A search engine results Page (SERP) 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.
Search Result Methods
Major search engines like Google, Yahoo! and Bing primarily use content contained within the page and fallback to metadata tags of a web page to generate the content that makes up a search snippet. The html title tag will be used as the title of the snippet while the most relevant or useful contents of the web page (description tag or page copy) will be used for the description. If the web page is not available, information about the page from dmoz may be used instead.
