In a search for the term “reading level”, with the Reading Level set to Advanced, I still had a basic About.com page in the first page of results, as well as this blatant SEO spam page as result No.8.

Although not that much different from the standard search, except that using Advanced Reading Level blocked a result from the scumbag SEO spam domain directhit.com on the second page of plain results.
