Let’s talk about it from the front to the back. You need to first check whether the number of new user registrations and the number of old users logging in has dropped. If there is no problem, check whether the page views of the product details page have dropped. If there is no problem, check whether there is a problem with the number of orders generated. If there is no problem, go to See if there is any problem with the order payment.
There may be problems in the middle. For mobile number list example, if there are fewer new users, it may be that there are fewer users from the channel, or there may be a problem with the user registration page. This needs to be looked at in detail, and the product manager needs to know the reason for the problem. There is a general understanding. For example, if the amount of orders generated is reduced, it means that there may be a problem with the order module.
It is also possible that there is no problem with the business link. At this time, it is necessary to check the problem of the customer unit price. Because the order volume has not decreased, and the transaction volume has decreased, the customer unit price has dropped. This requires you to see if there is a problem with the wrong product price. It is necessary to see which commodity prices have changed, and find anomalies from these commodities.
