UTM hygiene: campaign naming conventions that survive reality
Short answer: UTMs only help if everyone spells campaigns the same way—pick a short standard, block manual random tags, and audit monthly for duplicates.
Otherwise reports become “facebook”, “Facebook”, and “fb-promo” forever.
A pragmatic convention
- utm_source: platform (google, meta, newsletter)
- utm_medium: cpc, email, social, referral
- utm_campaign: yyyy-mm_offer-geo (2026-04_winter-hamilton)
Guardrails
Lowercase everything, ban spaces (use hyphens), and document special cases for QR codes or partner links.
Internal traffic
Exclude office IPs where possible; tag internal tests with a dedicated medium so you can filter.
