Low-signal marketing data means a model’s revenue estimate rests on weak inputs, not a failing channel. This matters because a flagged channel might be worth funding; the color warns about data quality, not performance. Without an experiment to replace weak signal, marketers guess at a wide ROAS range instead of the number. This video shows a channel move from red to green after an experiment revealed its true marginal ROAS.
Why Low-Signal Marketing Data Doesn’t Mean a Channel Is Underperforming
Low-signal marketing data doesn’t mean a channel is underperforming, because the red flag on a dashboard is a warning about the quality of the data feeding the model, not a verdict on the channel itself. In this video, John Wallace, CEO of LiftLab, walks through LiftLab’s ROI dashboard live, starting with the basic optimization logic: pull spend back from low-ROAS channels, push more into high-ROAS ones, and even though each channel’s own ROAS naturally comes down as spend increases, the average across the whole plan should rise.
Wallace then shows a channel color-coded red for low signal: $25,000 in spend, with the model estimating $140,000 in incremental revenue, but flagged because the underlying data wasn’t strong enough to trust that number precisely. Rather than treating red as a reason to pull spend, LiftLab’s answer is to run an experiment directly from within the platform to generate a stronger signal. After that experiment runs, the same channel turns green, confirming the $25,000 in spend actually drove $139,000, with a marginal ROAS of roughly 3, meaning the next dollar spent there should return about three more.

[0:00 – 0:20] Introduction to LiftLab ROI Dashboards
Hey, we’re inside LiftLab. There’s a number of sections to LiftLab. We’re going to be inside the analyze section, and specifically all of the tabs within analyze, focusing here on the ROI dashboard. People use ROI dashboards so that they can see their performance in an objective way, to quantify their performance and use that performance to optimize.
[0:20 – 0:51] Optimizing Marketing Spend
Specifically speaking, when we say optimize, we’re going to look for low ROAS channels, where that’s an indication that we’ve overspent, and we’re going to look for high ROAS channels and we’re going to increase our spend. Most marketers know the way the law of gravity works: as you increase your spend, your ROAS is going to come down. But by going through that optimization process, what should happen overall is that our average ROAS will go up. We’re going to continue to spend where the ROAS is higher, we’re going to spend less where the ROAS is lower, and our average, our mean, will go higher.
[0:52 – 1:27] Understanding Low Signal Data
You’ll see the color coding over to the side here, and what this is saying is that some of these channels have low signal data. There’s nothing wrong with the channel; it doesn’t mean that you shouldn’t spend there. It’s just that the signal that was presented to our model was low quality. That means that this particular ROAS, we spent $25,000 on this acquisition, the model thinks it has an incremental revenue of $140,000, but this red is indicating that it wasn’t the greatest data going in to make this decision. So that means that maybe the ROAS is below five, maybe the ROAS is higher than five; that’s typically a point of contention.
[1:27 – 1:52] The Role of Experiments
You know what we would do about this? Our playbook is to say, let’s go run an experiment. This isn’t something that we’re just saying in passing; we literally have the section of LiftLab to go design, kick off, and manage that experiment. We use experiment as a synonym for, let’s go get better data. So if we’re not happy with this data, or if we have concerns about this data, let’s replace it with a stronger signal.
[1:53 – 2:31] Improving Decision Confidence
Fast forwarding and seeing the effect of an experiment that’s run, this will change from red to green. What we’ll know now is that the $25,000 that we spent really did drive $139,000. We’ll also know the marginal ROAS; that is, if we were to spend another dollar, it’s going to continue to drive $3 for us. What we’ve shown here is there’s a reality of the data sets that are going in to mix models, and in some cases you’re going to have an appetite and a need for better data. It’s important to us that there’s a method to do that, that there’s software to support it, and that you come out the other end with more confidence in the spend decisions and the optimizations that you’re making.
Key Lessons: Turning Low-Signal Marketing Data Into Confident Decisions
Optimization logic: Marketers should consistently reallocate budget by reducing spend on low ROAS channels while scaling up high-performing ones to improve the mean average.
Data quality assessment: A low-signal status serves as a diagnostic tool, signaling that current data may be insufficient to draw definitive conclusions about a channel’s true revenue contribution.
Experimental framework: Running controlled experiments acts as the primary solution for gathering superior data, turning ambiguous inputs into actionable, high-confidence results.
Strategic confidence: Investing in both robust data methodologies and supporting technology is essential to ensure that budget decisions are backed by reliable evidence.
