Why the list is always too long
Ask which platforms a small business should be on and the answer usually arrives as a list of nine, ranked by audience size. That ranking is real. It is also close to useless, because it answers a question you were not asking.
You are not choosing where the most people are. You are choosing where you can show up every week for a year without resenting it. Those two questions have different answers, and the gap between them is why so many businesses hold five accounts and post on one.
An account you abandoned is worse than one you never opened. Visitors find it, see that the last post was fourteen months ago, and draw a conclusion about whether you are still trading.
Two filters, and a platform must pass both
The usual advice supplies one filter: go where your customers are. It is correct and it is half the job, which is why the shortlist it produces never survives a real week.
The second filter is production. Run both, and keep only what passes both:
- Presence. Are the people who buy from you already there, in the way they buy from you?
- Production. Can you make what this platform expects, every week, indefinitely?
A platform that passes the first and fails the second is not a platform you are on. It is a platform you have an account on.
Filter one: where your customers already are
Skip the demographic charts and use your own evidence. Ask the next five customers where they found you. Look at which platform sends the messages you actually answer. Check what your three nearest competitors keep up rather than what they opened.
Local and considered purchases behave differently from impulse ones. A roofer, a dentist, and a solicitor are found through search and recommendation. A boutique, a bakery, and a salon are found through pictures. That difference matters more than any headline user count.
Filter two: what you can actually produce
Every platform has a native unit, and the question is whether you can make that unit on a normal week, in your normal working conditions.
Photographs of finished work: reachable for most trades and shops with a phone. Short video with a face and a voice: reachable for some, and genuinely hard for others. Written opinion with a professional angle: reachable if you enjoy writing.
Answer for a bad week, not a good one. The platform you can serve in a busy fortnight is the one you will still be posting to next year.
The one most local businesses skip
Google Business Profile rarely appears on these lists, because it hardly feels like social media. For a business with an address or a service area it is frequently the highest return surface available.
The reason is intent. Someone scrolling Instagram is browsing. Someone reading your Google listing has already searched for what you sell and is deciding between you and two competitors. Posts, photos, and hours on that listing land in front of a person with their wallet already out.
It also accepts exactly the material you already have. The same photograph of finished work that becomes an Instagram post works there, and it takes no extra production.
Running both filters, worked through
A kitchen fitter, working from evidence rather than charts. Customers arrive through search and word of mouth, and they want to see finished work. Production is a phone camera on site, realistically twice a week.
Presence points at Google Business, Facebook, and Instagram. Production agrees with all three, because each accepts a photograph and a short caption. TikTok passes presence for a younger audience and fails production, since nobody on that crew is filming a piece to camera on a Thursday.
The shortlist is Google Business and Instagram, with Facebook third if the local groups are active. Two of them get everything. That answer took ten minutes and no research.
Why two done properly beats five done thinly
Two accounts posted to weekly look like a business that is trading. Five posted to occasionally look like a business that started something and stopped, five times over.
Two is also what a real week supports. One batching session comfortably fills two platforms, and a realistic posting rhythm assumes you are serving a short list rather than a long one.
When to add another
Add one when the current two are genuinely handled, meaning you have posted weekly for three months without heroics, and when a specific customer question keeps arriving from somewhere you are absent. Add it for a reason you can name.
Never add one because a competitor opened an account. You have no idea whether theirs is working, and neither do they, if nobody is reading the numbers.
How Postd handles more than one
The second filter gets easier when production is not your bottleneck. That is the part Postd takes on.
It prepares a week from your own website, then adapts each post to the account it is going to, so one idea arrives dressed for each room rather than pasted identically everywhere.
You review the week once and approve it, and nothing publishes without your approval. The connected accounts and the full loop are on the How it works page.
Your next step: ask your next five customers where they found you, then cut your list to the platforms that pass both filters.
