Libsyn Unveils September 2023 Podcast Advertising Rates

Liberated Syndication Inc. (“Libsyn”), the leading all-in-one podcasting platform for creators and advertisers, announced its September 2023 Podcast Advertising Rates, including the highest and most accessible CPM categories, and touched on advancements in its brand safety and sustainability targeting solutions.

The Podcasting Advanced: Building Brand Trust & Safety

Podcast advertising elevates consumers’ brand awareness, sparking curiosity, driving engagement, and boosting their interest in making a purchase from that brand’s products of services, according to Nielsen’s ‘Podcasting Today’ report. This is driving home why brands are increasingly choosing podcasts as a medium for advertising, but they want to ensure brand safety and protection of their reputation across such digital audio campaigns.

That’s why Libsyn is committed to prioritizing brand safety for its advertisers. The Company’s AdvertiseCast marketplace leverages ComScore technology to scan and analyze the transcripts of individual podcast shows within the marketplace, enabling contextual profiling of their audio inventory. These integrated components work seamlessly together to score shows, empowering brands to ensure ad placement safety and suitability.

Dave Hanley, Chief Revenue Officer of Libsyn’s AdvertiseCast, affirms, “Our advanced brand safety and suitability solutions prioritize advertisers’ peace of mind. Through our AdvertiseCast marketplace, we utilize ComScore technology to meticulously analyze podcast show transcripts, enabling contextual profiling and show scoring. This commitment ensures brands can confidently navigate the digital audio landscape.”

The following rates, which are denoted as cost per thousand or CPM, are published monthly by Libsyn’s AdvertiseCast, the industry’s premier podcast advertising marketplace that connects advertisers with podcaster. The Company releases the figures to empower the podcaster and advertiser communities to readily monitor market pricing and provide greater insight into podcasting advertising as a monetization vehicle. The data is derived from actual sales data across AdvertiseCast’s network of thousands of shows.

For September 2023, the average CPM rate was $22.91 for a 60-second ad spot. That figure is up 3.8% compared to last month (August 2023 avg. CPM rate: $22.07) and has decreased year-over-year (September 2022 avg. CPM rate: $23.94).

The three highest CPM categories in September based on delivered advertising were:

Education: $27

Moreover, three categories where advertisers can effectively tap into highly engaged audiences at more accessible CPM rates include Fiction, News, and TV & Film, which averaged around the low 20s in September.
