Revenue Attribution Is Feeding You False Wins

@Chubbies built a brand on weekend energy and short shorts. The community is real. The revenue attribution? Probably telling the team they are winning while profit flatlines.

The reflexive invariant: "ROAS proves our media is working." That closure solves the revenue polynomial and ignores the profit polynomial. They are different equations with different roots. A channel can drive $2M in attributed revenue and contribute $300K in profit. That 15% margin with 30% acquisition cost is a loss, not a win.

When I took over a $45M budget operation, every channel was optimized for revenue. We tripled spend. Profit flatlined. In 60 days, I rebuilt the attribution model around profit. We cut spend by 23%. Profit grew 47%.

The Profit Attribution Framework:

1. Attribute margin, not revenue. Every channel gets graded on contribution to bottom line. Revenue without margin is just expensive ego.
2. Include customer service costs in CAC. High-return customers destroy profit if you are not tracking it. Return rates vary by channel.
3. Lifetime profit, not first-order value. Channels look unprofitable until month 6 when repeat purchases compound. Measure cohort profit curves.
4. Cohort-based profitability by acquisition date, not calendar month. A January cohort and a June cohort have different profit trajectories.
5. Predictive profit modeling. We forecast profit before spend, not after. If the predicted cohort margin does not clear the threshold, we do not buy.

The inverse influence: reframe every ROAS conversation into a margin conversation. That shift alone changes which campaigns get funded and which get killed.

I have enabled a £790M IPO and cut CPA 66%. The breakthrough came when we stopped optimizing revenue and started engineering profit.

What is your most profitable channel by margin? Is it the same as your highest ROAS channel?
