    The report is based on data from two years ago. Both Google and Yahoo! have implemented a lot of algorithmic changes since then (and Google has redesigned its search engine twice in that time frame). Ask is also about to unleash a new algorithm (if it hasn’t turned on Edison yet).

    This report is neither very relevant nor very interesting for those reasons. It would help tremendously if they do the study again based on 2007 search results (and publish the report in 2007, not 2009).

    If you read the study, you will see that data for the study was compiled in April 2007. Please see the second paragraph of the paper.
