{{main|Sping}}
Some individuals or companies have abused the TrackBack feature to insert [[Link spam|spam links]] on some blogs.  This is similar to [[spam in blogs|comment spam]] but avoids some of the safeguards designed to stop the latter practice.  As a result, TrackBack [[spam filter]]s similar to those implemented against comment spam now exist in many weblog publishing systems. Many blogs have stopped using trackbacks because dealing with spam became too much of a burden.{{citation needed|date=September 2011}}
