Please speak with the Support team for help with setting up tracking for Google Analytics.
We are able to add Google Analytics (and any other analytics platform) tracking to all links going through the affiliate programme. To do this please speak with the support team for setup.
With Google Analytics, we recommend the following utm setup:
utm_source=publisher id.publisher name
utm_medium=affiliate
This will allow better reporting within GA - please note this article around GA4 and validating transactions based on channels (ie - don't - but with reasons why).
