We target is to view conversion reports based on traffic source, but google analytics show me only macro sources of traffic - like Facebook, Youtube, direct and so on. But i need more details. I give different links to different facebook communities, for example: https://imbahase.com/?c=facebook_community1 or https://imbahase.com/?c=facebook_community2
If user registers on my site i save his refferal code(facebook_community1, facebook_community2 and so on) to my database.
The problem i met is that i need to view conversion reports filtered by referral code, to decide which publics converts better then another. How should i pass this data to google, and how to build reports i descrived higher?
I am currently using google tag manager and google analytics
UPDATE. SOLUTION I WAS LOOKING FOR:
Actually my tracking code is nearly same as campaigns in google analytics, so all i need is to get query string and do smth like
ga('set', 'campaignName', trackingCode); ga('set', 'campaignSource', trackingCode); ga('set', 'campaignMedium', trackingCode);
