Hey there!
Since you got into affiliate marketing (good choice, I wish you good luck on your journey!), you’ll have more and more links to track and analyze, so I think you could use an affiliate dashboard. That way you can keep track of the conversions, and have an overview of affiliate link performance. For example, a click page performance report shows commission, conversions, and conversion rate. Take some more time to look into this, you can export it to Google sheets if it’s easier for you to find your way around this way.
Affiliate marketing can be a great source of income when you do it properly, so get familiar with the best practices or you can learn how to track affiliate links with Google Analytics, that’s another great option.
