How to use the output
Move from arithmetic to a better decision.
- 01
Agree the taxonomy
Document allowed source, medium and campaign naming before many people create links.
- 02
Use lowercase labels
Consistent casing avoids splitting reports into values such as Facebook and facebook.
- 03
Describe the campaign
Use content and term fields only when they help distinguish meaningful variants.
- 04
Test the destination
Open the completed URL, confirm the page loads and verify campaign values in the analytics debugging workflow.
Tool questions
Definitions and limits, answered.
01What does utm_source mean?
It identifies the platform, publisher or origin used in your reporting convention, such as google, linkedin or newsletter.
02What does utm_medium mean?
It identifies the broad channel or distribution method, such as cpc, paid_social, email or referral, according to your documented taxonomy.
03Should UTM values contain spaces?
The builder safely encodes spaces, but consistent lowercase labels with hyphens or underscores are easier to govern and compare.
04Does this tool store my URL?
No. The page generates the URL in your browser and does not submit the form values to GrowthLabs.
