There are many ways to track visitors to your blog. You could use a service like Nedstat which offers free page count analysis. If you look towards the bottom of the menu, you will notice a small and unobtrusive icon of a graph. If you click on that you will go to the site analysis page for Weblog Tools Collection. There are various other free counter services out there. Some of these are very intrusive and insist that they place a huge banner on your site along with the number, others prevent unauthorized access to the information. An interesting statistics site for bloggers is BlogPatrol.com They are tuned for bloggers and their statistics are very attuned to user tracking and click through evaluations.
There are some other interesting ways to track visitors. On my main blog, in which I use b2 as the CMS, I use a tool called b2stats This can be implimented through this b2hack from The Protagonists’ Blog I use it all the time and it gives me a fair idea of what is going on with the insides of my blog.
