Question 1

What does UTM stand for?

Accepted Answer

UTM means Urchin Tracking Module. These parameters identify where traffic came from and how each campaign performs.

Are UTM parameters case-sensitive in GA4?

Normally no. UTMs are for tracking, but can create duplicate URL variants. Canonical tags should handle this on your site.

Should I use UTMs for organic social posts?

Yes, if you want campaign-level clarity. Use medium=social and consistent source values per platform.

Can I use UTMs for email campaigns?

Accepted Answer

Yes. Use source=email or newsletter and medium=email, then separate email placements with utm_content.

Question 6

What is the difference between source and medium?

Accepted Answer

Source is where traffic came from. Medium is the type of channel. Example: source=google, medium=cpc.

How many UTM parameters should I use?

Should I use UTMs on internal links?
