Refined operation of Amazon

Precise operation of Amazon:
The most important thing is to add a certain tracking code to the last payment page to record the user's uin on this page,
Finally, in comparison with the successful payment uin, the default part of the middle is the user with a tendency to pay, to give specific care to this part of the user, the effect will be very obvious.

Contrast:
1. the user who jumps to CFT for payment is recorded at the Point store.
2. Record the users who have successfully paid for the purchase;
3. The comparison between the two shows the problem that we need help in this step. This is the requirement.

Like other scenarios, we should record and collect user behaviors. Do we know how users use our products and what difficulties they encounter?
What measures can we take to help customers? This is the requirement. It is so simple that there is nothing advanced, and it can only be done step by step with the intention of doing it.
