Short for search engine optimization, the process of increasing the number of visitors to a Web site through high rankings in the search results of a search engine. There is a greater chance that users will visit the site the higher they sit in the search results. Internet users rarely click past the first few pages of search results, so high rank in SERPs is a great way of lifting traffic to a site. SEO also ensures that a site is accessible to search engines and improves the chances that the site will be indexed and favorably ranked by the search engine.
