Search engine optimization (SEO) is a subset of search engine marketing, and deals with improving the number and/or quality of visitors to a web site from "natural" (aka "organic" or "algorithmic" search engine) listings.
In effect, SEO is marketing by appealing to machine algorithms to increase search engine relevance and ultimately web traffic.
SEO strategies vary widely, in accordance with the specific site.
Broadly speaking, SEO may be geared towards increasing either, or both, the total number and quality of visitors from Search Engines.
