Why CTV Belongs in Your Growth Strategy

Ecommerce brands have spent the last decade optimizing paid social, search, and email. But as customer acquisition costs climb and data privacy rules tighten, marketers are running into a wall: the old channels are expensive, saturated, and noisy.

That’s where Connected TV (CTV) comes in.

CTV brings your brand into the living room — with performance-grade targeting, real-time attribution, and storytelling power that rivals traditional TV. Once reserved for enterprise advertisers, CTV is now one of the smartest plays for mid-market and scaling DTC brands.

At Roswell NYC, we’ve seen first-hand how CTV campaigns create measurable lift when layered with retention and performance marketing. But here’s the truth: not all CTV platforms are created equal.

This guide breaks down what CTV is, how to choose the right partner, and how Roswell helps brands turn streaming audiences into measurable revenue.

What Is Connected TV Advertising?

Quick Answer: Connected TV (CTV) is digital advertising delivered through internet-connected televisions and streaming devices such as Roku, Apple TV, Amazon Fire TV, and apps like Hulu or Disney+.

Unlike traditional TV, CTV campaigns use data-driven targeting and real-time measurement, giving ecommerce brands precision, flexibility, and transparent ROI.

CTV combines the storytelling power of television with the accountability of digital performance marketing — making it one of the most effective acquisition and brand channels in 2025.

Typical metrics for ecommerce:

  • CPMs: $15–40 for mid-market tests; up to $50–65 for premium inventory
  • ROAS: ~3.2x average on $10K+ monthly spend
  • Attribution: Cross-device and household-level via IP/device graph matching

Why Ecommerce Brands Are Shifting to CTV

CTV is no longer a “nice to have” — it’s becoming core to acquisition and brand-building for DTC brands.

According to eMarketer, U.S. CTV ad spend will reach ~$33.3 billion in 2025, up roughly 15–16% year-over-year, underscoring advertisers’ rapid shift from linear to streaming.

Here’s why the pivot is accelerating:

  • Customer acquisition costs are rising. Meta and Google CPMs continue to climb while targeting precision erodes. In Q4 2024, Roswell’s portfolio averaged $14–18 CPMs on Facebook, pushing brands to seek more efficient reach.
  • Streaming is now the default. By 2025, roughly 85–90% of U.S. households use at least one CTV device (Statista).
  • CTV is measurable and performance-driven. Impression-level tracking and cross-device attribution make it accountable for real ROI.
  • It builds brand and drives conversion. CTV balances broad reach with precision retargeting — driving both awareness and sales lift.
  • Privacy changes reshaped targeting. With iOS 14.5+ diminishing social audience accuracy, CTV fills a crucial gap for quality reach.

Bottom line: CTV offers the scale of traditional TV with the precision of digital performance marketing — and your competitors are already leveraging it.

How to Think About CTV in Your Media Mix

CTV isn’t just a “new channel” — it’s a strategic amplifier for your entire media mix.

Use it as:

  • An acquisition layer: Reach high-intent audiences that mirror your best buyers.
  • A retargeting amplifier: Re-engage cart abandoners and site visitors through a premium screen.
  • A storytelling upgrade: Share deeper narratives that don’t fit into a six-second social ad.
  • A measurement unlock: Attribute TV exposure to ecommerce conversions via household-level data.
