Hi guys, I've recently used this idea with a moderate success. If you have a site with reviews of services, products or whatever you could try it. The idea is the following: most of the companies offering the products or services you review will have profiles on Twitter or other social networks. When you write a (preferably positive) review of their product you can tweet them with info about your review and a link to it. Some of them will retweet your message while others will post a link to your review on their forum or site. Of course, not everyone will do it but some of them will. You should be careful to direct them to a good article in order to increase your chances of success. And also don't overuse the method so it does not look like spam.
