Now I am working on Social Bookmarking. When I add details in social bookmarking, than last option is "Trackback". So, I want to know what is trackback? and How to useful of Trackback?
Trackback means the approved link that you will get after posting your website will link on that url which is the trackback. When you have a post for example and you want it to automatically link on your post, it will appear in your comment system.
