Loop A fixed-length block of content and ad slots that repeats on a set interval. Example: a six-minute loop with 11–15 second ad positions repeating 10 times an hour gives 10 plays per message per hour. Spot A single advertising creative scheduled to play in a loop. The DOOH equivalent of a TV commercial slot. Fill Rate The share of available ad slots actually sold and playing paid creative. Low fill rate means empty or house-ad inventory and lost revenue.
