When Google forced the Smart Shopping to Performance Max migration, it carried over your existing campaign structure — including all its gaps in audience signals, asset quality, and conversion tracking. Canadian advertisers who have not audited their PMax campaigns since the migration are very likely running on defaults that are costing them budget every day.
Canadian Shopify Stores That Migrated From Smart Shopping
Canadian Retailers Spending $10,000+ CAD Per Month on Google Ads
Canadian Advertisers Concerned About PIPEDA Compliance for Audience Uploads
When Google migrated Smart Shopping campaigns to PMax, it created asset groups using whatever creative was already in the account and applied generic audience signals. It did not restructure campaigns by product category, it did not upload CRM data as audience signals, and it did not add brand exclusion lists. Most Canadian advertisers are still running on these migration defaults eighteen months later.
PMax will serve on branded searches unless brand exclusion lists are explicitly configured. For Canadian retailers with established brand recognition in Toronto, Vancouver, or Calgary, a significant share of reported PMax conversions may be coming from customers who were already searching for the brand name. This makes the campaign look efficient while doing little to grow the actual customer base.
Default PMax audience signals are based on Google's interest and in-market categories. For most Canadian advertisers, these categories describe a broadly relevant population — not the specific customer segments that convert for their business. Without CRM-based signals, the algorithm spends the learning phase on exploratory traffic rather than working from a verified buyer profile.
A single asset group covering your entire Shopify catalogue means the algorithm cannot distinguish between high-margin products and low-margin ones, between seasonal bestsellers and evergreen lines, or between products with very different buyer journeys. The result is a campaign that produces averaged performance across all products rather than optimising toward your best-performing categories.
We audit every conversion event: Google Ads tags, GA4 imports, and any Shopify-specific purchase tracking configurations. Canadian Shopify stores frequently have duplicate purchase events from both the Shopify Google channel app and manually placed GTM tags. We resolve these conflicts and verify that purchase values are being reported accurately in CAD before any rebuild begins.
We restructure the PMax campaign into asset groups that reflect your actual product or service segmentation. Each group receives fresh headlines, descriptions, and imagery specific to that category. For Canadian retailers with seasonal buying patterns, we build seasonal asset group variants alongside evergreen ones so the campaign can shift creative emphasis without structural changes.
We work with your CRM or email platform to build customer match lists for audience signal uploads. For Canadian advertisers, we document the data handling process and confirm that it aligns with PIPEDA requirements — specifically the appropriate notice, consent, and data minimisation expectations that apply to using customer personal information for digital advertising purposes.
We implement brand exclusion lists at the PMax campaign level and structure any separate Search campaigns to capture branded traffic with appropriate priority. For Canadian advertisers with both English and French brand searches, exclusion lists cover both language variants. We document the exclusion setup and the rationale so it can be maintained as the brand evolves.
We build a reporting framework that separates PMax's new-customer contribution from branded and retargeting activity. For Canadian retailers with regional variation in performance across Toronto, Vancouver, and Calgary, we include geographic breakdowns where the data supports it. Weekly performance updates are included for the first month.
Google migrated all Smart Shopping campaigns to Performance Max in September 2022. The migration carried over your existing budget, bidding strategy, and whatever creative assets were in the account. It did not restructure your asset groups, upload audience signals from your CRM, or add brand exclusion lists. The result is that most Canadian advertisers are running PMax with the minimum viable configuration Google needed to complete the migration, not with a setup optimised for their business.
Customer match uploads involve hashing and transmitting personal information — typically email addresses — to Google for audience matching. Under PIPEDA, this requires appropriate notice to your customers about how their data is used and a legal basis for processing. We document the upload process and the relevant PIPEDA considerations as part of our Canadian audience signal deliverable. We recommend you review the documentation with your privacy counsel before the upload proceeds.
PMax can target French-language audiences with French-language asset groups, but this requires building separate asset groups in each language — not a translation layer on top of English copy. For Canadian advertisers with bilingual audiences, we assess the volume and value of the French-language opportunity during the audit phase. If it is material, we build it into the rebuild plan. If not, we document why English-only targeting is the appropriate starting point.
The most common Shopify tracking issues we find in Canadian accounts are duplicate purchase events from overlapping tag configurations, incorrect CAD purchase values caused by currency conversion errors, and missing conversion data for orders completed through third-party payment gateways. We identify all of these during the five-day audit. You will receive a conversion tracking report that documents every event, every firing condition, and every discrepancy before we make any changes.
No. The audit is conducted on a read-only basis for the first five days — we review the account without making changes. The rebuild happens in a structured sequence that we agree with you before any live changes are made. We typically stage the transition during a period of lower commercial risk for your business rather than mid-peak-season, and we include a rollback plan in the rebuild documentation.
Google moved your campaign to a new format, not to a better setup. The structural work — CRM signals, brand exclusions, category-level asset groups, accurate CAD conversion tracking — still needs to be done. The five-day audit tells you exactly what was missed and what it costs you each month. There is no retainer and no obligation beyond the audit.
