A Search Engine results page, or SERP, is the listing of web pages returned by a Search Engine in response to a keyword query. The results normally include a list of web pages with titles, a link to the page, and a short description showing where the keywords have matched content within the page. Some of the major search engines also provide a link to their own cached version of the page, which they store locally on their own servers for reference. A SERP may refer to a single page of links returned, or to the set of all links returned for a search query.

SERPs of major search engines like Google and Yahoo! may include different types of listings: contextual, algorithmic or organic search listings, as well as sponsored listings, images, maps, definitions, or suggested search refinements. The major search engines also offer different types of search, such as image search, news search, and blog search. The SERPs for these specialized searches offer specific types of results.

SERPs usually contain advertisements. This is how commercial search engines fund their operations. Common examples of these advertisements are displayed on the right hand side of the page (e.g. Google Adwords) as small classified style ads or directly above the main organic search results aligned with the organic results to the left, usually boxed on a pale colour to subtly distinguish the difference between paid and organic listings.
