Event based metrics are insufficient. Clicks measure engagement with links, not with content.
Content consumption
Measuring between clicks
{window_top: 100, window_height: 700, doc_height: 3400, time_on_page: 90, ... }
Counting engaged time
{window_top: 100, window_height: 700, doc_height: 3400, time_on_page: 90, engaged_time: 62, ... }
Data architecture
In-memory DB (realtime traffic)
MongoDB (page-by-page historical)
