Floodlight
Google Tag Manager supports Floodlight Counter and Floodlight Sales tags. The Floodlight Counter tag is used to count the number of times that users have visited a particular page after an ad is viewed or clicked, and the Floodlight Sales tag is used to measure the quantity and value of purchases.
Note: Floodlight tags are occasionally referred to as "container tags". This should not to be confused with the concept of a Tag Manager container.
