For too long, the focus has been heavily weighted towards demand-side technology, but the future of programmatic could lie in leveraging sell-side data and enriching the bid stream with smarter, more relevant signals, which can then be fed to the hungry buyside.

‍

Signals Are Evolving, Not Disappearing

‍

Let's be clear: the notion that signals are disappearing is a misconception. They are, in fact, evolving. We're moving beyond simple cookie-based identifiers to a richer, more nuanced landscape of contextual, behavioural, and environmental cues. Crucially, many of these powerful new signals are created directly by publishers. Think about:

‍

• Attention Signals: Real-time indicators of user engagement, moving beyond mere viewability to true cognitive presence – often generated from on-page interactions.
• Sustainability & Compliance Data: Not just consent signals, here we are looking at the overall 'compliance’ of the publisher and how sustainable the inventory is.
• ID-Less Insights: Probabilistic and aggregate data points that don't rely on individual identifiers but still inform targeting and measurement, frequently derived from a publisher's holistic understanding of their audience.

‍

The question isn’t about can we create these signals - they already exist, but we need to be asking how effectively we can capture, interpret, and integrate them into the programmatic pipes.

‍

This is where sell-side decisioning and bid enrichment become absolutely non-negotiable. They are the mechanisms by which these evolving signals – powered significantly by publisher first-party data – are attached to impressions, making them more valuable and targetable without relying on old methods.

‍

The Role of the Ecosystem: Relevance Through Enablement

‍

In this shifting landscape, the relevance of DSPs and SSPs hinges on their ability to embrace and enable this new signal flow.

‍

• SSPs must evolve into sophisticated decisioning engines, capable of ingesting diverse signals (attention, compliance, contextual, privacy-enhanced audience data from publishers) and enriching the bid request to deliver maximum value for publishers while meeting advertiser needs. They become the primary facilitators of inventory insight.
• DSPs must be ready to consume these richer, more intelligent bid requests, leveraging advanced algorithms to make smarter buying decisions based on evolving signals, rather than just traditional IDs.

‍

Crucially, this must be achieved without inflating Query Per Second (QPS) rates, but by making the bidding process more efficient and intelligent

Ultimately, publishers emerge as the guardians and originators of this valuable data. They own the direct relationship with the user, and their ability to ethically collect and expose these evolved signals, particularly through their robust first-party data, via sell-side platforms will define the future of premium inventory.

The Measurement Imperative: Why It All Fails Without It

‍

However, let's not sugarcoat it: without robust, verifiable measurement, all of this innovation is just theoretical. It's the Achilles' heel of any new ad tech solution. The challenge with measurement has always been its reliance on tech, which often creates its own silos and blind spots – especially when dealing with a fragmented environment like CTV or trying to understand cross-browser behaviour (yes I’m looking at you Safari!). Traditional media KPIs like CPC and LTA are not only inadequate for the Open Web, they are totally irrelevant for CTV, where brand lift and incremental sales are the real prize.

Anonymised: Solving the Measurement & Targeting Conundrum

‍

At Anonymised, we're tackling these fundamental challenges head-on. Our approach is built on enabling brands to connect their campaigns to tangible, sales-driven outcomes by addressing the core issues of reach and precise measurement in an ID-less world:

‍

• Future-Proof & ID-Less: Our entire stack is designed for an ID-less future. We don't rely on deprecated identifiers, ensuring campaigns are privacy-compliant, sustainable, and providing incremental value
• Omni-Channel Measurement: We've built proprietary measurement technology that works across all browsers, including Safari. This means we can provide a complete picture of campaign impact, delivering Safari-based attribution and enabling omnichannel incrementality – directly proving the uplift in sales from your CTV spend.

This is about more than just incremental improvements; it's about fundamentally transforming how digital campaigns are planned, executed, and measured. We're moving beyond the top-of-funnel narrative to deliver full-funnel, sales-connected performance.
