Search engine optimization or SEO is a process to improve the volume and quality of traffic to a particular web site from search engines via organic search results. Generally, if the site appears higher in the list of search results, it receives more visitors from the search engine. In order to make sure that more and more people visit a particular web site, SEOs target different kinds of search engines like local search, image search and industry-specific vertical search engines.
SEO considers how a search engine works and what people normally search for in order to make the most out of their internet marketing strategy. Optimizing a web site primarily requires editing of its contents and HTML and associated coding that would increase the relevance to specific keywords and remove barriers to the indexing activities of search engines.
