CONVERSION TRACKING QA

Your Canadian Conversion Tracking Is Probably Double-Counting Shopify Purchases

Shopify stores connected to both GA4 and Google Ads commonly fire the same purchase event twice — once through the GA4 tag and once through the Google Ads conversion tag in the same GTM container. Smart Bidding trains against double the real purchase volume, over-bids on traffic, and the inflated ROAS figure masks what is actually happening. PIPEDA compliance in conversion event configuration compounds the risk for businesses collecting consent before tracking.

This is for you if

Who This Is For

Shopify store owners running Google Ads and Meta Ads in Canada — Your Shopify store has both GA4 and Google Ads conversion tracking active. You have never run a systematic check to confirm whether both are firing independently without duplication on your order confirmation page. If they are both counting the same purchase event, Smart Bidding has been training against a conversion volume that is roughly twice the real figure — which means every ROAS figure you have reported in the last year is likely incorrect.

Marketing directors managing multi-channel paid budgets in Canada — You are accountable for paid performance across Google Ads, Meta, and potentially LinkedIn. The conversion figures across platforms never reconcile, your agency reports each channel in isolation, and you have no reliable single view of what paid acquisition actually produces. You need a systematic QA of every conversion action across every platform before you make budget decisions for the next period.

Canadian businesses with PIPEDA consent obligations — Canada's Personal Information Protection and Electronic Documents Act (PIPEDA) requires that personal data — including data used for conversion tracking and remarketing — is collected with informed consent. If your conversion tags fire before a user has accepted your consent notice, or if your GTM container is not configured to respect consent signals, you have both a compliance exposure and a data quality problem. The QA reviews consent-gating of your conversion tags as standard for Canadian accounts.

Businesses that migrated to GA4 and have not audited tracking since — The GA4 migration introduced conversion tracking gaps and duplications in a large proportion of Canadian accounts. If your GA4 events were not systematically re-verified after the migration, there is a meaningful risk that legacy conversion tags are still active alongside new ones — producing duplicate data that has been feeding your bidding algorithms for months.

What's broken

What we find in the majority of Canadian accounts

Shopify and GA4 double-counting purchase events

This is the most common tracking error in Canadian e-commerce accounts. When a Shopify store sends purchase data to GA4 via the standard Shopify-Google integration, and a separate Google Ads conversion tag also fires on the Shopify order status page — both in the same GTM container — every purchase is counted twice. The Google Ads conversion action reports double the real purchase volume. Smart Bidding optimises against that inflated figure, sets bids accordingly, and the reported ROAS bears no relationship to actual revenue.

Meta Pixel not passing correct order values after iOS updates

Meta's Pixel implementation on Shopify stores in Canada has been widely disrupted by iOS privacy changes. In many cases the Pixel continues to fire and Meta continues to report conversions — but the order values are missing, incorrect, or estimated by Meta's modelling rather than drawn from real transaction data. Campaigns optimised against modelled revenue figures are not being trained on accurate signals, and the discrepancy between Meta-reported and Shopify-actual revenue can be substantial.

Conversion tags firing before consent is obtained

Under PIPEDA, conversion tracking that processes personal data requires informed consent before the data is collected. Many Canadian GTM setups fire Google Ads and Meta conversion tags on page load — before the user has interacted with the consent notice. This means conversion data is being collected without the required consent basis, creating legal exposure and producing a dataset that includes users who subsequently declined tracking.

Attribution gaps between GA4, Google Ads, and Meta

Canadian accounts running Google Ads and Meta simultaneously frequently cannot reconcile conversion figures across the three reporting surfaces. GA4 shows one number, Google Ads shows another, and Meta shows a third — and the differences are not explained by attribution window differences alone. Double-counting, modelled data, and missing events each contribute to a picture of performance that cannot be trusted without a systematic reconciliation.

What we engineer

What the Conversion Tracking QA covers

Shopify purchase event deduplication audit

We specifically check for duplicate purchase events firing across GA4 and Google Ads for Shopify stores. This includes reviewing the Shopify-Google integration configuration, the GTM tags firing on the Shopify order status page, and the conversion actions in Google Ads to identify exactly where double-counting is occurring. Where duplication is confirmed, the fix instructions specify whether to resolve it at the GTM trigger level, the conversion action level, or by adjusting the Shopify-Google integration settings.

Meta Pixel and Conversions API review

We review the Meta Pixel implementation on your Shopify store against actual transaction data. We check whether the Pixel is passing order values correctly or whether Meta's modelled data is being used to fill gaps introduced by iOS changes. We also check whether the Meta Conversions API is in place to supplement browser-based tracking — which is the standard fix for iOS-related Pixel data loss.

PIPEDA consent compliance review

We check whether your GTM container is configured to consent-gate conversion tags — meaning that Google Ads and Meta tracking tags do not fire until the user has accepted tracking in your consent notice. We verify whether your Consent Management Platform is correctly integrated with GTM and whether consent signals are being respected before any tracking fires. Where consent-gating is absent or misconfigured, the fix instructions are included in the report.

Full GTM container audit

We review every tag, trigger, and variable in your GTM container. We identify tags from previous setups that remain active alongside current ones, verify that all conversion tags have correct trigger conditions, and check deduplication logic across all platforms. For Shopify accounts with multiple tag implementations introduced during different agency or developer relationships, this review commonly surfaces issues not visible from within the ad platform interfaces.

Attribution gap analysis across Google Ads, Meta, and GA4

We pull conversion data from each platform for the same period and reconcile the figures. Where they diverge materially, we identify the specific cause — Shopify purchase duplication, Meta modelled data, consent-gating gaps, or attribution window differences — and document what an accurate conversion picture looks like when each error is corrected.

Common questions

FAQ

What does the Conversion Tracking QA cover for Canadian accounts?

The QA audits every conversion action across Google Ads, Meta Ads, GA4, and GTM — checking for broken tags, duplicate events, missing conversions, and attribution gaps. For Canadian accounts specifically, the Shopify purchase event deduplication check and the PIPEDA consent compliance review are included as standard. You receive a written report with severity ratings and exact fix instructions for every issue found.

How does Shopify cause Google Ads to double-count purchases?

When a Shopify store uses the Shopify-Google integration to send purchase data to GA4, and GA4 conversions are then imported into Google Ads, a purchase event enters Google Ads through that route. If a separate Google Ads conversion tag is also placed in GTM on the Shopify order status page — which is common when a GTM setup has been modified over time — the same purchase is counted twice in Google Ads. Smart Bidding then trains against double the real purchase volume. The QA identifies whether this configuration exists in your account and provides the exact fix.

Does the QA include a PIPEDA compliance review?

Yes. The Canadian Conversion Tracking QA includes a review of your GTM container's consent-gating configuration against PIPEDA requirements. We check whether conversion tags fire before or after user consent is obtained, whether your Consent Management Platform is correctly integrated with GTM, and whether consent signals are being respected. Where compliance gaps are identified, they are documented with fix instructions. We flag the issues — acting on them with legal guidance is your responsibility.

We use Shopify with a third-party analytics integration. Does that affect the QA?

Third-party Shopify analytics integrations — such as Elevar, Triple Whale, or Littledata — change how purchase events are sent to Google Ads and Meta. The QA is adapted to account for whichever integration is in place. When a third-party integration is active, we review both the integration's data layer configuration and the GTM tags sitting alongside it to identify any duplication or gaps introduced by the combination.

How long does the QA take?

The report is delivered within 5 business days of receiving access to all platforms. If access to any platform is delayed, we communicate the impact on the timeline immediately. Most Canadian QA engagements are completed within the 5-day window without issue.
