Google关于重复内容的定义
在Google的官方博客上发表了Adam Lasnik的一个帖子，对重复内容作了明确的定义，对于了解关心SEO的应该大有帮助，国内有些朋友可能上Google的官方博客有困难，这里我将其中的定义贴上：
What is duplicate content?
Duplicate content generally refers to substantive blocks of content within or across domains that either completely match other content or are appreciably similar. Most of the time when we see this, it’s unintentional or at least not malicious in origin: forums that generate both regular and stripped-down mobile-targeted pages, store items shown (and — worse yet — linked) via multiple distinct URLs, and so on. In some cases, content is duplicated across domains in an attempt to manipulate search engine rankings or garner more traffic via popular or long-tail queries.
What isn’t duplicate content?
Though we do offer a handy translation utility, our algorithms won’t view the same article written in English and Spanish as duplicate content. Similarly, you shouldn’t worry about occasional snippets (quotes and otherwise) being flagged as duplicate content.
帖子中还详细解释了Google如何处理重复内容的机制，以及Webmaster如何应对重复内容的办法，值得站长们认真地研究。
