AI Changed Customer Discovery. We're Still Figuring Out How to Measure It.

What I learned after going deep on how Google, ChatGPT and other AI systems are changing the way customers find businesses.

In short: AI didn't create another marketing channel; it added a technical layer to how customers discover businesses, so start by finding out where your customers actually begin discovery, and treat any single, precise-looking AI visibility score with caution until you know exactly what it measures.

Slide 1 of 10: AI didn't create another marketing channel. It changed the customer discovery system. What business leaders need to know now. Slide 2 of 10: Start with the customer, not "GEO." Before you measure AI visibility, ask where your ideal customer actually begins discovery: Google-first (Search, local and AI experiences) or LLM-first (ChatGPT or another LLM). Slide 3 of 10: Where they start changes what you should measure. Google-first: understand Search, local results, AI Overviews and AI Mode. LLM-first: start with the LLMs your ICP actually uses. Don't track 10 platforms just because a dashboard can. Slide 4 of 10: Even "Google AI" isn't one thing. Customers can encounter traditional search, local results, AI Overviews, AI Mode and Gemini, each a different way a business may surface. Slide 5 of 10: Mentioned does not equal recommended. Being mentioned means appearing in the answer; being recommended means being presented as a choice. Those are different observations and should be measured differently. Slide 6 of 10: Then the testing gets messy. AI results can vary by geography or market, query wording, session and personalization, repeated runs, source selection, and platform or model, which makes simplistic rank tracking a poor mental model. Slide 7 of 10: What exactly is a "43/100 GEO score"? Before you trust a precise-looking AEO/GEO score, ask: 43 out of what, which system, which queries, which market, which customer, and what testing conditions. Slide 8 of 10: This is bigger than SEO plus a new acronym. AI visibility spans customer behavior, LLM behavior, search and local signals, sources and citations, website architecture, and structured data. Slide 9 of 10: AI may narrow the list. Humans still do the due diligence. After AI discovers, researches and compares to produce a shortlist, people validate through a website, reviews, credentials and contact. Slide 10 of 10: Businesses now have to win twice. Machine discovery: be understandable, credible and findable. Human validation: be trustworthy, relevant and compelling.

Swipe through the 10-slide version. The full written version is below.

Is AI visibility just another marketing channel?

I've spent a ridiculous number of hours recently researching and testing how businesses are actually being discovered and recommended across Google, ChatGPT and other AI systems.

I started with what seemed like a simple question: how do you determine whether a business is well positioned to be discovered and recommended by AI? It got complicated fast.

The biggest thing I've taken away from the exercise is that we may be framing this incorrectly. AI didn't simply create another marketing channel. It added a new technical layer to the customer discovery system.

Where does your customer actually begin discovery?

Before businesses start worrying about AEO scores, GEO scores or optimizing for every LLM under the sun, there's a much more fundamental question to answer: does your customer start with Google, with ChatGPT, or somewhere else? Start with where your customers actually begin their search, not with the latest AI marketing acronym.

That answer changes what you should measure. If your ideal customer is Google-first, you need to understand Search, local results, AI Overviews and AI Mode. If they're LLM-first, start with the LLMs your ideal customer actually uses. Either way, don't track ten platforms just because a dashboard can. Choose the system based on the customer, not the acronym.

And even “Google AI” isn't one thing. Inside a single ecosystem, a customer can run into traditional search, local results, AI Overviews, AI Mode or Gemini. Different experiences, different behaviors, and different ways a business may surface.

Why is AI visibility so hard to measure?

From there, things get considerably more technical. Different platforms behave differently, and there's a lot more complexity than a single “AI visibility score” suggests.

Start with this: being mentioned isn't the same as being recommended. A business can appear in an AI answer without being meaningfully recommended. Appearing in the answer and being presented as a choice are different observations, and they should be measured differently.

Then the testing itself gets messy. AI results can vary based on geography or market, query wording, session and personalization, repeated runs, source selection, and platform or model. That makes simplistic “rank tracking” a poor mental model. Measurement requires a disciplined, transparent testing method.

What should you ask before trusting an AI visibility score?

Some of the very precise-looking measurements being sold today deserve a few more questions about what, exactly, they measure. Picture a “43/100 GEO score.” Before you trust a number like that, ask:

  • ✓

    43 out of what?

  • ✓

    Which system?

  • ✓

    Which queries?

  • ✓

    Which market?

  • ✓

    Which customer?

  • ✓

    What testing conditions?

If the methodology isn't clear, the precision may not mean much.

Is this just SEO with a new acronym?

No, the real challenge is bigger than SEO. AI visibility touches customer behavior, LLM behavior, search and local signals, sources and citations, website architecture and structured data. It's a cross-functional discovery-system problem, which is why chasing a single score or a single tool usually misses the point. It's the same instinct behind figuring out whether a problem is technology, process, or AI before spending money on a fix: understand the system first.

Why do businesses now have to win twice?

AI may narrow the list, but humans still do the due diligence. AI discovers, researches and compares businesses and produces a shortlist. Then a person checks your website, your reviews, your credentials and how to contact you.

So businesses have to work for both machine discovery and human validation. For machines, that means being understandable, credible and findable. For people, it means being trustworthy, relevant and compelling. For high-value purchases, the machine and the human both matter.

The machine side is what my Local AI Visibility work focuses on: giving AI systems clear, consistent, credible evidence about who you are and what you do. The human side is everything a prospect finds once they click.

My biggest takeaway? We're still early. There are absolutely things businesses can do now to improve how they're discovered and understood by AI. But I think we should be very careful about pretending this ecosystem is more settled, predictable or measurable than it actually is.

The takeaways, in short

  • AI didn't create another marketing channel; it added a technical layer to the customer discovery system
  • Start with where your ideal customer actually begins discovery, then choose what to measure
  • “Google AI” is several different experiences: search, local results, AI Overviews, AI Mode and Gemini
  • Being mentioned in an AI answer isn't the same as being recommended
  • Results vary by market, query wording, personalization, repeated runs, sources and platform, so simple rank tracking is a poor model
  • Ask what a precise-looking score actually measures, and how it was tested
  • Businesses have to win twice: machine discovery and human validation

Questions we hear about this.

Should I pay for an AI visibility (AEO or GEO) score?

Not until you can say what the number actually measures. Ask what it's out of, which AI system and queries were tested, which market and customer it reflects, and under what testing conditions. If the methodology isn't clear, the precision may not mean much.

Which AI platforms should I track?

Start with where your ideal customer actually begins discovery. If they're Google-first, understand Search, local results, AI Overviews and AI Mode. If they're LLM-first, start with the LLMs your ideal customer actually uses. Don't track ten platforms just because a dashboard can.

Is being mentioned by AI the same as being recommended?

No. A business can appear in an AI answer without being meaningfully recommended. Appearing in the answer and being presented as a choice are different observations, and they should be measured differently.

For business owners, the goal isn't to chase the newest acronym. It's to understand how your customers are finding you now, and make sure you're positioned to be found as that behavior changes.
