Upon request, you can use our registration sources tracking functionality, which is used for things like following conversions through UTM, among other things. 

To do so, you need to add the wanted URL settings to your links. 

For example: www.my-event.com/?utm_source=linkedin&utm_medium=cpc (you can generate your link by using tools like: https://ga-dev-tools.appspot.com/campaign-url-builder/)

The information passed in the URL will automatically be tracked by Digitevent and associated with the participant who is registering.

Then, from your back office > Contacts, you'll have access to the registration origin.

Note that you can also filter your contacts according to this registration origin.

To do so, use the field : "Registration url query" in your segment condition.
