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. 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 may result in the writer facing a legal challenge, while writers producing multiple versions of their own original writing need not worry about such things.
Article spinning is best way to use same article in different forms. Its about changing the sentences and words manually or by using software.
