Amazon account health rating scores are updated every 7 days. System issues For Amazon rankings, they are based on system algorithms. Of course, we don't know Amazon's ranking mechanism, because it is updated from time to time, so the ranking of products will also be affected. However, several key factors such as Amazon product reviews, sales, BSR rankings, product conversion rates, etc. are key factors that affect Amazon's natural rankings. For example, the importance of reviews is now getting higher and higher, so everyone should also guide buyers to leave good reviews.

Of course, sometimes the Amazon system will have bugs, which will cause the natural rankings of all products to disappear. In this case, you don't have to worry too much, just pay attention to the system message and wait for recovery.
