The Problem

Performance Max will spend whatever you give it.

“The question isn’t whether PMax is spending. It’s whether it’s finding sales you wouldn’t have made anyway.”

PMax reports a higher ROAS than everything else, and nobody can explain why

Bestsellers soak up the budget while the rest of the catalogue never gets seen

Low-margin products sell well but barely make money

Out-of-stock and discontinued products keep spending

You can’t see where Performance Max spend actually goes

What’s included

What’s included in Shopping and Performance Max management

Custom label strategy

Products grouped in the feed by margin, performance, stock, price point and seasonality.

Commercial campaign structure

Shopping and PMax campaigns split via custom labels and traffic type, each with its own target and budget.

Brand protection

Brand exclusions and a dedicated brand Shopping campaign, so PMax isn’t credited for customers already searching for you.

New customer focus

Customer acquisition settings and value rules where a new customer is worth more than a repeat order.

Channel visibility

Regular reviews of where spend goes across Shopping, Search, Display and YouTube placements.

Incrementality testing

Holdout and geo tests where spend is large enough to show whether PMax adds incremental sales or only claims them.

How we work

How we work

How we build it

What working with us looks like, from the first review to ongoing growth.

Step 1

Feed and data review

We check Merchant Center health, product data and margins before touching campaign structure.

Clean foundations

Step 2

Label and segment

We add custom labels so products are grouped by what they’re commercially worth.

Commercial segments

Step 3

Launch and separate

PMax runs on proven products, Standard Shopping handles testing and costly queries, and brand sits apart.

Clear campaign roles

Step 4

Test and scale

We move budget between segments as data builds, and test incrementality where spend allows.

Measured growth

Shopping vs Performance Max

Standard Shopping still has a place. It gives product-level search term control that PMax doesn’t. We often run both: PMax for scale on proven products, Standard Shopping for testing, controlling costly queries, or catalogue segments PMax overspends on.

Built on a clean feed

Campaign structure only works with accurate product data. Most accounts start with a Merchant Center and feed review to fix disapprovals, titles and missing attributes first.
