Google Ads GA4 Purchase Tracking

Google Ads GA4 purchase tracking alignment ensures that your revenue figures, ROAS calculations, and purchase attribution are consistent between Google Ads and GA4 — eliminating the confusion that arises when two platforms report different revenue for the same campaigns. The most common cause of discrepancy is that GA4 ecommerce purchase events and Google Ads conversion tags are configured with different value definitions: one includes tax and shipping, the other excludes them; one deduplicates on transaction ID, the other doesn't; one uses order value excluding returns, the other uses gross revenue. Getting these aligned produces a reporting environment where CFOs, marketing directors, and campaign managers all see the same revenue numbers. Adslytics implements Google Ads GA4 purchase tracking alignment by auditing the current purchase event configuration in both platforms, standardising the revenue value definition, ensuring transaction ID deduplication is consistent, importing the GA4 purchase event into Google Ads as a conversion action (or cross-referencing with native Google Ads conversion tags), and aligning attribution windows. We also configure the GA4–Google Ads account link for cost data visibility in GA4 and verify that ROAS calculations in both platforms use consistent revenue definitions. The outcome is purchase tracking you can trust in both platforms — with a documented understanding of any remaining differences.
