过去被阿里后台检测为重复产品的，只要改改标题就OK。而“两两匹配计算”新政实行后，图片、标题、属性、关键词、描述中，只要有两项存在“近似”，即会被系统识别为重复产品。重复产品不但客户搜索不到，而且数量达到一定程序，还会影响到全店的搜索权重。

In the past, it was detected as a duplicate product by Alibaba background. Just change the title. After the implementation of the new policy of "pairwise matching calculation", as long as there are two "approximations" in pictures, titles, attributes, keywords and descriptions, they will be recognized as duplicate products by the system. Duplicate products can not only be searched by customers, but also reach a certain number of procedures, which will also affect the search weight of the whole store.
