When linking to an URL like this www.test .com/test?
mtm_source=meta&mtm_medium=paid-social&mtm_campaign=campaignName&utm_medium=paid&utm_source=ig&utm_campaign=123456&fbclid=PAaWdyZAOdRkdleHRuA2FlbQEwAGFkaWQAAAZPLvpGVHNydGMGYXBwX2lkDzU2NzA2NzM0MzM1MjQyNwABp8Ghj9rcY1PBqpw3Dy0KDTnzHcYN8ZefjGiQYZ6g2OIAUy0SMEBExEDpgMP I am wondering what values the dimensions source, medium and campaign will hold in my campaign reporting.
Will Matomo (on-premises hosting) always prior MTM parameters over UTM parameter or is there any documented logic how this works and does not end up in a complete mix up of campaign information?
When constructing URLs that contain both MTM and UTM parameters for the same property (e.g., mtm_campaign=invest_webinar&utm_campaign=invest_tips), the MTM parameter takes priority. In this example, the campaign value will be invest_webinar.
When constructing URLs that contain both MTM and UTM parameters for different properties (e.g., mtm_campaign=invest_webinar&utm_source=newsletter), the values for each parameter are used.
If you use multiple parameters for the same property (e.g., mtm_campaign=invest_webinar&mtm_campaign=banking_guide), the value is taken from the parameter listed first. In this example, the campaign value will be invest_webinar.
