TrackBack is a system implemented by many blogging tools, including Movable Type and WordPress, that allows a blogger to see who has seen the original post and has written another entry concerning it. The system works by sending a 'ping' between the blogs, and therefore providing the alert.

TrackBack typically appears below a blog entry and shows a summary of what has been written on the target blog, together with a URL and the name of the blog.

The specification for TrackBack and its implementation were developed by Six Apart, creators of the MovableType weblog and content management system.
