Back in 2009 (was it really that long ago?!) Rand wrote a post titled Perfecting Keyword Targeting and On-Page Optimization, which is one of the most popular blog posts on SEOmoz. It is still referenced as much today as it was back in 2009. The core principles haven't changed that much, but there are some new additions to an SEO's toolkit when it comes to on-page optimization. Today I want to focus on what these new additions are in relation to eCommerce websites.
