Short for
search engine results page, the Web page that a
search engine returns with the results of its search. The major search engines typically display three kinds of listings on their SERPs. Listings that have been indexed by the search engine’s
spider, listings that have been indexed into the search engine’s directory by a human, and listings that are paid to be listed by the search engine.
