Which sources AI assistants actually cite

By Marcus, founder of PipelineOS · last reviewed 25 September 2026 · sources on the benchmarks page

Assistants build answers about local businesses from a small and fairly predictable set of source types. Here is the shape of it, how to find your own market's version in an afternoon, and which one matters most.

In short

AI assistants build answers about UK local businesses from a small set of source types: directories and marketplaces, review platforms, trade bodies and registers, local and trade press round-ups, community threads, and the business's own site last. The specific set differs by trade and area, and can be found by asking two or three assistants the question a customer would ask and writing down every source named. For a business selling into one town, a Google Business Profile is the strongest single source.

What an assistant reaches for

Ask an assistant to recommend a tradesperson, a clinic or a supplier in a UK town and the answer is built from a fairly predictable set of source types. It is worth knowing the shape of that set, because it tells you where the work is.

  • Directories and marketplaces with enough structure to be parsed and enough age to be trusted.
  • Review platforms, because they carry third-party sentiment attached to a named business.
  • Trade bodies, schemes and registers, which are the strongest signal in regulated and certificated trades because membership is checkable.
  • Local and trade press, including the listicle-style round-ups that rank for “best X in Y”.
  • Forums and community threads, where real people name real firms.
  • The business's own site, last, and mostly for facts rather than for judgements.

Notice what is missing from that list: your brochure, your social posts, and anything you wrote about yourself. Those establish what you claim. They do not establish that anybody agrees.

Why the same names keep coming up

If you have asked an assistant about your own market you will have noticed it returns the same handful of sources again and again. That is not favouritism. A source gets reached for repeatedly when it is structured, stable, old, widely linked to and unambiguous about which business is which. Directories are built to be exactly that, which is why they punch above their apparent weight.

It also means the set is discoverable. You can simply ask, in several phrasings, and write down what comes back. That list is your target list, and it will be shorter than you expect and more boring than you hoped.

How to build your own target list

  1. Ask two or three different assistants the question a customer would ask, naming your trade and your town. Not your company name.
  2. Write down every source that is named or linked, not just the businesses.
  3. Repeat with the phrasings a suspicious buyer would use: best, reviews, cheapest, near me, and the compliance word your trade turns on.
  4. Count which sources recur. Anything appearing in most answers belongs on the list.
  5. Check which of those you are already in, and whether the details match what is on your site exactly.

That is a genuinely useful afternoon and you do not need an agency to do it. The part that takes longer is the submissions, the claim processes, the ones that require membership or evidence, and the ones that quietly reject you.

The one that matters most locally

For a business selling into a town rather than nationally, the single strongest source is a Google Business Profile, because it is the record Google itself holds about you and it feeds both the map pack and a great deal of downstream local data. It is free, it takes verification tied to the business owner rather than an agency, and it is the most common gap we find.

We say this on every page where it is relevant, including the ones where it argues against buying anything from us. If you do nothing else on this page, do that.

Where this stops being true

Two honest limits. First, source sets differ by market: a regulated clinic and a scaffolding firm are assembled from different places, so a generic list is worth less than fifteen minutes of asking about your own trade. Second, these systems change. What an assistant reached for in spring is not necessarily what it reaches for now, which is why anything on this page is dated and why a service sold on a permanent formula should be treated with suspicion.

Common questions

Which websites do AI assistants cite most for UK trades?

Directories, review platforms, trade bodies and registers, local and trade press round-ups, and community threads, roughly in that order of how often they are reached for. The specific set differs by trade and by area, which is why the practical answer is to ask an assistant about your own market and write down what it names.

Does getting listed in directories still work?

For being cited, yes, and more than it does for ranking. A directory listing is a structured, third-party record that a business exists, is in a place, and does a thing. That is precisely the sort of corroboration an assistant is looking for.

Do I need to pay for directory listings?

Usually not for the ones that matter. Most of the recurring sources have a free listing tier and the paid upgrade buys placement rather than existence. Existence is the part that counts here.

What about Wikipedia?

It is a strong source where it applies and almost never applies to a local service business. Notability rules mean most trade firms will never qualify, and attempting it anyway wastes time and irritates editors.

Can an agency get me into these sources?

Into the open ones, yes, and it is mostly patient admin rather than expertise. Into the editorial ones, sometimes, by being genuinely worth writing about. Anyone claiming a guaranteed route into press or trade bodies is describing something that does not exist.

The list is shorter than you think

Most trades have eight or ten sources that matter and are already in two of them. Call and we will find out which two.
