Ask this question online and you'll get answers like "3 to 5 times per week on Instagram, once a day on Facebook, twice a day on Twitter." Those numbers come from studies about engagement rates, not from the reality of running a business without a marketing team.
Here's a more honest answer.
Consistency beats frequency
The algorithm rewards accounts that show up regularly. So does your audience. But showing up three times a week for a month and then going quiet for six weeks is worse than posting once a week without fail. Inconsistency signals to both platforms and people that you're not serious about being there.
Before you set a posting schedule, ask yourself what you can actually sustain. Not in a good week. In a normal week, when things are busy and something else needs your attention.
A realistic starting point
For most small businesses without a dedicated marketing person, three posts per week is a reasonable target. That's enough to stay visible without requiring your life to revolve around content creation. Two posts a week is fine if they're good. One post a week is better than sporadic bursts followed by silence.
What's not fine is posting seven times one week, disappearing for three, then posting twice, then nothing for a month. That's the pattern most businesses fall into when there's no system behind the content.
Platform matters
Instagram and Facebook reward consistency over volume. LinkedIn is more forgiving of lower frequency but expects more substance when you do post. If you're stretched thin, pick one platform and do it well before spreading across three.
Quality over quantity, but don't hide behind it
"I only post when I have something worth saying" sounds reasonable. In practice it usually means posting twice a month and wondering why nothing is growing. Your audience needs enough touchpoints to actually remember you exist.
The goal isn't to fill a feed. It's to show up often enough that when someone needs what you offer, your name is already in their head.
The real answer
Post as often as you can without sacrificing quality or consistency. Build a system that makes content creation repeatable, not something you scramble for on the day you need to post. That's what separates businesses that grow on social from ones that stay stuck.
If you don't have that system yet, that's exactly what the right marketing partner helps you build.
If this sounds like the kind of help your business needs, a short conversation is the best next step.
