What is a Publisher?
In the mobile ad industry, a publisher is a person or company that owns an app or a website and sells ad space to advertisers in order to monetize it.
Publishers stand on the selling side of the ad market. Typically, they do not sell their ad space directly to advertisers. Instead, they sell it to ad networks that bundle ad inventory from many apps and placements to offer it to advertisers afterward.
