Of course Jim.
Doing SEO for a website and ranking in google will bring in general quality traffic and will boost your rank in Alexa.
but if you rank higher in Alexa will this help with google? From my experience no. Maybe you have other opinion, Jim?
You rank won't even shake. I believe that Alexa rank is a useless service and their ranking process is horrible. Anybody can get a good rank buy driving traffic to their site. You just need to install Alexa toolbar and there you go.
