The best way to know whether your website is achieving its goals is to measure sales. Along the way you should gather extensive traffic data -- not just how many hits you're getting, but which pages are popular, who's visiting your site, when do they visit, and a host of other data that can give you a clearer idea of what's going on. In this way you can test performance at every stage up to the visitor entering your sales pipeline.
In order to get the most from your site, you need to continualy change the contents to reflect what your visitors need. To make the right changes you need accurate, timely, quality information on the numbers of vistors to your site. Where did they come from?, which terms did they search on?, which pages did they visit? what links did they click?
The tools you would use to track all of this information easily are known as Web analytics.
