Does it worth $340 to post your pres release on the http://www.prnewswire.com/news-releases/ ?If not, can you post some cheaper alternative sites
http://www.prlog.org/ is free, I wouldn't pay for publishing of press releases, for writing them yes, but not for publishing them ;-) SY
I would also not pay for PR submission but in some cases when I would see tons of visitors coming to my website, then I won't mind paying $50-100 for that; may be $340 too. There are few PR sites (paid) that directly shows your PR in Google news and you can get 2000+ visitors instantly within hours. So paying or not paying, it all depends on what we are focusing at. Hope this helps.
24-7pressrelease.com, prlog.org and free-press-release.com are all good and offer free links. You can pay free-press-release.com around $30 for a customised release with anchor text which will get good distribution if the news is "newsworthy"
What about SEO-wise? Posting a link on http://www.prnewswire.com/news-releases/ would increase my ranking or wouldn't make such an impact and wouldn't be any difference if I submit it to free directory like http://www.prlog.org/ PR6 ?
Don't waste much money like that for a PR submit when you can't sure about the benefits it can bring back to you.
