What is a Publisher?

In mobile marketing, a publisher is any person or company that publishes content via a site, app or blog. Publishers sell space on these platforms to app developers (buyers) and agencies, and advertisers use this space to run their ads. Advertisers create ads and pay publishers to display them.

For example, a brand wants to display a promotion for their newest product to their target audience. This brand will buy ad space from a publisher to display this promotion. Networks act as the middleman between publishers and advertisers by connecting developers and agencies with publishers.
