Short answer
UTM parameters are tags appended to a URL to identify the source, medium and campaign that sent traffic, along with optional term and content values. Analytics tools read these tags to attribute visits and conversions to specific campaigns. Consistent naming conventions are essential, since inconsistent tags fragment reporting.
