Amazon claims the changes aim to simplify the commission structure. The previous model offered variable rates based on sales volume. This system has now shifted to flat rates for different product categories. You might notice significant reductions in commissions for popular categories like furniture and groceries. Many affiliates report a drastic decline in their earnings since the change. Amazon's strategy may also reflect its desire to manage costs amid increased competition. You should adapt your marketing strategies to cope with these new commission rates effectively. You can do this by increasing organic traffic to your website to make more sales.
