What is OTT Advertising?
OTT advertising is a form of digital video advertising delivered through internet-connected devices, bypassing traditional cable or satellite TV providers. Over-the-top advertising allows your brand to reach customers directly through streaming devices and services. It helps you target a unique audience or a specific market segment via OTT channels.
OTT advertising represents an exciting opportunity to increase customer engagement across multiple channels while maximizing your advertising return on investment.
The number of OTT platform adopters has skyrocketed in recent years. As users pile on to find new content from OTT services, the number of active users on these platforms has now exceeded the US population.
As of 2025, the global OTT user base has reached approximately 5.27 billion, with the OTT video advertising market projected to generate $207.22 billion in revenue this year.
What are the benefits of OTT Advertising?
OTT advertising has taken over traditional TV as millions continue to migrate from traditional Pay-TV operators. As more and more people flock to newly launched OTT channels, it is imperative that you incorporate OTT advertising into your digital marketing plan to target a niche audience more effectively and minimize ad spend waste.
Here are some of the major benefits of advertising through OTT platforms:
Improved targeting
OTT platforms leverage analytics and in some cases artificial intelligence by curating content enabling advanced audience targeting and better monetization.
A greater number of ads does not necessarily mean higher revenue. You have to be targeting the right pool of customers for effective monetization. Through better segmentation (and more segments to analyze), OTT channels can identify people that are more likely to click on your ads for a product or business, building brand awareness and driving higher conversions..
Better Engagement
Unlike traditional TV ads, OTT advertising inserts ads in the right places and for short spaces between movies and shows, for which the audiences are much more inclined to sit through. Users can interact with the ads more effectively, and you can even lead them to your product and services page if they choose to click on the relevant links.
Shorter, engaging ads are sometimes more effective for ad recall. A study by the World Advertising Research Center showed that 30-second spots are ideal for a good brand-building television commercial, in that it is sufficient time to make an emotional and intellectual connection, but not so much as to lose interest.
Some studies also suggest that short ads bring almost as much engagement as the longer ones. The Journal of Advertising Research published a study that states that 7-second ads were almost as effective as 15-second advertisements and 60 percent as effective as 30-second advertisements.
Attractive Prices
OTT advertising allows you to reduce ad spending because you do not pay for ads ‘real-estate’ on print media or outdoor digital signages. Nor do you waste time and money targeting the wrong audience through short TV ad windows.
OTT advertising allows for a more specific and targeted advertising approach by tracking key metrics allowing you to better understand the relative performance of your advertising campaigns. These metrics let you understand audience preferences so that you can further streamline ad spending and reallocate resources as needed.
Geographical/ Device Independence
Audiences are increasingly leaving regular broadcast TV networks for OTT services delivered over the internet and accessible via mobile devices. “Viewers are no longer tied to broadcast schedules or single-location TV setups, thanks to streaming access across mobile devices, smart TVs, and web apps. OTT platforms thus eliminate the limits of broadcast entertainment services that use cables and wires.
The advanced user analytics provided by OTT platforms lets you target users based on their locations and device preferences. You can then focus your advertising strategy on those parameters for better results and decreased ad spend.
Uninterrupted Ads Serving
Traditional viewing experiences can be interrupted by unexpected events such as network disconnections, signal issues, and power outages, especially in developing countries. Rigid TV schedules for broadcasting shows at certain times of the day limit viewers from accessing content at any time. In contrast, OTT platforms bring more accessibility and engagement, which means uninterrupted ad serving.
Popular examples of OTT advertising platforms
There’s no shortage of powerful OTT platforms offering ad inventory to brands of all sizes. But choosing the right one depends on your budget, targeting goals, and desired audience reach. With the rise of hybrid monetization models and ad-supported subscriptions, advertisers now have more control, precision, and scale than ever before. Let’s explore five of the most relevant and high-performing OTT advertising platforms in 2025:
1. Netflix
Netflix’s ad-supported tier has seen rapid adoption (users average 41 hours/month) since its late 2022 launch, with over 94 million monthly active users globally by mid-2025. Nearly half of new U.S. subscribers are now opting for this ad plan, which costs around $7.99/month and includes mid-roll and pause ads, with more interactive formats on the way. Netflix’s advertising business is booming, projected to grow by 43% this year, with $2 billion in ad revenue expected, and a goal of doubling that figure by year’s end.
2. Disney+
Disney+ joined the ad-supported trend in 2024, launching a lower-cost ad tier alongside its premium subscription. The platform appeals to family and fandom-oriented audiences, and its unified Disney+ /Hulu/ESPN bundle allows for cross-platform ad campaigns that span both on-demand and live content. While Disney has not disclosed ad-tier user counts, analysts expect Disney+’s ad revenue to trail only Netflix, with a growing share in 2025.
3. Peacock
Peacock, NBCUniversal’s streaming platform, now reaches 286 million users monthly across its network and boasts 41 million paying subscribers, all thanks to its strong ties to sports, news, and live event programming.
Peacock’s ad model includes a free tier with limited content and ads, a Premium tier with full access and ads, and a Premium Plus tier that removes most ads (except on live broadcasts). In 2024, Peacock surpassed $2 billion in advertising revenue, and Q1 2025 ad sales alone hit $1.2 billion.
4. Roku
Roku continues to dominate the U.S. connected TV market, powering over 90 million streaming households and reaching 145 million viewers through The Roku Channel and Roku OS.
Roku accounted for nearly 38% of all programmatic CTV ad impressions in Q1 2025, outperforming Fire TV and other platforms. Through its self-serve Roku Ads Manager, advertisers run precise, data-driven campaigns across Roku’s proprietary channels and partner apps.
5. Amazon
Prime Video alone now has tens of millions of ad-tier users, and Amazon recently secured over $1.8 billion in upfront ad commitments. Amazon’s OTT advertising ecosystem offers multiple touchpoints, including Prime Video’s ad-supported tier, Freevee (a fully ad-supported streaming service), and the Fire TV OS. It might be the most comprehensive OTT advertising suite on the market today.
The cross-platform “Complete TV” suite helps advertisers manage multi-OS CTV campaign delivery, coupled with unified reporting and strong targeting, thanks to Amazon’s vast first-party data.
Terms related to OTT Advertising
You might come across terms such as AVOD, CTV, Linear TV quite often in your research for the best OTT advertising platforms. It is important to know the difference between these to ensure you are moving in the right direction with your advertisement goals. Let’s get right to it!
- AVOD stands for advertising-based video-on-demand, which comprises OTT streaming services that offer customers free, ad-supported streaming video. The most popular examples are YouTube, Netflix, Disney+. AVOD does not promote premium content to its consumers as much as other forms of OTT advertising services. Advertisers should focus on AVOD if their product is consumable by a larger pool of audiences at lower prices.
- CTV is Connected TV that allows devices to connect to the internet to experience OTT services. Users with CTV usually tune into regular broadcast TV and online content. CTV offers users the choice to shave off some of their regular Pay-TV channels and opt for OTT streaming instead.
- Linear TV is the traditional TV viewing experience with scheduled broadcasts. Viewership for linear TV has been steadily declining in recent years.
- Advanced TV or ATV encompasses Linear TV, CTV, and Addressable TV, which is TV connected to the internet for on-demand content.
- SSAI (Server-Side Ad Insertion) refers to stitching ads directly into video streams, ensuring a seamless, buffer-free viewing experience across devices and making ad-blocking less effective.
- SCTE-35 is a standard used to signal where ad breaks occur in a video stream. It helps OTT platforms and broadcasters automate ad placement and dynamic ad insertion across live and on-demand content.
Best OTT Advertising Practices
1. Nail Your Ad Timing Down to the Frame
If there’s one thing viewers won’t forgive, it’s an ad that crashes the party early or barges in late. Frame-accurate ad insertion is essential, especially for live content like sports. Cutting off programming mid-sentence ruins the experience and erodes brand trust.
Use reliable ad trigger mechanisms like SCTE-35 markers or advanced frame detection (e.g., temporal fingerprinting) integrated upstream in your broadcast pipeline. This ensures ads roll exactly where they should, with no spoilers and no stutters.
2. Fill the Whole Ad Break
It’s tempting to focus on targeting and personalization, but don’t overlook the basics: every ad break needs to be fully populated. Empty time slots are a monetization black hole.
Give your Ad Decision Server (ADS) early access to break duration and metadata. Pre-transcode creatives, keep fallback ads on standby, and let multiple ADS engines work in parallel to keep things seamless, especially during high-concurrency events like live matches.
3. Match Ad Format to Device
OTT audiences watch on everything from high-end Apple TVs to outdated set-top boxes. That means your ads need to be not just pretty, but also technically compatible across formats and devices.
Best practice: Standardize your ad creative specs and test playback across all supported platforms. This includes video/audio codec matching, subtitle tracks, alternate audio languages, and UI responsiveness. Build fail-safes into your SSAI logic to recover from glitches without leaving users in the dark.
4. Use One Ad Server to Rule Them All (But Test Like You Don’t)
Using a single ad serving system across your OTT footprint simplifies management, avoids SDK chaos, and makes campaign reporting easier. Each SDK may have different integration requirements, updates, and compatibility issues, leading to increased complexity and potential errors in ad delivery. That said, don’t assume it’ll “just work” on every screen.
Best practice: Centralize ad serving, but run regular compatibility tests per device type. Pay special attention to Smart TVs and set-top boxes, as they tend to be the troublemakers. Also, make sure to integrate ad tech with your OTT backend so ad slots, content metadata, and rights enforcement all speak the same language.
5. Don’t Let Your Ads Break the App
OTT ad tech is often layered on top of complex streaming apps. If your player crashes or glitches when switching between content and ads, you’ll lose both revenue and user trust.
Implement real-time monitoring of playback errors, buffering events, and app crashes—especially during ad transitions. Stress-test edge cases like midstream drops or dynamic bitrate switching under poor network conditions.
6. Treat SSAI Like a Frontline System, Not an Afterthought
Server-side ad insertion (SSAI) works best when it’s deeply embedded in your delivery workflow, not tacked on at the end. The closer you get to the origination point, the more control you have over timing and content alignment.
Sync your SSAI with master control systems and prepare ad manifests in advance. Use aligned chunking and frame-accurate packaging so that SSAI doesn’t have to guess where content ends and the ad begins.
7. Use Metadata to Serve Smarter Ads
Without rich metadata, your targeting is throwing darts in the dark. Good data not only powers better audience segmentation but also smarter ad placement decisions (e.g., avoiding competitor clashes or repetitive spots).
Share contextual metadata—like program type, genre, or live status—with your ad platform. Also, enable frequency capping, category exclusion, and dynamic slot pricing. The more the ADS knows, the better it can optimize for value.
8. Build for Spikes, Not Steady Streams
OTT viewership doesn’t ramp up gently—it spikes. Live sports, new seasons, breaking news—they’ll all push your infrastructure to the limit. That includes your ad systems.
Use cloud-native SSAI and ad decision-making that can auto-scale. Run multiple ADS instances in parallel. And yes, plan for concurrency. A single ADS bottleneck can ruin a thousand viewer sessions at once.
9. Match Ad Load to Viewer Tolerance
Some viewers will tolerate a few ads. Others won’t sit through a second of pre-roll. Understanding that tolerance can be the difference between keeping a viewer and losing them to a competing platform.
Segment audiences based on behavior and device. For example, mobile users might prefer shorter mid-rolls, while Smart TV viewers might tolerate longer breaks. Tailor ad frequency and length accordingly.
10. Measure What Matters, Not Just Playback
Your ad performance, drop-off rates, and engagement patterns are equally critical.
Monitor ad-related QoE metrics like buffering during ads, creative load times, and playback errors. Use A/B testing, heatmaps, and engagement funnels to improve placement and UI. Map ad revenue to content segments to figure out what moves the needle.
11. Don’t Forget the Rewatchers
Time-shifted and on-demand viewers account for a huge share of ad-supported views, but if your ad workflows don’t extend to VOD or DVR, you’re missing out.
Use frame-accurate markers for program and ad boundaries in your live streams. This enables selective ad replacement in binge-worthy content or updated ads in previously aired episodes.
12. Sync Up OTT and Traditional Ad Sales
OTT and linear teams often work in silos, but your viewers don’t care. They just want a smooth experience, and your advertisers want smart reach.
Create ad inventory coordination across linear and OTT workflows. That means unified tracking, shared metadata, and exclusivity rules that apply across platforms. Offer placement-level reporting to attract premium buyers.
How is OTT advertising priced?
Advertisers can choose between many options in the OTT advertising space. Sometimes you need to choose between a steady amount of investment for ads or pay based on different ad spending models listed below. You should carefully consider each of these depending on how much you want to spend and how long you want your ads displayed to make an impression.
- CPM (cost per mille) charges per thousand impressions for one ad.
- CPV (cost per view) lets you pay for each ad view on an OTT platform.
- CPCV (cost per completed view): As an advertiser you are only required to pay for each ad that has been played to the fullest length without users clicking on the ‘skip ad’ option. Some models of OTT streaming bring better engagement if there is no option to skip.
- vCPM (viewable cost per mille) or vCPV (viewable cost per view) measures cost based on how many people see the ad. This option is great for advertisers who are aiming for significant ad impressions during their campaign interval.
- CPH (cost per hour) and CPS (cost per second) are for those who want to spend for the length of impressions made through their ad.
- CPE (cost per engagement) can also be an effective method of measuring the value of ads by the engagement it generates.
How do you get started?
To get started in the OTT advertising space, you’ll have to understand the various OTT platforms and what they offer in terms of advertising inventory. Based on your marketing goals, budget, and other considerations such as your target pool of audience, you can develop and deploy an advertising strategy.
There are primarily two options to choose from:
- Programmatic buying: An automated and real-time method for buying ad space across channels in a particular platform, programmatic buying is meant to simplify the process of purchasing ad space. With the help of analytics, the platform helps you bid for ad space in their inventory. It is also the most effective way of buying because AI tools choose the best price for your investment. The drawback is that you cannot have custom services, platforms, devices, or channel space.
- Direct buying: Works well when you are sure about the type of audience and messaging you want to portray. Direct buying provides increased visibility as far as ad performance is concerned. This will help you figure out what works best over the long term. It will limit your cross-platform advertising but guarantees control.
Once you choose how to advertise, you can design your ads considering the appropriate messaging, length, and placement. In the end, it is essential to measure the impact of your ad and the results of your marketing campaign.
Conclusion
In conclusion, OTT advertising is more than just a trend in today’s entertainment world. It is a powerful channel for marketing. It’s less expensive than traditional advertising and TV because it can target the right customers through better segmentation – if you know your customer, you can spend your marketing dollars with confidence.
There are many advertising services/platforms out there – some big, some small. You’ll have to decide where your marketing dollars should go. Larger service providers like Amazon will have a broader reach in terms of customers (a user base), and smaller, possibly niche services could help you target specific market segments that are more aligned with your marketing goals.
There is no time better than right now to embrace OTT advertising – low competition (for now) and better segmentation means lower costs – and more customers!
FAQ: OTT Advertising
What is OTT Advertising?
OTT advertising means placing ads within content delivered via internet-connected devices—think smart TVs, Apple TV, Roku, and other streaming platforms. Instead of buying space on traditional TV, you’re serving targeted OTT ads to users watching OTT content on streaming services like Hulu, Netflix (if they go ad-supported), or FAST channels. It’s digital video advertising built for the streaming era.
What Are the Challenges of OTT Advertising?
The biggest headaches? Fragmented devices, unpredictable playback behavior, and ensuring your OTT advertising plays on every smart TV or connected TV (CTV) setup out there. Then there’s timing—nobody wants a “peek-through” before the ad rolls. Targeting and measurement are traditionally better than traditional TV advertising, but only if your tech stack is dialed in. Also, keep in mind that smaller OTT services may not provide as rich a dataset as larger ones like Hulu or YouTube.
What Is the Difference Between OTT and CTV Advertising?
OTT video advertising refers to ads shown in OTT content—streamed shows, live sports, or on-demand movies. CTV advertising focuses specifically on connected TVs like Roku, Fire TV, or Apple TV. So, all CTV advertising is OTT, but not all OTT is CTV—OTT also includes phones, tablets, and laptops.
How Effective Is OTT Advertising?
OTT ads can be incredibly effective, especially with completion rates often topping 90%. That’s because people tend to sit through ads on high-quality cable TV-style streaming TV content. Add in granular targeting and better tracking than traditional TV, and you’ve got a strong ROI. As ad spending shifts from cable to OTT services, expect OTT advertising platforms to keep evolving with smarter placements and better outcomes.
