How to grow faster on LinkedIn in 2025

Most people treat LinkedIn like a digital billboard.

They post a random "inspirational" nugget, hope for a few likes, and then sit back, waiting for some invisible LinkedIn fairy to make them go viral.

Spoiler: that's not how this works.

The secret sauce to LinkedIn growth isn’t just in the posts.

It’s in the comments.

Yep, those tiny, often overlooked conversations hiding below someone else’s spotlight.

Here’s a breakdown of how to turn commenting into your LinkedIn growth superpower:

1. Why comment?

Think of comments as mini billboards that pop up everywhere.

Each comment is a chance to build visibility and credibility because people notice smart, engaging comments even if you’re not the original poster.

Consistent commenting strengthens your network and builds familiarity with the people you want to know.

It also lets you share expertise without the pressure of creating a masterpiece post.

2. How to comment?

Not all comments are created equal.

A simple “Great post” isn’t going to get anyone’s attention.

Instead, support the creator by acknowledging the effort they put into the post.

Add a clever or funny take if it fits the conversation.

Humor is rare on LinkedIn, which makes it memorable when used appropriately.

You can also provide valuable insights by sharing quick, actionable thoughts or expanding on the original idea.

3. When to comment?

You don’t want your comment buried under a pile of others, so timing matters.

Engage before and after you post because this puts you in conversation mode, and LinkedIn rewards activity.

Leave comments in intervals instead of a comment binge by sprinkling them throughout your day.

Strike early because the first 60 minutes after a post goes live are prime commenting real estate.

4. Whose posts to target?

Not every post deserves your thoughtful input, so be strategic.

Spend 20 percent of your commenting time engaging with prospects or leads.

Commenting on their posts keeps you on their radar without sliding awkwardly into their DMs.

Dedicate 50 percent of your time to peers in your network to support your colleagues and collaborators while deepening your connections.

Use the remaining 30 percent to comment on posts from top creators in your field because their posts often go viral and expose you to a wider audience.

5. Avoid these traps

If you want to stand out, avoid AI-generated comments because people can tell.

Be human, even if it takes more time.

Avoid empty compliments like “Great post” because they add no value to the conversation.

Don’t make the comment all about you.

Avoid hijacking the post to promote yourself and instead focus on adding value first.

6. Bonus hacks

Pin your own additional comments under your posts to add more value to the conversation and trigger even more engagement.

Reply to comments for an hour after posting because it boosts visibility and builds relationships.

If you write a great comment elsewhere, expand it into a full post later.

The big takeaway:

Posts may get attention, but comments build connections.

So, next time you’re on LinkedIn, don’t just scroll mindlessly or hit like.

Jump into the conversation, drop a thoughtful comment, and watch the magic unfold.

Because in 2025, the ones who comment are the ones who win.
