Visitor Time On Site
Piwik shows you how long a particular visitor remained on your site. This stat and bounce rate is very good indication of good quality site. For example if your site has long written content and bounce rate for the page is above 90% then you can conclude that people are ignoring it. On the other hand short posted text also has high bounce rate and that doesn’t give you any idea about quality and visitor retention. You have to use other factors like shared items on social network and backlinks to determine the quality and user feedback.
Piwik lets you view the traffic sent via search engines. Other than the hit count from each search engines you also get - bounce rate, actions and time spent by that user on your site. This is important information as you can see this will help you build much better website.
