Search engine optimization (SEO) is the process of improving the volume and quality of traffic to a
web site from
search engines via "natural"
search results. 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 relevancy, 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, and making sure that the content is easily indexed by search engines and also appeals to human visitors. The acronym "SEO" can also refer 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.

The term webcam is also used to describe the low-resolution digital video cameras designed for such purposes, but which can also be used to record in a non-real-time fashion. News
