But to know whether your programme is actually working, you need to track the right **KPIs (Key Performance Indicators)**. At AmpTeck, we see too many businesses drowning in vanity metrics that don’t move the needle. The trick is to focus on KPIs that show **real growth, efficiency, and profitability**. Here are the 12 most valuable KPIs to track — and 3 “metrics” you can safely ignore. ## **Benchmarking KPIs** 1. **Sales per Affiliate** Shows how much revenue each affiliate generates. Helps you spot top performers, set incentives, and identify where to focus support. 2. **Year-over-Year Growth** Tracks long-term improvement of your affiliate programme and highlights trends in sales and partner performance. 3. **% of Affiliate Sales vs Total Sales** Reveals the contribution of affiliates to your overall revenue and whether your programme is pulling its weight. ## **Affiliate Performance KPIs** 1. **Conversion Rate** How many clicks turn into actual sales. High rates prove your affiliates are reaching the right audience. 2. **Revenue per Click (RPC)** Shows how much money you earn on average from each click. Great for testing campaign quality. 3. **Clicks** A basic indicator of interest. Useful if paired with conversion data, but don’t stop here. 4. **Customer Lifetime Value (CLV)** Measures the long-term value of customers acquired through affiliates. A powerful metric for understanding sustainability. ## **Programme-Level KPIs** 1. **Revenue** The big picture number. Track affiliate-driven sales to evaluate your programme’s true impact. 2. **Reversed Sales Rate** The percentage of sales cancelled or refunded. Helps assess product quality and affiliate credibility. 3. **Fraudulent Orders** Protects your bottom line. High chargeback rates or suspicious activity should raise red flags. 4. **% of Active Affiliates** Not all affiliates will be consistently active. Tracking this percentage ensures you know who’s driving value. 5. **Cost per Sale / Lead (CPA/CPL)** Shows what it costs to generate a sale through affiliates. Vital for comparing with other channels like paid ads. ## **Metrics to Ignore (Vanity Traps)** 🚫 **Impressions** — Looks nice, tells you nothing about sales. 🚫 **Initial ROI** — Early returns can be misleading. Affiliate growth takes time. 🚫 **Traffic Engagement Metrics** — Page views and bounce rates don’t prove revenue impact. ## **Final Word** The right KPIs give you clarity: where to double down, which affiliates deserve more support, and how profitable your programme really is. At **AmpTeck**, we help SMEs cut through the noise by combining **enterprise-grade tracking dashboards with local expertise** — ensuring you only focus on the numbers that matter. 👉 Ready to build a performance programme driven by data?
