Ask an AI assistant for the best HVAC company in Phoenix and you get a confident little answer with a few names in it. Where did those names come from? Not from a ranking somebody maintains. Each assistant assembles its answer on the spot, from sources you can actually influence. Knowing which sources is the whole game.
Most assistants now run a live web search behind the scenes, then summarize what they find. They favor businesses whose websites state their service and location plainly, that carry structured data, that appear consistently across directories and maps, and that show an active review history. When the evidence is weak everywhere, the assistant names nobody and points to a directory instead.
The answer is assembled, not stored
A common fear is that the AI "learned" an opinion of your business during training and you are stuck with it. That is mostly wrong for local questions. When the question has local intent, ChatGPT, Gemini, and Perplexity all reach for live search results and stitch the answer from what comes back. This is good news. It means the answer changes when your evidence changes. We have watched scores move within weeks of a site fix.
What each assistant leans on
Perplexity is the most transparent. It cites its sources right in the answer, and those citations are usually review sites, local guides, and business websites. If you want to see exactly which pages feed answers in your market, ask Perplexity and read the footnotes.
Google's assistants, Gemini and AI Overviews, sit on top of Google's own index and business profiles. Your Google Business Profile does heavy lifting here. An out-of-date profile with four photos and a wrong category is a handicap no website can fully cover for.
ChatGPT searches the web too, but it has a stronger habit of falling back on big platforms when it is unsure. That is why so many ChatGPT answers hand buyers to a directory instead of a business. Unsure means your evidence was not strong enough to name you.
The open market nobody talks about
Here is the finding from our scans that surprises owners most: a large share of AI answers name no business at all. The assistant hedges, describes what to look for, and links a platform. Every one of those answers is open ground. Nobody won it yet. In most local categories you are not fighting an entrenched winner. You are walking into a room where the seat is empty.
The shift is happening either way. BrightLocal's 2026 survey found 45% of consumers already use AI to pick local services, and Gartner forecasts 25% of traditional search moving to AI chatbots in 2026. The buyers are already asking. The answers are still unsettled. That combination does not last long.
What this means for your week
- Ask the three assistants your buyer's question and note who gets named. That is your scoreboard.
- Read Perplexity's citations for your market. Those pages are where the answers come from. Get cited on them or outdo them.
- Make your own site quotable: service plus city in plain sentences, structured data underneath.
- Treat your Google Business Profile like a second homepage, because for Gemini it is.
- Re-check monthly. Answers move, and the trend tells you whether your fixes work.
Our free check runs your buyer questions across the assistants, scores how often you come up, and shows who gets named instead. The same scan re-run weekly is how you catch the answers moving before your competitors do.
