From Wikipedia, the free encyclopedia
Search engine optimization (SEO) is the process of
improving the volume and quality of traffic to a
web site from
search engines via "natural" ("organic" or "algorithmic")
search results for 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. SEO can be approached in many ways, but the
latest trend is
Performance Based SEO.
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 web site
development and
design. The term "search engine friendly" may be used to describe
web site designs,
menus,
content management systems,
URLs, and
shopping carts that are easy to optimize.
