Search engine optimization (SEO) is the process of improving the volume and quality of traffic to a web site from search engines via \u201cnatural\u201d (\u201corganic\u201d or \u201calgorithmic\u201d) search results. Usually, the earlier a site is presented in the search results, or the higher it \u201cranks\u201d, 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.<\/p>\n
As a marketing strategy for increasing a site\u2019s relevance, SEO considers how search algorithms work and what people search for. SEO efforts may involve a site\u2019s coding, presentation, and structure, as well as fixing problems that could prevent search engine indexing programs from fully spidering a site. Other, more noticeable efforts may include adding unique content to a site, ensuring that content is easily indexed by search engine robots, and making the site more appealing to users.<\/p>\n
word to the wise: beware of SEO firms using techniques, known as \u201cBlack Hat\u201d 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 their listings (see below)<\/em>.<\/p>\n Because effective SEO may require changes to the HTML source code of a site, SEO tactics may be incorporated into web site development and design. The term \u201csearch engine friendly\u201d may be used to describe web site designs, menus, content management systems and shopping carts that are easy to optimize.<\/p>\n As a marketing strategy<\/strong><\/p>\n Eye tracking studies have shown that searchers scan a search results page from top to bottom and left to right, looking for a relevant result. Placement at or near the top of the rankings therefore increases the number of searchers who will visit a site. A successful Internet marketing campaign may drive organic search results to pages, but it also may involve the use of paid advertising on search engines and other pages, building high quality web pages to engage and persuade, addressing technical issues that may keep search engines from crawling and indexing those sites, setting up analytics programs to enable site owners to measure their successes, and improving a site\u2019s conversion rate.<\/p>\n
