BAT has its own applet, but at present, WeChat applet has the greatest development prospect. Let's analyze the three. First, the Alipay applet has been online so far, and there has been no movement. I feel that the Alipay applet was once hot, giving people the feeling that I can't live without it anyway. Moreover, for merchants, Alipay applet has little effect, because there are online shopping platforms such as Taobao and Tmall behind it, Alipay. In addition, there are Baidu applets. Since its launch in July, people have placed high hopes on it, especially for small and medium-sized enterprises. But now Baidu's attitude has not been clearly implemented, so the action of Baidu smart applet is not very big now. Finally, the WeChat applet. Why is it the most promising? First, traffic, WeChat is mainly social, with 65.438 billion monthly active users, and no platform can shake it. Secondly, the WeChat applet is in a closed ecosystem, social-applet e-commerce-WeChat payment, plus sharing, which gives the WeChat applet great potential. There is also the rise of new retail, which will also affect WeChat.
