GA4 + GTM
Setup & Audits for Shopify
Solo Media Group is one of the top Shopify agencies for GA4 and tracking setup, and the reason is that we fix tracking at the source, not just in reports. Many Shopify stores count purchases twice, miss checkout events or ignore consent, so marketing decisions rest on bad data. We set up and audit GA4 and Google Tag Manager so your numbers are accurate and explainable.
What usually goes wrong with GA4 on Shopify?
The most common problems are duplicate purchase events, missing checkout events, tags that ignore consent and inconsistent UTM tagging. Each one quietly distorts revenue and channel reports. An audit finds them by comparing GA4 against Shopify's own orders.
Symptom: GA4 revenue higher than Shopify. Fix: one purchase tag, deduplicated by order ID.
Symptom: funnel drops to zero at checkout. Fix: checkout events tracked through Shopify's supported methods.
Symptom: tracking before visitors agree. Fix: tags tied to Shopify's consent signals.
Symptom: the same source split into several. Fix: a shared UTM naming sheet.
Symptom: AI visits lost in referrals. Fix: a custom channel for AI assistants.

How does cookie consent affect GA4 on Shopify?
Shopify's cookie banner passes each visitor's choices to its Customer Privacy API, which decides whether analytics and marketing tags can run. Tags should follow those choices. Where consent rules apply, visitors who decline won't be fully tracked, so GA4 will undercount compared with Shopify's orders.
See Shopify's Customer Privacy API. For EU and German consent rules, see our Germany and EU compliance checklist.
Why don't GA4 and Shopify reports match?
Because they count differently. Shopify uses a last non-direct click attribution model over 30 days by default, GA4 uses its own model, and consent choices limit what GA4 sees. Small differences are normal; large ones usually point to a setup problem an audit can find.
OUR APPROACH
We fix tracking inside the store itself, because we build Shopify stores every day.
What does a GA4 audit include?
A GA4 audit checks your events, purchase accuracy, consent handling, UTM tagging and channel groupings, then gives a prioritized fix list.
We compare GA4 with Shopify order data for a sample period, so every finding is backed by evidence.
