AI hasn’t killed the open web, but it has reprogrammed how people access information. In doing so, it has accelerated a long-awaited reckoning across the media value chain: the move from impression volume to signal density.
Generative answers are collapsing search journeys. Discovery is becoming compressed, fragmented, and increasingly off-domain. Meanwhile, advertisers are no longer just chasing reach. They are prioritizing environments where identity is real, attention is measurable, and outcomes are provable.
A clear pattern is emerging: monetization now favors infrastructure built on signal integrity, not surface exposure.
The post-click reality
AI Overviews and assistant-style answers are already reshaping search behavior. Entire categories such as finance, health, and how-to have seen traffic fall sharply, with publishers seeing as much as an 89% drop in click-through rates on previously high-volume pages.
These are not isolated algorithmic anomalies. This is systemic compression. Even with recent rollbacks by Google, fewer users are clicking out, and more are getting what they need from AI summaries embedded directly in search results.
For publishers, the implication is clear: the destination model is eroding. For platforms that monetize on top of publisher inventory, this fragmentation introduces volatility into everything from impression availability to match-rate consistency.
Two publisher strategies in an AI-shaped landscape
Faced with shrinking search-driven traffic, publishers are dividing into two broad camps.
Some are choosing to syndicate. They are licensing content directly into AI models and assistants, striking deals with providers such as OpenAI and Google in exchange for access to archives, live feeds, and structured metadata. These partnerships often include revenue sharing, query-level metering, and linkbacks. It is still early, but it signals a shift in how media companies assign value to their content – not by page views, but by structured utility.
Some major examples include:
- Axel Springer x OpenAI (2023)
- Reddit x Google (2024)
- Stack Overflow x OpenAI (2024)
Others are focusing on control. They are doubling down on owned surfaces, particularly apps and CTV platforms, where they command the entire experience from user session to monetization logic. These environments offer persistent identity, cleaner signals, and more granular telemetry. For many, this is not about abandoning the web. It is about reallocating attention toward surfaces they can measure, curate, and scale on their own terms.
How advertisers are adapting to signal over scale
Advertisers are moving fast toward environments where signal depth drives performance.
The shift is clear across several high-growth channels:
- CTV, where device graphs and ACR data enable precise targeting with brand-safe scale
- Retail media, expected to exceed $200 billion globally by 2026, with built-in closed-loop attribution
- Mobile in-app, which, in the U.S., accounts for more than 80% of mobile time and delivers:
- Deterministic identifiers (device ID, login)
- Immersive formats with high engagement
- OM SDK support for verified viewability and fraud protection
Buyers are not just demanding viewability. They are optimizing for attention, filtered by dwell time, scroll depth, and verified engagement. They want cleaner paths, fewer hops, and reduced media waste. And they want to activate identity where it is available, not approximate it through increasingly brittle signal chains.
The result is a shift away from the open web’s patchwork of inferred relevance toward structured, signal-dense surfaces that support predictable delivery and measurable lift.
Why app environments are leading the signal economy
App-based publishers, especially in verticals such as gaming, utilities, weather, and messaging, are proving far more resilient to the AI-driven collapse in organic discovery.
Their audiences arrive directly. Sessions are habitual. The data emitted per session (device ID, session length, ad interaction, engagement flow) is deeper and more actionable than what can be captured through browser-based traffic.
Through SDK-level enrichment and OM SDK compliance, these publishers are enabling higher bid density, stronger match rates, and more competitive pricing. They are also packaging inventory not only by app ID but by verified user attention, with PMPs built around viewability, engagement thresholds, and session context.
In short, app supply is not just brand-safe. It is signal-optimized.
Rethinking media infrastructure for performance and precision
Across the ecosystem, there is a clear shift from broad reach to qualified, high-utility impressions.
For publishers, this means investing in AI-driven personalization engines, segment-based paywalling, and clean-room strategies that activate first-party data without relying on third-party cookies.
It also means refining monetization infrastructure, optimizing supply paths, reducing QPS and energy use, and rethinking how value is packaged and priced. Sustainability is no longer a CSR line item; it is becoming a performance signal.
Meanwhile, demand platforms are evolving in parallel. The smartest DSPs are designing deal logic around measurable attention, building filters for signal-rich supply, and partnering with inventory sources that offer activation-ready identity and clear paths to ROI.
This is less about disruption and more about calibration; aligning tech stacks, measurement layers, and buying strategies around signal fidelity instead of raw volume.
The real reset: from clicks to substance
The AI shift is not a bump in the road. It is a reset in how value is generated and captured across the media landscape.
The platforms and partners positioned to win in this new economy are those that:
- Prioritize high-signal environments such as apps, CTV, and commerce surfaces
- Build and curate identity-resilient supply that works post-cookie
- Optimize packaging around verified attention, not just frequency
- Maintain transparent, performant supply paths that reduce waste and duplication
This is not about weathering the end of search. It is about designing for a media economy where signal-rich formats outperform everything else.
When discovery is fragmented, infrastructure is what creates leverage.
And when attention is finite, quality wins.
