You can access guide analytics by clicking on the options icon on the top left corner of the guide, and then selecting Analytics:
The first part of the analytics shows the total aggregate views of your guide by day. By default, it shows the last month, but you can change the time span using the buttons above the graph.
The second part of the analytics shows guide engagement by page. Each bar represents the pages in your guide. The higher the bar, the more popular that page is compared to other pages. The darker the color, the higher the user engagement (factors including time on page, comments, repeat visits).
Finally, on the bottom it shows the top referring websites that users are coming from, the newest subscribers, and the most recent comments within the guide.
