Thanks for reaching out here @fnoam Here’s more information about channels in our help center - link. Please keep us posted if you need any additional support. 

Hi @fnoam ,

In order to test that your UTM parameters are set up correctly, make sure you are accessing your website via a link that contains UTM parameters. We track the 5 standard UTM parameters;
https://www.docs.developers.amplitude.com/data/sdks/javascript/#enable-via-sdk

If there are no UTM parameters to grab from the URL or nothing in the browser cookie (e.g. the user is in private browsing mode), then there will be no UTM parameters attached because we will disregard null values and act as if the properties don't exist. I'd suggest testing this yourself by accessing your website via a URL with UTM parameters attached. So, if a user doesn't have any UTM parameters stored in their cookie or there are no UTM parameters to parse from the URL, then nothing will show up in Amplitude.

Click on this link for an example URL with UTM parameters set:
https://www.docs.developers.amplitude.com/data/sdks/javascript/#track-utm-parameters

To analyze this in Amplitude, use a "group by" in a Funnels chart or Event Segmentation chart. Here's an example of "referral_source" in Event Segmentation:

Hope this helps, and please let me know if you have other questions.

Im using UTMs on every link i use.
But for some reason Amplitude only shows me some of the sources for example :/

for example, I can see traffic from utm_source=facebook
but i can’t see traffic from utm_source=criteo

Any idea why?

Hi @fnoam , this is certainly odd. I will ask @Jeremie Gluckman the community manager to turn this into a ticket and one of the team will look into this shortly. Thank you!

Thanks @Denis Holmes. I just submitted that for you!

Hi @Denis Holmes @Jeremie Gluckman , any update on this?

Hi @fnoam ,

We do have a ticket for this but are currently dealing with high ticket volumes. However, I have spoken about this with Jeremie and I aim to have someone take the ticket today. Thank you!

Kind Regards,
Denis

Thank you @Denis Holmes!
