Hey! I have some good news on this. Currently, and since version 1.0, AnalyticsWP does in fact respect and save UTM_* params in the database. Eventually, we will add reporting, features, etc around this data.

Point is, people who are using AnalyticsWP now with UTM_* params will have all that data available retroactively down the road :)

Yeah Getting UTM tags tracked is super important for an analytics solution. Any site running ads is going to need a way to identify their ads traffic and conversion data. Not sure how useful this solution can be without this support.
