UTM parameters
UTM parameters are tags added to a link, such as utm_source and utm_campaign, that say where a visit came from.
An example
example.com/quote?utm_source=meta&utm_campaign=solar-tx tells you the visit came from the Texas solar campaign on Meta.
How EventsIQ handles it
UTM values travel with each lead, alongside the click id that reports the sale.
