How to Share Your Expertise on LinkedIn Without Sounding Like a Know-It-All

You're an expert. You're supposed to share what you know. But there's a difference between demonstrating expertise and lecturing everyone on LinkedIn. 😂

The goal isn't to prove you're the smartest person in the room. It's to make what you know useful to the room.

Teach from experience, not from a pedestal

Instead of constantly telling people what they must do, try: “I've noticed…”, “What I've found works better is…”, or “One mistake I keep seeing is…”

You're still teaching. You're showing us where the expertise came from.

Give us the example

If you say “Your positioning needs to be more specific,” show us.

Before: I help businesses grow through strategic marketing.

After: I help independent financial advisers turn their expertise into content that attracts business owners.

Talk to the person you're trying to help

Experts can accidentally write for peers. Your expertise might be sophisticated; your explanation doesn't have to be.

It also helps to know who you actually want in your audience.

Make the reader smarter

Ask: Will the reader understand something better after reading this?

Not: Will they understand how smart I am?

Your expertise is the ingredient. Communication is how you make it useful.

Frequently Asked Questions

How do I share expertise on LinkedIn without sounding condescending?

Teach from experience using phrases like "I've noticed" or "What I've found works better is," rather than telling people what they must do.

What's the difference between demonstrating expertise and lecturing?

Demonstrating expertise makes the reader smarter. Lecturing is written to prove how smart you are. Ask whether the reader will understand something better after reading. That's the test.

Why does giving examples matter more than stating advice?

Vague advice like "be more specific" doesn't teach anything on its own. A concrete before-and-after example shows the reader exactly what specific looks like.

Who should I be writing for when I share what I know?

The person you're trying to help, not your peers. Know who you actually want in your audience before you write.
