Your new bookstore client is running a campaign for its new training series that kicks off with a how-to brochure. They're using a counter tag within their Floodlight tags in Campaign Manager 360.Which counting method should you use if you want to measure how many users downloaded the brochure?

In Campaign Manager 360, using the unique counting method with a Floodlight counter tag ensures that each user is counted only once, regardless of how many times they download the brochure, providing an accurate measure of how many individual users engaged with the training series rather than inflating counts from repeated actions by the same user.
