SERP: stands for “Search Engine Results Page” – and is the listing of results returned by a search engine in response to a keyword query. The results normally include a list of items with titles, a reference to the full version, and a short description showing where the keywords have matched content within the page. A SERP may refer to a single page of links returned, or to the set of all links returned for a search query. For further reading; a useful page can be found at WikiPedia
