所謂站群，一般是指同一個用戶組建多個的網站，為了提升每個網站對搜索引擎的權重，單獨為一個或幾個網站配置一個獨立的IP，這樣做是網站SEO優化的重要一部分，如果這些網站結構或內容好又大致相同，那么更需要獨立IP去支撐，否則這類網站域名都解析到同一個IP，搜索引擎會輕易認定是垃圾網站，網站權重自然不會提升。The so-called site group generally refers to the establishment of multiple websites by the same user. In order to enhance the weight of each website to the search engine, an independent IP is configured for one or several websites separately. This is an important part of SEO optimization of websites. If the structure or content of these websites is good and roughly the same, then independent IP is more needed to support them. Otherwise, the domain names of these websites are resolved to the same An IP, search engine can easily identify is rubbish website, website weight won't rise naturally.
