PROBLEM TO BE SOLVED: To perform retrieval result ranking with the tastes of users reflected thereon. SOLUTION: A retrieval result ranking method includes: a score calculation step for calculating scores to be used for the ranking in order of displaying in a retrieval result through the use of evaluation values tabulated by user retrieval log information stored in a retrieving device 20; and a retrieval result display step for performing the ranking by using the scores and displaying the retrieval result in order of the ranks. The method further includes: a user-specific revisit number of times tabulation step (step S116) for tabulating the number of times of user-specific revisits being the times of the revisits of the users to the retrieval result, based on the times of appearance of the same user identifiers and tabulation keys, on the basis of the retrieval log information in order to tabulate the evaluation values; and an evaluation value tabulation step (step S118) for tabulating the evaluation values, based on the number of user-specific revisits which is tabulated in the user-specific revisit number tabulation step.
