H1: ChatGPT vs Gemini vs Perplexity: Which AI Recommends Trades Businesses?

A plumber in Bergen County gets a different answer depending on which AI engine a homeowner asks. ChatGPT, Gemini, and Perplexity each pull from different data sources, apply different filters, and recommend businesses at different rates. A plumbing company can rank well on Gemini and be completely invisible on ChatGPT, and the reverse is equally common.

Consumer use of AI tools to find local businesses jumped from 6% to 45% in a single year, according to BrightLocal's 2026 Local Consumer Review Survey. That is a sevenfold increase. 63% of active AI users say they trust AI recommendations for local businesses. Meanwhile, 87% of independent HVAC and plumbing contractors have effectively zero AI citation share, per the 5WPR HVAC and Plumbing AI Visibility Index.

The gap between where customers are searching and where trades businesses are showing up is the opportunity. Understanding how each AI engine makes its picks is the first step toward closing it.

How Each AI Engine Discovers Trades Businesses

ChatGPT: The Selective Gatekeeper

ChatGPT holds 61% of AI search traffic, according to Wix Studio's AI Search Lab analysis via Contently (April 2026). It pulls local business data through Bing's index, not Google's. Research from GeekPowered Studios found that 77% of businesses ranking on page one of Bing appear in ChatGPT local search results.

But ChatGPT recommends businesses in just 1.2% of relevant local queries, per f9 Analytics. That is the lowest recommendation rate of the three major platforms. ChatGPT also applies the highest star-rating floor: 4.30 stars minimum before it will recommend a business at all.

ChatGPT favors brands with mentions in high-authority publications, consistent listings across multiple directories, and schema markup that helps the model understand what the business does. Content freshness matters less here than on the other platforms, because ChatGPT leans on training data unless the user enables browsing.

For trades businesses, this means traditional authority signals carry more weight on ChatGPT than a recently updated blog. A plumbing company with a well-structured website and consistent listings across Bing, Yelp, and the Better Business Bureau is more likely to appear than one with fresh content but thin directory presence.

Gemini: The Google Insider

Gemini has something ChatGPT and Perplexity do not: direct access to the Google ecosystem. Google Business Profile data, Maps signals, Google reviews, categories, and operating hours all feed into how Gemini evaluates and recommends local businesses.

That gives Gemini a deeper information base for local queries. Gemini recommends businesses in 11% of relevant local queries, nearly ten times the rate of ChatGPT. Its star-rating floor sits at 3.90, the lowest of the three.

Gemini reflects changes faster than ChatGPT because it is connected to the Google index in real time. Publish new content, Google indexes it, and Gemini can incorporate it within days. Technical SEO problems like duplicate content or broken canonicals hurt a business more on Gemini than on any other platform.

For trades businesses, a complete and accurate Google Business Profile is the single highest-leverage move for Gemini visibility. Missing categories, outdated hours, or sparse photos all work against a business here more than they do on the other platforms.

Perplexity: The Real-Time Researcher

Perplexity is a conversational search engine. Every question triggers a fresh web search, and Perplexity extracts and cites sources with direct links. It is the only platform of the three where visibility generates verifiable traffic back to a business website.

Perplexity recommends businesses in 7.4% of relevant local queries, with a star-rating floor of 4.10. Content freshness and traditional SEO signals carry more weight here than on ChatGPT or Gemini, because every query starts with a live web search rather than training data.

For trades businesses, Perplexity rewards well-structured content that ranks in web search results for industry queries. A plumbing company that publishes answer-shaped content with clear headings and concrete data gives Perplexity something to extract and cite. Pages with fresh, indexed content and clean structure outperform static pages with outdated information.

The Star-Rating Thresholds: A Hard Filter, Not a Ranking Factor

This is where most trades businesses get stuck. On Google Maps, a business with a 3.6-star rating can still show up if it is nearby and relevant. AI platforms treat review ratings differently. ChatGPT requires 4.30 stars, Perplexity 4.10, and Gemini 3.90 before a business enters the recommendation pool at all.

An independent plumber with 800 five-star reviews and a 4.2 average does not clear ChatGPT's bar. The same plumber easily appears in Google's local pack. This is one reason the 5WPR study found that 87% of independent contractors are invisible to AI, even when they dominate local Google reviews.

The practical implication: if an average rating sits below 4.0, fixing that gap does more for AI visibility than any other single action. Review generation is not a nice-to-have. It is a prerequisite for appearing in AI recommendations on two of the three major platforms.

Platform-Specific Strategy for Trades Businesses

To show up on ChatGPT

Focus on authority signals that exist outside the business website. Listings on Bing, Yelp, Better Business Bureau, and trade-specific directories give ChatGPT the data it needs to verify and recommend. Consistent NAP (name, address, phone) across all of these platforms matters more than content freshness. Bing Places for Business is a 15-minute fix that directly feeds ChatGPT's local index.

To show up on Gemini

Complete and update the Google Business Profile first. Photos, service categories, operating hours, and a full description all feed Gemini directly. Google reviews carry more weight on Gemini than on any other platform. Technical SEO problems that block indexing hurt a business more on Gemini than anywhere else, because Gemini pulls from the live Google index on every query.

To show up on Perplexity

Publish fresh, structured content that answers the specific questions homeowners ask. "How much does emergency plumbing cost in Bergen County" or "what to do about a burst pipe in winter" are the types of queries where Perplexity extracts and cites well-structured pages. Schema markup helps Perplexity parse what a business offers and where it operates.

What Overlaps Across All Three

The fundamentals are not different for each platform. They build on each other.

  1. Consistent business name, address, and phone across every directory and listing
  2. Correct schema markup (LocalBusiness, Organization, Service) on the website
  3. Reviews across multiple platforms, not just Google
  4. Content that answers specific questions in plain language
  5. A complete and accurate Google Business Profile

Get these right and a trades business builds a foundation that works across all three platforms. Then the platform-specific adjustments above close the remaining gaps.

The Bottom Line for Trades Businesses

A homeowner asking ChatGPT "who is the best plumber near me" gets a different answer than the same homeowner asking Gemini. Both get a different answer than Perplexity. The businesses that show up in all three are the ones that built presence across every platform the AI engines check.

45% of consumers are now using AI to find local businesses. The trades companies that build AI visibility across all three platforms now will be the ones getting recommended when 70% or 80% of homeowners start there.

FAQ

Does ChatGPT use Google rankings to recommend local businesses?

No. ChatGPT pulls local business data through Bing's index, not Google's. Research from GeekPowered Studios found that 77% of businesses ranking on page one of Bing appear in ChatGPT local results. Google rankings do not directly influence ChatGPT recommendations.

Which AI platform recommends the most local businesses?

Gemini recommends businesses in 11% of relevant local queries, the highest rate of the three major platforms. Perplexity recommends businesses 7.4% of the time. ChatGPT recommends businesses in just 1.2% of queries, making it the most selective.

What star rating does a trades business need for AI recommendations?

ChatGPT requires roughly 4.30 stars, Perplexity 4.10, and Gemini 3.90. Google Maps still surfaces businesses with ratings between 3.50 and 4.00, but all three AI platforms hold businesses to a higher standard before recommending them.

Should a trades business optimize differently for each AI platform?

The fundamentals overlap: consistent listings, schema markup, reviews, and a complete Google Business Profile work across all three. Platform-specific adjustments matter for the last mile. ChatGPT rewards directory presence and authority signals. Gemini rewards Google ecosystem completeness. Perplexity rewards fresh, well-structured content.

How can a plumbing or HVAC company check its AI visibility?

Run a free AI visibility audit through FirstCall Visibility. The audit checks whether a business appears in AI recommendations across ChatGPT, Gemini, and Perplexity for the keywords customers actually use, and shows exactly where the gaps are.
