Page Traffic lets you find out which pages are the most popular on your site. For a specified time range, you will see below the graph a list of your most popular pages or URLs. On the same line of each URL, you can see for that URL the number of Page Views, Unique visitors, Entries, Bounce Rate and Average seconds on that Page. You can click on the graphic icon next to the number for each of these stats to graph that particular stat such as Page Views or Uniques for that URL.
Entries tracks how many visitors entered your site on that page meaning that was the first page they visited.
