How to use URL params

When you want to know where visitors are coming from you can add certain parameters to your URL. Indiemetrics supports ?ref=, ?source= and ?utm_source=. These can't be used together.

If none of these parameters are set, Indiemetrics will try to use the referrer value set by the browser (only for the JavaScript based version).

In case that the DoNotTrack header is set by the browser, Indiemetrics will drop the referrer entirely.
