Piwik provides a powerful and easy to use functionality that is designed to help you measure how many times a piece of Content was seen by your users, and how many times it was clicked on. We call this feature Content Tracking. Content Tracking reports how often a specific ad or a banner was displayed on any of your pages and how often a visitor actually interacted with them. We call these two parts content impression and content interaction. This feature is not only limited to ads or banners. You can use it for any kind of content. Learn more about Content Tracking.
