The numbers are astounding. In October 2018, Americans downloaded or streamed over 550 million podcasts, accounting for roughly 80% of all podcast listening worldwide. The 2018 Infinite Dial study reports that 44% of Persons 12+ have listened to a podcast, up 40% from just a year ago. As consumer adoption grows, advertiser interest in podcasts has exploded. Total spending for podcast advertising is projected to exceed $400 million for 2018.
Listeners now have hundreds of thousands of podcasts at their fingertips, with hundreds of new ones being created every day. Content ranges from general interest to highly specialized, with a spectrum of content that allows anyone to find a program which appeals to their interests.
Podcast listeners are especially valuable to advertisers for several reasons. First, consumers consciously download podcast content with purpose and intent – they are engaged listeners. Second, podcast hosts mingle content with implied or actual endorsement of the brands that support their program, which heightens awareness of those brands.
Podcasts can be an extremely effective weapon for advertisers, but buying this new medium can be daunting. Here are a few key points to know before jumping into the podcast advertising pool:
Most podcasts are sold on the cost per thousand (CPM) model, based on impressions/unique downloads. CPMs can vary widely, from $20 to more than $100. A download counts as one impression (more on this below).
Podcast ads are usually either sold by podcast publishers such as Wondery and NPR, or aggregators such as Podcast One. In some cases, a podcast may also be sold directly by the host.
58% of ads sold are embedded, also known as “baked-in.” This means the ads are inserted prior to the podcast airing and will appear in every download of the podcast episode, whether it’s accessed today or a year from now. Baked-in ads are often voiced by the podcast hosts, providing the benefit of an implied endorsement. Baked-in ads always run immediately prior to the episode (:15 to :30 pre-roll) or midway through the episode (:30 or :60 midroll).
The alternative to baked-in is to have ads dynamically inserted. 42% of podcast ads run this way. Ads that are dynamically inserted are purchased based on the number of impressions that will be delivered. These impressions can run across multiple episodes of the podcast until all the impressions ordered are delivered. Dynamic insertion ads are usually slotted to run pre- and post-roll (:15 to :30) only.
Podcasts are either played in real time (streamed) or downloaded for future listening. For baked-in ads, delivery is measured by the number of unique downloads. For dynamically inserted ads, it’s the unique downloads for the show episodes containing the ad.
