If you are running a blog, the likelihood is that you’re running it on WordPress.
WordPress has a free plugin called Jetpack that comes with a statistics tracker that sits right in your WordPress dashboard.
Jetpack lets you know how many visits your site gets, and what posts and pages are most popular.
It makes the most popular metrics easy to understand through a clear and attractive interface.
StatCounter is another free website analytics program.
It’s much simpler than the two mentioned above, but it is very easy to sign up for and use.
StatCounter currently offers the following stats: Popular Pages, Entry Pages, Exit Pages, Recent Keyword Activity, Search Engine Wars, Visit Length, Returning Visits, Country/State/City Stats, Recent Visitor Google Map, and more.
