{{Short description|Type of linkback method for Web authors}} {{Use dmy dates|date=May 2026}}

A '''trackback''' is a linkback method used to notify a website when another site links to its content.<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 enables websites to display links and excerpts from referring posts, allowing discussions to span multiple websites.<ref name="mtbeginners">{{Cite web|url=https://movabletype.org/documentation/trackback/beginners/|title=A Beginner's Guide to TrackBack|website=MovableType.org|access-date=2026-05-29}}</ref>

==History== The TrackBack specification was created by Six Apart, which first implemented it in its Movable Type blogging software in August 2002.<ref name="mtspec">{{Cite web|url=https://movabletype.org/documentation/trackback/specification.html|title=MovableType.org – Documentation: TrackBack Specification|website=movabletype.org}}</ref> Released as an open specification, the protocol was subsequently adopted by various other content management systems. A revised specification (version 1.2) was published in 2004.<ref>{{Cite web|url=http://archive.cweiske.de/trackback/trackback-1.2.html|title=Trackback Specification 1.2|date=August 1, 2004}}</ref>

Some platforms used alternative systems instead of TrackBack; for example, Google's Blogger implemented a proprietary "backlinks" feature based on Google's search infrastructure.<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>

==Mechanism== A trackback works by sending an XML-RPC ping from the originating site to the receiving site's TrackBack URL. When an article is published, the blogging software sends an HTTP POST request containing the source URL, the entry title, a short text excerpt, and the name of the blog.<ref name="mtspec"/>

Some platforms discover TrackBack URLs automatically through HTML metadata, while others require authors to enter them manually. The receiving platform may then display the reference alongside the original entry, allowing readers to follow conversations across separate websites.

==Spam== {{main|Sping}} Because trackbacks publish user-submitted URLs without prior authentication, the system became a major target for link spam. Spammers used the protocol to post automated backlinks to improve their search engine optimization rankings.<ref name="bursztein"/><ref>{{Cite web |title=Why Backlinks Matter for SEO and Page Rank|url=https://www.wikibusines.com/wikipedia-backlinks-power|access-date=2026-05-29|website=WBusines}}</ref> A 2009 Stanford University study analyzed a single campaign that generated nearly 10 million TrackBack spam pings in a year, demonstrating the vulnerability of the protocol.<ref name="bursztein">{{Cite conference|last1=Bursztein|first1=Elie|title=TrackBack Spam: Abuse and Prevention|conference=ACM Workshop on Cloud Computing Security (CCSW '09)|year=2009|publisher=ACM|doi=10.1145/1655008.1655011|url=http://theory.stanford.edu/people/jcm/papers/blogspam_CCSW09.pdf}}</ref> Anti-spam filters and automated detection methods were developed to stop this abuse,<ref>{{Cite journal |last=Kimura |first=Masahiro |date=2005 |title=Detecting Search Engine Spam from a Trackback Network in Blogspace |journal=Knowledge-Based Intelligent Information and Engineering Systems |pages=723–729 |doi=10.1007/11554028_101}}</ref> but the volume of spam made trackbacks too difficult to maintain. By the 2010s, most platforms disabled trackbacks by default or removed them entirely in favor of pingback or Webmention.<ref name="bursztein" /><ref>{{Cite web |url=https://www.wpbeginner.com/beginners-guide/what-why-and-how-tos-of-trackbacks-and-pingbacks-in-wordpress/ |title=What, Why, and How-To's of Trackbacks and Pingbacks in WordPress |website=WPBeginner }}</ref>
