0413 107 893Shopify makes it relatively easy to launch an online store. What it doesn't make easy is getting Google Ads to perform well. The platform has its own Google channel integration, but simply connecting it and letting Google run Shopping campaigns on autopilot is a reliable way to waste money. We've seen it repeatedly: Shopify stores spending real budgets across Shopping and Performance Max with no real data coming back, no visibility into which products are actually driving revenue, and ROAS that looks fine until you look closely and realise the tracking was set up wrong from the start.
Getting Shopify Google Ads right requires three things working together: conversion tracking that records actual purchases with revenue values, a clean product feed that Google can work with, and campaigns structured around how buyers actually search for your products.
Conversion Tracking on Shopify: Getting It Right
Shopify's native Google integration handles basic conversion tracking, but it has limitations — particularly around how conversion values are passed to Google Ads, how it handles dynamic remarketing, and how it interacts with Google Tag Manager if you're running custom tracking alongside it. We've worked with Shopify stores where the revenue tracking looked fine on the surface but was actually double-counting transactions, or where values weren't being passed at all, meaning Google's Smart Bidding had no real signal to optimise against.
We've written a detailed guide on how to set up Google Ads conversion tracking on Shopify that covers the common setups and the issues to watch for. In practice, the first thing we do with any Shopify client is verify that purchases are recording correctly with revenue values, and that the data flowing into Google Ads matches what's showing up in Shopify's own order data.
The Product Feed: Where Shopify Stores Often Leave Money on the Table
Google Shopping and Performance Max rely on your product feed to determine when and where your products appear. The feed pulls from your Shopify catalogue, but the default export often produces titles and descriptions that are too generic or too technical to match the actual search queries buyers use.
A product listed in your Shopify store as "HYG-PRO-500ML-BLUE" might be a bestselling hand sanitiser, but that product title won't trigger relevant Shopping impressions. Shoppers search for "hand sanitiser bulk" or "alcohol hand sanitiser 500ml Australia" — and if your feed titles don't reflect that language, your products either don't show up or show up in the wrong contexts.
Feed optimisation — rewriting titles to match search intent, improving descriptions, ensuring images meet Google's quality requirements, and fixing policy issues that suppress product eligibility — is one of the highest-ROI activities in a Shopify Google Ads account. It costs nothing in ad spend and directly improves both impression share and click quality.
A 7.67x ROAS in Month One
In early 2026, we took over an Australian e-commerce account in the hygiene products space. The previous setup had no conversion tracking, which meant their Performance Max campaign had no data to work from and was effectively running on guesswork. The other campaigns — Standard Shopping and Search — were similarly unoptimised.
We started by implementing full purchase tracking with conversion values. Once that was confirmed working, we rebuilt the PMax campaign around a curated product selection rather than the full catalogue, excluded demographic segments that weren't converting, built a comprehensive negative keyword list, set up ad scheduling based on when conversions were actually happening, and optimised the product feed.
The results after the first full month: A$9,632.73 in tracked revenue from A$1,452.24 in spend — a 6.63x account-wide ROAS. The PMax campaign alone achieved a 7.67x ROAS. Both primary campaigns ended the month budget-limited rather than performance-limited, meaning there was a clear path to scale. Full details are in our Google Shopping PMax case study.

Building Audiences from Your Shopify Customer Data
One advantage Shopify stores have that many don't make use of is existing customer data. If you have a list of past purchasers, that data can be uploaded to Google Ads through Customer Match and used to build lookalike audiences, bid more aggressively to known customers, or exclude past buyers from acquisition campaigns. We've written about how Customer Match works in Google Ads and how to get the most out of it for e-commerce.
For Shopify stores with reasonable order history, this is a layer of sophistication that most accounts never use — and it's one of the cleaner ways to improve ROAS without increasing total spend.
| Campaign | ROAS (month 1 after rebuild) | Conversion Rate |
|---|---|---|
| PMax Selected Products | 7.67x | 6.07% |
| Standard Shopping | 6.34x | 6.69% |
| Search | 3.89x | 8.23% |
| Total Account | 6.63x | 6.38% |
