Google Ads efficiency myths die in a contribution margin report. Separating brand, non-brand, and Shopping economics is necessary before anyone celebrates an account-wide ROAS number.

## Where the myths live

Brand search looks efficient largely because it captures demand that would often have converted anyway. Shopping campaigns can scale spend into whichever low-margin SKU the algorithm favors, inflating volume without inflating profit.

## Separating the three economics

Brand search (efficient, but only partly incremental), non-brand search (real acquisition cost), and Shopping (mix-dependent, needing SKU-level margin data to judge fairly)—each deserves its own profitability lens rather than one blended account view.

## A profit-first operating model

Feed accurate per-SKU margin data into Shopping campaigns wherever margin-based bidding is available, and periodically audit brand search spend against real incrementality rather than assuming it is always worth funding.

## FAQ

**Is brand search spend ever wasted?**

It can cannibalize free organic clicks, especially when a brand already ranks first organically—test pausing it periodically to check.

**Does Performance Max change this?**

No—Performance Max still needs accurate margin signals fed into it, or it will optimize toward whatever converts, not whatever is profitable.
