所谓站群,一般是指同一个用户组建多个的网站,为了提升每个网站对搜索引擎的权重,单独为一个或几个网站配置一个独立的IP,这样做是网站SEO优化的重要一部分,如果这些网站结构或内容好又大致相同,那么更需要独立IP去支撑,否则这类网站域名都解析到同一个IP,搜索引擎会轻易认定是垃圾网站,网站权重自然不会提升。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.
