  • <p>One recent speculation I have heard (<em>have not tested yet</em>) that I believe may have some merit is the idea that Google is now attributing more value to links that <strong>send traffic</strong>, so instead of a link is a link is a link, and beyond link juice being a derivative of DA/PR, links that are <em>used</em> may now be worth more.</p>
