UTM parameters
Use UTM parameters to attribute campaigns.
Last updated June 3, 2026
UTM parameters tell Grometrics which campaign, source, medium, and content brought a visitor or app session in.
Event model
| Event | Used for |
|---|---|
| utm_source | Source and campaign reporting |
| utm_medium | Channel grouping |
| utm_campaign | Campaigns page |
| utm_content | Creative or link variant context |
What happens next
Open a tagged URL, then check Traffic Sources and Campaigns for the captured UTM values.
Troubleshooting
Data is missing
Confirm the tracker is installed, the site ID is correct, and the event is not blocked by consent or an ad blocker.
Data looks duplicated
Confirm the tracker is initialized once per page or app boot.
