How Roku apps work
Roku apps are called channels and are built with Roku's own framework: BrightScript language and SceneGraph components, packaged and distributed through the Roku Channel Store. Both on-demand (AVOD) channels and linear FAST-style channels exist on the platform. Every channel passes Roku's review and certification before publication, and re-certification after significant updates.
Ad formats on the platform
The core monetization unit on Roku is in-stream video: pre-roll and mid-roll ad breaks rendered inside the channel's video player, typically non-skippable 15 or 30 second creatives. Roku's own advertising framework supports standard video ad serving, and many publishers connect third-party demand through VAST tags or server-side ad insertion. Interface-level placements such as pause ads depend on your player implementation and current platform policy.
How advertising is integrated
The documented route is Roku's advertising framework embedded in the channel code, which handles ad rendering, measurement beacons and ad break logic, and accepts standards-based ad responses. Publishers with their own ad stack can use client-side VAST calls or SSAI, where ads are stitched into the stream before it reaches the device. For SSAI on Roku, pay attention to correct measurement firing: client-side beacons must still be reported from the device for impressions to count.
What a publisher should verify
Before connecting demand, verify four things: your channel passes current store certification requirements; app-ads.txt is published and referenced in your store listing; your ad integration fires all measurement events correctly (test with a proxy on a real device, not only in the emulator); and your ad break configuration respects Roku's current policies on ad frequency and content separation. Platform requirements are updated regularly — confirm them in Roku's developer portal before release.
Platform rules change
Every CTV platform updates its store policies, certification requirements and advertising rules several times a year. Nothing on this page replaces the platform's own current documentation: before building or monetizing, confirm the requirements in the official developer and seller portals. If you want an experienced read on your setup, register as a publisher — inventory review comes before any commercial discussion, and terms are agreed individually.
FAQ
Q.Do I need a separate app for Roku?
Yes — each CTV platform has its own app format and store. Some code and all of your content pipeline can be shared across platforms, but the app package and store submission are platform-specific.
Q.What ad format earns the most on CTV?
Non-skippable in-stream video — 15 and 30 second pre-roll and mid-roll — is the standard unit buyers pay for on every CTV platform. Additional UI formats depend on the platform and your app.
Q.SDK, VAST or SSAI — which should I choose?
For on-demand apps, an SDK or client-side VAST is the simplest start. For live and FAST streams, SSAI is the practical standard. The VAST and SSAI page in this hub compares the options in detail.
Q.Is app-ads.txt required?
Practically yes: serious demand sources filter out inventory without it. Publish app-ads.txt and reference it in your store listing before connecting monetization.
Q.Can I run the same ad server across platforms?
Yes — ad serving and SSAI are platform-independent; only the app-side player integration differs. Most multi-platform publishers run one ad stack behind all their apps.
Q.How long does store review take?
It varies by platform and by submission. Plan release schedules with a buffer, and check the platform's current review documentation rather than relying on older experience.
Q.What measurement should I test before launch?
Impression, start, quartile and completion events, plus error callbacks — on real hardware, across the device generations you target. Measurement that only works in an emulator will under-report or be rejected by buyers.
Q.What commercial terms apply?
Revenue share, payout schedule and minimums are agreed individually with each publisher and confirmed in writing before the first campaign. No rates are promised before your inventory is reviewed.
