Podcast advertising platforms connect podcasters with advertisers, facilitating the process of buying and selling ads on podcast shows. These platforms help advertisers find podcasts that reach their target audience while enabling podcast creators to monetize their content by selling advertising spots. They can offer various types of ads, such as pre-roll (before the show starts), mid-roll (during the show), and post-roll (after the show ends), as well as different pricing models, like cost per mile (CPM or cost per thousand listens), and direct sponsorships.
