Publisher ID
In plain English
What does Publisher ID mean?
The identifier of the site or app that showed your ad, passed by the ad network so you can whitelist or blacklist sources.
Publisher (or site/zone) IDs are the most important optimisation lever on pop, push and native traffic: a handful of publishers usually produce most conversions while others burn budget. Pass the ID to your tracker via a macro, then whitelist winners and blacklist losers.
