One of my more recent observations in reviewing web sites in recent years, is the tendency to give web users too many options on a web page. Not only does adding too many links on your site confuse your visitors and reduce conversion rates, it may actually hurt your search engine rank. Having a high link to content ratio, especially for new sites, can present a problem.
From what I've read recently, Google tends to prefer links that slowly progress with content over time. This presents a challenge to new sites that may want to link everything within an article, hoping for the best search engine results. I guess slow and steady wins the SEO race as well.
