Article spinning is a search engine optimization (SEO) technique by which search engine optimizers post a unique version of relevant content on article directories, web 2.0 sites, or other sources for backlinks.
It is occasionally used by website authors on their own sites but usually avoided because the quality of spun content will be lower than hand written content. Spinning works by rewriting existing articles, or parts of articles, and replacing specific words, phrases, sentences, or even entire paragraphs with any number of alternate versions to provide a slightly different variation with each spin.
This process can be completely automated or rewritten manually. Many article marketers believe that article spinning helps avoid the feared penalties in the Search Engine Results Pages (SERP) for using duplicate content. The extent to which Google and other search engines can detect or devalue spun content is not clear.
However, most uses of spun content are considered a black hat SEO spam practice. This is because most spun content is produced through automated methods and is considered human unreadable. Such content is only usable for mass posting on non-editorial sites purely for SEO; by definition, spam.
The purpose of article spinning is to generate filler content for a site, similar to Scraper sites, which directly rip segments of content away from various sites to make up itself. Sites that have spun content on them most likely have no other content to offer aside from advertisements. Improvements to Google’s search algorithms as of March 2013 have rendered article spinning obsolete.
Article spinning requires “spintax.” Spintax (or spin syntax) is the list of text, sentences, or synonyms that are embedded into an article. To create an article out of spintax, spinning software substitutes the desired synonym choices into the selected article in order to create a new, unique variation of the base article. However, because each article is created from the same set of spintax, uniqueness is lost when the number of spins increases.
