You can use trackbacks to notify other blogs about your post. You would normally make a trackback to a post that you have quoted from, or make reference to. Your trackback will appear on the referenced blog post, allowing readers to see your post as well. This is a good way to allow people to discover your blog by reading other blogs.
Separate different trackback permalink addresses with a new line.
If your trackback is successful, you will see the domain of the trackback added onto to the content of your post.
You can then delete this added-on content if you wish.
A failed trackback will not append anything.
