Google Ads Purchase Tracking

Google Ads purchase tracking is the most critical measurement configuration for any ecommerce business running paid search or shopping campaigns. When Google Ads purchase tracking is set up correctly — firing on the order confirmation page with the actual transaction value, deduplicating correctly to count once per order, and including Enhanced Conversions data for improved match rates — Smart Bidding algorithms have the precise revenue signal they need to optimise toward profitable transactions. The difference between correct and incorrect purchase tracking is not a data quality nuance — it is a direct determinant of campaign profitability, and fixing broken purchase tracking routinely delivers ROAS improvements of 20–50% within the first campaign cycle after correction.

Our Google Ads purchase tracking service implements the complete configuration: a GTM purchase tag that fires on the order confirmation page (and only the order confirmation page), reads the actual transaction total, tax, and currency from the data layer, passes the correct conversion ID and label to the Google Ads conversion action, and uses transaction ID deduplication to prevent any order from being counted twice. We configure the Google Ads conversion action with the correct counting method (every conversion, not one per click, for purchases), attribution model (data-driven where eligible), and conversion window aligned with your typical purchase consideration period. Enhanced Conversions are configured to pass hashed email and phone number from the confirmation page, improving match rates for users who are logged into a Google account. Every component is verified with a real test purchase before handover.
