Should you post on one platform or all three?

Almost everybody starting out should pick one. Almost everybody starting out picks three, gets tired, and concludes content doesn't work for them.

Why one wins early

Every platform has its own shape. What lands on LinkedIn dies on Instagram. Getting good at one takes a few months of paying attention, and you can't pay attention to three things at once while also running a business.

One platform, done properly, gets you further in six months than three platforms done at a third of the effort each.

How to pick yours

Go where your buyers already are, not where you enjoy being. If you sell to businesses, that's usually LinkedIn. If you sell to consumers and the thing is visual, that's usually Instagram. If people need to trust you deeply before they buy, that's YouTube.

If two feel equally right, pick the one you'd dread less on a Tuesday night. You'll be doing it a lot.

When to add a second

Add one when the first is running without drama. That means you know what works there, you've got a list of ideas, and you're not stressed about this week's post.

If any of those aren't true, adding a platform just means two places where you're behind.

Adding one shouldn't mean doubling the work

The idea travels even when the format doesn't. One thing you've worked out can be a LinkedIn post, a reel and a video, and the thinking only happened once.

What changes is the shape. Same point, told the way that platform's people expect to hear it.

The one thing to keep in common

Your point of view. If someone finds you in two places and you sound like two different people, neither one builds.

Same beliefs, same voice, different lengths. That's how one idea becomes a presence in three places without becoming three jobs.
