Pre-Roll
Pre-Roll audio ads stream directly before the publisher’s content begins. Since Pre-Roll ads precede featured content, they are generally viewed as more informative than intrusive. They can help improve brand awareness, engagement, favorability, and purchase intent.
Available in both streaming and download environments.
Mid-Roll
Mid-Roll audio ads are similar to traditional commercial breaks and play in the middle of the publisher’s audio content. Listeners who reach a Mid-Roll ad are usually highly engaged and more likely to continue listening to the featured content until the end. As a result, this placement often achieves high completion rates.
Available in both streaming and download environments.
Post-Roll
Post-Roll audio ads play right after the main content ends. Because they come after the featured content, they are effective for prompting listeners to take immediate action.
Available in download environments.
