1/ Marketwire - This is a fairly expensive service, but covers even more than prweb and has so far, provided fantastic SEO benefits. After emailing the press releases, targeted key terms and more to the company, I receive a phone call to double check everything is okay and the staff are very friendly and they seem a very good company. 2/ OfficialWire- I've ordered a months of unlimitted press releases for a very decent price. I didn't had too much faith, but when an article has been published, it's entered on the front page of google for that term under the news section every time. So it certainly does a good job - Highly recommended for businesses that don't have the biggest budget for press release distribution. Marketing Geek
