Search engine optimization (SEO) is the process of improving the visibility of a website or a web page in search engines via the “natural” or un-paid (“organic” or “algorithmic”) search results.
This process, using a variety of techniques, is to increase the ranking of a website and achieve top placement for its chosen key phrases or key words on the organic search results or search engine result pages (SERP’s). Simply said, it is to bring new customers to your web site through worldwide search engines and popular search phrases that are related to your site topic.
