Abstract: A method of and server for ranking documents in response to a query are provided. The method includes determining a target resource hosting a document, and generating a first and a second randomly-selected value for the document. During a first time interval, the method includes acquiring a query and generating a first ranked list of documents to the query based on the first randomly-selected value. The first ranked list includes the document at a promoted-rank position. During the second time interval, the method includes acquiring a query and generating a second ranked list of documents to the query based on the second randomly-selected value. The second ranked list includes the document at a demoted-rank position. The promoted-rank position in the first ranked list is above the demoted-rank position in the second ranked list for increasing a gap in user traffic to the document between the first and second time intervals.

Abstract: There is disclosed a method and system for ranking a web resource. The method comprises: receiving a set of features associated with the web resource; generating a raw quality score based on the set of features, comparing the raw quality score to a reference score, the reference score being associated with a similar level of user traffic as the web resource; applying an offset adjustment formula to the raw quality score in response to an offset between the raw quality score and the reference score to obtain an adjusted quality score; in response to receiving a query, generating a search engine result page (SERP) including an indication of the web resource at a ranked position based on the adjusted quality score, the adjusted quality score causing a future raw quality score to be closer to a future reference score associated with a future level of user traffic.
