There is no clear quantitative limit on the qualified click-through rate of Doudian. Because the click-through rate will be affected by many factors, such as product quality, operation strategy, promotion methods, etc. Therefore, although a certain click-through rate can help increase store exposure and sales, the specific qualified standard needs to be judged according to the specific circumstances of different industries, products, competitors, etc. In addition, the click-through rate is not the only criterion for measuring the quality of Doudian operations. It is also necessary to comprehensively consider the store's conversion rate, customer retention rate and other indicators.
