Someone in Prosper asks ChatGPT, "Who is a good plumber near me?" They don't get ten blue links. They get a short paragraph with three or four company names and a line about each. If yours isn't one of them, you were never in the running. Answer engine optimization (AEO) is the practice of making a business easy for AI answer tools such as ChatGPT, Perplexity and Google's AI Overviews to find, understand and name when someone asks a question that business can answer.
It's a new name for work that overlaps with search engine optimization (SEO) but aims at a different target. SEO gets you a spot on a results page. AEO gets you into the answer itself. This post explains the difference, why it matters for a local business, and the three things that decide whether you get named. If you already know what AEO is and want the specific site changes, read our post on how to show up in AI search answers.
How is an AI answer different from a search results page?
A search results page is a list. Google ranks ten or so pages, you scan them, you click one. Being eighth still gets you some clicks. Being on page two gets you almost none, but at least you exist.
An AI answer is a paragraph. The engine takes the question, runs its own web search behind the scenes, reads a handful of pages it trusts, and writes a reply. For a "who should I call" question, that reply typically names three to five businesses. There is no page two. You're either named or you're not.
The engine also isn't reading your whole site. It pulls sentences. If your home page says "Solutions for the modern homeowner" and a competitor's says "We repair and replace water heaters in Collin County," the engine knows what to do with one of those and not the other.
Is AEO just SEO with a new name?
Partly. Both need a site that crawlers can reach, pages that say something specific, and listings that agree with each other. If your SEO is in good shape, you're most of the way there. The differences are in what gets measured and what gets rewarded:
- SEO measures positions and clicks. AEO measures mentions: how often you're named in an answer.
- SEO rewards many pages built around search terms. AEO rewards a few pages with direct, quotable answers.
- SEO brings people to your site. AEO often gets you named without a click, so your name, city and phone number need to be in the answer, not only on your site.
A sensible plan treats AEO as a layer on top of basic SEO, not a replacement for it.
Why should a local business care about answer engine optimization?
Because the person asking gets names, not links. They can't scroll past the answer to find you. If the engine doesn't name you, you didn't lose the comparison. You weren't in it.
We won't guess at how many people now ask an AI tool instead of Google, because we don't have a trustworthy number. What we can share is what we measured. When we ran 120 questions through three AI engines (OpenAI, Perplexity and Google's Gemini) for Frisco, Celina and Prosper businesses looking for help with AI assistants, websites and automation, here is what came back:
- 90 of the 120 answers were city questions, such as "who builds websites for a business in [town]." Our own company was named in 0 of those 90. We had the service pages but not the city pages, and the engines had no reason to connect us to those towns.
- Only two businesses were named by all three engines more than twice. Most names showed up in one engine's answers and not the others, because each engine has its own favorite sources.
- Gemini cited business websites 340 times and directories 4 times. Perplexity cited LinkedIn company pages 25 times.
- 4 of the 120 answers named nobody at all.
Two lessons. First, for most engines, your own website is the whole case. A page that says "we do this, in this town" is what gets quoted. Second, visibility is earned per engine, so a check that only looks at one tool tells you less than it seems to.
The three things that get a business named
1. A website that says what you do and where, in sentences an engine can quote
Your home page should contain one plain sentence that states your service and your service area: "We install and service residential HVAC systems in Collin and Denton counties." Not in an image, not in a slogan, in text. Each service page should open with a direct answer to the question its title asks. If you use a term your customers ask about, define it once in a clean sentence, because definitions are exactly what engines lift. A short FAQ with real customer questions, answered in the first sentence of each reply, does more than a page of adjectives.
2. Consistent listings and reviews
Engines check whether the rest of the web agrees with your site. That means a Google Business Profile with the right categories, hours and service area, plus Bing Places, Apple Business Connect, Yelp and the directories for your trade, all showing the same name, address and phone number. Reviews matter too: engines read them and sometimes quote them, so a steady flow of honest reviews that mention the service and the town helps. In our scan, Perplexity leaned on directory and LinkedIn pages in a way the other two engines barely did, which is one more reason to keep listings current.
3. Structured data and a machine-readable summary
Structured data is a set of labels, written in a standard called Schema.org, that marks up facts on your pages so a program can read your business name, address, hours and services without guessing. Google documents it in its Search Central guides. On top of that, a small text file at yoursite.com/llms.txt gives AI crawlers a plain summary of who you are, what you do and where. Not every engine reads it yet, but it costs almost nothing and gives the ones that do a clean source.
A five-question self-check you can do in ten minutes
- Open ChatGPT or Perplexity and ask, "Who is a good [your service] in [your town]?" Are you named? Who is?
- Ask the same tool, "What does [your business name] do?" Is the answer correct? A wrong answer usually means the engine is blending you with a similarly named company or reading an old page.
- Open your home page on your phone. Without scrolling, can you find one sentence that says what you do and where? Would it make sense copied on its own?
- Search your business name on Google Maps, Bing and Apple Maps. Do all three show the same name, phone, address and hours?
- Type yoursite.com/llms.txt into a browser. Does anything load?
One honest warning: AI answers change from day to day, sometimes from one ask to the next. A single run tells you little. Ask the same ten questions once a month, count how many times you're named, and watch the count. Anyone promising you a guaranteed spot is promising something they don't control.
An AI answer names a handful of businesses, so the goal is to be one of them, and the only honest measure is how often that happens.
