Search engine optimisation (SEO)Search engine optimisation (SEO) is the process of improving the volume or quality of traffic to a web site from search engines via "natural" or un-paid ("organic" or "algorithmic") search results as opposed to search engine marketing (SEM) which deals with paid inclusion.
SEO may target different kinds of search, including image search, local search, video search and industry-specific vertical search engines.
As an Internet marketing strategy, SEO considers how search engines work and what people search for.
The acronym "SEO" can also refer to "search engine optimisers," 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.
Search engine optimisers may offer SEO as a stand-alone service or as a part of a broader marketing campaign.
