Douyin's delivery time does have an impact on the score, but it is not the only determining factor. Douyin's scoring algorithm takes into account multiple factors, such as product quality, service attitude, after-sales service, etc. Although delivery time is one of the important factors, if other aspects are not good, it will be difficult to get a high score even if the delivery time is fast.

Therefore, as a seller, in addition to making the delivery time as fast as possible, you also need to improve your service quality in all aspects to get a higher evaluation score.
