Bobbing for Ranks

I have come across in the past week a lot of puzzling sites....what I mean by this is site with sufficient amount of keyword enriched content and absolutly no ranks on any search engine.....
The puzzling thing is that the sites are listed in the search on these search engines and I am not sure really why this may be....if anyone reading this blog has suggestions please let me know.....

Some examples would be Client 1918 and Client 2007
These are two sites for example that I have found today and can't totally grasp why, except for just stripping the content and rewriting completely but if there is an easier less time consuming way I am all ears.....

Second on a personal note it is a sad day in the life of Andy Dick........WHAT HAPPENED!!!

OH WAIT I FORGOT YOU HAVE TO HAVE TALENT TO HAVE A CAREER
