Your Amazon Store Performance is determined by three different metrics. The first one, customer service percentage reflects how well you're able to satisfy your customers and earn their loyalty over time while also ensuring that any problems are resolved before they become issues--this will help maintain good word-of mouth advertising at maximum levels! Second there's product policy which includes things like return policies for flawed goods or careful packaging when shipping internationally so shoppers know what kind of experience awaited them before opening up the box...and lastly we have shipping that includes maintaining an efficient supply chain from warehouse distribution centers all throughout until delivery.
