Duplicate Content
Definition: content that is repeated verbatim or closely repeated on another area of the web. Search engines rely on organization and efficiency – to that end, they will not index duplicate content so as to avoid index clutter. When you are creating new content for your website, steer clear of duplicate content in all forms; this means no copied and pasted content in an attempt to make your site appear fuller, and taking the time to make sure that all of your content is unique and relevant.
