Northbeam just dropped their April 2026 numbers and the headline is ugly: median CAC is up 9.7% year over year. Ad spend tracked nearly identically, up 9.6%. So brands are spending more and getting exactly the same volume of customers for it. On paper, efficiency held. In practice, you went backwards.
Before I go on, I’d hugely recommend the Northbeam newsletter, The Media Buyer, to help you keep an eye on consolidated data across industries and market trends... and no, this isn’t a paid promo.
Brand Size and AOV: What the Northbeam Data Reveals About Rising CAC
The Northbeam breakdown gets more interesting when you cut it by revenue band;
Brands under $5m annual revenue saw CAC spike 9.6% on a spend increase of 14.2%.
They burned more fuel and went slower. Meanwhile, brands doing $100m+ essentially broke even on CAC.
Don’t go away thinking that the $100m brands are running smarter ads (they rarely are). They’re converting more efficiently because consumers already know them. Their consideration cycle is shorter. Their trust floor is higher. When CPMs rise and auction costs compound, brand equity acts as a buffer. Smaller brands have no buffer. Every ad impression has to work harder because their brand isn’t doing any of the work on its own.
The same dynamic shows up when you cut the data by AOV. Low AOV products took a beating. High AOV products, already fighting longer consideration cycles, saw CAC deteriorate significantly as retargeting costs increased. The math compounds against you the higher your price point.
This tells me two things immediately.
1.) Rising CAC in this environment is a structural problem, not a channel problem. Meta’s algorithmic changes in March, which now favour campaigns with 50-plus weekly conversions and reward creative refresh cadence over targeting precision, accelerated an existing dynamic. The brands with consistent creative volume and enough conversion data to feed the algorithm maintained performance. Everyone else scrambled.
2.) The brands that are losing this game have been underinvesting in the thing that makes paid media cheaper over time: brand.
The Misdiagnosis: Treating Rising CAC as a Media Problem Instead of a Conversion Problem
So, when CAC rises, the instinct is to optimise the channel. Do more work. Pull back on underperforming ad sets. Improve hook rates. Refresh creative. These are all legitimate levers and you should be pulling them. But they’re all working on the symptom.
The real question you, and collectively ‘we’ as an industry need to be asking is why conversion is expensive in the first place.
If a consumer lands on your site and doesn’t convert, you have to chase them with retargeting spend. The more that happens, the higher your effective CAC. Now multiply that across a category where consumers are under financial pressure, prices for everyday goods are up, and lower-income spenders are actively pulling back. The leaky bucket is now costing you retargeting budget that’s compounding month on month.
The brands that held CAC flat in April probably have more prospects between the awareness and purchase phase. It’s that simple.
First Steps to Diagnose Rising CAC: Landing Pages, First-Order Economics, and Traffic Intent
If I were sitting across from a founder with rising CAC right now, the first thing I’d do is ignore the media account for ten minutes and do the following;
1.) I’d pull the ad landing page. I’d look at what a first-time visitor actually sees when they land. Is the product explained in a way that collapses the consideration cycle? Is the offer clear? Is the social proof in the right place? Does the page earn trust before it asks for a transaction?
2.) Then I’d look at the first purchase economics. What does the contribution margin look like on the initial order? Is the CAC defensible against that margin, or does the unit economics only make sense if a customer repurchases? If you need repeat purchases to justify CAC, and your retention rate isn’t supporting that, then you’re renting rather than acquiring customers.
3.) Then I’d look at traffic intent. Not all traffic is equal and your attribution model is probably not telling you the full story. Northbeam’s data reflects a macro trend but your specific situation depends on whether the traffic you’re buying is actually in-market or whether you’re funding a very expensive discovery channel that converts cold.
Tools like Lifetimely are useful here for modelling the payback period honestly, and Littledata helps you verify that the conversion data feeding your ad platform is actually accurate. Bad data in means bad optimisation out. That matters more when margins are compressed.
Fix Conversion and Build Demand-Creating Channels
The brands that are going to come out of this period in better shape are the ones who know the levers that help them to reduce how much paid media they need to grow.
That means two things in practice.
1.) fix the conversion system so that fewer acquired visitors require retargeting. Every percentage point of improvement in first-visit conversion reduces your effective CAC without touching your media plan.
2.) invest in channels and assets that create demand without being tied to auction-based pricing. Organic content (SEO is a whole other story we’ll leave to another day), affiliate and partnership channels, email, and community all operate outside the Meta auction. They lower your average cost per acquisition, your Blended ROAS, because they exist in parallel to your paid activity rather than competing for the same consumer at an increasingly expensive price.
The data shows that small brands are spending more and getting less. This doesn’t mean that your response spend less and get even less. You need to build the infrastructure that makes the spend you do deploy work harder.
How Reframing CAC as a Conversion and Retention Problem Changes Your Growth Plan
When you stop treating CAC as a media problem and start treating it as a conversion and retention problem, your whole planning model changes.
You stop chasing efficiency within channels that are structurally getting more expensive. You start looking at payback period as the real metric. If you can improve first-order contribution margin and increase the percentage of customers who repurchase within 90 days, your allowable CAC goes up. Its painful, and nowhere near the conversation you would have been having just 3-4 years ago. It is the reality and as your economics improve you can afford to compete harder.
That’s the compound advantage the $100m brands have. Their LTV is higher, their brand awareness lowers consideration cost, and they can outbid you in an auction and still make the unit economics work. You can’t beat them at that game. You can, however, build towards a position where you don’t need to.
The Key Question: How Does Your Business Withstand Another Rise in Meta CAC?
The Northbeam data captures a moment in time. April 2026 was a hard month for smaller DTC advertisers and a tolerable one for the big players. That gap isn’t closing on its own.
So the real question for any DTC founder reading this isn’t “how do I get my CAC back down?” It’s if Meta’s algorithm becomes 20% more expensive again next quarter, what part of your business absorbs that without breaking?
If you can’t answer that clearly, the problem is your architecture and not your creative.
