A marketer wants to track more than just sales and visits; they need to capture specific promo codes used during a transaction. Which feature of Floodlight should they use?

Custom Floodlight variables are designed to capture information beyond standard conversion details such as visits and revenue. Google states that they let advertisers pass additional contextual values with Floodlight tags, using keys like u1, u2, and so on. That makes them the correct feature for recording transaction-specific data such as a promo code used during checkout. Those values can then be used in reporting, which is why this feature fits a need for richer conversion detail instead of basic sales counting alone. Google Help+2Google Help+2
