Can I set up only utm_source?
I remember that I read somewhere says that when setting up utm tracking, utm_source, utm_campaign, utm_name are all required field.
But if I only want to track source ( for example if I want to track traffics from GMB) can I just put ?utm_source=GMB?
Would it still work?
update: I just found where did I saw it, it`s actually Google`s offical guide, it say :
When you add parameters to a URL, you should always use utm_source, utm_medium, and utm_campaign.
utm_term and utm_content are optional.
utm_ is simply the required prefix for these parameters.
I wonder why it said that~
