I decided to start using and supporting Piwik. I would like to give some comments for possible improvements:
Visitor Loyalty - How many visits? 1, 2, 3, …, >100
Visitor Recency - Days since last visit? 1, 2, 3, 4, …, >100
Visitor Age - Days Since First Visit? 1, 2, 3, 4, …, >100
Extended Liveview - full page with all users online during the last x Minutes. If you click on a user, the clickstream should be visible and information about user history.
I suggest to implement the plugin “sitesearch”. It would be important for many users, to have information about the use of internal and external (google) search terms. This could be used, to learn more about the visitors interests.
Do you think, these features could be useful?
