utm_source— origin (google, facebook, newsletter)utm_medium— channel (cpc, social, email)utm_campaign— campaign name (black-friday-2026)utm_content— variation (banner-a, banner-b)utm_term— keyword (paid search)
UTM best practices
- • Always lowercase: instagram, not Instagram
- • Use underscore or hyphen: black_friday or black-friday
- • No spaces, no accents, no special characters
- • Keep it consistent — variations create duplicate sources in Analytics
- • To create new tracked URLs, use the UTM Builder
