I notice when I do a google search for some keywords I get back some website hits that do not match my search criteria but instead redirect me to their search page with my google search terms pre-populated.

For example If I search for anything to do with Salesforce I get back this site http://blog.jeffdouglas.com EVERYTIME.

For instance if I search "visualforce component blog"

In google results the 4th or 5th result is http://blog.jeffdouglas.com/?s=visualforce+component+blog Even thought that page does not contain my search phrase but instead brings up a list of items that it thinks will match by terms.

How do I do this?
