As brands navigate an increasingly fragmented digital landscape, a growing debate is emerging across marketing teams: how does Connected TV (CTV) compare to affiliate marketing in driving performance?

While both channels continue to attract significant investment, they operate at different points in the funnel — and are increasingly being evaluated through different lenses.

A Tale of Two Models

Affiliate marketing has long been considered one of the most efficient forms of digital advertising.

The model is straightforward: advertisers pay only when a measurable outcome occurs, typically a sale. This performance-based structure has made affiliate a reliable channel for bottom-funnel conversion, with reported returns often ranging between 6x and 15x return on ad spend (ROAS).

CTV, by contrast, follows a more traditional media buying structure. Advertisers pay for impressions, not outcomes, and campaigns are typically evaluated using a broader mix of performance and brand metrics.

Despite these differences, both channels continue to grow.

U.S. affiliate marketing spend is projected to reach approximately $13 billion, while CTV advertising is expected to exceed $38 billion, reflecting a faster rate of adoption in streaming environments.

Efficiency vs. Influence

The core distinction between the two channels lies in their role within the customer journey.

Affiliate marketing is primarily a demand capture channel. It performs best when users are already in-market — searching, comparing, and ready to convert.

CTV, on the other hand, is increasingly viewed as a demand creation channel.

Delivered within premium, long-form content environments, CTV advertising reaches users in a more engaged, less distracted setting. While it does not typically generate immediate clicks, it often influences downstream behavior.

Consumers exposed to CTV ads may later:

• search for a brand

• visit a website directly

• engage with retargeting campaigns

• convert through another digital channel

This delayed-response dynamic has historically made CTV more difficult to measure — but not necessarily less effective.

Measurement Remains a Key Challenge

One of the primary barriers to broader CTV adoption has been attribution.

Affiliate marketing benefits from clear, linear tracking: a click leads directly to a conversion, enabling straightforward reporting and optimization.

CTV attribution, by contrast, involves multiple touchpoints across devices and timeframes.

According to industry surveys, more than 50% of advertisers indicate a need for improved measurement in CTV, particularly in tying ad exposure to downstream revenue.

However, despite these challenges, a large majority of marketers report positive outcomes. Studies indicate that 97% of advertisers using premium CTV believe it contributes to improved ROI performance, particularly when evaluated within a broader media mix.

Shifting Budgets Reflect Broader Trends

The rapid growth of CTV is closely tied to changes in consumer behavior.

Streaming now accounts for a substantial and growing share of total television viewing, reaching nearly half of all U.S. TV consumption in recent measurements. As audiences continue to shift away from traditional linear TV, advertising dollars are following.

Industry projections suggest that CTV is on pace to surpass traditional TV advertising spend within the next several years, driven by ongoing investment from both brand and performance marketers.

Affiliate marketing continues to grow as well, though at a more moderate pace. The channel faces increasing competition, along with structural challenges such as:

• evolving privacy regulations

• declining reliance on third-party cookies

• increased saturation among publishers and affiliates

• changes to commission structures on major platforms

A Converging Landscape

Rather than replacing one another, CTV and affiliate marketing are beginning to converge.

Several emerging trends highlight this shift:

• Shoppable CTV formats, including QR-enabled ads, are increasing in adoption

• Retail media networks are integrating first-party purchase data into CTV targeting

• Influencer and creator partnerships are moving toward performance-based compensation models

• Programmatic CTV platforms are optimizing campaigns toward outcomes such as conversions and ROAS

These developments suggest a hybrid model is taking shape — one that combines the reach and impact of video with the accountability of performance-based marketing.

Implications for Advertisers

For brands, the distinction between demand creation and demand capture is becoming increasingly important.

Affiliate marketing remains a highly efficient tool for converting existing intent.

CTV, meanwhile, is gaining traction as a channel capable of generating new demand at scale.

Used together, the two channels can create a more complete system:

• CTV builds awareness and intent

• Affiliate and other digital channels capture and convert that demand

This integrated approach is becoming more common as brands seek to diversify their acquisition strategies and reduce reliance on any single channel.

Looking Ahead

As measurement capabilities continue to improve and media consumption habits evolve, CTV is expected to play a larger role in performance marketing strategies.

At the same time, affiliate marketing is likely to remain a critical component of the lower funnel, particularly for brands focused on efficiency and direct response.

Rather than competing directly, the two channels appear to be moving toward a more complementary relationship — one that reflects a broader shift in how marketers think about performance, attribution, and growth.

In that context, the question is no longer which channel performs better.

It is how each contributes to the overall system driving customer acquisition.
