Google Analytic Google Site Map

Dear Friends,
The Google Analytic provide so many facility, like total visitor, unique visitor, page views, pageviews time, boncing rate (most important), try to decrease the bouncing rate its increase in so some condition...
1. if the our open page is our exit page.
2. if the visitor is close the page without explore our inner web pages.
if the page view time increase so the bouncing rate is decrease....
(google analytic also provide the goal...its basically reffer to inter-linked pages. e.g shopping site..1 is preduct page..2 is price / basket page...3 is payment conformation or thanku page).
its also show the visitor location, the visitor is come...directrly, through refreal or through search engine..or its come from which keyword.

sometimes we c the if www.sumitkumar.com or sumitkumar.com have different pagerank but though the google site map we solve this problem we choose the option www.sumitkumar.com or sumitkumar. com is same, its also called a cronical domain.
