I've never considered this as a good practice, but is there any benefit to submitting a press release to one PR source, then going to other PR sources and submitting the same content? My main goal, currently on one project, is the soul purpose of link building and backlinking.
I see this as duplicate content, although I am seeing competitors submitting the same press release multiple times trying to reap some sort of benefit from it. In my honest opinion, I would rather submit 1 different press release each week throughout the course of a month to a quality site like PRLog or PRweb.
Comments? Opinions? I would really like to hear them.
