Abstract: An advertisement is delivered based on a first limiting element, a specified number of selections, and an expected selection rate. Based on an expected number of selections and an actual number of selections of the advertisement before the end of a counting period, the number of selections to be further needed at the end of the counting period is estimated. For each of a plurality of second limiting elements different from the first limiting element, an actual selection rate of the advertisement by a group, among the recipients of the advertisement, limited by the second limiting element is obtained. Based on the actual selection rates, a limiting element to be added to delivery requirements from among the plurality of second limiting elements is determined. Based on the determined limiting element, the corresponding actual selection rate, and the estimated number of selections, additional recipients of the advertisement are determined.
