I'm writing an article about UTM best practices for tracking and governance. I'm especially interested in hearing from people who work at enterprises and have experience managing lots of UTM tracking links. I'm also happy to hear from other businesses too, but enterprises are the focus here. Give me: 1. What you recommend as best practice. 2. What problem it solves. 3. Actionable steps on how to do it. 4. Bonus points for if you can show evidence of it working in your business.
