Does Piano Analytics prioritize the campaign tracking parameters or the referrer for source attribution?

If you're using campaign tracking parameters to track your marketing campaigns, this information will appear as the source for any visits initiated through a tracked link.

Thus, the campaign tracking parameters will always be prioritized over the referrer if it is present in the first hit of a visit.

On the other hand, links that are not tracked using campaign tracking parameters will be assigned an organic source based on the referrer.
