UTM Generator Tool: Campaign URLs GA4 Understands

The three rules that prevent 90 percent of UTM problems

• Always lowercase. GA4 is case sensitive: Facebook and facebook are two different sources.
• No spaces, no special characters. Hyphens instead of spaces. Otherwise you end up with encoded strings nobody can read.
• One dictionary for the whole team. Define once how sources and mediums are named (facebook, not fb; paid-social, not cpc-social) and stick to it. The templates suggest exactly these standards.

When you should not set UTMs at all

Never put UTM parameters on internal links within your own website: that overwrites the visitor\u2019s real source and makes reports worthless. And for Google Ads: with auto-tagging (gclid) enabled, manual UTMs are a deliberate addition, not a replacement.

How the parameters travel cleanly through the funnel into your CRM, and what that has to do with attribution, is on our Tracking & Analytics page. For everything else: a free intro call via Contact.
