Sideloaded CTV Apps: Pixalate study finds traffic coming from apps not in official Amazon Fire TV app store almost doubled over the first three quarters of 2022 compared to previous year

Global Connected TV (CTV) programmatic ad spend continues to soar, rising 32% year-over-year, according to Pixalate’s latest estimates. However, this rapid growth also raises concerns regarding the apps on which these ads appear.

One of the most underreported challenges relates to “sideloaded apps,” which are apps that are downloaded and installed via an alternate means, instead of the device’s official app store. This is an area advertisers need to pay particularly close attention to, especially on Amazon Fire TV devices, which allow sideloaded apps.

Key Takeaways from Pixalate’s Q3 2022 Sideloaded CTV Apps Report

  • Amazon Fire TV is the most impacted Android TV platform. We saw video ad impressions served on sideloaded apps almost double over the first 3 quarters of 2022 compared to the same period in 2021, with more than half of those impressions coming from Amazon Fire TV devices.
  • Sideloaded apps may be a brand safety risk since they can contain content that may have been barred from the platform’s official app store - including pirated content.
  • The presence of ad traffic on sideloaded apps may reflect that app-ads.txt is not being sufficiently used on CTV programmatic advertising.
  • Sideloaded apps may also be used to deliver malware and as bots to perpetuate ad fraud.

Pixalate has published the list of the top 25 most popular sideloaded CTV apps, based on programmatic ad volume in Q3 2022.

In our September 2022 report - “CTV’s Bundle ID Crisis”  we described the problematic state of Bundle IDs in the CTV ad ecosystem and how we map them to various platforms. Identifying traffic directed to apps that are not part of the app store is also crucial. In fact, sideloaded apps are factored into our Amazon Fire TV Seller Trust Index, in which we introduced a new score category (Sideloaded Score) in 2021.

What is a sideloaded app? 

A sideloaded app is an app from an unofficial and unmoderated location that can be manually added to various CTV platforms by a user. According to Pixalate’s data, this is primarily done on CTV platforms that are based on an Android operating system.

Pixalate has been tracking these kinds of apps since last year, when we noticed apps that did not have an app store presence on a specific platform but appeared to be real in every other way. But these apps are potentially unsafe as described in the next section, which is why we worked on a methodology to regularly track and identify these apps - 

  1. We defined a sideloaded app as an app/apk that does not have an associated official store and is not a part of the official store of the CTV platform identified.
  2. The app is identified either by the Bundle Id passed in the bid stream or detected by proprietary technology of Pixalate.
  3. We use our Bundle Id mapping technology to identify Bundle Id similarities or app name similarities associated with these sideloaded apps.
  4. These apps are regularly reviewed for their validity, and also to better support some of the “Closed Network Apps” described in the next section.

Why are sideloaded apps an advertising problem?

While there are a few legitimate use cases, the common reasons a user may install a sideloaded app are to access an app that may not have been made available on that platform’s app store, or to access free content which is oftentimes pirated, and usually unmoderated. Advertisers typically do not want their ads adjacent to illegal pirated content. They also do not want adjacency with unmoderated content that may not be brand safe.

Beyond that, since the apk files for the sideloaded apps are unmoderated, they may contain additional packages that operate in the background and have unexpected behaviors, including malware and bots that generate fraudulent ad traffic.

One of the legitimate scenarios we want to highlight is what we call “Closed Network Apps.” These are custom apps that are manually added to a CTV platform by a publisher/company that has direct relationships with publishers for content, and sells these devices/apps preloaded to users/businesses. Examples could be CTV sets that are set up in grocery stories, restaurants and other businesses that show music videos, sports, etc. These require additional due diligence to check the validity of the content as well as inventory/target audiences.

A note about sideloaded apps and app-ads.txt

One of the interesting aspects of seeing advertising on sideloaded apps (especially those that are not just ports of existing valid apps from other Android platforms) is that sideloaded apps do not have any app-ads.txt. This is because app-ads.txt requires an app store presence. This is interesting because it appears that there is a lot of traffic where sellers are not being verified. 

CTV device types impacted by sideloaded apps

Amazon Fire TV devices are powered by an Android-based operating system, which makes it relatively easy for consumers to install other Android-based apps on the CTV devices (for example, apps from their phone). This is also true of other Android-based operating systems. 

Pixalate has seen sideloaded apps across 100+ CTV platforms, but Amazon Fire TV is one of the more popular ones and is likely why it appears to be a common device used for sideloading apps. In Q3 2022, we saw over half the video impression ads served on sideloaded apps coming from Amazon Fire TV devices.

Here are the top five device platforms we have seen impacted by sideloaded apps (based on programmatic ad impressions, as measured by Pixalate): 

  1. Amazon Fire TV
  2. Mxq
  3. Nvidia
  4. Tanix
  5. H96

Top Sideloaded Apps (across all platforms)
