Did Your TV Campaign Actually Work? Here’s How to Measure the Real Impact.

Universal Ads campaigns generate roughly 2x higher incremental ROAS than broader CTV benchmarks.

Performance marketers are used to measuring results. But there’s one question that standard attribution can’t answer: Would those conversions have happened anyway?

That’s the question incrementality testing is built to answer. And it’s how advertisers on Universal Ads are going beyond attribution to validate the real impact of their TV campaigns with top-performing campaigns reaching 7%+ lift and ~2x efficiency.

‍

Why incrementality matters for premium TV measurement  

Attribution tells you what happened after someone saw your ad. It’s fast, always on, and essential for optimizing campaigns in flight. But it’s only one part of the picture because it can show correlation but not causation.  

For TV especially, this gap matters. Because there are no clicks and conversions and purchases typically happen on a different device than the one showing the ad, traditional attribution ends up undercounting TV’s contribution. The result has been years of TV being undervalued, not because it wasn’t working, but because the tools available couldn’t prove it was.  

Incrementality testing on the other hand works by setting up a controlled experiment: a group that sees your campaign, and a holdout group that doesn’t. The difference in outcomes between those two groups is the incremental lift your campaign drove.  

Universal Ads runs these studies in partnership with established third-party measurement providers in our Universal Ads Business Partners Program. The primary method is the geo lift study: geographic regions are split into test and holdout groups, outcomes are compared after the campaign window, and the result is a statistically grounded answer to the question: “What would have happened if this campaign had never run?”

‍

Why a geo lift study is a strong fit for TV

Geo lift measures outcomes at the market level, without relying on clicks or deterministic identity. This makes it a practical approach for channels like TV, where exposure and conversion often occur on different devices. Its accuracy depends on a few core conditions:

• Sufficient scale: Enough impression volume and conversion density to detect statistically significant lift. ‍
• Stable baseline: Consistent pre-campaign historical trends to establish a reliable correlation between treatment and control regions. ‍
• Clear isolation: Minimal media spillover or signal cross-contamination between test and holdout markets.

When these conditions are met, geo lift provides a statistically grounded framework for estimating the causal impact of TV investments and quantifying incremental return on ad spend (iROAS)/cost per incremental acquisition.

What the results show

Across Universal Ads’ geo lift study portfolio, we see consistently strong incremental performance—anchored by ~5% lift and ~1.1x iROAS at the median, with top-performing campaigns reaching 7%+ lift and ~2x efficiency, reinforcing the channel’s ability to drive meaningful, scalable growth.¹

Client results also show that nearly half of incremental conversions can come from new customers, highlighting CTV’s ability to expand reach and drive incremental acquisition alongside existing demand.

Independent third-party benchmark analyses show that Universal Ads campaigns can deliver ~2x higher incremental ROAS than broader CTV benchmarks²—highlighting the meaningful impact of high-quality inventory, audience reach, experimentation and execution.

Proof points from the portfolio

Here’s what that looks like in practice, across verticals running on Universal Ads:

Premium Apparel Brand

Achieved 14.9% incremental lift and 1.59 iROAS, providing the confidence needed to expand from regional testing to national investment  

Home & Lifestyle Brand

Produced a 15.2% incremental lift, with 85% of incremental sales coming from new customers, helping justify a transition to national, evergreen CTV investment  

Fitness Equipment Brand

Recorded an 18.9% and 31.2% incremental lift across multiple studies, demonstrating repeatable incremental impact and supporting broader national scale.

‍“When Universal Ads was running, the difference was evident. We have been doing this for two months and are seeing clear results across all channels.” – Adriano Caccamo, Head of Growth, Pathfinder Brands

‍"The test proved Universal Ads to be extremely efficient - driving a 50% lower cost per incremental order." - Melanie Meadows, Growth Marketing Manager, Free Fly Apparel

Attribution and incrementality: Better together

Attribution and incrementality answer different questions. Attribution supports in-flight optimization. Incrementality measures causal impact. Used together, they provide both speed and confidence.

The advertisers seeing the strongest results use both: attribution to make in-flight decisions, and incrementality to build the business case for scaling and using the results to inform their next decision, not to declare victory or failure.  

The goal isn’t one-off experiments. It’s a measurement flywheel that feeds smarter media decisions with every campaign you run.

‍

Your next campaign should answer a question

To maximize your impact, your next campaign should answer a real question: “What would have happened if this campaign had never run?” Incrementality tells you. And once you have that answer, every budget conversation, every scale decision, every channel comparison gets a lot easier.
