From Amazon's Advertising API:

The "Tactic" column in Amazon Advertising can be used for various campaign types. It helps you track the specific strategy or approach you're using within your campaigns. Whether it's for sponsored products, sponsored brands, or other types of campaigns, the "Tactic" column lets you see at a glance how different strategies are performing.

The "Tactic" column is not a tag or variable set within Ad Badger. Instead, it is a feature provided by Amazon Advertising itself. It allows advertisers to categorize and track different strategies or approaches used in their advertising campaigns, regardless of the campaign type (e.g., sponsored products, sponsored brands).
