Search engine optimization (SEO) is the process of improving the volume or quality of traffic to a web site or a web page from search engines via "natural" or un-paid search results as opposed to search engine marketing (SEM) which deals with paid inclusion.

The theory is that the higher a site appears in the search results list, the more visitors it will receive from the search engine.

SEO may target different kinds of search, including image search, local search, video search and industry-specific vertical search engines.
This gives a web site web presence.
