Frequently asked questions
Which should I trust for revenue?
Shopify always. GA4 is directionally correct on revenue but will always show 5-15% variance vs Shopify because of consent, ad-blockers and cross-device gaps.
Do I need GA4 if I have Shopify?
Yes, if you run any paid media or care about SEO. GA4 is the only place you see funnel drop-off, source attribution and cross-device journeys.
