Affiliate programs are built around the idea that businesses reward promoters with a percentage of each sale, known as a commission rate. Some companies keep their rates the same for long periods because they want to build trust and consistency with affiliates. Others adjust rates when competition increases, when products are updated, or when profit margins change. For example, a software company may reduce commissions if marketing costs rise, while an online store may increase rates during holidays to attract more sales. This makes it important for affiliates to keep track of program updates and read terms carefully. Are commission changes something affiliates should accept as normal, or should they focus only on programs that maintain stable rates?
