What are the best free affiliate marketing tools?

For Cake PMS (Affiliate Marketing Software) reporting and analytics, you get real-time tracking and performance dashboards that show clicks, conversions, revenue, and partner metrics, with customizable reports by affiliate, offer, or channel, plus exports and alerts to help optimize campaigns and spot issues like fraud or traffic caps. You can also drill into campaign and e-commerce performance down to SKU level if you’re tracking sales from affiliates, though very advanced visualization may need exporting to BI tools.
