Probably the best way to get free inbound Google backlinks is post on forums. I really like sites like: www.sitepoint.com, http://forums.digitalpoint.com, and www.5staraffiliateprograms.com. All you have to do is register, set up your signature with a link to your site/sites, and start posting! Make sure not to shamelessly promote your company, In fact you will be booted off the forum completely if you do that. The best way to go is to start news related topics or post in other people’s topics about something you know something about. Everytime you post a comment you get a free inbound link. Not all posts will get you a link, but the more you post the more links you will acquire. Make sure that all available employees in your company are actively posting on forums and linking to your site or affiliate sign-up page. No go out and start posting!
