Search Engine Optimization - 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. 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. 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 their listings.
