Google Analytics is a superb, FREE, data-driven tool that can help you with the information you need.
To find which pages on my website receive the most traffic. Check out your Content Optimization > Content Performance > Top Content report. This report counts the visits and pageviews for each page of your site, as well as the average amount of time that visitors spent on each page, how frequently visitors left your site after viewing the page, and the $Index. Pages with the highest $Index are those pages which were commonly visited prior to high-value conversions during the same visit. This report is useful for finding the key content that should be a part of the main flow of the site. You can also compare two date ranges, by clicking on the Date Range Comparison icon on the blue Date Range title bar.
