A blended CPA target assumes every order carries the same profit. It does not—scaling Meta spend into the wrong SKU mix is one of the most common ways brands buy unprofitable growth.

## Why blended CPA fails

A single account-wide CPA target assumes every order has equivalent margin. Once product mix shifts toward lower-margin SKUs, hitting that same CPA target can mean losing money on a growing share of orders.

## Building margin-aware campaign structure

Group SKUs into margin tiers—typically three or four is enough—and set a different CPA or ROAS target per tier rather than one number applied across the entire account.

## Watching for scale-driven mix shift

As Meta spend increases, delivery algorithms often surface whichever SKU converts most easily, not whichever is most profitable—monitor mix continuously rather than assuming it stays stable as spend grows.

## FAQ

**Should every SKU get its own campaign?**

Not necessarily—three or four margin tiers are usually enough to catch the biggest mix-driven margin swings without fragmenting budget across too many campaigns.

**How often should CPA targets be revisited?**

Whenever COGS, fees, or shipping costs change, and at minimum every quarter even if nothing obvious has shifted.

CostRadar segments SKUs into margin tiers automatically, so Meta budgets can be set against contribution margin instead of one blended CPA target.
