How to Use CTV Advertising for App Promotion

CTV advertising has evolved into a measurable channel that works seamlessly alongside mobile advertising

Just a couple of years ago, Connected TV (CTV) was seen as a tool for big-budget brand awareness campaigns: impressive in scale, but completely opaque when it came to analytics. It was a channel for reach, not for user installs or targeted actions.

By 2026, the situation has changed dramatically. CTV advertising has evolved into a measurable channel that works seamlessly alongside mobile advertising. The analytical data now available makes it possible to link a TV ad impression directly to an action on a smartphone. Brands and advertisers who have already embraced this tool are seeing tangible results.

Understanding the Terms: Smart TV vs. Connected TV

When discussing television advertising, it’s crucial to understand the difference between two key concepts.

Smart TV refers to a specific type of television. If a device has an internet connection and its own operating system, it’s a Smart TV. The main feature of these TVs is the ability to install apps, open a browser, and use online streaming services directly on the screen, without needing additional devices.

Connected TV is a broader, more comprehensive term. It describes the method of content delivery. CTV is any way of watching internet video on a large screen. This includes:

The Smart TVs we just mentioned;
Game consoles like PlayStation or Xbox;
External streaming devices – Apple TV, Amazon Fire TV, Google Chromecast, Roku;
Modern set-top boxes from internet providers.

Today, mobile apps can be promoted directly through the big screen, using the same programmatic algorithms as mobile advertising. This provides access to a massive audience. According to a Statista study, by the end of 2024, 92% of households in the US owned at least one device with access to CTV. This figure is practically approaching full saturation. However, the primary focus for advertisers now is the European and Asian markets, where the CTV sector is showing strong and steady growth.

Which Mobile App Niches Benefit Most from CTV?

Games. Gamers actively use consoles and streaming services. For promoting mobile games, CTV offers a chance to showcase gameplay in high definition.
Streaming Services and Online Cinemas. This is advertising in the context of consumption. It doesn’t annoy users but offers a solution relevant to what they are already doing.
E-commerce and Shopping Apps. The big screen acts as a storefront. It allows for a detailed display of products and their benefits, motivating users to pick up their phones and complete a purchase.
Smart Home. People who have already purchased a Smart TV are typically interested in other gadgets. Advertising apps for smart home management finds a fertile ground within the CTV ecosystem.
Fitness, Health, and Education. This type of content is perfectly suited for a large screen. Workout videos, English lessons, or meditation sessions feel natural to watch on TV.

The End of the “Reach-Only” Era?

For a long time, the main “pain point” of CTV was the inability to prove its direct impact on sales. Marketers could see impressions and reach, but they couldn’t determine if those impressions led to an app install, a purchase, or a subscription. There was no link to a specific device.

For performance teams, this automatically made CTV a low-priority item in the media plan. Why allocate a significant budget if you can’t calculate the ROMI?

The situation began to change as big data penetrated the CTV ecosystem. Smart TV manufacturers, streaming platforms, and internet service providers started providing identifiers and signals at the household level.

Combined with cross-device matching technologies, this made it possible to track the customer journey:

A user sees an ad on TV;
Some time later, they complete a targeted action on their smartphone.

This was a game-changer for the industry: CTV transitioned from being just a reach channel to a performance tool with transparent analytics.

CTV Inventory Expansion

Another factor accelerating CTV’s shift into a measurable channel is the explosive growth of ad inventory. Previously, choices were limited to a couple of premium streaming services. Now, the landscape is much more diverse:

Smart TV manufacturers (OEMs);
Major streaming platforms and FAST channels (Free Ad-Supported Streaming TV);
Cable providers with digitized offerings;
Game consoles.

This variety makes it possible to scale advertising campaigns without sacrificing quality. Advertisers can buy premium placements and more affordable inventory simultaneously, managing everything within a single programmatic platform.

Attribution in CTV

Ad platforms (DSPs) with a historical focus on mobile promotion have a unique advantage. They have spent years honing their skills with mobile IDs, probabilistic models, and attribution. They understand conversion windows and incrementality.

Therefore, when CTV inventory became available for programmatic buying, mobile-first platforms were the quickest to adapt. For advertisers, this means a seamless integration: one partner, a unified data layer, and a shared optimization logic across both channels. No more manual reconciliation of reports from different systems – everything works in sync.

The main breakthrough that placed CTV alongside classic performance marketing is cross-device attribution.

Marketers can now find answers to key questions.

Did the TV ad lead to an app install?
Did it increase the likelihood of a purchase?
Did it help re-engage “lapsed” users?

Technically, a CTV attribution system uses a combination of data.

Deterministic identifiers (logins, device IDs);
Household-level signals (IP address);
Device graphs that “know” a TV and a smartphone are in the same home.

Because a TV is stationary while a phone can move between networks, linking to the household IP address is considered the most reliable method. Modern platforms, like Kochava, build specialized graphs (such as DeviceLink) to connect devices within a single home. This allows for correct attribution even if a user sees an ad on TV but downloads the app later while on a different network, for example, at work.

CTV Advertising Strategy

To prevent CTV and mobile advertising from cannibalizing each other’s budgets and instead work synergistically, it’s important to follow a few guidelines.

Define Channel Roles. CTV is best for creating demand and building intent. Mobile advertising is the ideal tool for capturing that intent and driving conversions.
Build a Sequential Funnel. An effective approach is: broad household reach via CTV, followed by retargeting on mobile devices to guide users toward the desired action.
Manage Frequency. Without frequency capping, CPMs rise quickly, and users can become overexposed. Set frequency limits, or “caps,” at the household level and ensure your mobile ads aren’t shown to users who have already received excessive TV exposure.
Leverage Contextual Signals. In the world of CTV, accurately identifying a specific viewer is challenging, as one screen is often shared by a whole family. Therefore, environmental signals become paramount: content type, time of day, program genre, and device characteristics. Modern DSPs build machine learning models that interpret these signals to estimate the probability of an install.
Mix Your Inventory. Combine premium streaming apps with more affordable FAST channels and cable networks. The key is to maintain control over ad costs and frequency.

In Conclusion

CTV has come a long way to become a measurable user acquisition tool. With the development of cross-device attribution and the increase in available inventory, it has become a full-fledged part of the performance marketing mix.

However, the effectiveness of advertising here directly depends on how smoothly all parts of the chain – DSP, SSP, and MMP – work together. The higher the quality of signal transmission and the deeper the integration, the more accurate the attribution and the clearer the role of television in your sales funnel. When combined, CTV and mobile advertising unlock even greater potential as powerful drivers for lead generation and business growth.
