Ecommerce economics and scaling
Why one ROAS target can mislead a store with mixed product margins
Campaign averages can hide the difference between profitable product demand and revenue that leaves little after fulfillment.
A single storewide ROAS target can be convenient, but a mixed catalog rarely has one set of economics. Different products can carry different margins, shipping costs, return patterns, and replenishment constraints. The advertising decision should reflect those differences.
Separate revenue volume from contribution
A high-priced item may generate impressive attributed revenue while leaving little after supplier and delivery costs. A lower-priced accessory can contribute more consistently, particularly when it travels in an existing shipment. Revenue alone does not resolve that comparison.
Build a practical product grouping rather than demanding a perfect profitability model on day one. Categories with similar gross margins, delivery characteristics, and return exposure can provide a useful starting point. Flag exceptions that would make a group average misleading.
Match the campaign structure to meaningful differences
Campaign and product-group structure should make important tradeoffs visible. If products with very different economics are evaluated only as one total, strong sellers can subsidize weak ones without the team noticing quickly enough.
That does not mean creating a separate campaign for every SKU. Too much fragmentation can make reporting and testing harder to interpret. Group products when the grouping supports a real decision: different bids, different investment priorities, different creative, or a deliberate exclusion.
Consider the basket without assuming its value
Some products attract orders containing complementary items. Others sell alone and consume most of a shipment’s cost. Review actual basket behavior before assigning strategic value to a low-margin product.
The same caution applies to repeat buying. A product may introduce valuable customers, but the claim needs cohort evidence. It should not become a permanent explanation for poor acquisition performance that nobody has tested.
Revisit the grouping when the business changes
Supplier increases, promotional pricing, shipping changes, and returns can alter the economics faster than an advertising dashboard suggests. Give the campaign team a way to receive those updates. A product should not retain the same spending priority simply because it was a good opportunity last quarter.
At EP4P, product economics matter because we put our own advertising money behind the work. The shared task is to identify sales worth pursuing and a level of investment both sides can sustain. A useful ROAS target is the output of that discussion, not a substitute for it.
