If your business relies on your website for revenue or business, then you need to know what it's doing and how it's working. And that means tracking your site visitors and measuring the effectiveness of the site.

It's possible to measure your site's success using your log files and a spreadsheet, but that's hard. You can use a basic log analysis tool, such as those that come with most Web hosting packages. Or you can get a software solution that integrates with your Web servers. It depends upon what you need and what you're willing to spend.
