Media plan optimization means tracking revenue times margin minus media spend, channel by channel. This matters because each channel’s profit curve bends, where more spend grows revenue but stops doing it efficiently. Without tracking that inflection point, marketers leave profitable spend on the table or fund a channel past where it pays off. This video explains how to find each channel’s maximum profit point, and why it repeats every week.
Why Media Plan Optimization Comes Down to Finding Each Channel’s Profit Curve
Media plan optimization comes down to finding each channel’s profit curve, because the same dollar that grows profit in one channel can already be past the point of diminishing returns in another. In this video, John Wallace, CEO of LiftLab, starts with the KPI that matters: marketing’s contribution to profit, defined as revenue times profit margin, minus paid media expenses. Plotted out, that number traces an inverted U for most channels, rising as spend increases, then bending as the channel becomes saturated and additional spend keeps growing revenue without growing it efficiently.
The question to ask of every channel is the same: is there room to spend more here, or has this channel become saturated? Wallace notes the answer often isn’t all-or-nothing for a whole channel, but applies to specific portions of the spend within it. The point of maximum profit isn’t usually a single sharp peak either; it’s often a wide, flat region where several nearby spend levels perform almost identically well. And because media costs and audience response shift every week, this isn’t a one-time calculation. A channel’s curve can move left or right as CPCs change or a competitor starts bidding up the same audience, which is why Wallace describes profit optimization as a continuous process rather than a project with an end date.

In this video, LiftLab CEO John Wallace walks through how to optimize a media plan for profit, channel by channel, and why the process never really finishes.
[0:00 – 0:12] Defining the Goal
Sometimes the question I get is, if I were the head of marketing, how would I go about optimizing my media plan for profit? I think it’s a really valid question, one that we can dig into.
[0:12 – 0:38] Marketing Contribution to Profit
First is to define that KPI: what do I mean by profit? In finance, the term that we’re talking about is marketing’s contribution to profit, and it’s defined as your revenue times your profit margin minus your expenses for paid media. That’s going to give you a metric that’s a function of revenue, your profit margin, and then how much you’re spending. As you spend more and more on marketing, we all feel that phenomena of saturation; that’s what we’re trying to capture with this.
[0:38 – 1:20] Identifying Saturation and Diminishing Returns
It turns out that profit can be plotted, and quite often these profit curves have an inflection point. They’re kind of an upside down U. What that means is there could be, in order to optimize for profit, channels where we’re over here on this curve, and by spending more, we can continue to increase the profit. There could be other channels, and this is the definition graphically of saturation, where some of the more recent levels of spend, while they do increase the revenue, they’re not doing it efficiently. We’ve become inefficient, or we’ve become saturated, or some say past the point of diminishing returns. In those conditions, we can actually increase our profit by spending less.
[1:20 – 1:59] Channel-Level Optimization
The question becomes for each and every one of our channels: what condition are we under? Are we leaving money on the table, or are we saturated? There are areas of the spend, not the whole channel, we’re not going to punish the whole channel, are there portions of this spend that need to be corrected, or do we need to bring it back? Doing this for every one of your channels does set you up to optimize for profit. I’ll say that this point that’s highlighted in purple, I like to refer to this as the textbook maximum profit, because if you look at this graph, there’s several points here, all this whole region where, while the profits are not identical, they’re very, very close to one another.
[1:59 – 2:17] Understanding Trade-offs
So the whole point of LiftLab is to help marketers understand these trade-offs. Would I be willing to give up a little bit of profit here in order to get the extra revenue? That’s not a decision that LiftLab can make; it’s one that we can present the information to marketers and let them take advantage of it when they’re making their weekly optimizations.
[2:17 – 3:10] The Continuous Process of Optimization
Then what we’ve also seen customers experience is, hey, now that I’ve optimized for this profit, am I done? The answer to that is no. The changes each week in the price of media, namely in CPCs and CPMs, will shift these curves around. Maybe my maximum profit moves to the right, or maybe it moves to the left a little bit, as well as changes in response rate. If you’ve had a bunch of the audience that you were privy to get bought up in the auction by a competitor, that could decrease the quality of that media and then shift that profit curve over to the left. So it’s an ongoing opportunity to optimize; you’re never done optimizing. But it is really heartwarming to watch new brands to LiftLab identify these areas to double or triple their spend, or, of course, in the case where they need to cut their spend back in order to increase their profit.
Key Lessons: Optimizing Your Media Plan for Profit Every Week
Financial strategy: Marketing’s contribution is identified by subtracting paid media expenses from the product of revenue and profit margins.
Performance analysis: Marketing spend reaches an inflection point where additional investment yields decreasing efficiency, signaling a need for budget reallocation.
Optimization workflow: Weekly shifts in costs and audience behavior mean that media plans must be regularly adjusted to maintain maximum profitability.
