Search engine optimization (SEO) means your site is as accessible as possible to the search engines to improve the chances when potential customers type specific search terms. It is the process of improving the volume and quality of traffic to a web site from search engines via “natural” or “algorithmic” search results for targeted keywords.

Usually, a site is presented in the search results according to its “ranks”. SEARCH ENGINE OPTIMIZATION 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.

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 SEARCH ENGINE OPTIMIZATION 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 indexes.
