As China's advertising media market enters a stage of 存量竞争 (competition for existing market share), the role of agencies is increasingly evolving from "execution intermediaries" to more of "resource integrators."
In this process, Principal Media has gradually become a frequent practice within the industry.
Leveraging their purchasing volume and negotiation advantages, agencies secure exclusive or semi-exclusive media resources, which are then offered to advertisers under labels such as "Principal Media," "Proprietary media," or "Preferred Resource Packages." Etc.
Globally, Principal Media is not a new concept.
In some markets, it is considered a business model that enhances agency efficiency, hedges against price fluctuations, and strengthens bargaining power. However, almost all related discussions revolve around the same prerequisite: transparency and governance structures.
In recent years, debates surrounding Principal Media have not diminished but have instead become more frequent.
In our view, the long-term difficulty in regulating such practices stems mainly from two structural reasons:
With slowing media market growth and pressure on service fee margins, Principal Media represents a significant, directly monetizable revenue stream for agencies. It's understandable that agencies would prioritize its use.
The "comprehensive value narrative" used to package Principal Media often downplays or obscures potential risks, leaving little room for its independent scrutiny at the decision-making level.
While conducting RuiPact (contract performance verification: Safeguarding Agreements and Mitigating Enterprise Risk: https://ruiview.com/ruipact-en) project for a leading apparel brand, we gained grounded insights into the actual operation of Principal Media.
- Client: Leading apparel brand
- Media Involved: Online, Out-of-home (OOH), Print, social media
- Campaign Period: 2025
- Project Type: RuiPact (contract performance verification)
- Project Objectives:
- Verify fulfillment of existing contractual entitlements.
- Highlight potential risks within the contract structure.
The project did not start with the preconceived notion of "investigating Principal Media." This issue naturally surfaced during the cross-verification of contract terms and actual execution orders among other things.
By analyzing the contract between the advertiser and the media agency and execution orders for media buys, we identified three key issues which have the potential for value loss for advertisers:
- Under the existing contract framework, the agency has no obligation to separately disclose the use of Principal Media or to obtain specific confirmation from the advertiser for its use. In other words, whether and how to use it is entirely at the agency's discretion.
- Within the scope of sampled orders for this project, over 30% orders involved Principal Media resources valued at tens of millions, indicating significant spending carried out without the advertiser's knowledge of from where it is bought from.
In the sampled execution orders, we found:
- No unified, clear labeling rules for Principal Media resources.
- Some resources had no property description whatsoever. This makes it difficult for advertisers to identify which resources belong to the agency's proprietary system during post-campaign analysis or cross-project comparisons which leads to accountability problems in the longer run.
- Within the sampled scope, the same media placement was sometimes Principal Media in one order and not in another.
- Some Principal Media placements had notes within the specific placement name, while others used a unified note for the entire media order.
- Among orders with similar conditions, some used Principal Media while others did not. However, no verifiable advantages were evident across comparable key dimensions like price, resource quantity, or exposure conditions. The use of Principal Media seemed more like an operational habit than a strategic choice based on clear value judgment.
- Within the sampled scope, we found several similar projects involving the same or similar media placements, but the differences in discounts or volume achieved by using (or not using) Principal Media were not significant. The logic for its use lacked a clear and simple reason, what’s the use of Principle media for the advertiser?
Based on the findings, we recommend advertisers negotiate and adjust the following three aspects with their agencies within the existing cooperation framework:
Clearly define the agency's disclosure responsibilities when using Principal Media, including but not limited to:
- resource property description
- scope of use
- confirmation mechanisms etc.
Principal Media should not be merely an "internal advantage narrative." It must be accompanied by a clear logic for proving value. If there is no clear discount or resource增量 (increment), there is no necessary justification for its use. Examples include:
- Price Advantage: Is there a lower discount?
- Resource Increment: Does the same total buy price yield more resources?
- Scheduling or Stability Advantage: Are there shorter lead times, more flexible order change/cancellation policies?
This value delivery proof should serve as a key basis for the agency's recommendation to use Principal Media.
Define key elements surrounding Principal Media use, such as:
- approval cycle
- approval path
- budget allocation percentage
- value proportion, etc.
...and create an independent, executable, and auditable standard operating procedure (SOP).
