Google eyes 'cloaking' as next antispam target

Google's Matt Cutts, in charge of much of the search giant's antispam efforts, tweeted over the past week that Google plans to take a closer look at the practice of "cloaking," or presenting one look to a Googlebot crawling one's site while presenting another look to users.

Still, it's rare for Cutts and Google to announce this type of algorithmic shift so publicly, which implies they're giving Webmasters a warning shot in order to reexamine their sites before the ranking changes go into effect, and that rankings may be a little fluid as it rolls out.
