Definition of Search engine optimization:
Search engine optimization can be defined as the process of increasing the amount of visitors to a Web site by ranking highly in the
search engine results of any search engine. The higher a Web site ranks in the results of a search, the greater the chance that that site will be visited by a user. It is common practice for Internet users to not click through pages and pages of search results, so where a site ranks in a search is essential for directing more traffic toward the site.
