Ad tag targeting macro reference
Many VAST servers use tag variables to optimize fill and provide more information on how ads are being viewed. JWP supports a number of variables that can be added to your VAST tag URL. Once an ad call is made by JWP, the variables will be replaced accordingly.
Targeting macros are used by both client-side and server-side ads servers. It is not uncommon to add 10+ macros to a single ad tag.
The following VAST tag example contains the __random-number__ macro.
https://example.adserver.com/vastResponse.xml?cb=__random-number__
In the previous example, __random-number__ is replaced with a random number (cachebuster). The ad server will receive an ad tag that looks similar to the following: https://example.adserver.com/vastResponse.xml?cb=98475983745983752
If you are unsure how to fill out your ad tag macros, you will need to contact your ad network. They will inform you of any parameters you would add to boost your CPM. You can also find out if you need to add custom metadata to the video in a way that you can send to the player.
VAST
You may only use a specific ad tag macro type once in a single ad tag. As a workaround, try inserting the desired value via JavaScript concatenation in the ad tag URL string.
