SEO – Case Study: adobe.com
The first result for searching the term "click here" on Google is adobe.com. This seems strange when looking at the adobe web site. There is no mention of that term when looking through the adobe site (title, meta tags, description, etc.). So, on page optimizations is not having any affect, the fact that a huge amount of highly ranked trusted pages link to adobe for products (specifically adobe reader) is putting it at the top of the results.
Many of the sites linking to Adobe are using the terms "click" and "here" to send visitors to access Adobe content. A large majority of these sites have a high page rank.
So, the main point is that on page omptimization is important, but off page optimization is far more important.
