Everything you need to know about UTM parameters
UTM (Urchin Tracking Module) parameters are tags added to URLs that help you track the effectiveness of your marketing campaigns in analytics platforms like Google Analytics 4 (GA4). When someone clicks a link with UTM parameters, those parameters are sent to your analytics platform, allowing you to identify exactly where your traffic is coming from.
In GA4, UTM parameters are essential for proper attribution and understanding your marketing performance. They help you:
Always use UTM parameters consistently across all your marketing channels to get accurate, comparable data in GA4. Even small inconsistencies (like mixing uppercase and lowercase) can fragment your data.
