I keep seeing on Pligg sites and such where you can submit links that it has a field for trackback links. I always leave this blank, but is it significant in any way and should I be submitting a URL into this field?
you have to put a url of an article you are adding on to and if the owner of that blog approves a snippet with a link will be on his site back to yours
But if you don't, then the trackback just becomes the URL that you submitted your blog entry to - isn't this a little strange? Theoretically you should just have a trackback link be to the root of your website and gain another backlink from websites
