Which directories does ChatGPT use?
ChatGPT doesn't use a fixed set of directories. It searches the web, and directories turn up because they rank well for buying questions. These are observations from our own testing, not a list from OpenAI.
When ChatGPT answers a question like "who are the best web design agencies in Leicestershire?", it usually runs a few searches and reads the results. Directory pages are built to rank for exactly those searches, with lists of providers, reviews and short descriptions. So they get read, and often cited. Other assistants behave in a similar way, though each searches a different index.
Which UK directories do AI assistants cite most often?
These are the ones we see in cited sources when we run UK buyer questions. How often each appears varies by sector and by question, so treat this as a starting list.
- Clutch: a B2B directory with verified client reviews. Common in answers about agencies, developers and consultancies.
- DesignRush: an agency directory with category lists by service and location.
- Sortlist: a platform that matches businesses with agencies, with profiles and reviews.
- GoodFirms: a B2B directory for software, IT and marketing firms.
- The Manifest: a business listings and guides site from the same company as Clutch.
- Google Business Profile: the listing behind Google Maps and local results. Its reviews are widely read.
- Bing Places: the Bing equivalent. It matters because ChatGPT search and Copilot lean on Bing.
- Apple Business Connect: controls how you appear in Apple Maps and Siri.
- Yell: a long-running UK business directory that still ranks for many local searches.
- Trustpilot: open customer reviews, often cited when a buyer asks who's reliable.
What about sector directories?
They often matter more than the general ones. If your buyers search a trade body or a specialist site, assistants tend to read it too.
Trades get cited from sites like Checkatrade. Solicitors and accountants appear in the search tools run by their professional bodies. Hospitality, healthcare and education all have their own. Run a few buyer questions in your sector and note which specialist sites come up in the sources. Those go to the top of your list.
Why do assistants cite directories at all?
Because directories answer comparison questions in one place. A page listing ten agencies with reviews, locations and services is exactly what an assistant needs to build a shortlist.
They also help an assistant check a business. If your name, address and services match across your site, your Google profile and two directories, the assistant can be more confident it has the facts right. If they don't match, it has reason to doubt them.
How do you find out which directories matter for you?
Follow these steps. It takes about an hour, and it tells you more than any general list.
- Write down five to ten questions your buyers would ask an assistant, including your service and your area.
- Ask each one in ChatGPT with search on, then in Perplexity, Gemini and Copilot, in fresh chats.
- Copy every source each answer cites into a spreadsheet.
- Count which directories and review sites appear more than once.
- Check whether you're listed on each one, and whether your details match your website.
- Fix the ones you're on, then join the ones you're missing, most cited first.
- Run the same questions again next month, because sources change.
Does paying for a featured listing help?
Not that we've seen. Several directories sell sponsored placements, but an assistant reads the page, not the invoice. A complete profile with real reviews gives it more to work with than a badge.
Paid placement may still be worth it for the clicks it brings from people browsing the directory itself. Judge that on its own merits, not on AI search.
