TheSKUThatSellsEverythingExceptItself

Every catalogue has one. A product that generates enormous click volume, looks brilliant in the Shopping report, and barely appears in actual order data.

It's a gateway SKU. And it's distorting your entire budget allocation.

Gateway SKUs tend to share characteristics: lower price point, broad appeal, strong imagery, and a title that matches high-volume search queries. They attract clicks because they look like the answer to the search. But shoppers land, browse, and buy something else.

In Google's reporting, this SKU looks like a top performer. It has conversions attributed to it. It has strong ROAS. The algorithm sees signal and pushes more budget toward it.

But the conversion was for a different product. Often a higher-margin one.

The problem isn't that gateway SKUs exist. Every good catalogue has entry points. The problem is when you treat them as profit centres instead of traffic drivers.

The fix requires reconciliation: match clicked product IDs against actual order-line items. When you do, you'll find the products generating real margin are often buried mid-catalogue, receiving minimal impression share because the gateway SKU is eating the budget.

We assign every SKU a role: Scale, Profit, Recovery, or Gateway. Gateways get capped spend and are measured on assisted value, not direct attribution. The margin improves within weeks.
