I see here http://www.alexa.com/siteinfo/google.com in section "How engaged are visitors to google.com?" exsist 3 parameter:
Bounce Rate
Daily Pageviews per Visitor
Daily Time on Site
"Daily Pageviews per Visitor" = how much pages user open e.g. can open 3 page from domain.com or can leave page without open any new page.
"Daily Time on Site" = this mean how much time people spend on website.
My question, "bounce rate" is maked from this 2 parameter and depends of this 2 parameter or bounce rate is separately calculated by some other parameter?
