Supply Path Optimization (SPO)

Supply Path Optimization (SPO) är den praxis genom vilken annonsköpare identifierar och föredrar den kortaste, billigaste och mest transparenta vägen för att köpa en given visning, genom att ta bort överflödiga mellanhänder som lägger till avgifter utan att tillföra värde. Eftersom samma inventarier ofta finns tillgängliga via flera vägar handlar SPO om att välja den bästa.

How it works#

Buyers compare the routes an impression travels through the Ad Supply Chain, measuring fees, win rates, latency, and how often inventory is misrepresented. They lean on the SupplyChain Object (schain) and sellers.json to verify that every hop is an authorized seller, then consolidate spend onto the cleanest direct paths, often buying closer to the publisher and dropping resellers that simply mark up the same impression.

Why it matters#

SPO can meaningfully lower effective media costs and reduce exposure to fraud and unauthorized Resold Inventory / Demand Partner chains. For sellers, being on the shortest path means more of the advertiser's dollar reaches them. SPO has become a standard discipline for programmatic teams precisely because supply chains grew long and opaque.
