This week, we rolled out a few new reports for you to become familiar with and love!

1. Clickthrough ratio: in the Clickthrough report, we're now calculating the ratio of Clicks to visitors for each ad.

2. Page view time! In the page view report, you can now see how many seconds, on average, people spent on each page spread.

3. Engagement Factor. We used the formula: (visits/visitors)*duration to compute an Engagement Factor (EF). Engagement is one of those things where no one has really come up with a standard definition yet, but I read about this formula somewhere and it seems useful as a gauge of how valuable people find each page. This is displayed (along with a cool graph) in the page view report.
