Hi there, WordPress.com doesn’t currently support Google Analytics tracking, but we do offer built-in statistics showing you most of the same types of information as Google Analytics would display.
You can view your site’s stats by clicking the stats link in the grey admin bar at the top of your site. Find out more about how stats are measured and reported.
You can also install Google Webmaster Tools, which contains some of the same functions as Google Analytics. Learn how to activate it.
Just let me know if you need further help.
