What AI Actually Cites: New Data Is Changing the Role of PR

/

Recently, I reviewed new research on how AI platforms source and cite information and the findings challenge many assumptions about visibility.

Studies like Muck Rack’s Generative Pulse report and Code Red and Merritt Group’s research on PR in the LLM era show that the way companies are discovered is shifting in meaningful ways. For PR and marketing teams, this has real implications for where to focus and how to think about influence.

Earned media is still the foundation

One of the most important takeaways is that AI systems overwhelmingly rely on non-paid, third-party content.

Research shows that approximately 82% of links cited by AI come from earned media, with journalism alone accounting for roughly a quarter of all citations.

This reinforces something PR professionals have long understood: credibility comes from independent sources.

What’s changed is that this credibility now directly shapes how AI systems describe companies and technologies.

Fresh content has outsized impact

Timing also plays a bigger role than many expect.

More than half of AI citations come from content published within the past year, with the highest concentration occurring within the first week of publication.

This suggests that visibility is not just about building a long-term presence. It also requires a consistent flow of timely, relevant coverage.

For companies, this means a steady cadence of announcements, commentary, and thought leadership is more important than ever.

Not all media is equal

Another key insight is that AI systems do not treat all sources the same.

Research from Code Red and Merritt Group shows that specialist cybersecurity publications often carry more influence than major national media outlets when it comes to technical topics.

This reflects how AI systems prioritize:

  • Technical precision

  • Consistent terminology

  • Clear, structured explanations

For cybersecurity companies, this is a critical shift. Coverage in the right outlets can matter more than coverage in the biggest ones.

The journalists AI relies on may surprise you

One of the more striking findings is the disconnect between traditional PR practices and AI-driven visibility.

Data shows that the journalists most cited by AI have only about a 2% overlap with those most frequently pitched by PR teams.

This suggests that many PR programs are optimized for relationships and reach, but not necessarily for influence within AI systems.

As a result, companies may be missing opportunities to shape how they are represented in AI-generated answers.

Consistency and clarity shape AI representation

Beyond where content appears, how it is written also matters.

The Code Red research highlights the importance of semantic stability which means using precise, consistent language to define concepts.

Content that clearly explains:

  • What a technology does

  • How it works

  • Where it applies

is more likely to be reused and synthesized by AI systems.

By contrast, vague or overly promotional messaging is less likely to be retained.

The role of PR is expanding

Taken together, these findings point to a broader shift.

PR is no longer just about generating awareness or securing coverage. It is about shaping the information layer that AI systems use to generate answers.

That includes:

  • Securing coverage in credible, relevant outlets

  • Maintaining consistent messaging across channels

  • Producing content that is clear, structured, and reusable

In this environment, PR is not just influencing perception. It is influencing how companies are represented at the point of discovery.

The bottom line

AI is not replacing traditional media. It is amplifying the importance of it.

The companies that show up in AI-generated answers are the ones that consistently appear in credible sources, communicate clearly, and stay visible over time.

For organizations looking to compete in this new landscape, PR is not optional. It is foundational.
