8 min read·Nov 13, 2024

If you’re running ads on streaming platforms, you’ve probably wondered:

  • Are OTT ads better for lead generation?
  • Is CTV worth the higher cost per impression?
  • How do I choose the right platform for my ad budget?

OTT (Over-the-Top) ads work across multiple devices (TVs, phones, laptops), while CTV (Connected TV) ads are full-screen, unskippable, and only on Smart TVs.

But which one actually delivers better results?

In this blog, I’ll break down:
How OTT & CTV ads work (so you don’t waste your ad budget).

5 key differences that affect cost, targeting, and engagement.

How to choose the best option for your business.

What is OTT Advertising?

OTT (Over-the-Top) advertising means showing ads on streaming platforms that people watch using the internet, instead of through cable or satellite TV. 

These ads appear on platforms like Netflix (with ads), Hulu, Amazon Prime Video, and YouTube TV.

Unlike CTV (Connected TV) ads, which only show on Smart TVs, OTT ads can be watched on multiple devices, including smartphones, tablets, laptops, and Smart TVs.

This makes OTT more flexible and allows advertisers to reach people wherever they watch content.

How Does OTT Advertising Work?

OTT ads are delivered through internet-based streaming services and are inserted into content that people watch on-demand. They can appear:

  • Before the video starts (pre-roll ads)
  • In the middle of the content (mid-roll ads)
  • After the video ends (post-roll ads)

Unlike traditional TV ads, OTT ads can be targeted based on user data.

Advertisers can choose to show their ads to specific age groups, locations, or interest groups.

Here are a few types of OTT platforms: 

ModelDescriptionExamples
SVOD (Subscription-Based Video on Demand)Viewers pay a monthly fee to access content, sometimes with ads.Netflix, Disney+, HBO Max
AVOD (Ad-Supported Video on Demand)Content is free, but viewers must watch ads.Hulu, YouTube
Hybrid ModelsA mix of both paid subscriptions and ads.Peacock, Amazon Prime Video

Pros and Cons of OTT Advertising: 

OTT Advertising Pros and ConsWhat It Means for You
✅ Highly targeted ads using audience data.You can retarget users based on their behavior across multiple devices.
✅ Cross-device reach (TVs, phones, desktops, tablets).Your ads can follow users across platforms, improving brand recall.
✅ Lower entry cost than traditional TV advertising.Great for small businesses looking for affordable video ads.
❌ Ad fraud risks (bot traffic, invalid impressions).You need to use fraud detection tools to prevent wasted ad spend.
❌ Ad fatigue due to repetitive placements.Be sure to rotate ad creatives frequently to keep engagement high.

Pros:

  • Precise Targeting & Segmentation: Marketers appreciate the ability to target specific demographics or interests on streaming platforms, which is harder with broad TV broadcasts.
Pros of OTT Advertising
  • Detailed Analytics & Targeting Data
  • OTT campaigns come with digital metrics (views, completions, etc.) that can help advertisers gauge performance and audience response in closer to real-time. 
  • Advertisers can also tap into first-party or third-party data to improve efficiency and attribution in OTT campaigns​.

One Reddit user said-

Pros of OTT Advertising
  • Higher Viewer Attention
  • Viewers tend to stay engaged during OTT ad breaks, and advertisers can manage frequency to reduce over-exposure. 
  • This can make OTT buys more efficient at reaching audiences compared to traditional TV.
Pros of OTT Advertising

Cons:

  • No Click-Through or Immediate Engagement
  • Because OTT ads run on TV screens, users typically can’t click them. 
  • This means OTT campaigns often lack direct interaction (no click-throughs), making success harder to gauge in the short term compared to online banners or social ads.

OTT advertising is a powerful way to reach audiences beyond traditional TV, offering precise targeting, lower costs, and cross-device visibility

However, advertisers need to be mindful of ad fatigue and fraud risks.

In the next section, we’ll explore CTV advertising and see how it compares to OTT.

What is CTV Advertising?

CTV (Connected TV) advertising means running ads on Smart TVs and streaming devices like Roku, Fire TV, Apple TV, and gaming consoles (Xbox, PlayStation, etc.).

  • OTT ads can be watched on phones, tablets, laptops, and TVs, but CTV ads only play on Smart TVs and streaming devices.
  • CTV ads feel more like traditional TV ads because they are full-screen and usually unskippable.
  • Ads appear on streaming platforms like Hulu, Peacock, Tubi, Pluto TV, and ESPN+ while people are watching shows or movies.

How Does CTV Advertising Work?

CTV advertising involves delivering video ads through internet-connected televisions. Here's how it functions:​

  • Ad Delivery: Ads are integrated into streaming content on platforms accessed via CTV devices. These ads can appear before (pre-roll), during (mid-roll), or after (post-roll) the main content.​
  • Targeting: Leveraging data-driven insights, advertisers can target specific demographics, interests, or behaviors, ensuring ads reach relevant audiences.​
  • Interactivity: Some CTV platforms support interactive ad formats, allowing viewers to engage directly with the advertisement, enhancing user engagement.

Pros of CTV Advertising: 

  • High Reach & Completion Rates:  A digital marketer emphasizes that CTV ads can reach a broad audience and that viewers often watch the ads to completion, increasing brand exposure.
  • Advanced Targeting: 
  • One experienced CTV marketer notes that compared to linear television, CTV offers more precise targeting and better reporting/analytics.
  • (They do caution, however, that this comes with higher costs, as discussed later.)
Pros of CTV advertising
  • Inherent Viewability:  
  • In CTV, video completion rates (VCR) and viewability are naturally high because ads play on screen in full. 
  • This Reddit user suggests focusing on metrics like unique reach, ad frequency, and brand lift, since virtually all CTV ads are seen by viewers (making viewability less of a concern than in web/mobile ads).
Pros of CTV advertising

Cons of CTV Advertising: 

  • Not a Direct-Response Channel:  
  • A programmatic buyer with years of CTV experience stresses that CTV works better for upper-funnel goals (like awareness or consideration) rather than immediate sales or lead generation. 
  • Direct conversions from a CTV ad are rare, given the inability to click the ad and the complex path to purchase.
Cons of CTV Advertising
  • Higher Costs (CPM) Than TV: 
  • Many practitioners note that CTV impressions cost more on a per-thousand basis.
  • Advertisers should be prepared to pay a premium for CTV’s targeting and on-demand environment.
  • Platform Fragmentation:  
  • An ad operations expert explains that the CTV landscape is fragmented across devices and apps (Roku, Amazon Fire TV, smart TVs, etc.)
  • The fragmentation introduces complexity in tracking and may require using multiple tools or demand-side platforms to manage a campaign comprehensively.
Cons of CTV Advertising

Knowing the pros and cons makes it easier for advertisers to decide if CTV fits their marketing strategy.
