AdExplainer: What Is Supply-Path Optimization (SPO)?
The complexity and lack of transparency in the programmatic ad buying ecosystem makes it hard to understand who you’re buying from and how big of a bite they’re taking out of a buyer’s ad spend. Hence the need for supply path optimization (SPO). Simply put, SPO is about buyers identifying the most efficient connections and using them to transact with sellers. The goal is to stop buying through inefficient or expensive paths to supply.
