Hi, I have been experimenting with press release websites, some are free, many are not. However I have found that writing a press release can be more effective for an instant surge of traffic and can pick up extra back links too. I only use: http://www.release-news.com its free to register and once a press release has been approved it goes straight into Google News. As Google News drags results into organic search (often very high) for sometimes a few days, If you get the right story together you can get thousands of hits to one story and the results are instant. You have also got a good chance of being picked up by other sites which use Google News. Just make sure you write a decent release and the results can be great. At http://www.release-news.com its currently free to register and submit, links can also be included
