How AVOD Works: Ad-Supported Video on Demand Explained

By Sampath Mallidi, CEO of Revidd · Last updated June 2026

AVOD (Advertising Video on Demand) is a streaming model where viewers watch on-demand content free, and the operator earns by selling the ads shown in that content. The platform marks ad breaks, an ad system fills them, and revenue scales with watch time, audience size, and the price advertisers pay per thousand views (CPM).

TL;DR: AVOD trades per-viewer revenue for reach. You earn less per viewer than a subscriber pays, but you can reach many more viewers for free. Revenue is driven by four levers: watch time, audience size, ad fill rate, and CPM. A focused, well-defined audience earns a higher CPM than a generic one, so AVOD rewards both scale and specificity.

This guide covers how AVOD makes money, what drives revenue, how ads are actually inserted, and when it is the right model, with the specifics of how it runs on a real platform.

How AVOD Works to Make Money

Understanding how AVOD works starts with the money flow: AVOD makes money by selling the ads shown to viewers, with revenue equal to roughly the number of ad impressions multiplied by the CPM. More watch time and more viewers create more ad inventory to sell, which is what grows revenue.

The chain is simple: viewers watch free content, the platform inserts ad breaks, an ad system fills those breaks from advertiser demand, and the operator keeps a share of the ad spend. Because it is free to the viewer, AVOD trades per-viewer revenue for scale. According to the Interactive Advertising Bureau, connected TV and ad-supported streaming keep attracting larger ad budgets, which is why AVOD has become a serious revenue line rather than a fallback.

One practical point most explainers skip: the ad fill rate (how much of your inventory actually sells) often matters as much as CPM. A high CPM on inventory that only sells 40 percent of the time underperforms a moderate CPM that sells out. This is why the demand connections a platform brings, and how it handles unsold slots, directly affect what you earn.

What Drives AVOD Revenue?

AVOD revenue is driven by four things: total watch time, number of viewers, ad fill rate, and CPM (the price per thousand ad impressions). Improving any of these increases earnings.

• Watch time: more hours watched means more ad breaks and more inventory.

• Audience size: more viewers multiply the available impressions.

• Fill rate: the percentage of ad slots actually filled with paying ads; unsold slots earn nothing (an ad filler avoids dead air but does not pay).

• CPM: higher when the audience is well-defined and valuable to advertisers, which is why a focused, themed service earns more per impression than a generic one.

This is why AVOD rewards both scale and specificity: a large audience gives volume, and a clear audience gives a higher price per impression.

How Are Ads Inserted in AVOD?

Ads are inserted at marked points in the video, most reliably using server-side ad insertion (SSAI), which stitches ads into the stream so they play smoothly and are harder to block. The points where ads can go are marked using the SCTE-35 standard.

The flow: the content is marked with ad break points, an ad system requests ads from advertisers when a viewer reaches a break, and the ads are inserted and played, then the content resumes. A platform needs proper ad-insertion support and connections to ad sources for AVOD to work; see our explainer on what SCTE-35 is for the marking side.

Here is how this works in practice on Revidd, which is the part generic explainers leave out. Ad breaks are signaled with SCTE-35 markers; ad serving runs through the Google IMA SDK and Google AdMob using VAST tags (the IAB ad standard), so you plug into real programmatic demand rather than a closed network. For FAST channels, Revidd adds an Ad Filler Playlist: when a slot goes unsold, it plays filler instead of dead air, which protects the viewer experience while you work on fill rate. The takeaway for an operator is that AVOD revenue is not just "turn on ads", it depends on standards-based insertion (SCTE-35 plus VAST) and real demand connections, which is what separates a monetizable service from one with empty ad slots.

When Is AVOD the Right Model?

AVOD is the right model when your goal is maximum reach, your audience is large or growing, and you want to remove the price barrier entirely. It suits ethnic and diaspora channels building the widest possible audience, news and information content, and any library that benefits from being free.

AVOD also pairs naturally with FAST channels, which are AVOD applied to linear streaming, and it works well as a free tier that feeds viewers toward subscription or pay-per-view. Many broadcasters run AVOD for reach and layer SVOD or TVOD on top for revenue depth.

A concrete example of the pattern: a diaspora entertainment channel launches free AVOD to gather the largest possible community, since price is the biggest barrier for that audience, then introduces a subscription tier for premium series and pay-per-view for special live events. The free tier does the audience-building; the paid tiers capture the most engaged. This is exactly how Revidd customers like Wi-Flix combine SVOD, AVOD, and pay-per-view in one platform. Our SVOD vs AVOD vs TVOD guide covers how to combine them, and our FAST channel guide covers the linear version.

Launch an Ad-Supported Service

Now that you know how AVOD works, the practical question is execution: free, ad-supported content only earns when ad insertion is standards-based and connected to real demand across every device. If that is your goal, book a demo and we will show how AVOD and FAST work together on one platform.

FAQ

What does AVOD mean?
AVOD stands for Advertising Video on Demand. It is a streaming model where viewers watch on-demand content for free and the operator earns revenue from advertising shown before, during, or after the content.

How does AVOD generate revenue?
By selling the ads shown to viewers. Revenue depends on the number of ad impressions (driven by watch time and audience size) and the CPM, the price advertisers pay per thousand impressions. More viewing and a more valuable audience mean more revenue.

What is the difference between AVOD and FAST?
AVOD is ad-supported on-demand content that viewers choose. FAST is ad-supported linear content on a fixed schedule. FAST is essentially AVOD applied to a scheduled channel; both earn from advertising.

What drives how much AVOD earns?
Total watch time, audience size, ad fill rate (how many ad slots are sold), and CPM. A large audience provides volume and a well-defined audience commands a higher price per impression, so both scale and specificity matter.

How are ads inserted in AVOD?
At ad break points marked with the SCTE-35 standard, most reliably using server-side ad insertion (SSAI), which stitches ads into the stream so they play smoothly and resist ad blockers. The platform connects to ad sources to fill the breaks.
