The margin squeeze
Tariffs Took Your Margin. Ad Waste Takes the Rest.
Tariff churn raises landed costs you cannot negotiate away, and customer acquisition costs are up 40 to 60 percent since 2023, so many first orders are loss-making. The one budget lever a DTC operator fully controls this quarter is wasted ad spend: the share of the budget that never caused a sale. Auditing it takes a causal read of your GA4 export, and cutting it is margin recovered without touching growth.
The squeeze, itemized
Section 122 tariff churn keeps landed costs unstable, and replacement rates are expected higher, not lower. Meanwhile CAC has climbed 40 to 60 percent since 2023 across DTC categories. When both lines move against you, the reflex is to cut ad budgets across the board, which starves the channels that were actually working.
Cut waste, not working spend
Across-the-board cuts treat every euro as equally productive. They are not: platform-attributed revenue includes conversions that would have happened anyway. The causal question, which spend is incremental, is the difference between cutting fat and cutting muscle. Brands that ran the audit found entire line items with no incremental contribution.

FAQ
How do tariffs affect DTC ad budgets?
Tariffs raise landed costs, compressing contribution margin per order. With CAC up 40 to 60 percent since 2023, loss-making first orders force budget scrutiny, and wasted ad spend is the first place to recover margin.
How do I cut ad spend without losing sales?
Cut non-incremental spend, not spend across the board. A causal read identifies which channels drive revenue that would not have happened anyway; everything else is a safe cut.
What is a wasted ad spend audit?
A measurement of how much of your budget produces no incremental revenue. Estimate it with the free calculator, then verify per channel with a causal read on your GA4 export.
How much have customer acquisition costs actually risen?
Benchmark roundups put DTC customer-acquisition costs up roughly 40 to 60 percent from 2023 to 2025, with the average brand now losing money on a first order, which is exactly why cutting non-incremental ad spend beats cutting budget across the board.
What does the audit cost?
€99, one-time, on a GA4 export, refundable if it does not move a budget decision. Pro at €299/mo runs the same model continuously.
