FromImpressions toInfluence:
Rethinking Measurement in the Age of AI
WE’RE LIVING THROUGH A MEDIA CORRECTION:

generative AI
Marketers and communicators have long chased attention through metrics that misled. And earned media specifically stayed tethered to inflated proxies through topline volume metrics. But GenAI is now forcing a reckoning. Not because it is changing the value of earned, but because it’s helping us bring a sharper focus to that value.
ThedeclineofUVMs: Acorrection, notacollapse
For years, impressions and Unique visitors per month (UVMs) stood as proxies for earned impact. Now, one ChatGPT prompt replaces multiple clicks.
In this new normal, UVMs may drop, but every visit

represents something deeper: intent, investment, and attention. And importantly, this isn’t a zero-sum game; the audience isn’t vanishing, it’s evolving, with growth showing up in new behaviors and platforms beyond publishers alone.
For marketers and communicators, this shift should prompt a recalibration of benchmarks. UVM drops are not failures; they’re the start of a more honest accounting.

Research from Evertune shows that over a third of top LLM responses draw on real-time web search across a wide range of sources. We know traditional journalism is an essential part of the mix, but it also brings in Reddit threads, YouTube videos, Indeed postings, ResearchGate papers, and GitHub snippets. In short: everyone is media now: influence can come from anywhere if it’s wellstructured, well-cited, and well-timed.
And what these LLMs influence in return is just as striking.

AI isn’t just reshaping information flows; It’s reshaping purchase journeys. For communicators, ignoring this shift doesn’t just mean missing out. It means fading out.
3 Makingmediadiscoverable tomachines
The relationship between humans and LLMs is dynamic: as we change how we ask, they change how they answer. This feedback loop is reshaping both search behavior and the media strategies needed to meet it.
Unlike traditional search, where visibility was tied to ranking and clicks, LLMs reorganize information based on user intent.
In testing query behavior and LLM responses, we’re seeing two clear patterns emerge:
1
Broad, awareness-focused queries that are about understanding big-picture information (e.g., “what’s a good skincare routine”) often stay contained within AI responses. Here, influence must become both mission and metric shaping how answers form, even when clicks don’t follow.
Deeper, more specific queries that move
2
toward decision-making (e.g., "best sunscreen for sensitive skin in humid weather") are more likely to push users to external sources but only if the content is visible, credible, and abundant. The bar on quality and quantity is higher than ever.
4 Earningyourwayin, throughculture
This much is clear: in the AI-shaped media network, influence is not paid, it’s earned.
You get surfaced because you’re the most relevant to the query, the moment, and the culture.
For marketers, this starts with carving out a clear role in culture; one that is:
• Repeatable in how it shows up,
• Valuable in what it contributes, and
• Intuitive to your brand and to the people it’s meant for

Anewmeasurementmandate:from impressions toinfluence
Theirony is thatwhile GenAI has disruptedtraditional metrics,ithas also given us thetools to replace them.Impressions andUVMs were nevergreatindicators of engagementorinfluence;they just happened tobeavailable atscale.
Now,we can dobetter.
The industry must stop asking, “How many saw it?” and start asking, “Did it land? Did it spread? Did it stick?”
And AI allows us to track cultural penetration, narrative uptake, and intent signals – markers that truly reflect attention.
In the end, this correction isn’t about loss; it’s about clarity. Impressions aren’t falling short as a metric because of AI they were falling short all along. AI just finally made it impossible to ignore.
