EO stands for “search engine optimization.” It is the process of getting traffic from the “free,” “organic,” “editorial” or “natural” listings on search engines. All major search engines such as Google, Yahoo and Bing have such results, where web pages and other content such as videos or local listings are shown and ranked based on what the search engine considers most relevant to users.
In search engine optimization, on-page optimization refers to factors that have an effect on your Web site or Web page listing in natural search results. These factors are controlled by you or by coding on your page. Examples of on-page optimization include actual HTML code, meta tags, keyword placement and keyword density.
Off page SEO refers to techniques that can be used 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. In general, off Page SEO has to do with promotion methods – beyond website design –for the purpose of ranking a website higher in the search results.
