Search Engine Optimization (SEO) to improve the visibility of a website or a web page in search engines like Google, Yahoo, Microsoft Bing etc. This is all done as natural results, also known as un-paid or organic search results.
In general, the higher ranked site and pages on the search results page are more frequently visited by potential clients. The more frequently a site appears in the search results list, the more visitors it will receive from the search engine's users. SEO may target different kinds of search, including image search, local search and even video search.
As an Internet marketing strategy, SEO considers how search engines work, what people search for, the actual search terms or keywords typed into search engines and which search engines are preferred by their targeted audience. Optimizing a website involves editing its content and HTML and associated coding to both increase its relevance to specific keywords on search engines. SEO includes backlinks, or inbound links which makes a site more liked and visible for Google.
Search engine optimizers may offer SEO as a stand-alone service or as a part of a broader marketing campaign. Because effective SEO may require changes to the HTML source code of a site and site content, SEO tactics may be incorporated into website development and design. The term "search engine friendly" may be used to describe website designs, menus, content management systems, images, videos, shopping carts, and other elements that have been optimized for the purpose of search engine exposure.
