A trackback URL is where somebody posts a link to their site on your site. In return, they have posted a link to your site on their site and have copied an article you have written.

A trackback is an automatic process of notifying a blog that enables authors to remain track of who is linking to their articles. When another blog is being referenced in a blog post, the trackback field can be used to start a process that 'pings' the other blog, alerting it to the external link.

A trackback is an automatic method of informing a blog that you’ve linked to an article. When another blog is being referenced in a blog post, the trackback field can be used to begin a process that 'pings' the other blog, alerting it to the back link.
