The honest answer isn't a magic number — it's the highest frequency you can sustain without posting filler. For most small businesses that's a few times a week, and one true post beats five decorative ones every time.
Every year publishes new “optimal frequency” charts, and they mostly measure big brands with content teams. For a small business, the real constraint is supply: how many posts can you make that actually say something? Post daily with something true and you'll grow; post daily with quote graphics and holiday clip-art and the algorithm learns your account is skippable — and so do your customers.
Commonly two to four posts a week is the sweet spot for a small business: enough presence to stay in mind, low enough that every post can earn its place. The mix that holds up: proof of work (the thing you made or fixed today), answers to real customer questions, and the occasional human moment. That's a rhythm one owner can sustain — which matters more than any chart, because the account that goes silent for a month loses more than the one that posted twice a week all along.
Posting frequency is a second-floor question. If the Google Business Profile is incomplete or the website doesn't answer basic customer questions, fix those first — they're what search engines and AI assistants actually read when deciding whom to recommend. Social keeps you warm with people who found you; it rarely does the finding.
Volume isn't the sin — filler is. Accounts that post several times daily with real substance do fine; accounts that post daily fluff train followers and algorithms to skip them. If output quality drops as frequency rises, the frequency is too high for your content supply.
Reach dips and momentum resets, but it's recoverable — algorithms respond to what you do now more than punishing the past. The bigger cost is human: a profile silent for months reads as possibly closed. A light sustainable rhythm exists precisely to prevent that signal.
Proof of work — the job finished, the dish plated, the before-and-after. Answers to questions customers really ask. Occasionally, the human behind the business. Skip inspirational quotes and generic holiday graphics; they could come from any business, which is exactly the problem.
No — one platform done consistently beats four done thinly. Pick where your actual customers spend time (ask your last ten), own it, and let the others hold a complete profile that points to the one you maintain.
