When asked the identical “best [category] in [city]” question, ChatGPT, Perplexity, and Google AI Overviews named the same single top business only a minority of the time. Each engine reads and weights its trusted sources differently — so checking just one engine can tell you you're winning while you're invisible on the other two.
What we did
Recommd runs live, grounded queries against multiple AI engines for a living — it's the core of our free audit. So we have a front-row seat to something most business owners never get to see: the same question, asked of three different AI assistants, side by side. We compiled the patterns from running identical “best {category} in {city}” queries across common local categories (gyms, med spas, dentists, restaurants, hair salons, plumbers) and major US metros, comparing what each engine named.
Methodology note: these are live grounded-search results, which shift over time as sources re-index. The figures below describe the patterns we observe consistently, not a fixed leaderboard. We report directional findings, not precision claims — anyone can reproduce the disagreement by asking the three engines the same question themselves.
What we found
- Finding 1 — Full agreement is the exception, not the rule
Across categories, all three engines naming the same single top business was uncommon. Far more often, each engine led with a different name, or shared only one or two names out of several.
- Finding 2 — A business can be #1 on one engine and absent on another
The most striking pattern: businesses that lead Google AI Overviews regularly fail to appear in Perplexity or ChatGPT at all, and vice versa. Strong visibility is not transferable by default.
- Finding 3 — Google AI leans hardest on Maps and Business Profile
Its picks correlate most tightly with Google Business Profile completeness and review signals, reflecting its roots in core local search.
- Finding 4 — Perplexity and ChatGPT reward third-party presence
Businesses named in “best of” roundups, review platforms, and category directories surface more on these engines — even when their own website is thin.
- Finding 5 — Consistency is the shared denominator
The businesses named across all three engines had one thing in common: clean, consistent details everywhere. When name, address, phone, and category match across sources, every engine is confident enough to name you.
Recommd runs your customers' question across engines and shows, per engine, whether you're named, who's recommended instead, and the sources each one cited. No signup.

The single biggest mistake we see is treating “I checked ChatGPT and I'm there” as proof of AI visibility. Our data says that's a coin flip at best. Your customers don't all use the same assistant — and the engine you didn't check might be handing every one of its users to a competitor.
The encouraging part: the fixes that lift you on all three are the same shared signals — a complete Google Business Profile, a steady flow of recent reviews, consistent details everywhere, and presence on the directories and “best of” lists your category trusts. Win the shared signals and you stop depending on any single engine's quirks. Our guide on which sources AI assistants trust breaks down each one.
And because the engines disagree and the answers move, periodic multi-engine checking is the only honest way to know where you stand. Recommd's paid report and 90-day monitoring track all of them on a schedule.

Frequently asked questions
- Do ChatGPT, Perplexity, and Google AI recommend the same businesses?
Mostly no. In our 2026 review of identical 'best [category] in [city]' queries across local categories, the three engines named the same single top business in only a minority of cases. Each engine weights its trusted sources differently, so a business that's invisible on one can be the top recommendation on another. - Why do different AI engines give different business recommendations?
Because they read different sources and weight them differently. Google AI Overviews leans heavily on Google Business Profile and Maps; Perplexity favors well-structured, recently-updated pages and review platforms; ChatGPT draws from a wider mix including directories and 'best of' articles. Different inputs produce different shortlists. - Does checking only ChatGPT tell me my real AI visibility?
No. Checking one engine is a single data point that can badly mislead you. A business can be named by ChatGPT and completely absent from Perplexity and Google AI Overviews. Real AI visibility means being named consistently across the engines your customers actually use, which requires checking all of them. - Which AI engine matters most for my business?
It depends on your customers, but the safer answer is all of them. Google AI Overviews has the largest reach for local intent, Perplexity is growing fast among researchers, and ChatGPT is the default assistant for tens of millions. Optimizing for the shared signals — profile completeness, reviews, consistent details, trusted directories — lifts you across all three at once. - How can I check my visibility across all AI engines at once?
The free Recommd audit runs your customers' question across multiple engines and shows, per engine, whether you're named, who's recommended instead, and the sources each one cited — so you see the disagreement directly instead of guessing from one.
