trackback
A trackback is a mechanism used in blogging and other content management systems to notify other websites when you link to their content. It functions as a notification system that alerts the original author of a post that someone has referenced their work. When a user publishes a post that includes a link to another blog post, they can send a trackback to the original post. This trackback contains information about the linking post, such as its title, a snippet of its content, and a URL to the post itself. The receiving blog then displays these trackbacks, often in a dedicated section, allowing readers to see which other sites are discussing or referencing the same topic.
Trackbacks were designed to facilitate a more interconnected web of online discussions, enabling conversations to flow
