You can create a UTM link while adding or editing a link in Linklibs.
Here is the screenshot of the app when you are adding or editing a link.
As you can see the UTM Link Builder is part of the Link Entry window.
You can add utm parameters by clicking on the “+” button.
The drop down box beside the utm parameters allows you choose parameters used in previous links.
As you change the parameters it generates the UTM Link automatically.
To copy the link simply click on the copy button on the right. It copies the link to the clipboard.
All the UTM Parameters and the UTM Link is saved to the database while saving the link.
Linklibs doesn’t makes it mandatory. But it is suggested by Google Analytics that when you use UTM parameters, it is always better to specify the source, medium and campaign.
