I’ve spent the last 6 months knee-deep in LinkedIn, testing, posting, analyzing, investing thousands of dollars, and learning from the best in the game.
I followed the top creators. I tried all the tools. I tracked what works on LinkedIn (and what’s just hype).
If you want to skip the expensive learning curve, this post is for you.
Let’s dive into the highlights from my personal playbook 👇 LinkedIn Isn’t Just a Platform, It’s an Inbound Lead Engine
But only if you:
Show up consistently
Speak up authentically
Stand out strategically
That means random posts whenever you feel inspired? Nope. That’s not enough.
The real game-changer?
Start with your WHY.
Before posting, commenting, or updating your headline, clarify your objectives.
What do you want to achieve on LinkedIn?
Choose Your Objective
Here are the 6 categories I see most professionals aiming for—and I’ve tested them all:
1. Authority & Thought Leadership
Build authority in your industry
Become known for your expertise
Get podcast invites and panel gigs
Contribute to LinkedIn articles or external publications
Be seen as the go-to expert on your topic
2. Audience Growth & Visibility
Grow your follower base (with people who actually engage)
Increase visibility with decision-makers
Expand reach with carousels, polls, and smart storytelling
Create content that gets saved and shared
Improve your Social Selling Index (SSI)
3. Lead Generation & Sales
Attract inbound leads from dream clients
Drive traffic to your offers, website, or funnel
Promote your products, services, or coaching
Grow your list with a freebie or lead magnet
Book more discovery calls with aligned prospects
4. Networking & Relationship Building
Build authentic relationships with collaborators and influencers
Connect with your target audience
Turn casual comments into real business conversations
Reconnect with former coworkers or mentors
5. Career Growth & Opportunities
Be seen by internal leadership
Position yourself for a promotion
Get noticed by recruiters
Make a smooth pivot into a new role or industry
6. Content & Community Building
Grow your newsletter subscriber list
Launch a content series that keeps people coming back
Build a values-aligned community
Get honest feedback and support from peers
Learn from the Right People
Here are a few standouts I follow and recommend:
Shanee Moret – Master of viral value. Her content delivers.
Will McTighe – Smart strategies and a creator-first mindset. Plus, he's genuinely kind.
Chris Donnelly – Breaks down the science of engagement. Legit pro.
Jasmin Alić – A voice for authentic branding and the power of strategic commenting.
Tools That Are Actually Worth It
(Trust me—I’ve tried all the shiny ones.)
SayWhat – AI ghostwriting that still sounds like you
Taplio – Great for content scheduling and analytics
AuthoredUp – High-converting templates = yes please
ChatGPT + Custom Prompts – Still my secret sauce for ideas & outlines
Formats That Get Results
Want more reach? Focus on formats that actually convert:
Text-only storytelling with killer hooks
Actionable carousels
Short-form listicles (3–5 points)
Personal wins + lessons learned
LinkedIn Lives (builds trust fast)
Newsletters (best for nurturing)
60–90 sec video snippets (great for connection)
But Here’s the #1 Most Important Lesson:
Before you use a single tool, template, or trend...
Get clear on:
Who do you want to reach
Why are you showing up
What success looks like
How you’ll measure it
And honestly? Have FUN.
Because if it feels like a chore, you won’t stick with it.If it feels like play, you’ll keep going—and that’s when the magic happens.
Pro Tip: Your first 2–3 lines of any post?
They make or break your content. Hook fast or scroll on.
Success on LinkedIn isn’t about copying what works for someone else.
It’s about:
Consistency
Value
Clarity
Connection
Test what works for you. Show up for your people. Make it fun.
And if LinkedIn still feels like a grind? Hire someone who loves this stuff to help you.
