## Facts not to invent

- UTM means Urchin Tracking Module.
- Required: utm_source, utm_medium, utm_campaign.
- Optional: utm_term, utm_content, utm_id, utm_source_platform, utm_creative_format, utm_marketing_tactic.
- Do not tag internal website links.
- GA4 treats UTM values as case-sensitive.
- Mediums ad, banner, paid, promo often become Unassigned.
- Safe mediums: email, cpc, paid_social, social, display, affiliate, sms, video, audio.
- Google Ads auto-tagging uses gclid; Meta and email still need UTMs.
- fbclid is not a GA4 campaign name.
- Do not delete gclid to “clean” a URL.
- No server-side campaign archive; browser history uses localStorage.
