Audit PMaxStan Consulting · do it yourself guides
These guides are written for Shopify owners and operators who spend money on Google and Meta and want to know whether the claimed numbers reflect real revenue growth. Open them and you will be able to tell the difference between a PMax campaign producing demand and one farming existing demand, and see the structural problems inside a Shopify feed, tracking setup, and campaign architecture that cost most stores a quarter of their ad budget.
Quick answer
This pillar covers how to audit Shopify paid media without agency access: Performance Max architecture, the Shopify-to-Merchant Center feed, conversion tracking through the Shopify-Google app, brand search contamination of ROAS figures, and the new customer acquisition rate that separates real growth from retargeting revenue. It is written for store owners and operators who assess their own numbers. If you need the framework applied to your specific store rather than the framework itself, the Conversion Audit delivers written findings in 72 hours for scoped after intake.

Why this guide matters: Shopify traffic, carts, or paid traffic are not becoming purchases. Traffic and ad spend continue while PDP, offer, cart, checkout, or attribution leaks stay active. Use the guide to check the pattern before adding more paid traffic.

A guide describes the pattern. Your store has a specific version of that pattern, and the specific version is where the marketing audit sits. In a typical Shopify account running PMax, the patterns interact: one asset group covering 400 SKUs, a feed where 18 percent of products are disapproved without anyone noticing, the Shopify-Google app firing Purchase and Add to Cart as separate conversion actions with equal weight, a brand search campaign absent so PMax is absorbing branded queries and tracking a 9x ROAS that does not exist, and a retargeting audience that is 60 percent of spend because the algorithm found it easier than acquiring new customers. Any one of these on its own has a clean answer. Together, they require ordering.
If that describes your situation, the next step is the Conversion Audit. Written findings, prioritized fix list, 72-hour turnaround, scoped after intake, no retainer. The marketing audit checks your actual store: Shopify data, Merchant Center, the PMax asset groups, the conversion events in Google Ads, and the feed attributes Shopify exports. You get the specific list, in the order that matters for your store, not the general framework.

Buyer friction. Most weak marketing paths fail because the buyer lacks proof, context, urgency, or a clear next step.
