Analytics of google

I have just recently added the standard google analytics to 2 sites as a test, before finding PIWIK. has only some 50 pages, but all are required to cover the history of the subject.

Now currently the analytics I have has been less than what I would like. So I am looking to use PIWIK across all pages as it seems this is so much more customizable, however, exactly how to do this I am not sure and would appreciate support.

I need to have stats from all pages across my site, and then with new pages to be added I am needing stats across articles and sections of those pages to show entry / exit point and navigation across certain pages only, but not all pages. How can I achieve that please??

Many thanks all
