AliExpress' 48-hour online rate usually starts during the mid-year big promotion period, such as Double 11, Black Friday, etc. This is an event launched by AliExpress to attract more consumers and increase sales. During these two days, sellers can enjoy the preferential policies given by the platform, including reducing platform fees and providing marketing resources. In addition, AliExpress will increase official promotions to help sellers gain more exposure and increase the sales rate of their products. Therefore, AliExpress's 48-hour online rate can greatly increase sellers' sales revenue and promote consumers' willingness to buy.
