Other than Google Analytics, any other software or free system that I can use? Please comments. Thanks
You can download the request log produced by the Web server and make your own analytics using the program FWTLogstat2. FWTLogstat2 is a free program that helps you in analyzing the log file produced by the Apache Web server. It gives you a report of the pages that were visited, the last access date, the amount of bytes transferred, and the number of requests. This report can be sorted by name of the page, bytes transferred, or number of requests. Filters can be applied to the report regarding the date and day of the week of the visit, and the name of the page. For example, you can see how many visits had the pages whose names begin with "page", on the weekends of the month of July.
