PMax without
the black box.

Performance Max managed properly.

What We Do

PMax campaigns
with controls.

Automation needs strategy, not blind trust

Account & Feed Setup

Product feed review, conversion tracking, asset groups, audience signals and campaign architecture built around the way your catalogue actually sells.

Review setup

Brand & Query Control

Brand exclusions, search term insight, negative placements where possible and structure that separates genuine growth from traffic you would have won anyway.

Check incrementality

Creative & Asset Testing

Asset groups, images, copy and product segmentation reviewed continuously so PMax has enough quality input to make useful automated decisions.

Improve assets

PMax needs
better inputs.

Core inputs we tighten first: feed, creative assets and conversion data.

90 days

A practical window for judging whether PMax is creating incremental growth.

0

Blind reliance on automation without checking brand, feed and query behaviour.

100 %

Reporting grounded in revenue quality, not just platform-reported conversions.

Automation works best
when the inputs are clean.

Whatever we throw at them, at Prosper they always deliver. On time, on budget and above expectations every time.

PMax still needs
management

Performance Max is not a replacement for strategy. The campaign learns from the data, feed, assets and constraints you give it. Prosper makes sure those inputs are strong enough for automation to help rather than hide wasted spend.

FAQ

Performance Max questions

How to use PMax without losing control.

What is Performance Max?

Performance Max is Google's automated campaign type that can serve across Search, Shopping, Display, YouTube, Gmail and Discover from one campaign.

Is PMax better than Shopping?

Not automatically. PMax can scale, but Standard Shopping can provide more control. The right setup depends on catalogue size, data quality, budget and how much visibility the account needs.

Why do PMax campaigns waste spend?

Weak feeds, poor creative assets, messy conversion tracking, brand traffic being counted as growth and a lack of structure can all make PMax look better than it is.

Can PMax work for Shopify stores?

Yes, especially when Shopify product data, Merchant Center and conversion tracking are clean. The campaign is only as strong as those inputs.

Do you audit existing PMax campaigns?

Yes. We review feed quality, asset groups, conversion tracking, search/category behaviour, brand reliance and whether the campaign is actually incremental.
