Don’t want all the extra stuff the Google Analytics stats offer, instead prefer something really simple? Then try WordPress’s stats plugin.
Download the plugin from here. See some screen shots here: http://wordpress.org/extend/plugins/stats/screenshots/
It is another simple and user-friendly plugin, with basic statistics. If you are looking for more complex, in-depth stats, then, as mentioned earlier Google Analytics Stats is your best option, but if you are a person after simple metrics, then you are on the right path. You can keep track of the number f pages viewed, what the most noted posts are, where your traffic comes from and what they leave for you when they go out.
