SEO is process of increasing the amount of visitors to a web site by ranking high in the search results of a search engine. The higher a web site ranks in the results of a search, the greater the chance that site will be visited by a user.It is aimed at improving the ranking of a website in search engine listings, and could be considered a subset of search engine marketing. The term SEO also refers to "search engine optimizers," an industry of consultants who carry out optimization projects on behalf of clients' sites.
