I am not sure exactly what a pingback is for a blog.
I have received 6 pingback requests on my blog that is a page of my website. Is this something that would be to my benefit if I approved them? The site they they are linking back to has no pagerank, and my blog does have a pagerank.
Please give me any advice or info about pingbacks and if they are useful as far as helping you rankings and such.
Thanks!!
