Question 1

Is my text sent to a server?

Accepted Answer

No. Everything runs in your browser with JavaScript. Nothing you type is uploaded, and closing the tab clears it.

Question 2

Which fields are required?

Accepted Answer

Source, medium and campaign name are the three Google Analytics expects. Term and content are optional.

Question 3

Are UTM values case-sensitive?

Accepted Answer

Yes. 'Email' and 'email' appear as different rows in reports, so stay consistent and use lowercase.

Question 4

Should I use UTMs on internal links?

Accepted Answer

No. They can overwrite the real traffic source of a visit.
