First: what "AI visibility" means
AI visibility is whether — and how often — AI assistants recommend your business when someone asks for what you sell. Traditional SEO asks: "Do I rank on Google?" AI visibility — also called answer engine optimization (AEO) and generative engine optimization (GEO) — asks: "When a homeowner asks ChatGPT who to call for AC repair, does it mention me?"
It's a different game with different rules. Google ranks pages; AI assistants synthesize answers. Google rewards keywords; AI assistants reward clear, citable, trustworthy information. A page-one Google ranking does not guarantee a ChatGPT mention.
How we ran the test
Thirty-five questions — the kind your customers ask about you every day. For an HVAC company, that sounds like: "my AC stopped blowing cold air, what should I do," "what are the best HVAC companies in Orlando," "how much does a new AC unit cost in Florida." (We ran our test in our own industry — AI services for local businesses — but the question pattern is identical.) Each asked in a brand-new conversation (no context carried over), default search mode, and for each answer we recorded who was mentioned, who was recommended, and which sources were cited. No brand names in the questions — we wanted the assistant's genuine shortlist.
The pattern: who gets recommended
In every category we tested, the same shape appeared. Nearly every answer drew from a small set of established names:
A handful of established names won nearly every question in their category — including one niche-specific service that dominated outright. Newer or smaller players, even good ones, didn't make the shortlist.
The winners all had years of help articles, integrations, and how-to content behind them — material an assistant can read, trust, and quote.
Most answers named the same three or four options. The assistant isn't browsing the whole market; it's reaching for the names with the most verifiable signals.
City-specific questions went to businesses with real local evidence — local reviews, local service pages, local mentions — not just the national brands.
Translate that to HVAC: when a homeowner asks "best AC repair in Orlando," the assistant reaches for the contractors with hundreds of recent reviews, detailed service pages ("AC repair from $89, same-day service"), and mentions across directories, news, and forums. The solid 3-truck shop with a one-page website and 12 reviews from 2022 doesn't get named — not because it's worse, but because the assistant has less it can verify.
Two more things stood out. The assistant personalized answers around location — several replies opened with "for your Kissimmee business" — which means local signals matter even in AI answers. And it repeatedly warned that no one can guarantee a ChatGPT recommendation — any agency promising that is selling you something.
Why they win
The assistant isn't judging quality. It's pattern-matching trust signals, and the winners all have the same ones in volume:
- Reviews — many, and recent. Volume plus recency is the single strongest signal. A shop with a handful of reviews from 2021 looks dormant to an assistant.
- Clear, citable pages. Specific service pages with real pricing and real answers — "capacitor replacement, $180–$260, same-day" beats "quality service at fair prices" every time. It's material an assistant can quote verbatim.
- Structured data. Schema markup and clean site structure tell crawlers exactly what the business is, where it serves, and what it offers.
- Years of mentions. Directories, news, comparisons, community forums — the winners have been mentioned across the web for years. That's a moat, but it's a moat built one mention at a time.
Notice what's not on the list: clever ad copy, keyword stuffing, or having the prettiest website. Assistants reward verifiable substance.
What this means for your HVAC company
The big regional contractors own the general shortlists — you're not out-reviewing them this quarter. But local, specific questions are a different contest, and the bar is low: most local competitors have thin websites, a handful of old reviews, and no structured data at all. The assistant recommending "an HVAC company in Orlando that does 24/7 emergency AC repair and offers financing" needs local, specific facts, and almost nobody is supplying them.
That's the opening, and it's time-limited. Every month the shortlists get more entrenched — and every summer, a wave of homeowners asks an AI assistant who to call.
How AI visibility is measured
There's no single dashboard for this yet, so measurement means structured testing — the same method behind this post. Here's the five-check framework we use:
- AI visibility: ask unbranded discovery questions across ChatGPT, Gemini, and Perplexity. Are you mentioned? Recommended? In what position?
- Google presence: your Business Profile, reviews, and local standing — still the raw material assistants draw on.
- Website fundamentals: can AI crawlers read your site? Is there an llms.txt file, schema markup, clean structure?
- After-hours capture: when the assistant's user clicks through at 11 PM with a dead AC, does someone answer?
- Review velocity: are real customers leaving recent reviews, in volume? Assistants treat recency and volume as trust signals.
Run the same prompts monthly and you have a trend line — the closest thing this industry has to a ranking report.
The levers that move it
- Be citable. Publish what things cost: capacitor replacement, full system installs, maintenance plans. Vague "quality service at fair prices" copy gives assistants nothing to quote. (This blog exists for exactly that reason.)
- Structure your site for machines. Schema markup, an llms.txt file, and clean crawlability. Google's own guidance says no special AI-search steps are required — just a well-built site.
- Earn reviews continuously. The winners above all have this; most local shops don't. Every completed job is a review you didn't ask for.
- Keep your Google Business Profile complete. It's still the canonical record assistants check first — hours, services, service area, photos.
- Say the quiet parts out loud. "Licensed & insured in Florida · 24/7 emergency AC repair · upfront flat-rate pricing" is exactly the kind of honest, specific claim assistants can verify and repeat.
The one-sentence version: AI visibility is earned the boring way — a clear website, real reviews, structured data, and specific claims an assistant can verify. There are no shortcuts, which is exactly why most of your competitors haven't done it.
