Slick, but too slick:
Cutts explained that when Google’s crawlers visited a BMW page, it saw blocks of text with repeated key search words such as ‘neuwagen,’ which means ‘new car’ in German. However, when a user visited the listed page they would be automatically redirected to another page with less text and more pictures, which was more attractive than the page the crawler saw, but would have scored lower in Google’s PageRank system.
I’ve always thought about doing something like that, but I’ve never tried it, (1) because I had no reason to, and (2) it sort of breaks the Google ethic of “don’t be evil.”
Interesting though.
