What are UTM codes?
A UTM code is a simple code snippet that you can add to the end of a URL to track the performance of campaigns and content. There are 5 parameters you can monitor: source, medium, campaign, term and content. The metrics you track via UTM codes are shown in analytics reports to give you a clearer view of marketing performance.
Because they are important
Without UTM campaign data, it's easy to attribute ROI to the wrong channel or campaign. You may have data that may seem correct, but are actually misleading. Incorrect marketing data leads to incorrect marketing decisions.
