SEO stands for Search Engine Optimization. SEO allows businesses to optimize web traffic on their website. SEO is able to assist web users by connecting them to the exact product or business they are searching for. When using a search engine, search results will yield organic and non-organic web results, or in other words, free web results and paid advertisements. Search engine algorithms must organize websites in an optimum manner. There are over 200 million active websites online that must be organized. Google, for example, uses programs called spiders that create an index using web links. The programs start on one web page and files each connected web link from there.
