Alison Clark, GTM strategy lead for CTV at AdRoll, makes the case that connected TV has crossed from a brand-awareness buy into a measurable performance channel — and that the shift came from three things maturing at once: outcome measurement, audience targeting down to the account and contact level, and the ability to optimize campaigns mid-flight instead of waiting for a post-campaign report. She and Greg Kihlström work through what that means practically: how brands activate first-party data they already hold against CTV audiences, which signals justify a creative refresh versus an audience expansion, how to measure a channel that produces no click, and why unified cross-channel messaging is testable rather than a matter of taste. Clark’s framing throughout is that CTV is not a replacement for other performance channels — it is the thing that makes the rest of the media plan work harder.
Key takeaways
CTV became a performance channel because measurement caught up to it. Advertisers can now trace what a viewer did after the ad aired — branded search, site visit, conversion — so the buy is judged on business outcomes rather than reach.
Targeting on CTV now reaches account and contact level. On the ABM side of AdRoll’s business, audiences can be built down to named accounts and contacts; on the B2C side, purchase history, prior site visits, and demographics drive the segments.
CTV is never a replacement — it is a multiplier on the rest of the plan. Clark’s test is whether adding CTV lifts search volume, click-through rate, and conversions across the other channels, which is what AdRoll sees when clients add it.
First-party data is only an asset once it is organized and usable. Brands already hold loyalty records, site visitors, and abandoned carts; the work is segmenting them so loyalists, new customers, and cart abandoners get different treatment across every channel.
The optimization wait is gone, but constant tinkering is still the wrong move. Results arrive in real time, yet campaigns need time to reveal trends — change on signal, not on impulse.
Falling site visits and conversions read as creative fatigue; flat new traffic reads as an audience-size problem. Those are the two diagnostic signals Clark uses to decide between a creative refresh and an audience expansion.
There is no last click on CTV, so attribution has to be built from influence. AdRoll uses Innovid as third-party validation and layers cross-channel attribution to show where CTV sits in the mix and how it moves accounts along.
Unified messaging works, and you can prove it with a market holdout. Run the unified campaign in a set of markets, withhold it in others, and measure incrementality, site traffic, and conversions against the difference.
Creative must be built per format even when the message is single. CTV needs sight, sound, and motion storytelling; out-of-home needs bold interruption; display needs the click — same brand promise, different execution.

Why CTV stopped being a brand-only line item
The reclassification wasn’t a single product release. Clark points to three capabilities maturing together: measurement that follows a viewer from exposure to branded search to conversion, targeting specific enough to reach named accounts and contacts on the ABM side, and optimization that happens while the campaign is live. Before all three existed, CTV could only be defended as awareness. With them, the same buy is accountable to the same outcomes as any performance channel.
Why “does CTV replace my other performance channels?” is the wrong question
Clark reframes it as a lift question: how does CTV make the rest of the media work harder? The measurable version is whether search volume, click-through rate, and conversions on other channels improve when CTV is in the plan — which is the pattern AdRoll reports seeing across clients. She is direct that CTV is expensive; the justification is the lift it produces elsewhere plus the storytelling it enables that other formats can’t carry.
First-party data is a segmentation problem before it is a targeting problem
Brands are sitting on loyalty data, site visitors, and abandoned carts. Clark’s practical sequence is to organize that data, make it usable, then build segments that reflect genuinely different conversations — a loyalist should not receive the message written for someone who abandoned a cart. Only then is it worth activating across CTV and retargeting. Skipping the organization step produces targeting that looks sophisticated and performs like a broadcast.
The two signals that tell you what to change mid-flight
Real-time reporting creates a temptation to fiddle. Clark’s guardrail is to let campaigns run long enough to show a trend, then read two specific signals. If site visits and conversions are declining, the read is creative fatigue — refresh the message or the call to action. If new traffic isn’t arriving, the audience is too narrow and needs expanding. Budget then shifts toward the creative and audiences that are working.
Attribution when the channel has no click
CTV influences what happens next rather than capturing the last interaction, so Clark builds the picture from two sources: a third-party measurement partner (AdRoll uses Innovid) to validate response timing and creative performance, and cross-channel attribution to show where CTV sits in the overall mix and how it progresses accounts or customers. The requirement she keeps returning to is defining KPIs before the flight, because there is no last click to fall back on afterward.
Proving unified messaging instead of asserting it
Unified messaging makes a brand recognizable and, in Clark’s experience, performs better — but she treats it as testable. Run the unified campaign in a few markets, hold it out of others, and compare incrementality, site traffic, and conversions. That converts a creative principle into a measured result. The nuance is that unification applies to the message, not the execution: each format still gets creative built for its own context.
What a unified stack actually delivers
The end state Clark describes is a single view: first-party audiences activated out of the CRM and CDP, all media measured together, the full customer journey visible in one place, and AI agents running background optimizations faster than a human team could. The payoff is the ability to state plainly which channel combinations drive which business outcomes, and whether the plan is producing incrementality and new customers rather than only retaining existing ones.
FAQ
What changed to make CTV a performance channel rather than a brand channel? Three capabilities matured together: measurement that tracks post-exposure behavior through to conversion, audience targeting granular enough to reach specific accounts and contacts, and real-time optimization during the flight.
Can CTV replace existing performance channels? No. Clark frames CTV as a multiplier — the question is whether adding it lifts search, click-through rate, and conversions across the rest of the media plan, not whether it substitutes for anything.
How should brands use first-party data with CTV? Start by organizing what already exists — loyalty records, site visitors, abandoned carts — into usable segments, then activate those segments across CTV and retargeting so each audience gets a message built for it.
How do you measure CTV when there is no click? Through influence rather than last touch: a third-party measurement partner to validate response and creative performance, plus cross-channel attribution showing how CTV moves accounts and customers along, with KPIs defined before the campaign runs.
What signals should trigger a mid-campaign change? Declining site visits and conversions point to creative fatigue and a refresh; flat new traffic points to an audience that needs expanding. Let the campaign run long enough to show a trend first.
How do you know unified cross-channel messaging is working? Test it. Run the unified campaign in selected markets, withhold it in comparable ones, and measure the difference in incrementality, site traffic, and conversions.
