UTM Naming Conventions
| Rule | Example |
|---|---|
| Always use lowercase | facebook not Facebook |
| Use underscores for spaces | spring_sale not spring-sale |
| Be consistent across teams | Create a shared UTM dictionary |
| Include dates for campaigns | black_friday_2025 |
| Avoid special characters | Use URL encoding if needed |
Case Sensitivity Matters!
Wrong:Facebook, FACEBOOK, FaceBook
Right:facebook
GA4 treats these as 3 different sources - always use lowercase
