垃圾索引

在数位行销以及网络广告领域中，垃圾索引（Spamdexing，也被称为搜索引擎垃圾、搜索引擎污染、黑帽SEO、搜寻垃圾以及网络垃圾）^[1]是指恶意的操纵搜索引擎索引系统（search engine indexing），有很多种方法可以污染搜索引擎，像是加入大量的垃圾连结或是与内容无关的语句，进而增加与搜寻关键字的关联性以及网站的SEO排名。^[2]^[3]

搜索引擎如今透过各种算法来决定各个网站与关键字的关联性排名，像是判断关键字有没有出现在网站的正文或是网址中。许多搜索引擎还会自动侦测垃圾索引并移除可疑的页面，并且，搜索引擎业者在收到用户抱怨后也可以迅速地封锁一个污染搜索引擎的网站提供的所有搜寻结果。在搜索引擎优化产业中，使用不道德的手段提升网站排名也被称为“黑帽SEO”，这破坏了提升网站排名的规则以及搜索引擎方针，因此，冒险进行搜索引擎污染的网站在Google Panda以及Google Penguin搜寻排名算法中都会受到严厉的惩罚。^[4]^[5]

常见的垃圾索引技术分为两大类：内容泛滥^[6]（或词语泛滥）以及连结泛滥。^[7]
