A marketer added a conversion tracking tag to a landing page on their company's website. When analyzing purchasing data, they found duplicate conversions. How can the marketer remove duplicate conversions from their conversion count?

The selection is correct because modifying the event tag to capture a unique order ID allows Google Ads to identify and de-duplicate multiple pings from the same transaction, such as when a user refreshes the "Thank You" page or returns to it from a bookmark. By including a transaction ID variable (e.g., order_id) within the conversion tracking code, the system cross-references each reported conversion against previously recorded IDs; if a match is found, the second instance is ignored, ensuring the conversion count accurately reflects unique business outcomes rather than technical redundancies. This technical adjustment is the industry-standard method for maintaining data integrity and preventing the artificial inflation of ROI metrics within campaign reporting.
