What’s curation in AdTech?

Programmatic media buying isn’t getting any easier.

Buyers face rising signal loss, shrinking margins, and growing pressure to perform in a privacy-first world. Add in fragmented tech, shifting privacy regulations, and inconsistent identity signals, and reaching the right audience at scale has never been more complex (or costly).

Meanwhile, advertisers demand more transparency, publishers want control, and consumers expect relevance without feeling watched. Open exchanges, legacy data management platforms (DMPs), and spray-and-pray strategies just aren’t cutting it.

That’s why curation has become a trending topic in the AdTech space. In programmatic advertising, curation refers to the strategic integration of enriched data and quality inventory into a single package — often executed as a private marketplace (PMP) deal. This approach reshapes how campaigns are built, activated, and optimized by enabling performance-ready buys that reduce waste, increase relevance, and give marketers greater control over outcomes.

It’s no wonder then that curation investments are accelerating, PMPs are gaining traction, and buyers are shifting budgets accordingly. Over 66% of the $150 billion+ open exchange programmatic market now flows through curated PMPs, with industry giants like Google publicly backing curation as a core strategy.

So what exactly is programmatic curation, and why is it becoming essential for privacy-conscious, performance-driven marketers? Let’s break it down.

What does programmatic curation mean in AdTech?

Programmatic curation is the process of filtering, structuring, and packaging enriched data with high-quality programmatic inventory — enhanced by real-time optimization to create more targeted, efficient, and transparent media buys. Instead of buying at scale and hoping for the best, curation prioritizes accuracy and value over volume, resulting in more targeted, efficient, and transparent media buys.

As privacy regulations reshape targeting, curation is becoming a key differentiator in an increasingly crowded AdTech space. It connects robust data with quality supply, helping marketers stay effective while giving publishers new ways to monetize with control.

But not all curation is created equal. Programmatic curation requires three core elements:

1. Unique data

Unique, privacy-compliant, and valuable.

2. Strong supply connections

Access to quality inventory from publishers at scale.

3. Optimization tools

To measure, refine, and improve performance during a campaign and improve performance throughout the campaign lifecycle.

Without all of these elements, a so-called “curator” may simply be repackaging inventory without delivering the full value of a curated approach.

Why does curation still matter with cookies sticking around?

While third-party cookies and mobile IDs like IDFA haven’t gone away, the industry has already pivoted in anticipation of their decline.

Even without Google flipping the switch, signal loss is here thanks to Apple’s ATT, tighter compliance rules, and new tracking restrictions. Marketers are dealing with less data, more fragmentation, and fewer reliable IDs. So if you want to run an effective, scalable media campaign today, you need tools that go beyond third-party cookies.

That’s why programmatic curation is gaining ground as a better, more sustainable way to buy media. Investments in programmatic curation are growing, and not just for identity resolution. Marketers are leaning in because it:

• Combines verified audience data with premium inventory
• Supports ID-free or context-aware targeting
• Enables scalable, identity-agnostic strategies
• Improves data quality through enrichment
• Creates more controlled, pre-approved media paths via PMPs

Experts anticipate that, at some point, publishers will have to lean into this method.

“Curation will be bigger than header bidding and as big as programmatic or RTB — that’s our bet.”

Whether cookies stay or go in the future, curation works for an ecosystem that demands smarter, cleaner, and adaptable media buying.

What are the benefits of curation and who wins?

Curation is one of the few innovations in AdTech delivering meaningful wins across the ecosystem. By bringing better data, cleaner supply, and more intentional targeting into programmatic advertising, it helps brands, agencies, and media buyers drive stronger performance, gives publishers more control, and creates a more respectful experience for consumers.

And unlike traditional approaches, curation is built for what’s now and what’s next. Here’s how each group benefits and why it matters.

Brands and agencies

Curation helps brands and agencies run smarter, more efficient campaigns by connecting high-quality data with premium supply. It delivers:

• More efficient supply paths with less waste and better performance
• Lower costs than DMP segments and open exchange buys
• Cleaner, pre-vetted inventory that aligns with audience and brand goals
• Future-proofed buying via cookieless and log-level data integrations
• Stronger targeting and measurement driven by enriched data and actual usage signals instead of modeled assumptions
• Better outcomes through real-time supply and data optimization

Publishers

For publishers, curation makes inventory more addressable without giving up control. It enables:

• Smarter packaging that aligns with buyer needs and campaign goals
• Higher CPMs by curating inventory above open exchange floors
• More control over how audiences are accessed and how inventory is monetized
• Access to higher-value demand through curated, data-backed deals
• Better protection of proprietary audience in a privacy-conscious environment

Consumers

At the end of the chain, curation improves the ad experience for those who matter most: your audience. It supports:

• Higher-quality content alignment for more natural, less disruptive ad experiences tailored to their interests
• Less invasive tracking, as targeting becomes more data-smart and privacy-aware, with reduced reliance on legacy identifiers and personally identifiable information (PII).

Curation is setting a new standard for how data, inventory, and experience come together across the ad ecosystem. When media is smarter, cleaner, and more intentional, everyone wins.
