What is CTV Advertising?

The Nuances of CTV Advertising: Decoding the Difference from OTT Advertising


The world of advertising is ever-changing, and the latest buzzwords in the industry are CTV (Connected TV) and OTT (Over-The-Top) advertising. To the uninitiated, these terms might sound interchangeable, but in reality, they refer to different aspects of digital video advertising. In this article, we will delve into the world of CTV advertising, demystify the difference between CTV and OTT advertising, and discuss why it's essential for advertisers to be aware of these distinctions.

Connected TV Advertising: A Brief Overview

Connected TV (CTV) refers to any television set that can be connected to the internet, either directly or through external devices like streaming sticks, game consoles, or set-top boxes. These internet-enabled TVs give users access to a plethora of content, ranging from subscription-based streaming services like Netflix and Hulu to ad-supported platforms like Tubi and Pluto TV.

CTV advertising is the placement of targeted ads on these internet-connected televisions. The primary goal of CTV advertising is to reach cord-cutters and cord-nevers – people who have either discontinued or never subscribed to traditional cable or satellite TV services. CTV advertising combines the power of digital marketing (granular targeting, data-driven optimization, and real-time measurement) with the immersive experience of television viewing.

The Big Difference: CTV vs. OTT Advertising

While CTV and OTT advertising may seem synonymous, they refer to distinct concepts. To put it simply, CTV is a subset of OTT. OTT encompasses all forms of video content delivered over the internet, bypassing traditional cable or satellite TV distribution. This means that OTT content can be accessed through various devices, including smartphones, tablets, desktops, laptops, and, of course, connected TVs.

On the other hand, CTV advertising is specifically focused on delivering ads to viewers using internet-enabled television sets. Thus, while OTT advertising includes ads on CTVs, it also extends to other devices used to consume digital video content.

Why Understanding the Difference Matters

One might wonder why it is necessary to differentiate between CTV and OTT advertising. The answer lies in the way consumers interact with content and ads on different devices.

Different User Experiences: The experience of watching content on a TV set is fundamentally different from consuming it on a smaller device like a smartphone or tablet. Television offers a more immersive, lean-back experience, while other devices often cater to on-the-go or multitasking viewers. Advertisers need to consider these differences when designing their campaigns and tailoring their messages to suit the medium.

Varied Targeting Capabilities: CTV advertising enables advertisers to access more granular targeting options than traditional linear TV advertising. Advertisers can use a combination of first-party, second-party, and third-party data to create highly customized audience segments. However, the level of targeting precision may differ between CTV and other OTT devices. For instance, mobile devices can provide more detailed location data than CTVs, while CTVs can offer a better understanding of household composition.

Distinct Measurement Metrics: CTV and OTT advertising rely on different metrics to gauge campaign performance. While both use traditional digital metrics like impressions, clicks, and conversions, CTV advertising also incorporates TV-centric metrics like reach, frequency, and gross rating points (GRPs). Understanding these unique measurement methodologies is crucial for advertisers to optimize their campaigns effectively.

Diverse Ad Formats and Inventory: CTV and OTT advertising offer a range of ad formats, such as pre-roll, mid-roll, and post-roll ads, as well as interactive and shoppable ads. The availability and suitability of these formats vary across devices. For example, interactive ads may be more effective on touchscreen devices like smartphones and tablets, while traditional video ads might be better suited for CTVs. Additionally, the inventory available for CTV and other OTT devices can differ, with some platforms offering exclusive ad placements or targeting options on specific devices.

Fragmented Ecosystem: The CTV and OTT ecosystems are highly fragmented, with various platforms, devices, and content providers. Advertisers need to navigate these complexities and partner with the right technology platforms and media partners to maximize their reach and deliver a seamless ad experience. Understanding the difference between CTV and OTT advertising enables advertisers to make informed decisions about allocating their budgets and resources.

Maximizing the Potential of CTV Advertising

To make the most of CTV advertising, marketers should:

Develop a Holistic Video Strategy: Create a comprehensive video strategy that incorporates both CTV and other OTT devices, ensuring consistent messaging and branding across platforms while tailoring the ad creatives to suit each device's unique viewing experience.

Leverage Advanced Targeting Capabilities: Utilize the granular targeting options available in CTV advertising to create highly customized audience segments and deliver relevant, personalized ads to viewers.

Measure and Optimize: Track campaign performance using a combination of digital and TV-centric metrics, and continuously optimize ad placements, targeting, and creatives based on the insights gathered.

Invest in High-Quality Creatives: Given the immersive nature of the television viewing experience, it's essential to invest in high-quality, engaging creatives that resonate with viewers and drive the desired action.

Stay Up-to-Date with Industry Trends: The CTV and OTT landscapes are constantly evolving, with new platforms, ad formats, and technologies emerging regularly. Staying abreast of these developments can help advertisers adapt their strategies and stay ahead of the competition.


CTV advertising presents an exciting opportunity for marketers to reach engaged audiences in the rapidly growing connected TV space. By understanding the difference between CTV and OTT advertising and adopting a strategic approach that takes into account the unique aspects of each medium, advertisers can effectively harness the power of digital video to drive brand awareness, engagement, and conversions.
