Cost per Time buys ad inventory for a fixed period at an agreed price, regardless of clicks or impressions, as used for reserved NAVER and Kakao banners.
CPT purchases time rather than an outcome-based unit such as a click or impression. The effective impression cost therefore depends heavily on traffic during the reserved period. High-traffic slots, including commuting and lunchtime periods, can book out quickly, so reserve dates well in advance for major campaigns.
Reserved delivery makes expenditure predictable and allows concentrated brand exposure during a specific period, such as commuting hours, without auction competition.
Actual impressions or clicks may fall short of expectations without triggering a refund. Use historical traffic data to estimate the likely return before booking.
