There is amazing Company Aweber. The #1 Rated Auto responder and Website Tracker!!!
You don’t have to pay for stat programs.
All of the below are free and I recommend testing them all out until you decide you are happy with one:
Google Analytics: Google Analytics is the stat program of choice at the moment, and there’s just too much to this to even begin to review it. The main feature of Analytics is that for new users it is very, very simple to use, however it is also a powerful tool and offers some incredible features for advanced users.
Woopra: Woopra offers live web tracking and real time analytics which are the main features of it. You’re able to get a good and general idea of what your visitors are doing. It’s also a very advanced statistic program and is right up there with Analytics in terms of options and tracking.
I would also like to mention clicky. clicky is really sick, and you can use it for free (although there are payment plans you can use to get a lot more out of it).
With clicky you basically can sit there and watch actual real time view of your visitor. You see how they came in to your website (from what page or search engine phrase), and you can sit and watch them as they read through your website, browsing from page to page all the behavior of your website visitor.
It’s absolutely vital that you keep up to date on your website stats. You don’t want to know just how many hits you are getting per day, you want to know what your visitors are doing, where they are coming from and what keywords they are using so that you can optimize your website for them.
