Why You Should Track Your KPIs
KPIs are the most important parameters in decision-making in affiliate marketing. KPIs help marketers assess campaigns’ results and affiliates’ performance. This is useful as it enables you to know the performance of the affiliates and the strategies that they are using.
Using this information, you can make rational decisions, including freezing the budget for low-producing affiliates, changing the content placement, or modifying the commission structure to meet the desired outcome. It’s not just numbers – it is the information that can shape the future of your affiliate program.
The Importance of KPIs in the Development of Affiliate Programs
An affiliate program must have measurable results to grow in the long run. Program growth metrics include active affiliate count, retention rates, and earnings per click (EPC) to establish whether the program is growing and running effectively.
Thus, by monitoring the program growth metrics, businesses can determine which performers to keep, which new partners to seek out based on their performance and incentives, and which weak points to eliminate.
Furthermore, KPIs highlight how to invest in technology, partnerships, and marketing to grow the program and make it profitable. Simply put, it is possible to scale an affiliate program without KPIs, but it is like driving without a map – one will most likely waste time, money, and other resources.
The Consequences Of Neglecting KPI Tracking
This is especially true in the current affiliate marketing world, characterized by competition due to neglecting KPIs. Missing important metrics can prevent a business from spending more money on low-productive campaigns or taking advantage of highly converting affiliates.
This can lead to poor budget control, hence reduced returns on investment, and also hurt affiliate retention, as partners may wish to exit due to poor guidance or subpar compensation.
Also, when operating in an environment where competitors already use analytical tools to optimize their strategies, falling behind with KPIs means you will be left behind. Therefore, it is not enough just to use KPIs; it is crucial to survive, grow in the market, and retain profitability.
