- Set up Custom Floodlight Variable using bulksheets
- Set up Custom Floodlight Variable using the relevant engine frontend
- Set up an additional Floodlight tag and pass the shipping cost through the revenue field
- Set up Custom Floodlight Variable as a metric
The correct answer is: Set up Custom Floodlight Variable as a metric
Explanation: Before you set up custom metrics and dimensions in Search Ads 360, you need to create custom Floodlight variables in the Campaign Manager advertiser that is associated with your Search Ads 360 advertiser. Metric: The variable’s value will be aggregated. For example, if the variable is an item count for conversions or is keeping track of overall shipping costs for purchases, you’ll want to indicate a metric data type. Search Ads 360 will add these values together each time Floodlight sends an update for the variable, and you’ll see the total number of conversions or the total shipping costs when you add the column to your Search Ads 360 reports.
