    The IAB Australia Podcast has been updated with four sessions from the Audio Summit, including a session about advertising within true crime podcasts, and "the balance of keeping crime content responsible while scratching the itch of crime obsessed Australians".

    “We are losing our network to ad tech.” Writing on X, Lisa Laporte explains why podcasting is struggling. One reason, she says: advertisers are requiring an ever-wider set of technologies in podcast feeds, leading to unreliability and privacy issues.

    Oxford Road's Media Roundtable looks at Spotify's hosting dominance, the IAB Australia's Crime Pays report, and media buyer and planner Spencer Semonson's new phone. Guests include our Editor, James Cridland.
March 5, 2024:
    True crime shows aren’t getting their fair share of podcast ad revenue, in spite of being one of the most popular genres, and skewing younger and more female. IAB Australia has released an excellent report looking at the genre, how it performs for advertising, how to write the best creative for it, and why brand-safety tools might be letting this genre down.

    On Monday, we covered the premium Elfsight podcast player widget, which preloads audio against IAB podcast measurement guidelines. Elfsight mailed us after publication, saying that they had no plans to remove the preload feature. We told them why it matters for podcasters: and they have now confirmed that they will, after all, stop the widget from preloading audio. A new release is due today.
January 22, 2024:
    Caution: The Elfsight Podcast Player widget, a paid-for podcast player, is downloading audio on page-load: against IAB guidelines, and defrauding advertisers. We contacted the company last week to report the issue and invited them to comment. We’d suggest you use Spotify or Apple’s players.
January 18, 2024:
    The Media Roundtable returns this week, with our Editor among the guests. Does podcasting need the IAB? Why isn't programmatic advertising as good as host reads? And are podcasts on YouTube a real thing now?
January 8, 2024:
    Ten podcast companies are still not certified for the latest version of the IAB’s podcast measurement guidelines v2.1, in spite of being asked to do so by the end of 2022. More than a year later, the IAB’s list of compliant companies still shows AdsWizz, Anchor (now Spotify), Buzzsprout, Captivate, Chartable, Libsyn, Megaphone, Podbean, Podtrac and Simplecast as only compliant to v2.0 of the guidelines, something that means “they will lose current status”, according to the IAB Tech Lab.

    Embedded players from ListenNotes, like this, were preloading audio until yesterday, against IAB guidelines. That meant that when your browser loaded a page containing an embedded player, it downloaded the audio in full: which appeared as a valid download in podcast analytics - even if you never listened. After Podnews reported it, ListenNotes has quickly fixed the issue.
December 5, 2023:
    What’s the future for IAB Podcast Measurement? In November 2022, we reported that the IAB’s v2.0 certification would no longer be valid after Dec 31 2023. As of today, some of podcasting’s largest names are still only compliant to v2.0, and all will lose their claim to certification by the end of the year unless recertified: Adswizz, Buzzsprout, Captivate, Chartable, “EmpireStreaming” (now Soundstack), Libsyn, PodBean, Podtrac, Simplecast, and “Anchor” (now Spotify Creator Studio).

    Somethin'Else, the podcast and radio producer bought by Sony Music Entertainment in 2021, is to pull out of making 18 different radio shows for the BBC. The Media Podcast reported that other programme producers have also pulled out, saying that BBC production budgets - at a reported £800 for a two-hour music show - are too small to be viable.

    The regulation says it applies to all streaming services that operate in Canada, not those physically based there. We're asking the CRTC what an "online streaming service" is (Apple Podcasts? or Wondery?); and what "operating in" means (employees in Canada? or content available there?). We're also asking what sanctions are liable should a company not register by Nov 28. The CRTC has not responded to a request made over 24 hours ago.

    Buzzsprout has posted its network statistics for November. The only regularly released IAB-compliant numbers, the numbers show a slight drop for Apple Podcasts (now 38.2% of all downloads), and a smaller rise for Spotify (up to 26.6%). Google Podcasts is the third largest podcast app, with 2.7% of all downloads.

    Podcast host Ausha has achieved IAB certification. The company was already following the ACPM guidelines, one of the two French podcast audience measurement organisations. Ausha's press release includes an infographic explaining what an IAB download is.

    The Samsung Free podcast app will "soon be updated", according to a communication from Acast to its podcasters, to remove the cause of a significant increase in downloads from automatic plays. (See yesterday's Tech Stuff for more). In the meantime, Acast has demonetised listens coming from the Dalvik useragent "to protect our advertisers"; and notes that "under IAB guidelines, these listens are considered valid". (Also considered valid downloads: those podcast plays bought in games apps)

Rather than being $45,000 for certification for an IAB member, new certification costs $12,500, with renewals costing $6,250. We've updated the original piece.

    Those purchased podcast plays are all OK, it seems. After yesterday's news that iHeartMedia and others have been purchasing podcast plays in game apps, Podtrac tells us: "We decided not to filter these downloads as they are consistent with the latest IAB guidelines. It’s our understanding they appear as browser traffic without a unique user agent (or [unique] IP address). These downloads don’t have a material impact on the publisher rankings including the rank order of the top publishers."
September 28, 2022:
    Players get game tokens if they listen to a podcast for just twenty seconds. (Carman posts a graphic). But, because more than 60 seconds of audio are downloaded by the player, as demonstrated in this article in Sounds Profitable, these plays count as an IAB-certified download from podcast hosts and in prefix services like Podtrac. That allows podcasts promoted in this way to charge for the ads delivered in the show, and for that traffic to be counted in rankers.

    While yesterday's IAB #concernedpodcasters document was heavy on the concerns and light on any solutions, we're reminded of this work for podcast listening using ULIDs, from Dan Benjamin and Dave Jones, which potentially fixes any issues around download analytics. It is a straightforward suggestion to append a random string to the audio request.

    Dan Moren, a former Macworld journalist, writes in Six Colors that "Apple Podcasts reliability problem is turning into an image problem", citing ongoing issues with the app not listing some episodes for podcasts. "I haven’t seen any direct acknowledgment from Apple about this issue over the last two months, much less any indication of what went wrong and how it plans to fix it," he adds, and says "it’s started to feel uncomfortably like Apple doesn’t care about podcast creators livelihoods". (Podnews has repeatedly asked for statements and an interview with Apple).

    The June 2021 US Podcast Report is out from Triton Digital. Stitcher are #1 for a second month, beating NPR (though iH eartRadio isn't measured). Average weekly downloads for the top 10 publishers were up by 5% year-on-year, in spite of an Apple Podcasts auto-download bug and a shift to IAB v2.1. (One investment analyst recently used figures from the competing Podtrac ranker to claim podcasting was in negative growth).

    Stitcher Media is the new #1 podcast publisher in the US, according to the latest Triton Digital US Podcast Report for the four weeks ending May 30. The company, owned by SiriusXM, beat NPR for both average weekly downloads and listeners. NPR News Now is still the #1 podcast, though. It's the first to be compiled to v2.1 of the IAB Podcast Technical Guidelines: the result is a reduction in average weekly users by around 5% for the top 5 publishers. The ranker measures participating publishers only; iHeartRadio owns Triton Digital, but it is not included in the ranker.

    Play just one second of a podcast on Spotify, and you've downloaded over 90 seconds of audio - enough to count as an IAB certified podcast download. Writing in Sounds Profitable this week with Claritas, Bryan Barletta concludes: "podcast streaming is a myth". A fascinating deep-dive into listener-initiated downloads and player-initiated downloads - worth getting it every week.

    The IAB tell us that the public comment period for their updated v2.1 podcast measurement guidelines is now extended until March 17. The first update of these guidelines since 2017, we'd recommend you review them; given our story yesterday you might want to confirm your feedback has been received.
March 2, 2021:
    The IAB Tech Lab released two updates to its v2.1 Podcast Measurement Guidelines for public comment in December and January. However, Podnews can reveal that over the entire 74 days, the public feedback email address given didn't actually work: emails silently bounced with a User Unknown error. The IAB described this as "unfortunate", but would neither confirm nor deny that it has received no feedback at all to this address as a consequence.
February 19, 2021:
    The IAB quietly released an update to their proposed v2.1 Podcast Measurement Guidelines at some point in January for public comment. There was no announcement, and the IAB appear to have removed their previous v2.1 proposal from the web: we kept a copy, though, and have done a diff of it. It now contains guidance for IPv6 measurement, and updated US-based podcast player market share. The public comment period has already ended.

    At some point recently, Google Podcasts has switched its URL structure for individual podcast episodes. If you care, it's now… /feed/:rssuri/episode/:guid where the two variables are BASE64-encoded. (What if every app and service supported this basic link pattern?)
January 4, 2021:
    Parler, the 'free speech' social network, appears to be auto-downloading all podcasts in full on their website, according to Podnews analysis. These downloads aren't IAB compliant, and should be disregarded to comply with certification. (Podcast hosts can only spot these using a check on the referrer, which few actually do).

    The Feed from Libsyn has unveiled the latest data from Libsyn's network, claiming Apple Podcasts was still #1 with 64.5% of all mobile downloads in November. The data relates to mobile downloads only, and the company tells us that these are not based on IAB certified downloads.

    Exclusive: Podcast host Captivate will announce later today that they have achieved IAB Certification for their podcast analytics. The certification was achieved at an "unprecedented pace" according to CEO Mark Asquith, and podcasters will see no significant changes to their reported download numbers. The first UK company to undergo this work, Captivate joins another 10 retail hosts that are certified compliant. (Podnews's Editor is on Captivate's advisory board).
May 15, 2020:
    Podcast host Captivate have added unique listeners to their analytics. Calculated to the IAB v2 standard, they highlight it as "part one of an analytics upgrade". (Disclosures)

    The numbers also come with a note: "In January, most publishers experienced a drop in UMA (Unique Measured Audience) with a simultaneous increase in downloads. This divergence was precipitated by a popular podcast app providing less-specific User Agent data on which the IAB UMA algorithm relies. Podtrac is currently working on a refinement to the UMA algorithm to address this issue."

    Is it possible to become the #2 podcast even if you're not available on podcast apps? A new Australian Podcast Ranker has been released, and the #2 podcast is "Sky News - News Bulletin", audio which is only available on smart speakers (though we found this listing). Similarly, "Fox Sports Audio Bulletin", at #9, is a smart-speaker exclusive. These are both pieces of on-demand audio delivered via RSS, so it's still a "podcast" to the IAB's definitions (and that of Commercial Radio Australia, which runs the ranker): but shows the high level of use of these daily bulletins on speakers.

Produced by research company Kantar, their 'about' page contains details of how it works; it uses IAB v2 compliant data (but, unlike Triton Digital's rankers for LATAM, Australia, and their forthcoming US ranker, is not IAB certified).

Already signed up are NPR, Entercom (inc Cadence13, RADIO·COM and Pineapple Street Media), Stitcher and Cumulus Media (inc Westwood One). The company is already producing a ranker in Australia, the Netherlands and Latin America, and has been producing a ranker for online radio for some time; Triton Digital uses logfiles to produce IAB certified data.

    In France, media research company Médiamétrie will start measuring podcasts on January 1. Like radio measurement in some countries, the company will use a small electronic gadget known as a "portable people meter"; podcasts will need to be watermarked with an audio code; and panelists will need to plug both their headphones and their phone into the meter for it to register. (That won't work with Bluetooth). The company admits it has yet to approach independent podcast producers, preferring to talk to its current clients in radio and television. It has also worked on its own download guidelines to rival the American IAB's.

    Russo also said that Triton Digital will voluntarily resubmit certification to the IAB every two years. "Just like we do on the streaming side, we have an audit team that works with the publishers, who work with the hosting companies and the CDNs and annually audit them to make sure that the quality is kept very high. You may not know this but IAB certification is a one-time only deal. As soon as you get certified, you never have to do anything. But: Triton Digital will volunteer to be recertified every two years."

    Commercial Radio Australia has unveiled the Australian Podcast Ranker, a look at "Australia's top 100 downloaded podcasts", accounting for 10m downloads in September. The ranker uses IAB v2 measurement, and consists of consumption by Australian consumers only. The ABC is to join in the next few months: and "all podcast producers with Australian and international content are invited to participate." Podcast One's Hamish & Andy is the #1 podcast according to the ranker.

    Spreaker's analytics are now using an IAB Certified analytics platform. The change occurred on Monday: the company now uses the platform also used by Voxnest's Audience Network, which achieved IAB Certification in May. Confusingly, Spreaker had been announced as IAB Certified in the final Spreaker Live Show, but this was, we discover, not actually correct. Spreaker customers will see significant changes to analytics, as the company trailed earlier this month.

    Exclusive: The amount of listening to podcasts on the web is increasing, according to new data supplied to Podnews by Simplecast. The data represents all Simplecast shows, and shows plays from Google Podcasts and Apple Podcasts on the web. "Many podcast hosts would just credit 'web browsers' with this data," said Stephen Hallgren, CTO of Simplecast. "But because Simplecast is able to check HTTP referrers, we're also able to see how successful Apple Podcasts Preview is on the web, and how popular Google Podcasts plays are within Google Search. All these metrics are IAB compliant and are reportable through our Audience dashboard."

    Magna predicts slower growth for US podcast advertising revenue, predicting that it'll hit $1bn in 2022. Their report uses data from the IAB, who in June predicted it'll hit $1bn a year earlier. US radio ad revenue for 2018 was $13.4bn, but Magna says that radio revenue will drop by 5% every year from hereon in.

    The IAB in Spain has published a study about internet audio listeners (pdf). A website called "toyoutome" - which inexplicably isn't a fan site of the Chuckle Brothers - reports that - 40% listen to podcasting. The study also compares live vs on-demand - news (80% live, 20% on-demand), and sports (77% live, 23% on-demand).

    Podtrac is changing their measurement algorithm. A blog post appears to indicate that they're undergoing official IAB compliance, and warns "you should expect to see your download numbers decrease to be consistent with the new guidelines". Podtrac claimed last July that their figures were, and have always been, consistent with the IAB Podcast Metric Guidelines v2.0; but say this change is due to "more coalescing around specific interpretations of the guidelines" in the industry.

    Simplecast is in the process of attaining IAB Certification. They join Voxnest/Spreaker, Megaphone, Libsyn, Omny Studio, and ART19. With Blubrry and NPR having already achieved it, that's over a quarter of a million dollars that the IAB has earnt so far from certification. Cough

    Is Marco Arment correct to claim that NPR's RAD podcast analytics is "a privacy violation and a GDPR liability"? In a special article, we looked into podcast apps, privacy and GDPR. In short: no. There's nothing to suggest that RAD is more of a privacy violation and GDPR liability than using a podcast app already is.

    Yesterday, we reported incorrect information about Spotify's measurements, as heard on an industry podcast. Spotify measures a "listen" in a way similar to the IAB's guidelines - as long as you listen for 60 seconds or more, you count. They additionally give "stream starts". (The difference between the two shows how many listeners you lose within 60 seconds). We've updated the post, and our podcast statistics article, and regret the error.
September 24, 2018:

UPDATE: He's wrong. Spotify measures "starts", roughly similar to downloads, and "streams", which measure listens for longer than 60 seconds (the IAB v2 standard).
