SEO (Search Engine Optimization) is the process of affecting the online visibility of a website or a web page in a web search engine's unpaid results--often referred to as "natural," "organic," or "earned" results. SEO may target different kinds of search, including image search, local search, video search, academic search, news search and industry-specific vertical search engines. SEO differs from local search engine optimization in that the latter is focused on optimizing a business' online presence so that its web pages will be displayed by search engines when a user enters a local search for its products or services.
