Google have launched a new program called co-op which incorporates human feedback into its search results. Although the system is still very new and not very useful at the moment, it is something you should start looking into if you aim to gain good results on Google.

Google co-op works by allowing human editors to assign a label to a url which allows users to find very specific and targeted results. The system also allows users to subscribe to certain content. This shows Google that the content from a particular site is trusted, so it is more likely for that site to perform well in search results.

This is a very interesting topic and for more information you can visit http://www.profitchoice.com/articles/coop.php
