What is Search engine optimization? 
Search engine optimization (SEO) improves a website's placement on search engines. Using methods that search engines employ to rank a page, a search engine optimization company can make your website appear on the very first or second page of a search engine's listings for relevant keywords.
The theory is that the earlier (or 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.
