1. A correction device comprising:
a memory; and
a processor coupled to the memory, the processor being programmed to:
acquire: (i) an arrangement position of distribution information within a predetermined webpage layout when the distribution information arranged in the predetermined webpage layout is displayed on a display screen of a terminal, and (ii) a click rate of the distribution information at the arrangement position;
generate a first database storing the acquired arrangement position of the distribution information and the acquired click rate of the distribution information, the first database correlating the arrangement position and the click rate of the distribution information at the arrangement position;
acquire: (i) a specific position in the predetermined webpage layout displayed on the display screen, and (ii) an attention degree index, which is a click rate of a pixel coordinate position in the predetermined webpage layout, indicating a degree of attention of the specific position as compared to another position in the predetermined webpage layout;
generate a second database storing the acquired specific position in the predetermined webpage layout and the acquired attention degree index, the second database correlates the attention degree index with the specific position in the predetermined webpage layout;
when the arrangement position of the distribution information corresponds to the specific position in the predetermined webpage layout, extract the attention degree index from the second database correlating to the specific position;
when the extracted attention degree index is not equal to the attention degree index at the other position in the predetermined webpage layout, correct the click rate of the distribution information at the arrangement position stored in the first database, the corrected click rate being: (i) increased when the extracted attention degree index of the specific position corresponding to the arrangement position of the distribution information is less than the attention degree index at the other position, and (ii) decreased when the extracted attention degree index of the specific position corresponding to the arrangement position of the distribution information is greater than the attention degree index at the other position, such that the corrected click rate of the distribution information at the arrangement position is equivalent to the click rate at the other position in the predetermined webpage layout; and
update the first database and distribute the distribution information based on the corrected click rate to the terminal to be displayed on the display screen of the terminal at the arrangement position.
