we are using the native Google Analytics integration through Shopify. However, the discrepancies between Analytics & Shopify are huge.
GA shows way less visitors, sessions & transactions
Visitors: 35 % less in GA
Sessions: 18 % less in GA
Transactions: 27 % less in GA
While I totally understand that there are some discrepancies between the two systems, 25 % of transactions missing is way higher than the usual. I have talked to a few other shop owners and the discrepancies are way lower.
