Search Engine Optimization is the process of enhancing the volume and quality of site visitors to a particular website or a particular web page by search engines like Google, Yahoo, and Bing. SEO targets unpaid web traffic and not direct traffic from advertisers. Therefore SEM has two sides, which can be aptly defined as on one hand search engine optimization which is concerned with making a site user-friendly so that he will submit it to search engines like Google or Yahoo, and on the other hand, off-site optimization which is concerned with generating a high amount of targeted traffic from search engines only.
A well-optimized website is a well-known search engine favorite and can easily come at the top of results in Google and Yahoo if it has carefully chosen its keywords. The search engines do not allow the use of too many keywords in an article, but the relevant keywords should appear many times. The article directories will also decide the ranking of a site by counting the number of times the keywords appear. These keywords must have good keyword density. If these keywords appear very seldom, it will lower the ranking.
Another important aspect of SEO is content writing. This refers to the number of articles, videos, audio, and other content that will be uploaded to a particular site. The more content the better it is for SEO. The keywords should be used wisely throughout the content. If possible it is better to hire an expert who specializes in content writing services to optimize the site
