Three UTMs are required, two are optional
utm_source, utm_medium, and utm_campaign are required for clean reporting. utm_term (paid search keyword) and utm_content (creative variant) are optional. Inconsistent capitalization is the single most common UTM mistake — \”Email\” and \”email\” register as different sources in most analytics platforms.
Frequently Asked Questions
Should UTMs be lowercase?
Yes. Use a lowercase, hyphenated convention (e.g., utm_campaign=fall-sale-2026).
