You're an SEO. Should you use Google tools? I think Google spies on people personally what with the tracking cookie etc. What do you think? Is it wise to or of any benefit at all to use Google Analytics, Webmaster tools?
Ummm, why wouldn't you use Google Analytics? First, it's probably the best free web analytics software available. Webmaster tools provides information that any webmaster and SEO consultant would need, considering it's the only valid information your going to get.
