Whats “Trackback?”
Trackback is a means for one Web page to let another Web page know that it’s been linked to. Confused? Yes. Trackback is one of those things that is hard to understand until you use it. But, once used, it’s potential is quickly realized. Think of Trackback as a way to comment on your blog about another blog’s entry. And, the greatest part is, there should be no extra work on your part. You merely include a link in your blog entry back to the original blog entry you are commenting on, and the Trackback occurs automatically.
