As digital advertising matures, one foundational truth becomes increasingly clear: ad tech works best when its roles are clearly defined and independently executed. In a complex ecosystem where DSPs, SSPs, and publishers must work together but serve distinct interests, any overlap of responsibilities can introduce subtle but powerful conflicts of interest.
Yet in recent years, some of the biggest players in the industry: Google, Amazon, and The Trade Desk among them have blurred these lines in ways that are reshaping the conversation about transparency, neutrality, and trust in the ad supply chain.
The question isn’t whether these companies are innovating, they are. The question is whether the industry benefits when the power to buy, sell, and control the auction sits in a single set of hands.
At ConnectAd, we believe in clean separation, and here’s why that matters more than ever.
1. Checks and Balances Keep the Ecosystem Healthy
The programmatic marketplace is a delicate balance of supply and demand. DSPs represent the advertiser’s interest, to buy quality impressions efficiently. SSPs represent the publisher’s interest, to curate and sell inventory at the highest yield. When these functions are kept separate, the market benefits from competition, negotiation, and transparency.
However, if one company owns both sides of the transaction, there’s no one to question or counterbalance its decisions. Without that push-pull dynamic, decisions that affect pricing, auction dynamics, or even data usage can become opaque, and participants have fewer tools to verify fairness.
This is why traditional exchanges and marketplaces, whether in finance or media, are built on separation of powers. It’s not about bureaucracy; it’s about accountability.
2. Blurring Roles Introduces Inherent Contradictions
Several major players in ad tech have begun consolidating roles in ways that are changing how auctions work.
The Trade Desk and OpenPath
With OpenPath, The Trade Desk has created direct connections to publisher inventory, cutting out the traditional SSP layer. While this may improve efficiency and reduce fees for buyers, it also changes the dynamics of the auction. The same platform that’s buying media now plays a role in selecting which media is available, raising questions about neutrality and yield optimization for publishers.
TTD has stated that their goal is to reduce unnecessary hops and improve transparency for advertisers. That may be true, but it also places them in a position where they are optimizing for both sides of the trade, a situation that introduces tension between cost control and inventory value.
Amazon’s Expanding Role in Prebid
Amazon’s recent entry into Prebid with its own SSP adapter signals another significant move. As a DSP (Amazon Ads), an SSP (through TAM and now Prebid), a cloud services provider, and a publisher itself, Amazon touches nearly every layer of the ad stack.
To their credit, Amazon has introduced tools that improve monetization and competition. But when the same company controls the infrastructure, the inventory, and the buying tools, it becomes harder for outside observers to independently verify fairness or auction integrity. It’s not about ill intent, it’s about the risks of consolidation.
Google’s Integrated Ad Stack
Google has long operated across the stack with DV360 (DSP), Google Ad Manager (SSP), and AdSense/YouTube (publishers). While Google has made efforts to increase transparency (e.g., through initiatives like ads.txt and seller.json), its dominance remains a source of scrutiny.
As noted by AdExchanger and others, there is ongoing regulatory interest in whether a breakup of Google’s ad tech business might restore greater competition. The core issue isn’t about Google’s capabilities, it’s about whether any company can be a neutral broker while also operating as both buyer and seller.
3. Neutrality Requires Structural Independence
When one platform is responsible for both demand and supply functions, whose goals take priority when tradeoffs arise? Is the system truly prioritizing the best interest of the buyer or seller, or optimizing for internal revenue?
That’s not a judgment about the motives of any particular company, it’s a question about what’s structurally possible.
In any marketplace, transparency doesn’t just depend on open reporting or access to dashboards. It depends on a foundation where parties have clearly defined, independent roles. Without that, even the most sophisticated tools can’t fully offset the risk of conflicts.
4. Why ConnectAd Stays Focused on One Side
At ConnectAd, we’ve made a deliberate decision to serve one side of the table, and to do it with full dedication and transparency.
We don’t operate a DSP. We don’t own inventory. We don’t mix our incentives.
Our only goal is to help our clients maximize their performance, whether that’s through better monetization, smarter optimization, or proactive support when things don’t go as planned. We monitor the ecosystem constantly, often spotting issues before our partners even notice, and we fix them fast. Because that’s what being a true partner means.
In short: we don’t chase margin on both sides of the trade, we build value on one side, with clarity and integrity.
5. A Healthy Future Depends on Openness and Specialization
The most efficient and fair digital ad ecosystem is one built on open, interoperable platforms where each player has a clear role and incentive alignment.
This doesn’t mean innovation must slow down, far from it. But it does mean the industry should resist the temptation to centralize too much power in too few hands. Efficiency, trust, and performance thrive best when buyers have advocates, sellers have advocates, and systems are designed to keep those roles distinct.
True Efficiency Comes from Role Clarity
If there’s one lesson from the growing convergence in ad tech, it’s that you can’t serve every party equally, and trying to do so risks serving no one fully.
At ConnectAd, we believe in focus, independence, and a marketplace where power is distributed, not concentrated. Because in this business, as in any fair market, the more clearly you know who works for you, the better your outcomes will be.
