MarTech Landscape: What is a supply-side platform (SSP)? - MarketingLand | The MarTech Digest |
Supply-side platforms — also called sell-side platforms or yield optimization platforms — are used by digital publishers to manage the sale and fulfillment of their advertising “supply” and ultimately, get the highest prices for their ads.

SSPs are software platforms that function similarly to their counterpart, the demand-side platforms (DSPs) advertisers use to buy digital advertising programmatically. However, SSPs are designed specifically to help publishers sell ad impressions — mobile, video, display and so on — at maximum CPMs (cost-per-thousand impressions).
