iHeart AdBuilder uses a state-of-the-art algorithm combined with real world survey-based data to dynamically insert your ad at the most optimal times to play your audio ad on the most optimal stations. This way we maximize the number of impressions you get in your targeted audience within your weekly budget.
The average iHeart AdBuilder campaign gets most impressions from ad plays during the more prime times, such as AM Drive and PM Drive. However, there's a lot of value in non-prime time airplay. 33% of adults 18+ listen to the radio between the hours of midnight and 5am! Even the biggest advertisers access overnight inventory as part of a healthy radio campaign.
