I learned something recently. Which possibly most spammers wont know. Press release sites appear be no good for SEO? Let's use an example. Pr web. So if you're spamming press release sites with junk news just for links it is highly likely you are wasting your time. It seems as if the only use to these sites, especially the piad ones, is to write something that is actually news worthy and hope it gets picked up by other websites so you get some link juice. I also question whether value comes from some of the sites the links get placed on. Let's use yahoo as an example. Yahoo often post articles on their site that have been ripped from pr web or other popular pr sites. Will there be link juice from yahoo as far as google in concerned? Would be interesting to know seen as they block juice from pr sites. But basically, spamming press release sites is just a waste of effort. Or have you found results to contradict this?
