You must configure unique tracking settings for your affiliate links in Google Analytics in order to track them. A custom report with dimensions like “Affiliate Link” and “Campaign” and metrics like “Sessions” and “Revenue” is one of these parameters. Another is adding a custom parameter at the end of the URL. In order to optimize your affiliate marketing plan and raise ROI, you can use these parameters to evaluate the success of your affiliate links in Google Analytics and measure the traffic, conversions, and sales they provide.
