As we all know, press releases are a pretty old strategy to get backlinks. But I haven't really seen any case studies or people talking about them much (services such as prweb.com or some of the services that are available on BHW). Does anyone have experience with them? I am considering a press release on prweb, it costs $100 for a basic one but I'm just curious about whether these have any value at all. I believe most links will be nofollowed, but I would still like to diversify my link profile thanks to some halfwit who decided to overoptimize my best keywords. Not penalized for them, but Google does do some pretty retarded shit and I want to be on the safe side.
