Previously, podcast ad slots were reserved for only one type of advertising message - a sponsor read from the podcast host themselves or pre-recorded ads from different brands. Interchangeable Ad Slots allow Acast to automatically detect if a sponsor read slot has not been sold on a show, and instantly override the setting to deliver an ad in its place instead. This increases the inventory available to advertisers and ensures fewer ad slots go unsold.

Acast has been trialing Interchangeable Ad Slots with a group of creators for some time and will now roll it out across its network. These early tests have seen the feature increase the capacity of Acast’s marketplace by more than 10 percent.

“We’re continually exploring product enhancements to increase the value proposition of our marketplace to advertisers and, in turn, earnings potential for our podcast creators. Interchangeable Ad Slots allow us to pursue our mission of building the most valuable podcasting marketplace in a scalable, automated way” says Ross Adams, CEO of Acast.
