Rotation
The algorithmic distribution of a scheduled ad across various days and hours within the flight period to ensure diverse audience reach.
What is Rotation?
Rotation is the scheduling algorithm that prevents an advertiser's spots from airing at the same time every day. If 25 spots over a five-week flight all aired at 7:14 AM Monday, they would hit one commuter segment repeatedly and miss every other listener. A proper rotation spreads those 25 spots across multiple dayparts and weekdays so total Reach is maximized.
Modern broadcast traffic systems automate rotation using algorithms that also respect advertiser-specified constraints: stay out of the daypart where a competing product airs, avoid back-to-back placements, cluster around specific program adjacencies. Good rotation is invisible when it works and painfully obvious when it doesn't.
Why it matters
Proper rotation prevents ad fatigue by ensuring the exact same listeners do not hear the ad at the exact same time every single day.
Monitor rotation quality on every buy
Spotwise verifies rotation distribution for every monitored campaign so advertisers can confirm they're getting the reach they paid for.
