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 Engine Results Pages (SERPS) or the higher it "ranks", the more searchers will visit that site.
