Posted by MikeCP There's no such thing as a free link. Whether it was the time taken to craft that blog post, the cash used to film that viral video, or even just the opportunity cost of thinking about how to build links, there is an investment involved. For my first post here at SEOmoz, I want to talk about how a small business might approach the investment into link building. To make this post a little less hypothetical, we're going to set a budget of $2,000 and/or 60 hours.
