What exactly is SEO?

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

Typically, the higher a site appears in the search results, 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 search engines. This gives a web site web presence.
