Six months ago, the AI search market had a clear pecking order. ChatGPT led. Gemini and Perplexity were neck and neck for second. Claude was an afterthought for local search.
That order is breaking apart. New data from Search Engine Journal, published in September 2026, shows the market consolidating in directions nobody predicted.
Perplexity dropped from 7.91% of AI chatbot referral share in June to 4.31% in August. During the same period, Gemini rose from 7.94% to 27.3%. Claude climbed from 1.6% to 8.9%. ChatGPT still leads but the gap is narrowing.
For a trades business owner, this is not an academic story about market share. The platforms homeowners use to find plumbers, electricians, and HVAC companies are changing. A content strategy built around visibility in ChatGPT six months ago may be missing where the homeowners actually are today.
What the Numbers Say
Search Engine Journal reported the referral share data in September 2026. The numbers track how much traffic AI chatbots send to business websites. Here is how the major platforms shifted between June and August:
| Platform | June 2026 | August 2026 | Direction | |---|---|---|---| | ChatGPT | Leading | Still leading | Stable | | Gemini | 7.94% | 27.3% | Rising sharply | | Claude | 1.6% | 8.9% | Rising sharply | | Perplexity | 7.91% | 4.31% | Dropping |
Gemini more than tripled its share. Claude more than quintupled. Perplexity lost nearly half its share in two months.
SOCi's 2026 Local Visibility Index adds another layer. That report analyzed 350,000 business locations across 2,751 brands and found that Gemini recommends local businesses 11% of the time. ChatGPT recommends 1.2%. Perplexity recommends 7.4%. Gemini's recommendation rate is nearly ten times ChatGPT's, and Perplexity is dropping.
The market is not collapsing around one winner. It is consolidating around two or three platforms, and Perplexity is not one of them.
Why Perplexity Is Losing Ground
Ross Hudgens, CEO of Siege Media, flagged the trend in a LinkedIn post. Perplexity's market share has been shrinking for months. The platform built its reputation on live web search and inline citations. That value proposition competes with Google AI Overviews, which now does the same thing but is integrated into the search experience 4 billion people already use.
For trades businesses, the practical effect is simple. Time spent optimizing for Perplexity visibility is time spent on a shrinking audience. Time spent on Gemini and ChatGPT is time spent where the homeowners are moving.
Why Gemini Matters More for Local Trades Businesses
Gemini has a structural advantage that ChatGPT and Claude do not. It is grounded in Google's ecosystem. When Gemini answers a local query, it pulls from Google Maps, Google Business Profile data, Google reviews, and the same local index that powers the search results homeowners already trust.
SOCi's 2026 Local Visibility Index found that business profile information was 100% accurate on Gemini, compared to 68% on ChatGPT. Gemini's recommendation rate of 11% is nearly ten times ChatGPT's 1.2%. The data quality gap explains the recommendation gap. Gemini has better data, so it makes more confident recommendations.
For a trades business, this means Google Business Profile optimization has a double benefit. It improves your Google Maps ranking, which you were already doing. It also feeds Gemini directly, which is the fastest-growing AI platform for local recommendations. A plumber with a complete Google Business Profile, consistent NAP data, recent reviews, and LocalBusiness schema is optimizing for both Google Search and Gemini at the same time.
Why Claude Is Rising
Claude's referral share grew from 1.6% to 8.9% in two months. That is the fastest percentage growth of any major AI platform. Claude is built by Anthropic and is increasingly embedded in business tools and enterprise search environments.
For local trades businesses, Claude's rise matters less in the short term than Gemini's. Claude's local recommendation behavior is less studied than ChatGPT's or Gemini's. But the growth trajectory means it cannot be ignored. A trades business that optimizes for the fundamentals (consistent listings, schema markup, specific website content, strong reviews) is optimizing for Claude too. The fundamentals overlap across platforms.
What to Prioritize Now
1. Google Business Profile Above Everything
Gemini's rise means Google Business Profile is more important than it has ever been. Gemini reads it directly. ChatGPT increasingly aligns with Google's index, with Google alignment rising from 12% to 33% in recent months, per SOCi. The single highest-leverage action for a trades business is completing and maintaining the Google Business Profile.
Fill every field. Upload photos. Post service updates. Respond to reviews. Keep the business category accurate. List the service area. The Google Business Profile feeds Gemini, Google Maps, Google Search, and indirectly ChatGPT. One profile, four platforms.
2. Website Content That Answers Specific Questions
The specificity gap is the difference between AI naming your business and AI recommending it with confidence. The Courtyard AI Visibility Index found that business websites account for 39% of citations when AI answers specific questions about a named business. In 42% of those answers, the business website is the only source the AI uses.
If the website has generic content, the AI has nothing specific to cite. If the website has specific service descriptions, starting prices, and a clear service area, the AI can give a confident answer on any platform.
3. Reviews That Name the Service and the Town
SOCi found that businesses recommended by ChatGPT average 4.3 stars. Businesses below 4.0 are excluded entirely. But star rating is the floor, not the ceiling. Review text matters. A review that says "they fixed the burst pipe in our Clifton basement within an hour" tells the AI the trade, the town, and the quality. "Great service" tells the AI nothing.
Ask every satisfied customer for a review that names the specific job, the town, and what the technician did. The review strategy that worked for Google still works for AI. The difference is that AI reads the review text more carefully than Google's algorithm does.
4. Stop Investing in Perplexity-Specific Optimization
Perplexity is not dead. Its 4.31% referral share is still meaningful. But it is shrinking while Gemini and Claude are growing. If a trades business has limited time and budget, the order of priority is clear: Gemini first (through Google Business Profile), ChatGPT second (through directory consistency and third-party mentions), Claude third (through the same fundamentals), Perplexity last.
Perplexity rewards fresh, well-structured content and live web search. Those investments are not wasted. But building a Perplexity-specific content strategy while Gemini triples its market share is spending money on a platform that is losing the race.
What the Consolidation Means for Trades Businesses
The AI search market is consolidating. Gemini and ChatGPT are pulling away from the pack. Claude is rising fast. Perplexity is falling. The platforms that matter for local trades businesses are the ones with the most users and the best data.
Gemini has the best local data because it reads Google Maps. ChatGPT has the most users. Claude is growing the fastest. A trades business that invests in the fundamentals (Google Business Profile, schema markup, specific website content, strong reviews) is visible on all three. That is the strategy that survives platform shifts.

FAQ
Which AI platforms should trades businesses prioritize for visibility?
Gemini and ChatGPT are the top priorities. Gemini recommends 11% of local businesses and is growing the fastest in referral share. ChatGPT still leads in users but recommends only 1.2% of local businesses. Claude is rising quickly. Perplexity is dropping and should be the lowest priority for trades businesses with limited time.
Is Perplexity still worth optimizing for?
Perplexity's referral share dropped from 7.91% to 4.31% between June and August 2026, per Search Engine Journal. Its market share is shrinking. The content investments that help with Perplexity (fresh content, structured data) also help with Gemini and ChatGPT. But a Perplexity-specific strategy is spending on a platform that is losing ground.
Why is Gemini growing so fast for local business recommendations?
Gemini is grounded in Google's ecosystem. It reads Google Business Profile data, Google Maps, and Google reviews directly. SOCi's 2026 Local Visibility Index found 100% data accuracy on Gemini versus 68% on ChatGPT. Better data produces more recommendations. Gemini's recommendation rate of 11% is nearly ten times ChatGPT's 1.2%.
How does Claude's growth affect local trades businesses?
Claude's referral share grew from 1.6% to 8.9% in two months. It is the fastest-growing AI platform by percentage. Claude's local recommendation behavior is less studied, but the fundamentals that work for ChatGPT and Gemini (consistent listings, schema, specific content, reviews) also work for Claude. Optimizing for the fundamentals covers all three.
Should I still maintain a Google Business Profile if homeowners are using AI search?
Yes. A complete Google Business Profile is the single highest-leverage action for AI visibility. It feeds Google Maps, Google Search, and Gemini directly. ChatGPT is increasingly aligned with Google's index. One profile feeds four platforms. Dropping Google Business Profile to chase AI visibility is like removing your foundation to build a second story.
