Search engine optimization is the process of affecting the online visibility of a website or a web page in a web search engine's unpaid results—often referred to as "natural", "organic", or "earned" results.
SEO is of two types:
On Page SEO and Off Page SEO
On Page SEO - On-page SEO is the practice of optimizing individual web pages in order to rank higher and earn more relevant traffic in search engines.
Off Page SEO - Off page SEO refers to techniques your can use to improve the position of a web site in the search engine results page (SERPs). Many people associate off-page SEO with link building but it is not only that.
