Search Engine Optimization
Search engine optimization (SEO) is the process of improving the amount and quality of traffic to a website from search engines like Google, Yahoo and other Internet website via search results from targeted keywords. Usually, the earlier a site is presented in the search results or the higher it “ranks”, the more searchers will visit that site. SEO can also target different kinds of search, including image search, local search, and industry-specific vertical search engines. As a marketing strategy for increasing a site’s relevance, SEO considers how search algorithms work and what people search for. SEO efforts may involve a site’s coding, presentation, and structure, as well as fixing problems that could prevent search engine indexing programs from fully spidering a site. Another class of techniques, known as black hat SEO or spamdexing, use methods such as link farms and keyword stuffing that tend to harm search engine user experience. Search engines look for sites that employ these techniques and may remove them from their indices. The initialism “SEO” can also refer to “search engine optimizers”, terms 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 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, SEO tactics may be incorporated into website development and design. The term “search engine friendly” may be used to describe website designs, menus, URLs, and shopping carts that are easy to optimize.
