The PMax campaign that bought its own brand name
A Kochi furniture store launched PMax and saw an impressive ROAS within two weeks. The owner wanted to move the whole budget there.
In the channel performance and search term insights, most conversions came from people searching the store’s own name, who would have bought anyway.
We added brand exclusions, ran a separate brand Search campaign at a low budget, and fed PMax better product images and a cleaner feed.
Reported ROAS fell, but new-customer sales rose. The first version had been taking credit, not creating demand.
Illustrative example based on a common pattern in Kerala e-commerce accounts. Numbers rounded.
What Performance Max is
PMax replaces choosing networks yourself. Google mixes placements based on your conversion goal and the signals you give it.
You control inputs, not placements: conversion goals and values, budget and bid strategy, asset groups (headlines, images, videos), audience signals, brand exclusions, negative keywords, and for retail the Merchant Center feed.
PMax results ≈ quality of conversion data × quality of assets and feed × budget

1. E-commerce with a good feed
PMax is the main Shopping campaign type for many stores once purchase tracking with values works.

When the number lies
- Brand cannibalisation
- Reported results may include brand searches you’d have won for free. Use brand exclusions and compare with a brand Search campaign.
- Low-quality leads
- PMax can find cheap form fills on Display. Check lead quality in the CRM by campaign.
- Limited visibility
- Use Channel performance and Search term insights reports to see where results come from.
Mistakes to avoid
Launching PMax without solid tracking
It optimises for the wrong actions and spends fast.
Using only stock images and no video
Weak creative and auto-generated videos that look generic.
Judging it in the first week
PMax needs 2–6 weeks to learn.
