Optimization of website ranking in search engines and directories like google, yahoo, msn

Search engine optimization (SEO) is the process of improving the volume or quality of traffic to a web site from search engines via "natural" ("organic" or "algorithmic") search results. Typically, the earlier a site appears in the search results list, the more visitors it will receive from the search engine. SEO may target different kinds of search, including image search, local search, and industry-specific vertical search engines. This gives a web site web presence.

As an Internet marketing strategy, SEO considers how search engines work and what people search for. Optimizing a website primarily involves editing its content and HTML coding to both increase its relevance to specific keywords and to remove barriers to the indexing activities of search engines.

Search engine optimisation is a way to make websites appear in the search engine's results pages (SERPS). Many people use search engine optimisation companies to do the work for them because it takes too much time to do themselves.

A more common word used to describe search engine optimisation is internet marketing or search engine marketing.

Search engine companies are careful to watch that spam does not affect their search engine results pages by adding filters.
