Business social network sites beyond the obvious one, the six kinds of place a professional audience gathers and what each is good for
Most of the useful ones are not general networks at all, and choosing by audience rather than by size changes which two you should be in.
Published by AI Knows Us · Updated 22 October 2026
There is one general professional network that most people mean by the phrase, and then there are five other kinds of place where a business audience actually gathers: regional professional networks, trade and industry communities, practitioner platforms built around work rather than profiles, closed group chats, and public company records. For most businesses the right answer is one general network kept current plus one place where your specific buyer already talks, and the second one does more work than the first.
Read against the United Kingdom geo target on its own on 22 October 2026, business social network sites draws 70 searches a month in the United Kingdom, and against the India target on its own on the same day it draws 30 a month in India. Each figure is one country alone.
The six kinds, and the job each one does
One, the general professional network
Profiles, a feed, a company page, a jobs board and a paid advertising platform in one. Its job is to be the place a stranger checks you after hearing your name, which makes it the one place you cannot afford to have out of date. Treat it as the credential, and be realistic that its feed rewards individual accounts over company pages.
Two, regional professional networks
Several countries have their own established professional network with a local user base, and in German speaking markets in particular a candidate or a counterpart may be more active there than on the international one. If you sell into a specific country, check which network the people you want actually keep current rather than assuming the largest one wins everywhere.
Three, trade and industry communities
Association forums, sector specific boards and the member directories behind them. Unfashionable, often badly designed, and frequently the single highest intent audience available to a specialist supplier, because membership is itself a qualification. The route in is answering questions, not posting announcements.
Four, practitioner platforms organised around work
Places where the unit is a portfolio, a repository or an answer rather than a profile: code hosts for engineers, portfolio sites for designers, question and answer sites for technical fields. The audience is there to evaluate work, which makes these the best places to be judged on competence and the worst places to advertise.
Five, closed group chats
Invite only communities on chat platforms, where a lot of senior conversation now happens in private. You cannot buy your way in and you cannot measure it with a dashboard. One person from your team being genuinely useful in two of these outperforms a quarter of posting on a public feed, and it is the channel most plans leave out because it cannot be reported on.
Six, public company records
Not a social network and it belongs on this list, because it is where a cautious buyer goes next. In Britain a prospect can look up a company filings and officers before replying to an email. Keeping those records tidy and current is a reputational task even though nobody thinks of it as marketing. Four surfaces each do a different job in a British purchase, and the record check is the one that happens after the others have gone well.
How to choose two rather than six
Four questions, answered from your own data rather than from an article.
- Where did your last ten customers come from. Ask them. This single answer usually settles it.
- Which place requires a credential to join. A barrier to entry is a filter, and a filtered audience is worth more than a large one.
- Where can you be useful weekly without running out of things to say. A channel you abandon is worse than one you never joined.
- Which place would your buyer check before replying to you. That one is not optional, however little you enjoy it.
What to publish where, when the answer is two places
The general network gets the credential: a current profile, a clear description of what you do, and evidence. The specialist place gets the substance: the answer, the method, the thing you learned. Do not reverse these. Posting your detailed method into a general feed gets a polite reaction from people who cannot use it, and posting your credentials into a specialist community reads as an advertisement to the only people who could have hired you.
Different sectors split their audiences across different platforms for structural reasons rather than fashionable ones, and it is worth seeing one worked through. A logistics company running one network for the shipper and another for the driver is a clean example of two audiences for one business living in two completely different places.
What a network cannot do, whichever one you pick
None of these surfaces is a page you own. A profile is a tenancy: the platform decides who sees it, what it looks like and whether it continues to exist in its current form. So the work done on any of them should produce something on your own site as well. The practical version of that rule is simple. If you wrote something good in a community answer, that answer is the first draft of a page on your own domain, and the page is the asset.
Questions about choosing a business network
Is a company page worth maintaining on a general network
Yes, as a credential rather than as a channel. A stranger checks it and a dormant one raises doubt. Keep it current and expect the reach to come from individual accounts.
How do we find the trade community for our sector
Ask three customers where they go to ask peers a question, and look at which association your competitors list in their footers. Both routes take an afternoon and are more reliable than searching for a list.
Are closed communities worth the time if we cannot measure them
Where senior buyers are in them, yes. Measure the proxy rather than the channel: count the enquiries that arrive already knowing who you are, because that is what being present in a private room produces.
Should we be on every network to protect the name
Register the name where it is free, then publish on two. A profile with nothing behind it is worse than no profile, because it suggests a business that started something and stopped.
What is the minimum upkeep for a network we are not focusing on
A correct description, a current contact route and one post a quarter so the account does not read as closed. That is enough for a surface whose job is to confirm you exist.
The place your buyer now checks that has no profile to keep current
There is a seventh surface and nobody has an account on it. A buyer asks an assistant who to use for the thing you do, and the answer names a company or two, built from whatever pages the assistant could read. No profile to complete and no feed to post into. At AI Knows Us we measure, dated, whether ChatGPT, Gemini, Perplexity, Claude and Google AI Overviews name a business when that question is asked. For a company deciding which two networks to invest a year in, it is worth knowing what gets said about it in the one place where the answer is already being given.
