I am having an issue with tracking Google Shopping as the GCLID is dropped from the URL. The issue seems to be that I am not able to add any parameters to the URL and the issue is only occurring on product pages.
For example, the issue occures on this page when adding the parameter "gclid=TeSter-123".
Why is the parameter dropped when loading the URL?
Visually these are always dropped.
However if you can not track data, this is most likely due to you choosing manual UTM tracking in Google Analytics. Make sure to have it set to automatic.
If you are adding manually GCLICK I'd then in analytics you need to turn on manual tracking of Glick
If you are not setting any Glick I'd manually then In analytics keep Glick yes tracking on as automatically.
Also in Google ads in settings check tracking options.
