Article spinning is a search engine optimization technique by which blog or website owners post a unique version of relevant content on their sites. It works by rewriting existing articles, or parts of articles, and replacing elements to provide a slightly different perspective on the topic. Many article marketers believe that article spinning helps avoid the feared penalties in the Search Engine Results pages (SERP) for using duplicate content. However, if the original articles are plagiarized from other websites or if the original article was used without the copyright owner’s permission, such copyright infringements can result in the writer facing serious legal consequences.
Website owners may pay writers to perform spinning manually, rewriting all or parts of articles. Writers also spin their own articles, manually or automatically, allowing them to sell the same articles with slight variations to a number of clients or to use the article for multiple purposes, for example as content and also for article marketing. There are a number of software applications which will automatically replace words or phrases in articles. Automatic rewriting can change the meaning of a sentence through the use of words with similar but subtly different meaning to the original. For example, the word “picture” could be replaced by the word “image” or “photo”. Thousands of word-for-word [more information at Wikipedia]
