How to put links in REFERENCE section?

Can any help me how to post the link in REFERENCE section. There is two option one is to comment and other is using something called trackback. Seen lot of people doing anchor link building over there and getting backlinks.

Need to know this urgent Help Please

Reference section of where? Do you mean just below your post on a blog, or on someone elses.

Yes its just below the post. I have seen it on some other blogs. I am not able to provide link here otherwise you will get to know what I am talking about

You don't place it below your post others do it by trackback, BasiclyBasically it's a signal to let people know there is relevant content on another site.

You can track back on other people's sites like this, but it's not references.

If you are wanting to place references, just write them into the bottom of the post, with links in the format you want.
