Bid requests occur when publishers submit information about their available ad inventory to SSPs, ad networks, or ad exchanges, providing specifics about the impressions on offer, such as the platform, user, and floor price. These details are sent to DSPs via the RTB system as bid requests. If the request matches the advertiser’s criteria, they can reply, via the RTB system, with a bid (a bid response).
