Retargeting should be one of CTV’s highest-performing use cases. In theory, people who have already visited your website, browsed your products, or purchased from your brand should convert at a higher rate than almost any other.
So why do so many CTV retargeting campaigns struggle to scale and deliver meaningful business results?
The answer has less to do with media inventory or creative than most marketers realize.
It starts with identity.
Identity resolution—the process of identifying website visitors as customers or prospects and mapping them to a household—determines how many people you can reach, how accurately you target them, and ultimately how much revenue your campaign generates.
As CTV evolves into a true performance channel, it’s becoming one of the biggest differentiators between average results and exceptional ones.
Why Identity Resolution Matters in CTV Retargeting
Retargeting always begins with a finite audience. Unlike prospecting campaigns, you can’t simply expand the audience if performance falls short. You’re limited by how many people your technology can accurately identify and activate.
That’s where many CTV strategies break down.
Most CTV providers still rely on digital identifiers like email addresses, device IDs, cookies, or IP addresses to connect consumers across devices. Those signals are constantly changing, incomplete, and becoming less reliable as privacy standards continue to evolve.
Industry experts are questioning whether email-based identity is the right foundation for CTV at all. As AdExchanger recently noted, email addresses don’t map cleanly to a channel built around household viewing, limiting both scale and accuracy.
When identity breaks down, so does performance.
If your technology can only identify a fraction of your website visitors or customers, you’re leaving potential conversions on the table before your campaign even launches.

Why Household-Based Identity Outperforms Digital Identifiers
PebblePost approaches identity differently.
Instead of building audiences around fragile digital signals, Performance CTV starts with the household, using authenticated first-party data to establish a more durable identity foundation.
People replace phones, laptops, and email addresses all the time. They rarely change households. That makes household identity a far more stable basis for audience matching, helping brands consistently reach more of the customers and prospects they actually want to engage.
PebblePost can match 80% of website visitors to a mailable household address, enabling brands to identify and reach eight out of every 10 potential customers. Many CTV platforms struggle to achieve even half that.
The impact becomes clear when you look at the numbers.
Imagine starting with 100,000 website visitors. An 80% match rate gives you roughly twice as many addressable households as a 40% match rate. Combined with stronger conversion performance, that larger audience can translate into hundreds of thousands of dollars in additional revenue from a single campaign.
Better identity also improves targeting accuracy.
Because PebblePost can more confidently distinguish customers from prospects, acquisition campaigns are less likely to waste impressions on people who would have purchased anyway. That means more efficient media spend, more relevant customer experiences, and stronger campaign performance.
PebblePost’s SVP of Product, Amit Nigam, explains why transaction data is critical for CTV measurement.
Transaction Data Drives Better CTV Optimization
Identity resolution determines who you can reach. The data used to optimize your campaigns determines how effectively you can convert them.
Many CTV platforms optimize campaigns strictly using website activity or pixel events. While valuable, those signals only tell part of the story and can be incomplete if pixels fail to fire or consumers move across devices.
PebblePost optimizes campaigns using deterministic first-party transaction data from hundreds of brands. Because transactions represent authenticated customer interactions, they provide one of the strongest and most reliable signals of identity.
That broader, more accurate view of online and offline buying behavior gives marketers greater confidence that they’re reaching the right households and enables campaign optimization based on real purchase activity, not just clicks, page views, or pixel events.
The result is stronger conversion performance over time.
One luxury cruise line recently put that approach to the test. Using PebblePost Performance CTV, the brand generated approximately 300 incremental bookings, more than $1 million in incremental revenue, and 9x iROAS on retargeting campaigns while meeting its rigorous incrementality standards.
What to Look for in a CTV Retargeting Partner
Not every CTV platform approaches identity the same way. Before comparing CPMs or media inventory, marketers should understand how each provider answers a few fundamental questions:
- How is consumer identity resolved?
- What percentage of my audience can be matched?
- Is targeting built on stable, deterministic data?
- Can the platform distinguish customers from prospects?
- Does measurement focus on business outcomes like conversions, incremental revenue, and return on ad spend?
Those answers often have a greater impact on campaign performance than media buying alone.
Identity Resolution Is the Foundation of CTV Performance
As CTV continues to mature as a performance channel, marketers are looking beyond media inventory and creative to understand what actually drives results.
Identity is becoming one of the biggest determinants of CTV retargeting performance.
The ability to reach more of your intended audience, distinguish customers from prospects, and optimize using real purchase behavior influences every metric that follows, from conversions to incremental revenue.
Before asking where your ads will run, ask: How many high-intent consumers can your CTV platform actually identify?
The answer could significantly impact the outcome of your campaign.

Frequently Asked Questions About CTV Retargeting
What is CTV retargeting?
CTV retargeting is the practice of serving Connected TV ads to people who have already interacted with your brand, such as website visitors, existing customers, or app users. Because these audiences have already demonstrated interest, CTV retargeting is often used to improve conversion rates, return on ad spend, and overall campaign performance.
Why is identity resolution important for CTV retargeting?
Identity resolution determines how many people from your target audience you can accurately identify and reach. Higher-quality identity resolution increases audience match rates, improves targeting accuracy, and helps marketers reach more high-intent consumers, making it a critical factor in CTV retargeting performance.
How do I choose a CTV retargeting platform?
When evaluating a CTV retargeting platform, consider how it resolves identity, its audience match rate, whether it uses deterministic first-party data, its ability to distinguish customers from prospects, and whether it measures business outcomes such as conversions, incremental revenue, and return on ad spend.
