I am selling in-content links in my PR4 article directory site. The site has more than 147,000 articles written by 5,700++ authors. So how does this work? You choose a word or words. For instance, you choose the word "debt consolidation". All the articles containing that word will link to your site using that word as the anchor text. That amounts to massive amount of content links!

Price: $30/keyword per year
PM for site and payment information.
