My job is to fix things. It’s what I’ve been doing in Ecommerce for over 25 years. When I say ‘things’ I mean growing the gap between money out and money in (in a good way). And weekly calls right now are constantly focused on the challenge of scaling with diminishing results. So, let’s chat through one opportunity to shift the focus away from current channel performance … beyond just ads.
Meta and Google are there spouting out their AI ‘recommendations’ to push your budget up… and you follow their guidance and lo and behold, your ROAS drops. You push it up again this time adding new content. New videos in all the formats suggested. ROAS drops further. You tell yourself the algorithm needs time to learn. And you increase the budget again.
Is this really an ecommerce growth strategy or a slow bleed dressed up as optimism?
The law of diminishing returns is a wall every DTC brand hits at some point on its paid acquisition journey. Brands that push to next-stage growth are usually those that look beyond the channel they were already in. They’re looking (and working) beyond just ads.
Why Rising CAC Isn’t Just a Media Buying Problem
You’ll notice CAC climbing and your target ROAS will feel harder to hold. Those campaigns that worked twelve months ago? They’re now underperforming despite identical structures. Your natural instinct is to assume the issue is tactical: wrong bidding strategy, wrong creative, wrong audience segmentation.
So you optimise.
- You test new creatives.
- You restructure campaigns.
- You bring in a new agency (again!).
Sometimes these moves buy a few weeks of improvement. Then the ceiling returns.
The misdiagnosis here is treating a structural problem as a channel problem. Most founders assume their paid media is underperforming because something inside the channel is broken. In reality, the channel is often doing exactly what it can do at the current scale.
You have simply reached the point where every additional pound of spend is chasing a smaller and smaller pool of genuinely convertible demand.
As you head up the funnel you’ll see conversation rates decline. These people simply aren’t in market like those lower down the funnel… when Meta looked far healthier.
What Actually Happens When Paid Channels Hit Diminishing Returns?
Paid acquisition channels are not infinitely elastic. Meta, Google and TikTok are all bidding environments. You are competing for attention from a finite audience. At the early stages of scaling, you are reaching the people most likely to convert. They are in-market, they have some prior exposure to your category, the algorithm finds them efficiently.
As you push spend higher, the algorithm has to work harder to find the next buyer. They are colder. Less informed. Less ready. The conversion rate dips. The CAC climbs. The payback period stretches.
Are you suffering a creative problem? Is it a landing page problem? A reach problem? You are trying to extract more from an audience you are already saturating, and the economics of doing so get worse with every increment.
The brands that diagnose this correctly are now asking “where are my customers that this channel cannot reach?” rather than “how do I get more from this channel?” That simple reframe changes everything.
The Real Unlock: Moving from Rented Paid Channels to Collaborative Commerce
When diminishing returns hit, the instinct is to diversify into another paid channel. You are on Meta, so you try TikTok. You are on Google Shopping, so you test Display and Demand Gen. You are adding new rooms to the same house.
This is not the unlock.
The unlock is moving from rented audiences to owned and partnered distribution. The most underutilised form of that distribution for DTC brands right now is Collaborative Commerce.
This is the model where your brand stops relying solely on platforms to find buyers and instead builds a network of external partners who already have your customers’ attention. Creators. Niche publishers. Complementary brands. Communities. Content affiliates who write, recommend, and distribute independently of any single ad platform.
The difference in economics is significant. Instead of paying to interrupt someone who may or may not be interested, you are reaching audiences that are already primed, already trusting the voice recommending you, already in the right mindset. The conversion dynamic changes completely.
The Collaborative Commerce Engine: 4 Core Stages to Build Your Partner Network
The Collaborative Commerce model works across four stages: partner identification, value exchange design, activation systems, and performance optimisation.
1.) Partner identification means finding the people, brands, and communities that already have your ideal customers’ attention. These are not generic influencers. They are the niche review sites, the trusted bloggers, the newsletter writers, the YouTube creators who own specific authority in your category.
2.) Value exchange design means building a partnership proposition that is genuinely compelling, not just a commission arrangement. Partners who feel like an afterthought perform like one.
3.) Activation systems mean building the infrastructure to make collaboration consistent: content briefs, campaign toolkits, clear communication, and an easy onboarding path that makes it simple for a partner to publish and promote.
4.) Performance and optimisation means measuring what matters and improving it over time, just like any other growth channel.
The commercial impact compounds in a way paid channels cannot match. CAC becomes more consistent. Trust transfers from the partner to the brand. Growth diversifies across a network rather than depending on a single lever. The relationships you build become a defensible advantage that competitors cannot simply replicate by outspending you.
Why Collaborative Commerce Delivers a Different Quality of Growth Than Paid Ads
What are founders missing when they think about partnership and affiliate channels? They are measuring them on the wrong terms.
If you evaluate a content affiliate by last-click attribution, it looks like it contributes almost nothing. The content partner introduced your brand to someone on Tuesday. That person converted through a direct visit on Friday. Your attribution model gives the credit to the last touch and writes off the content partnership as low value.
This is how DTC brands systematically defund the channels doing the most important work. Are content affiliates, niche publishers, and community-based partners really there to close your sales? No, they are opening buying journeys. The economics look completely different when you measure them correctly.
Tools like Lifetimely help you understand the downstream LTV of customers acquired through different partner sources. What you often find is that partnership-sourced customers have higher average order values, better repeat rates, and lower long-term CAC than customers acquired through cold paid channels. The quality of the acquisition is fundamentally different, and the trust transfer is real rather than manufactured.
The Compounding Advantage of Partner Content vs. One‑Off Paid Ad Spend
There is a second layer to this that matters enormously right now.
Paid media traffic is a tap. You turn it on, customers flow. You turn it off, they stop. Every pound of spend is a discrete transaction. Nothing you build today makes tomorrow’s acquisition cheaper.
How to Audit and Rebuild Your Affiliate Mix Around Collaborative Commerce
Every piece of content a partner creates stays in market. It keeps ranking. It keeps referring. The review a niche blogger wrote about your product eighteen months ago is still driving qualified traffic today. The comparison post a content affiliate published last year is still appearing when someone searches your category. The YouTube video a creator produced about your product is still generating views, still sending warm traffic, still building brand association.
The effort compounds in a way paid media investment never can. In an environment where AI Overviews and LLM-generated answers are increasingly shaping how buyers discover products, that content footprint becomes something more significant still. The brands with the deepest, most distributed independent content presence are the ones AI models learn from and surface when someone asks which brand to trust in a category.
Don’t think of this as a future problem. It is now problem. The brands I’m helping build Collaborative Commerce networks for today are building the compounding infrastructure that will make their growth dramatically more defensible in three years.
What a Well‑Built Collaborative Commerce Program Enables for Your Growth
The starting point is a clear-eyed partner audit. Separate your content partners from your transaction facilitators. Content affiliates, bloggers, publishers, YouTubers, niche community builders all contribute to awareness, search authority, and brand education. Transaction facilitators, cashback sites, voucher platforms, contribute to margin erosion and last-click noise.
If your current affiliate mix is weighted heavily toward transaction facilitators, you are running a discount channel, not a growth channel.
Identify the content gaps next. Where in the buyer’s research journey is your brand not present? Which comparison queries, problem-based searches, and category terms have no independent coverage of your products? Those gaps represent both an SEO opportunity and a Collaborative Commerce opportunity simultaneously. Filling them builds organic authority and AI visibility at the same time.
Then recruit against those gaps deliberately. Find the creators and publishers who already own authority in your category. Build relationships rather than just commission arrangements. The economics follow the content.
Once partners are producing, update how you attribute their contribution. A content partner who introduces your brand to a customer who converts two weeks later through direct deserves recognition in your model. If they are invisible in your attribution, you will systematically defund them in favour of the cashback site that appeared thirty seconds before checkout.
When you build Collaborative Commerce properly, the growth machine stabilises in ways that paid-only scaling never delivers.
CAC becomes more consistent. You are no longer entirely exposed to platform auction volatility. First-order ROAS pressure eases as partnership-sourced customers typically arrive with more purchase intent and better retention behaviour.
Payback periods compress as the cost of acquiring customers through established partner relationships is fundamentally lower than cold prospecting through paid channels.
Most importantly, you create growth that continues working when you stop spending. The content network your partners built is still ranking, still referring, still training AI models to associate your brand with the problems your product solves. No single paid channel offers that.
Stop Renting Growth: Build Owned and Partner‑Led Acquisition Beyond Paid Ads
The law of diminishing returns will always find you if you are scaling a single channel without building anything else.
I’m not telling you to question your spend, keep investing in paid media. What are you building that sits alongside it that compounds, that belongs to you, that keeps working independently of what you spend next month.
If you removed your paid media budget tomorrow, would your growth hold up? Would there be enough independent distribution, enough content presence, enough partnership infrastructure to sustain customer acquisition at a meaningful rate?
For most DTC brands, the honest answer is no.
The founders changing that answer are building networks of trusted partners who already have their customers’ attention, creating a distributed growth engine that earns its returns rather than renting them.
That is the unlock. And it is available to any brand willing to look beyond the next campaign.
