What is SERP?

SERP stands for search engine results page, and is the listing of web pages returned by a search engine in response to a keyword query. These results normally include a list of web pages with their titles, a link to the page, and a short description showing some of the keywords that have been matched with the 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.
