A trackback is a feature on blogs that allows people to “trackback” to specific posts. When someone clicks on a trackback link, they are taken to the post they are tracking back from.
This is helpful for readers who want to follow a series of posts, or for bloggers who want to keep track of what their readers are saying about their posts.
The advantage of using trackbacks is that it allows bloggers to keep track of which posts are being read the most. If a post is getting a lot of traffic, it may be worth re-posting it with a link to the trackback so that people can continue following the discussion.
A disadvantage of trackbacks is that they can be difficult to set up and use. Some blogs have built-in trackbacks, while others require the blogger to add a special code to their post.
If you want your blog post to be included in a blogroll or in search engine results, you will need to include a link to the trackback in your article.
