My Experiment to Find the Best Days to Post on LinkedIn
No Magic, Just Data 🔮
TL;DR
I ran LinkedIn like a lab experiment—and the data showed some 👻 spooky surprises about when to post.
Introduction
As a scientist, I ❤️ experiments. We set up a hypothesis, test it, measure the results, and see what holds up.
So when I wanted to know the best days to post on LinkedIn, I skipped the “gurus” and did what felt natural: I ran my own experiment. No magic formulas 🔮. No spooky algorithms. Just 3 months of testing.
The Hypothesis
We’ve all heard it: there’s a golden day and time—Tuesday mornings, Wednesday afternoons, you name it.
But I wasn’t convinced. For me, LinkedIn isn’t run on spells or secret formulas. If there’s a “best,” it should show up in the data—just like any experiment.
The Setup
For 3 months, I posted across all weekdays (no weekends—because let’s be honest, I don’t want you scrolling LinkedIn on a Saturday).
⏰ Times tested: 9:45 AM and 1:45 PM
📄 Formats: all of them—videos, carousels, text posts, and polls.
📊 Metrics tracked: impressions and engagement (comments, reactions, shares).
Think of it like pipetting into every well of a plate—covering all variables, waiting to see which one lights up.
The Spooky Metrics
Some posts took off instantly. Others looked haunted—silent, lifeless, buried in the LinkedIn graveyard. Ironically, those were the ones I expected to perform best.
And then there were the tricksters: flat at first, only to rise from the dead 🧟♂️ 48 hours later with a spike in engagement.
The Results
After 3 months, 🔍 clear patterns emerged:
Best days: Tuesday, Wednesday, and Friday consistently outperformed Monday and Thursday.
Morning beats afternoon. 9:45 AM posts got more impressions and more regular engagement than 1:45 PM.
Stories win. Personal stories carried more weight than the format itself. A good story outperformed any carousel, video, or text post.
Double-Checking the Data
Like any experiment, one round of results isn’t enough—you run replicates to see if the trend holds.
Since those first 3 months, I’ve been checking the data at the end of each month to see if the pattern holds.
And here’s what I’ve learned: the timing (9:45 AM) has stayed steady, but the days can shift. Just last month, the top performers were Tuesday, Wednesday, and Friday.
LinkedIn, like science, is never static. The algorithm changes. People’s habits shift. Your audience evolves. The only way to stay sharp is to keep measuring.
The Takeaway
There’s no one-size-fits-all “best day.” The trick is in running your own experiment.
Right now for me, Tuesday, Wednesday, and Friday mornings are the sweet spot. For you, it might be different. But the process—hypothesis, test, measure, adjust—always works. 😉
Final Thought
Forget secret formulas. The real trick is building a posting rhythm that feels sustainable and backed by data.

Thank you for sharing this. These are very useful insights - I always wondered about the best time to post something on LinkedIn, and in the past I felt that some of my posts did not get a lot of visibility because I posted them at the wrong time.
