1. Category hidden
Many children's shoes often ask their opponents why they can't see the category rankings?
We usually rely on the ranking of competitors to judge the sales volume of our competitors and the sales trend of our competitors. Then some competitors asin have no ranking at all, and even if we write a rank map of our competitors and walk on the keepa map, we cannot see it. ? What is the reason? First of all, it is mentioned here: it is because of a bug in the Amazon system , and this situation generally occurs in some categories that lose their rankings and are most likely to be concentrated. The main reason is that the Amazon system does not include information on this asin category, or The system loses category information, which often exists in the Amazon system. Using the Amazon bug , it is not difficult for us to find out how to hide the category. Today Xiaoxiao will take you to see why:
Similar to this: asin – B096FPMP6M
We can't see his rank 
2. Reason
And for some products, we can't see his major categories, such as keyboard categories
The reasons such as keyboard categories are caused by system category classification, while other cases are caused by artificially changing categories. The current method is:
Since the system records the existing bugs in the category nodes , if a number of node SKU categories are merged into variants, different category nodes may be lost. By modifying the nodes in the background to make the nodes of each variant inconsistent, the category ranking can be achieved. It is possible to be hidden, and there is also the hidden effect that can be done by refreshing and updating the table without filling in the node.
Will it affect the traffic after the category node is hidden? The current statement is not clear. According to the observation of the front desk, it seems that there is no impact on the sales of listings . The keyword ranking window of products without ranking is still higher than the products with ranking or even more comments. Of course, some people say that no ranking will affect the sales of some products.
