Measuring the impact of Generative Engine Optimization is not as hard as you might think

Since launching our Generative Engine Optimization (GEO) service, one thing has become clear: people are still unsure about measurement. Specifically, there’s a narrative circulating among some comms professionals that measuring visibility in Generative AI tools is either impossible or, at best, unreliable.

Let’s be honest: that’s nonsense.

Measurement is possible. It’s already happening. And it doesn’t require building a mystery box of proprietary dashboards to make it work.

GEO isn’t magic; it’s just search, evolving

GEO is a new name, yes. But at its core, it’s about visibility in discovery. Just like Search Engine Optimization (SEO), it relies on clear signals: structured content, trusted sources, and brand authority. And like SEO, it can be tracked.

There are now industry-standard tools: from long-established players like SEMrush Enterprise’s AI Optimization suite to newer entrants focused specifically on AI insights, such as Evertune AI. This graphic from a16z alone shows how many services are available and how misguided the “measurement isn’t possible” narrative really is.

These tools can show how often your brand is cited across GenAI platforms like ChatGPT, Perplexity, and Google’s AI Overviews. With this toolkit, you can track where, how, and in what tone your brand appears. You can see which content is influencing results, the key messages, keywords, and questions involved. You can benchmark against competitors.

We do this every day. So, when PRs claim it can’t be measured, what they usually mean is they haven’t looked for the solutions, or haven’t worked out how to use them effectively.

Beware the self-made black box

More concerning is the rise of proprietary “GEO measurement platforms”: in-house tools that are rarely peer-reviewed and often vague on methodology. We’ve seen this story before: give your client a dashboard, brand it well, and hope they don’t ask how it actually works. In a discipline already grappling with trust and transparency, this is the last thing PR needs.

If your measurement system can’t be replicated, can’t be interrogated, and doesn’t align with established search metrics, then it isn’t measurement. It’s theatre.

The tools exist. The data is there. The challenge is understanding it.

Our Fusion team isn’t building black boxes at Fire on the Hill. We’re building strategies based on real tools and real data. We track AI visibility across multiple platforms, measure which sources are being cited—Wikipedia, analyst reports, blogs—and continuously adapt based on what’s working. This is marketing science, not magic.

Of course, GenAI behavior is inconsistent. Of course, results vary by prompt. But that’s no excuse to shrug and say, “you can’t measure this”. If anything, it’s a reason to double down on rigor, combine multiple tools for greater assurance, and stop hiding behind uncertainty.

So, what should PRs do?

Stop saying GEO measurement isn’t possible. It is. Stop pretending proprietary dashboards equal credibility. They don’t. And stop seeing this as someone else’s problem. If PR wants to lead in this space (and it absolutely should, since coverage and content remain king), then we need to approach GenAI the way we’ve approached media for decades: with clarity, credibility, and a commitment to being the trusted voice in the room.
