A store can sell many products. Taobao has no restrictions. However, it will affect the long-term operation of your store and its survival rules. Generally, it will affect the following: 1. Product traffic is scattered and there is no accurate customer traffic;

2. Product keywords are not concentrated, which makes it difficult to optimize;

3. When uploading products in multiple categories, Taobao only defaults to one category ranking. If you want to change the product category in the future, want to rank quickly, or do an event, it is not easy to get a fast rise in ranking.
