Pulse Pro 1.7.2 introduces a new feature, visitor stats. This feature is not intended as a replacement for a full blown analytics package such as Google Analytics, but it gives a quick overview of your website's traffic. There are only three metrics used, daily visitors, top referrers and top pages. This basic set of information will tell you how many people are coming to your site, where they are coming from and what content they are viewing.
To track visitors on your site, just add the tracker embed code to the footer of any page you'd like to track. If your site uses a master template, you can just include it in the footer and it will track all pages that use the template.
