Other words SEO is the process of optimizing the amount of visitors to a website by ranking it high in the search results of a search engine. The higher the ranking a website, the greater the chances of a website to be visited by users. Thus SEO helps you get the traffic from search engines by ranking you higher than millions of other websites of the same field. It is a common practice of the Internet users to explore through the top most pages of a search query rather than going through pages and pages of long results. So holding top rank will direct the traffic to your website.
