Validate every UTM parameter in your campaign URLs against GA4 best practices. This checker detects missing required parameters (utm_source, utm_medium, utm_campaign), mixed casing, spaces, special characters, duplicate keys, and non-standard medium values. Each URL gets a severity rating and an automatic fix suggestion you can copy directly.
Build campaign URLs with correct UTM parameters, then validate them below before launch.
