Duplicate Content

 

Content which is duplicate or near duplicate in nature. Search engines do not want to index multiple versions of similar content.

For example, printer friendly pages may be search engine unfriendly duplicates. Also, many automated content generation techniques rely on recycling content, so some search engines are somewhat strict in filtering out content they deem to be similar or nearly duplicate in nature.
