About of Search engine optimization (SEO)

Search engine optimization (SEO) is the method of increasing the volume and excellence of traffic to a web site from search engines via "natural, organic or algorithmic search results. Naturally, the top a site's "pr" (i.e., the earlier it comes in the search results list), the new visitors it will receive from the search engine. SEO can also aim different kinds of search, including image search, local search, and industry-specific vertical search engines.

As an Internet marketing policy, SEO think how search engines work and what people search for. Optimizing a website mostly 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.

The contraction "SEO" can also pass on to "search engine optimizers," a term adopted by an industry of consultants who carry out optimization projects on behalf of clients, and by employees who perform SEO services in-house. Search engine optimizers may provide SEO as a stand-alone service or as a part of a broader marketing campaign. Because helpful SEO may need changes to the HTML source code of a site, SEO tactics may be incorporated into web site development and design. The term "search engine friendly" may be used to describe web site designs, menus, content management systems and shopping carts that are easy to optimize.

Another class of techniques, known as black hat SEO or Spam indexing use methods such as link farms and keyword stuffing that degrade both the relevance of search results and the user-experience of search engines. Search engines appear for sites that employ these techniques in order to delete them from their indices.
