What i found was the following:
Title tag: "Google"
Meta keywords: None
Meta description: None
Number of words on www.google.com: 56
Just 3 words are repeated more than once and they are:
- "Google" (and "Google" is also in the title tag)
I wouldn't recommend leaving out keywords or descriptions for any site, however i also wouldn't tell Pele how to play football. Google owns search, they can do what they want, and when it comes to their home page the content is all that matters. I'm sure they might have a couple of links to boost their search rankings too...
