ChatGPT Ranking Factors: What 1,000 Businesses and 143 Experiments Actually Showed
Search for "ChatGPT ranking factors" and you'll find confident lists written by people who never tested anything. This one is different: we ran 143 experiments across 1,000+ real local businesses, comparing who ChatGPT recommends against who ranks on Google, then checked every factor we could measure. Here's the full scoreboard — including the factors that failed.
The factors that matter (in order of evidence strength)
1. Having a website at all — the binary gate
The strongest finding in our data, and it isn't close. Businesses with no website appeared in ChatGPT's recommendations 0% of the time, across every trade and city we tested. ChatGPT cites business websites directly in 82% of its local recommendations. No site, no citation, no recommendation. (47% of local service businesses fail this single factor.)
2. Multi-platform review presence
Businesses ChatGPT recommends are listed on more review platforms — Yelp, Trustpilot, Checkatrade, trade-specific sites — than businesses it ignores. Our clearest case study: two comparable businesses where the one on four platforms was consistently recommended and the one with a single (larger!) Google review base was invisible. External 2026 research now ranks third-party citations and review-site presence among the top AI-visibility factors industry-wide.
3. Google ranking position (indirectly)
61.5% of ChatGPT's picks ranked in Google's top 3. Not because ChatGPT reads Google — it doesn't — but because the same fundamentals (real business, real reviews, clear website) rank you in both places. Don't abandon SEO; it travels.
4. Title tags and content matching the question
ChatGPT finds pages through Bing search, and Bing matches words. Pages titled "[trade] in [town]" win the queries phrased that way. Our suburb experiments made this concrete: 87% of suburb-query winners had the suburb name woven through their actual page text. "Areas we cover" footer lists did nothing.
5. Clear specialist identity
For specific queries ("MVHR installation," "emergency locksmith"), ChatGPT recommends businesses whose pages visibly claim that specialty. Generalists with buried services lists lose these queries to smaller, clearer specialists.
6. Linked social profiles (minor)
Recommended businesses averaged 2.3 linked social platforms vs 1.9 for invisible ones. Real but small — do it, don't obsess over it.
The factors that failed our tests
This is the part nobody else publishes, because these are the easiest things to sell:
| Factor | What we found |
|---|---|
| Schema markup | Under 5% correlation across 1,000 businesses |
| robots.txt allowing AI bots | Slightly negative correlation — ChatGPT reaches you via Bing, not direct crawling |
| FAQ pages | Inconsistent, sometimes negative |
| llms.txt | Negligible (+6%, one trade only) |
| Blogging | Negative correlation — invisible businesses blogged more |
| Content freshness | Negative correlation |
| More Google reviews | No difference in medians — breadth beats depth |
A caveat we're upfront about: our data is correlational at scale, and one famous counter-example exists — a village locksmith who hit #1 in ChatGPT crediting schema and llms.txt. The catch: a village of 2,500 people has near-zero competition, where anything works. In contested markets, the table above is what the data supports.
Two structural findings most "factor lists" miss
Intent fragmentation: "best plumber in Manchester" and "emergency plumber in Manchester" returned 95% different businesses. Every phrasing is a separate contest — being visible for one query tells you nothing about the others.
Suburb isolation: city-level and suburb-level queries shared 0% of recommendations in our tests. If you serve twelve suburbs, you're in twelve separate races, and most businesses haven't entered eleven of them.
What to do with this
Check the factors that matter for your own business — the free audit runs your trade and town through ChatGPT, Gemini and Perplexity live and scores you against exactly this list. The fixes are mostly a week of unglamorous work: a readable website, three more review platforms, Bing Places, retitled pages. That's the whole game, and almost none of your competitors have done it.
