Yes, Amazon store performance has a direct impact on sales.

Store performance is reflected in many aspects, including order defect rate, cancellation rate, late delivery rate, email response time, and policy violations. These performance factors will affect the seller's ranking and exposure on the Amazon platform, thereby affecting sales. If the seller's performance is poor, it may lead to a drop in product ranking, reduced exposure, and even a ban on selling on Amazon.

Therefore, Amazon sellers need to pay close attention to their store performance indicators and take appropriate measures to improve and enhance them to increase sales.
