Duplicate content is content that is found on a website that is similar, or may even be identical, as that of another site on the Internet. If the content of an article or blog is an exact match, then it is considered to be duplicate content. Oftentimes, duplicate content is unintentional, but sometimes it is done on purpose so as to manipulate search engine rankings, and redirect traffic to a specific site. It can be noted that the same article written in a different language is, however, not considered duplicate content.
