Can some one explain what "trackbacks" are, what they do and how to use them. Are they a method of getting backlinks?
Basically a post to their post is a trackback. If you track back to someone's post, you will get a link back from them.
Can you go into detail about trackbacks, such as what people think about them. Are they usually moderated heavily? is there often issues where you link to someone and they don't approve the trackback? Or is the trackbacking automatic?
Trackback - (computing) A method to keep track of links to content, especially blog entries; (Internet) A snippet of text joined to an entry from another website linking to it
Had recently read this excellent starter post on trackback - trackback as link exchange I think it's worth a read.
http://en.wikipedia.org/wiki/Trackback I'd suggest you Google questions like this before, I just googled the word "trackback" to find that wiki link.
