Google: Underscores are now word separators

According to Matt Cutts who spoke Saturday at WordCamp 2007, Google is treating (or will treat very soon) the underscore used in URLs as word separator. This is a great news and a new challenge for SEO professionals. Blog softwares such us TypePad or Movable Type are also affected because, by default, the underscores are used instead of hyphens.

Other presentation highlights:

• Google treats URLs with a query string the same as static URLs.
• The number of slashes in URL does not affect Google rankings.
• The file extension from URL won't affect the rankings

And a final tip: if you want to have your blog included in Google News, the first condition is to be a multiple user blog ;)
