The core key technology of Amazon evaluation lies in the careful cultivation of buyer accounts. The reason why it is called the core key is that the first condition for evaluation and ordering is to have an active buyer account. Buyer accounts are not used once, so the process of maintaining accounts is crucial. However, in the process of maintaining accounts, many people often overlook an important detail-the success rate and weight of the first order. The first order is not only a preliminary test of the account's activity, but also directly related to the subsequent improvement of the account's weight and overall performance. Therefore, when we maintain an account, we must attach great importance to the success rate of the first order to ensure that each evaluation can lay a solid foundation for the healthy development of the account.

Many sellers and service providers often encounter various problems when operating their first order. This article does not intend to delve into technical details, but focuses on the importance of equipment selection and configuration, and their respective roles.
At present, a relatively complete and efficient way is to use a mobile phone and a PC together. These two devices play different roles and functions in Amazon reviews.
Mobile phones play a key role in Amazon reviews, especially in the first review phase. According to Amazon's regulations, users are only eligible to leave reviews after spending at least $50. Therefore, newly registered accounts cannot directly leave reviews on the same day. In order to cope with this limitation, the current practice is to place an order of at least $50 immediately after registering a new account on the same day, and use a credit card to pay for the first order, so as to directly enable the review function. The success rate and weight of the first order are crucial. Once the first order is successful, subsequent operations will hardly encounter the risk of order cancellation or account closure. This conclusion is based on actual testing of a large number of accounts.

In terms of device selection, Apple phones are the first choice, and jailbroken older models such as Apple 6s-7 should be used. The newer the model, the better. Versions 12-12.4 are recommended because they are more stable. Newer models such as i8-11 are not suitable for this purpose. After completing the basic configuration of the phone, you still need to debug parameters, install specific software, and configure foreign servers and independent dedicated IP to create a complete and independent mobile phone operating environment.
However, relying solely on mobile phones is not enough. In order to ensure the security and weight of the account, subsequent operations should be transferred to the computer to improve the convenience and efficiency of the operation. However, the computer also needs to deal with the anti-association problem to avoid the detection of software and hardware device parameters and cause the account to be blocked.
During the entire self-supporting process, it is crucial to ensure that each account has an independent and secure network environment, that is, to prevent association. In addition, it is necessary to select a suitable network environment according to different sites. The environment plan needs to be continuously updated with Amazon's risk control strategy, so either the ability to solve risk control or an early warning mechanism to deal with risk control must be available.
In addition to the security of the underlying environment, the evaluation also requires a complete set of processes and systems such as the account maintenance cycle, the number of orders, safe account maintenance methods, store review control, and advertising strategies. When conducting the evaluation, certain techniques should be followed, such as testing by the conversion rate of visits, and strictly complying with the evaluation safety threshold to ensure the safety and effectiveness of the operation.
