Why 41% of Your LinkedIn Comments Are Invisible (And How to Fix It)

On the other side of this issue are founders who treat commenting as one of the highest ROI activities they do on LinkedIn right now. Not as engagement theater, but as borrowed distribution—a way to put themselves in front of other people's audiences, nurture their leads, and do it all without spending a penny on ads.

I built Contentin, and we track commenting activity across 5,500 users on the platform. Right now, we have about 250,000 comments and their analytics data in our database.

What that data reveals will change how you think about commenting entirely. Because most of what you've heard—"be consistent," "leave 50 comments a day," "add value"—is either too vague or misses the point entirely.

Watch the full breakdown above, or keep reading for the complete system.

The Ugly Truth: 41% of LinkedIn Comments Get Zero Engagement

Let's start with the reality check: four out of 10 comments left on LinkedIn get zero response.

Not "ignored"—zero. No likes, no replies, no reaction of any kind. They appear in the thread and are never interacted with. They might even get hidden and collapsed when LinkedIn shows "relevant comments."

That's 41% of comments in our dataset.

And the founders leaving them aren't bad writers. They're just doing it wrong in a specific way:

• Wrong type of comment
• Wrong type of post
• Wrong timing

The standard advice you get is: "Be consistent. Leave comments every day. Show up in other people's feeds."

What this advice doesn't tell you is that if you're doing it wrong, 40% of those 50 daily comments will have exactly the same impact as if you said nothing. So why leave them in the first place?

LinkedIn's 360 Brew Update Changed Everything

There's something more recent at play, too. LinkedIn's 360 Brew update now reads your commenting activity as part of your topic and audience fingerprint.

Who you engage with, what posts you respond to—it's all part of how LinkedIn classifies you and who it shows your content to.

So the posts you comment on aren't just a time investment. If they're wrong for your niche, they're diluting your fingerprint.

It's a bit stupid, but it's the way it is. Getting strategic about comments isn't optional anymore—it's part of how the algorithm reads you and part of your success strategy on LinkedIn.

Not All Posts Are Equal Targets (And the Data Proves It)

Here's why post selection matters more than you think:

Posts that accumulate 20 or more comments generate around 88 average profile views for the person who wrote them.

Posts with almost no comments generate about 2.

Your comment lives on that post. When you put a thoughtful comment on a post that gets traction, you're visible to everyone that post reaches. When you put the same comment on a post going nowhere, it goes nowhere with it.

This is the mistake most founders make: They leave good comments on quiet posts written by people they like, and nothing happens. The comment wasn't the problem. The post was the wrong vehicle for it.

What Makes a Post Worth Targeting?

A post is worth commenting on when:

• It's moving early — In the first 30-60 minutes, comments are appearing and people are sharing
• It's written by someone your ICP follows or is — Not random influencers, but people in your buyers' world
• The topic matters to your buyers — Not just something in your general world, but something your customers actually care about

You need a list of 20-30 (max 50) founders and voices in your ICP's space. Check those accounts in the morning. When one of them posts something that's gaining traction, that's your window.

Contentin makes this incredibly easy by building your own custom feed for those 20-30 profiles.

Real Example: 3x Profile Visits in 6 Weeks

One of our users tracked his comments deliberately for one quarter (3 months). Based on what he was already doing, he built a short list of 22 accounts that were actually effective for him—all in his ICP's world that tended to give him impressions and engagement more often than others.

He committed to showing up early on posts that were already moving from those 22 profiles.

Six weeks later, his profile visits from commenting activity had tripled.

Same time investment. Completely different result. The difference wasn't how much he commented—he was actually commenting less. It was where, when, why, and what.

What Top-Performing Comments Actually Look Like

Here's what I can tell you with confidence from 250,000 comments:

Not a single top-performing comment in the data was a simple agreement. Not one.

No "Great post." No "So true." No "Thanks for sharing."

Every comment that got real interaction—real likes, real replies, real threads—either:

• Pushed back
• Added something the author hadn't said
• Made one observation so sharp that people wanted to respond to it

That's not a style preference. That's what the data shows. Consistently across topics, industries, and languages, agreeable comments are invisible.

The Rule: Add a Layer, Don't Echo

Take one specific thing from the post—one claim, one sentence, one idea—and go one level deeper than the author did.

Not a summary of what they said, but something they didn't say.

Example: A founder on our platform left a comment on a post about hiring. The post was about finding people better than you. The comment was:

"The hard part isn't finding people better than you. It's not inserting yourself once you do."

12 words. 96 likes.

It was the observation the post was heading toward but never quite made. That's a layer.

Doing that five times outperforms doing 50 generic comments by far. Same time investment, a little more effort, way better results—for the algorithm, for your ICP, for everything.

Three Types of Comments That Consistently Perform

1. Grounded Pushback

Not hostile, just "I've seen the opposite. Here's why." Comments that disagree—done with substance and specificity—draw far more replies than comments that agree. Because they open a thread instead of closing one.

2. Data Adds

When a post makes a claim and your comment has a number—something real from your own experience or work—that makes the original claim more specific or challenges it. The comment becomes the most informative thing in the thread. That's how you build authority in someone else's audience.

3. The Missing Observation

The thing the post was building toward but didn't quite articulate. When you name it clearly, people respond.

The System: How to Make Commenting Consistent and High-ROI

Five comments a day scattered across whatever appears in your feed is not a system. It's productive procrastination. It's activity.

And activity with a 41% invisible rate is mostly wasted effort.

The system is smaller and more deliberate:

Step 1: Build Your List of 20-30 Accounts

Take your time with this. This isn't a living list—you'll iterate and optimize over time.

These are founders and voices in your ICP's world:

• People your buyers follow
• People who are your buyers
• Leads you're currently nurturing

Not big LinkedIn content creators that draw random crowds. Not your direct competitors. The people whose audiences overlap with yours.

Step 2: Figure Out When They Post and Show Up Early

The first hour of a post's life is the highest value window. This is still true in 2025, even though it's not as critical as it used to be—posts live a lot longer now and can travel for 2-3 days.

But LinkedIn still gives early engagement more weight in the algorithm. It's what signals the post is worth pushing to more people. Earlier comments mean more people see it, which means more people see you.

Pro tip: Check if the post is actively working or already burned out before commenting on older posts.

Step 3: Leave Fewer, Better Comments

Five targeted comments that actually say something will outperform 50 generic ones.

Not because of some algorithm trick, but because only one of those 50 will add a layer. The rest will disappear into the 41%.

Step 4: Make Your Comments Standalone Observations

The best comments read as standalone observations, not just responses.

Ask yourself: If someone sees your comment out of context—in a notification, in someone's feed—does it make sense? Does it say something worth stopping for? Does it make the person reading your comment want to read the actual post?

The comments that drive profile visits tend to read like posts in their own right—just more compact, more pointed, and not dependent on the original to make sense.

Stop Treating Comments as Engagement Theater

Here's the shift: Stop looking at commenting as engagement, a way to perform presence, to show up and be seen.

Instead, think about it differently.

Every comment is borrowed reach. You're putting something of yours in front of someone else's audience.

The only question is whether that something is worth stopping for.

Most comments aren't—not because the people leaving them can't write, but because they're saying what's easiest to say rather than what's actually worth saying. You do it quick.

The hard part is having a take. A take that takes longer than a like. But a take is the only thing that makes a comment worth stopping for.

Your Next Steps

Here's what to do tomorrow morning:

1. Build the list — 20 accounts, people in your ICP's world
2. Start checking them — See what's getting early traction
3. Leave 3-5 comments that add a layer — Not agreement, not generic value-adds, but sharp observations

This isn't about working harder. It's about being more strategic with the same time investment. Because 41% of your current effort is going nowhere. It's time to fix that.
