Supply Path Optimization (SPO): How to Maximize Programmatic Efficiency

Supply Path Optimization (#SPO) has been one of the most discussed topics throughout 2025 at conferences, events, and strategic industry discussions. But what does SPO really mean, and why has it become a key factor for both publishers and buyers in the programmatic ecosystem?

SPO is not just a buzzword — it is a strategic lever that enhances transparency, efficiency, and investment outcomes in digital advertising.

What is Supply Path Optimization?

In simple terms, SPO refers to optimizing the path that inventory takes from the publisher to the end buyer, ensuring that each actor in the chain adds real value.

Contrary to some beliefs, SPO is not about indiscriminately removing intermediaries. The key is identifying which partners truly add value, improving signal quality, and reducing noise in the programmatic chain.

Why SPO is Reshaping the Ecosystem

1. Smarter Paths, Not Fewer Steps

A smart SPO strategy ensures that every partner contributes effectively. This:

• Enhances signal quality

• Removes unnecessary intermediaries that don’t add value

• Connects demand and supply more efficiently

Unfortunately, the market has experienced certain “bad practices” from actors who have not properly managed their roles, resulting in breaks in the optimization chain, lack of transparency, and reduced efficiency. However, not all intermediaries have zero value, and each should be evaluated fairly and strategically.

2. Transparency That Drives Better Decisions

SPO allows publishers and buyers to understand who adds value and how, enabling more informed decisions regarding investments and partnerships. This leads to:

• Cost optimization

• Improved performance

• Selection of partners who truly elevate results

3. Quality and Performance at the Core

By refining the supply path:

• Waste is reduced

• Bid effectiveness increases

• Premium inventory aligns better with qualified demand

In other words, SPO ensures ads reach the right place and generate real impact.
