When a homeowner's AC fails in July, they don't always open Google and type "HVAC company near me" anymore.
Increasingly, they open ChatGPT, Perplexity, or Google's AI Overview and ask something like:
"Who's the best HVAC company in Dallas?"
Or: "Which plumber near me has the best reviews?"
The system answers. It gives two or three names. The homeowner picks one and calls.
If your company isn't in that answer, you didn't lose to a competitor in the search results. You were never in the conversation.
This is the new front door for contractor leads — and most contractors have no signal in it at all.
Why AI Engines Give Different Answers Than Google
Google's traditional search returns ten blue links and a Maps pack. The buyer selects from a visible list.
AI engines work differently. They synthesize information from across the web and give a direct, specific recommendation. They name companies. They describe them. They speak with authority about who serves which area and which trade.
The inputs those AI engines use are not the same as traditional SEO signals. You don't rank in ChatGPT by having the highest Domain Authority. You get named because:
- Your business entity is well-defined and consistent across the web
- Your service area, trade, and specialty are clearly associated with your company name
- You have multiple credible data sources saying the same things about you
- You have enough citation density in local directories, review platforms, and news mentions
- Your website and schema describe your services in a way machines can parse accurately
This is Generative Engine Optimization — GEO — and it's the core of what 6 Signal's method is built around.
The Six Layers That Feed AI Recommendations
AI engines don't pull from one source. They aggregate signals from across the open web. The contractor who gets named is usually visible in most or all of these layers.
Your Google Business Profile
Google's own AI Overviews heavily weight GBP data. If your profile is incomplete, your service area is wrong, or your category is misconfigured, Google AI won't recommend you confidently.
Citation consistency
If your name, address, and phone number appear differently across Yelp, Angi, BBB, HomeAdvisor, and Apple Maps, AI systems detect the inconsistency and reduce confidence in your data. Clean, consistent citations are not optional — they're table stakes.
Your website's semantic structure
AI systems read your website. They need to understand: what trade, what service area, what specific services, what differentiator. Vague websites with no schema and no location signals give AI nothing to work with. They skip you.
Review volume and recency
Review signals feed AI confidence. A contractor with 80 reviews in the last 12 months looks like an active, legitimate business. One with 10 reviews from 2021 does not. Recency matters more than most contractors realize.
Third-party mentions and authority signals
Local news coverage, contractor association memberships, trade publications, and local blogs that mention your company name in context all feed AI entity understanding. These signals tell AI systems that you are a real, active business in your market.
Answer engine presence
Perplexity, you.com, and similar platforms pull from crawled web content. If you have no content that answers contractor-specific questions in your trade and market, you have no presence in those answers.
What Most Contractors Are Missing
Most contractors we audit are missing three or four of these layers entirely.
The most common gaps:
- GBP is incomplete or has wrong service areas — Google AI won't recommend a company confidently if the fundamental business data is inconsistent
- Citations conflict — Three different addresses, two different phone numbers, and four different business names across directories
- Website has no schema — The site looks fine to a human but is invisible to a machine trying to understand who you serve and where
- Review cadence has stalled — 40 reviews from 2022 with none since then reads as a business in decline
- No content that answers questions — Nothing on the site addresses the queries homeowners are actually running
These aren't technical problems. They're data problems. And they're fixable.
What to Do First
If you want to start showing up in AI recommendations for your trade and market, prioritize in this order.
Fix your Google Business Profile completely. Every field populated. Correct primary and secondary categories. Service area maps that match where you actually work. Recent photos. Q&A populated. Posts active. This is the single highest-leverage action for AI visibility.
Audit and clean your citations. Check every major directory. Reconcile name, address, and phone to one consistent version. Suppress or correct conflicting listings. A tool like Whitespark or BrightLocal can surface the conflicts fast.
Add local service pages to your website. One page per service type. One page per major service area if you cover multiple markets. Include trade, location, and specifics. Write for clarity, not length. Short, structured, and specific beats long and vague every time.
Implement schema markup. LocalBusiness schema at minimum. ServiceArea schema. Review aggregate schema if you have structured data. This is machine-readable metadata that directly feeds AI understanding of your business entity.
Build a review system. Automate review requests as part of every job close. 40 reviews in a year beats a burst of 60 reviews and then silence. Consistency reads as an active business; spikes followed by gaps do not.
Most contractors won't do all of this. That's what creates the gap — and the opportunity.
The contractors who show up in ChatGPT recommendations in your market are not necessarily the best operators. They're the ones who have the cleanest signal across the most layers.
That signal is buildable. It just requires doing it systematically, layer by layer.
If you want to see exactly where your company stands across all six layers — and where your top competitors are showing up instead — that's what the Visibility Audit is built for. You get the full read regardless of what you decide afterward.
