What is AI search optimization (AIEO)?

The question moved

An owner gets a call from a new customer and asks the usual question: how did you hear about us? The answer used to be Google, a referral or a truck on the road. More and more often now it is something else. "I asked ChatGPT who to call, and it said you."

That sentence describes a real change in how buyers choose. A buyer who used to type a few words into Google and click through a page of results now types the whole question into an AI assistant: who is the best company for this job, near me, that does it right? The assistant does not hand back ten links. It hands back a name or two, often with a reason. The buyer calls the name.

AI search optimization is the work of being that name.

What AIEO means

AIEO stands for AI engine optimization. Depending on who is talking, it is also called GEO (generative engine optimization), AEO (answer engine optimization), LLM optimization or AI search optimization. The labels differ. The goal is the same: when a buyer asks an AI assistant who to hire for your kind of work, in your market, your business is the one it recommends.

The engines that matter today are ChatGPT, Gemini, Claude, Perplexity and Grok, plus Microsoft Copilot and the AI answers that now sit at the top of many Google searches. Buyers spread across all of them, and each one forms its own view of who is worth recommending. Being named by one and missing from the others leaves calls on the table.

How it differs from SEO

Traditional search optimization earns a position in a ranked list. The buyer still reads the list, compares, and picks. Position three on page one still gets clicks.

An AI answer works differently. The assistant has already done the comparing. It reads what it can find about the businesses that do this work, weighs it, and names one or two. There is no position three. Either you are in the answer or the buyer never hears your name.

That is why a business can rank well on Google and still be missing from AI answers, and why the reverse also happens. The two share a foundation: pages the engines can reach, written clearly, with facts that agree with each other. But the target is different. SEO asks where you rank. AIEO asks whether the engine names you, and what it says when it does.

They also reinforce each other. At WERCS Inc., a company whose website our team built and runs, both rose together after the new site launched. Google Search Console clicks went from 19 in February 2026, the first month the property reports, to 617 in September 2026. Since launch, AI assistants have sent at least 244 visitors: 191 from ChatGPT, 33 from Gemini, 11 from Perplexity, 5 from OpenAI and 4 from Copilot (Google Analytics, first-visit source, through October 18, 2026).

What the engines need to recommend you

An AI assistant recommends a business when three things are true.

It can find you. Your pages are public, reachable by the engines' crawlers, and say what you do in plain words. OpenAI, for example, publishes separate crawlers for search and for training, and a site can welcome one without the other. A business that blocks the crawlers, or hides its services behind forms and images, gives the engine nothing to read.

It understands you. The engine knows exactly what you do, for whom and where. A page that says "quality solutions for all your needs" tells it nothing. A page that answers the question a buyer actually asks, in that buyer's words, tells it everything. The same goes for the facts about you elsewhere on the web: your name, location, services and phone number should match everywhere they appear.

It trusts you. The engine checks what you say against what others say. Real reviews, real work shown, clear facts that agree across sources and a site that has answered buyers' questions well over time all count. Claims with nothing behind them do not.

Google says plainly that a page needs to be indexed and eligible for regular search to appear in its AI features, and that no special file or special markup is required. There is no trick. There is a business made easy to find, easy to understand and easy to trust.

Why timing matters in your niche

Every niche has a first business the engines can trust. In a niche where nobody is doing this work yet, the engines have little to go on, and the first business that gives them clear, trustworthy answers becomes the name they repeat. Later arrivals are competing against an answer that already exists.

That is why we take one business per niche per market. If we worked for two competitors in the same place, we would be working against ourselves.

How to tell whether it is working

Website analytics catch only part of it. When an assistant names your business, some buyers click through and show up as a visit from ChatGPT, Gemini or Perplexity. Many more just call. Customers regularly call WERCS and say ChatGPT told them WERCS was the best choice. Those calls never appear in website analytics, because a buyer who hears a name from an AI assistant often just picks up the phone, so every AI number here is a minimum.

So measure it three ways:

1. Ask the engines. Put the same buyer questions to each assistant every month and record who it names, dated.
2. Watch the visits. Analytics tools record visits that arrive from AI assistants. Track them by month.
3. Ask every new caller. "How did you hear about us?" is still the best question in marketing. Write down every answer that names an AI assistant.
