how publishers make money in 2025 in an ai fused world

as AI and privacy shake things up…. a seasoned ad-ops engineer tells the story over a coffee:

The infrastructure in plain sight

Let’s start by pulling back the curtains on the “ad tech stack” so we understand what the theatre looks like before we talk about who’s getting paid and how.

Here are the core layers that keep a publisher’s ad-engine running:

1. Supply side / Publisher layer

This is you, the publisher: you’ve got a site or app, you’ve got inventory (pages, video slots, in-app placements). You need to make that inventory available to the world beyond your “direct deals.” That’s what a Supply‑Side Platform (SSP) handles: it lets you set floors, connect to exchanges, manage yield.

2. Intermediary layer (exchanges, header-bidding)

Once the inventory is up for sale, you need competition. That’s where auctions and exchanges come in. For example, the technique of Header Bidding lets a publisher send their inventory to many demand partners simultaneously so you don’t leave money on the table.

You’ll also see ad exchanges, demand-side platforms (DSPs) and networks all doing their thing to match buyer and seller in real time.

3. Data / Identity / Targeting layer

To make inventory more valuable you need good audience data or context. With cookies dying and privacy rising, publishers who can use first-party data or contextual signals have an edge.

4. Creative / format / device layer

Inventory isn’t just a banner on a desktop. You’ve got mobile, in-app, connected TV (CTV), video, native, commerce-ads. Each format commands different CPMs and buyer appetites. For publishers, playing the format game matters.

What’s changed (and still changing)

Okay, so you know the layers. Now let’s talk about what’s new and what threatens margins—and what publishers are doing about it.

AI, the phantom in the ad tech room

Artificial intelligence is racing through the stack. Buyers want smarter bidding, better context, faster optimization. Publishers who lean into AI tools for yield optimization, dynamic ad placement, smarter formats are seeing benefits. For example: “AI-Powered Optimization” shows up as a key trend for 2025.

Also, new ad formats are emerging around AI-driven experiences (like chat-based or voice-based contexts) so publishers can sell novel inventory.

Privacy & identity headwinds

Tracking is under siege. Studies show that when user tracking falls, ad impression prices for publishers drop. (Yes, the joke: you’re paid less because you know less about the user).

Privacy regimes (GDPR, CCPA) and cookieless changes force publishers to rethink: more context, less third-party data. The burden of proving quality inventory has increased.

Format & channel fragmentation

Users aren’t just on websites anymore. They’re on mobile apps, streaming via CTV, interacting with embedded video, even AI-chat-interfaces. Publishers who only focus on “desktop display” are missing big pieces of the pie. For example, programmatic spending is shifting heavily toward connected TV and private marketplaces.

Consolidation and yield pressure

More tech vendors, more vertical integration, bigger platforms absorbing smaller ones. That means for a smaller publisher the “take” from the supply chain might shrink unless you control your stack. Also auction dynamics: more competition, sometimes lower floor yields if you’re not optimized.

How publishers are still

making money

Despite all the turbulence, publishers are not bankrupt—they’re adapting. Here’s what’s working.

A. Own your data and audience

Publishers who understand their audiences (first-party data) can:

Demand higher CPMs because their inventory is more predictable and targeted.
Use contextual signals when identity is weak (good for privacy-first). If you treat your users as an asset—not just “traffic”-you’re ahead.

B. Diversify across formats and devices

A site with display banners alone is vulnerable. But if you also monetize:

Video (pre-roll, mid-roll)
CTV inventory
Native content-recommendation units You expand revenue streams and reduce dependency on any one format.

C. Private marketplaces & direct deals

Rather than open auctions where your inventory gets commoditized, publishers are building private deals: select advertisers, premium placements, better control. For example: programmatic direct and private marketplaces account for a big share of ad spend.

D. Commerce, affiliation, and non-traditional revenue

Beyond straight ad impressions: publishers are earning via affiliate links, commerce references, even data licensing. Example: a major ecommerce platform is testing paying publishers for traffic, not just for sales.

E. Focus on yield, not just fill

It’s not enough to fill ad slots. Publishers must optimize yield (CPM, eCPM), reduce latency, avoid bad inventory, ensure viewability, fight fraud. These operations cost but they pay. Monitoring performance, trimming under-performing placements, moving to higher quality demand—all matter.

The “stack” in action (a quick metaphor)

Imagine your site is a fruit stand. The layers above are: you grow the fruit (content + audience), you invite many buyers (ad exchanges/SSPs), you label the fruit (data/context), you package it in different ways (video, mobile, native). If any layer is weak—bad fruit, few buyers, no label, weak packaging—you don’t get paid much.

Now throw in: a rainstorm of AI (changing demand), laws blocking some buyers (privacy rules), a new aisle (CTV) you hadn’t stocked. If you’re not agile you get stuck with last year’s apples.

What to keep an eye on if you’re a publisher (or building for publishers)

Do you have access to first-party audience signals? Are you building that asset?
Are you tracking yield across formats/devices? Are you still stuck on desktop display?
Are you optimising your stack (header bidding, SSPs, direct deals) or just hoping “it works”?
Are you aligning your strategy with privacy shifts (cookieless, contextual)?
Can you experiment with new formats—video, CTV, commerce-driven, interactive?
Are you keeping tech costs in check (too many vendors eat margin) and focusing on Those things you can control?

Final thought

Yes, the ad tech world is messy right now. AI, privacy, device shifts—they all threaten the playbook. But for publishers who treat themselves as media businesses (not ad inventory factories), who optimise yield, diversify formats, leverage first-party data, the opportunity remains very real.

If you’re building a product (or have a site) that depends on ad revenue: focus less on “get another ad network plug-in” and more on “how do I push the stack from good to great”. Because the layers are still there. It’s how you stack them that determines if you make money—or just make noise.
