As programmatic faces signal degradation, agentic advertising offers a solution

Before the term signal loss gained popularity, media owners and their advertising partners grew accustomed to “hacking” the programmatic auction to increase the value of their inventory. While those reactions addressed the symptoms, they never solved the root issue.

The challenge is that the structure of a real-time auction forces each party to use only a small amount of signal due to the overwhelming complexity of trying to plan, buy and optimize across hundreds of permutations.

Agentic advertising is rapidly turning this paradigm on its head. This approach will radically shift the value of premium publishers within the advertising ecosystem while also driving better efficiency and outcomes for agencies and advertisers alike.

When premium inventory doesn’t stand out

While publishers know their audiences are valuable, if buyers can’t accurately find or evaluate that inventory at the speed programmatic demands, everyone loses.

Publishers remain drastically underpaid, advertisers remain frustrated by their results, the most valuable data is never used in this process and campaigns remain focused on outcomes that don’t translate into real sales.

Deal-based packaging, programmatic guarantees and audience curation have become popular workarounds for the challenges in the programmatic infrastructure. The common goal is to bring ad buyers and sellers closer together to discover audiences, share insights, create plans and measure success.

Unchanged, the traditional programmatic workflow doesn’t allow for that kind of real-time collaboration. The industry adopted real-time bidding to overcome the slow process of negotiating direct deals, but it has left little room for audience-driven targeting that yields better performance.

Agentic advertising reimagines the transaction, bridging the gap between programmatic’s speed and direct’s curated placement.

Agentic advertising shifts how demand finds audiences

For the first time, workflows are being developed that can actually bring buyer intent directly to the rich data across the publisher ecosystem. Emerging protocols like the Ad Context Protocol allow for data-driven allocation and planning with natural language interfaces.

Buyers are already deploying agents to rapidly evaluate publisher inventory and automate campaign decisions. Premium publishers have started releasing media and audience packages for autonomous negotiation based on campaign goals.

What’s emerging is a more data-driven buying and selling process, built on organized, interoperable audience data. Agentic advertising makes premium audiences more accessible to buyers and condenses the deal timeline.

Today, that means responding to buyers faster and with better data. RFP responses that used to take days of manual back-and-forth can be turned around in a fraction of the time. With Optable’s Audience Agent, publishers can uncover and organize audience segments, then draft RFP responses that accurately reflect the value of their inventory. 

That’s the foundation for agentic collaboration: publisher and buyer systems interfacing directly, with identity and interoperability doing the heavy lifting. To make that possible, publishers need:

• High-quality data: Clean, accessible data is what buyer agents can actually evaluate, act on and prioritize.
• Resolved identity: Audiences resolved across a wide range of identifiers (including hashed emails, UID2 and more) will give buyers more signal to match against, meaning faster audience discovery and less wasted spend on both sides.
• Interoperability: Agentic collaboration needs a shared language for audience discovery and deal negotiation without fragmentation. AdCP, the emerging cross-platform protocol for agent-to-agent communication, supports interoperability at scale.

The window to get ahead is right now

The problem isn’t that publishers don’t have valuable data. It’s that their data isn’t legible to the buy-side agentic systems making deals.

Publishers should ask themselves: Can a buyer evaluate my audience without a sales call? If not, the company’s data infrastructure might need work. As a baseline, that means ensuring audience segments are structured and machine-readable.

Signal degradation isn’t going to solve itself, and the open auction won’t self-correct to reward publisher differentiation. Adding more automation on top of degraded signals won’t fix the problem.

The solution requires better data and smarter systems. The agentic model asks publishers to make their data legible, rather than rebuild their infrastructure from scratch.

Seller and buyer agents are already negotiating deals directly, routing deal execution through the same programmatic infrastructure the industry already uses.

A solid identity foundation ensures inventory is visible to buyer agents today and ready for agentic collaboration when it arrives.
