Google Adx (formerly DoubleClick Ad Exchange) is an ad exchange integrated with Google Ad Manager 360.
It’s a programmatic advertising platform that connects sellers (website and/or mobile app publishers) and buyers (media agencies, advertisers, trading desks) to buy and sell their ad inventory.
Google Adx is invitation-only, but publishers who do not meet Google’s eligibility criteria can gain access by working with accredited partners like Hitopic.
Because it is associated with the Google brand, Adx has the largest network of active buyers and sellers in their tool, giving you direct access to premium demand from the largest advertisers in the global ad market.
