Can You React to Comments on LinkedIn? How and When To
Yes, you can react to comments on LinkedIn, not just posts. Here are the six reactions, how to add or remove one, and when to react instead of reply.

The short version
- Yes, you can react to comments on LinkedIn, not just posts. Hover over (desktop) or press and hold (mobile) the Like icon under a comment, then pick a reaction.
- LinkedIn offers six reactions: Like, Celebrate, Support, Love, Insightful, and Funny. Each one acknowledges a comment without you writing a full reply.
- A reaction is a one-tap signal; a reply adds text and keeps the thread alive, which does more for reach. Use reactions for acknowledgement, replies for conversation.
- To remove a reaction, tap the same reaction again. It disappears, and your network is no longer shown that you reacted.
- As the post author, reacting to comments is a fast, honest way to show you read them, so you can save full replies for the threads worth continuing.
React or reply? A simple rule
Reactions and replies are not interchangeable, and treating them as the same thing is where a lot of engagement gets wasted.
A reaction is a one-tap acknowledgement. It tells the commenter you saw them and adds a tiny icon to the thread. A reply adds your own text, keeps the post active longer, and can surface the conversation to more people. For the mechanics of writing replies that actually land, we walk through it in how to comment on LinkedIn posts.
Our rule of thumb: react to acknowledge, reply to converse. If a comment is a kind one-liner, a reaction is a perfectly polite response. If a comment asks a question, disagrees, or adds a point you can build on, that one deserves a written reply because it can turn into a real exchange.
Does the commenter know you reacted?
Yes. LinkedIn's Help documentation is clear that posts and comments you react to are shared with your network, and the person is informed of the reaction you chose. So when you tap Insightful under someone's comment, they can see both that you reacted and which reaction it was.
This is what makes a reaction more than a private bookmark. It is a small, visible act of recognition aimed at a specific person. For a busy author clearing a thread, that visibility is the whole point: a genuine reaction lands as "I read this and it mattered," which is often all a kind one-line comment was asking for in the first place.
Reacting as the author versus as a commenter
The two roles use reactions differently.
As the author of a post, reactions let you clear a busy comment section without going silent. You can react to the quick "congrats" and "love this" notes, then spend your typing energy on the handful of comments that opened a genuine conversation. That is a far better use of your time than either ignoring everyone or forcing a hollow "thank you!" under all forty comments.
As a commenter on someone else's post, reacting to other people's comments is a low-key way to show up in a thread you care about. React to a sharp point with Insightful and the person often notices. It is a smaller move than jumping in with your own comment, and sometimes it is the right size.
What reacting does for reach, and what it does not
Be honest about the limits here. A reaction is a light engagement signal. It nudges a thread a little, but it does not carry the weight of a comment, which adds text and keeps a post circulating. If your goal is visibility, a thoughtful comment beats a reaction almost every time, a point we make in should you reply to every LinkedIn comment.
So do not mistake a wall of reactions for engagement strategy. Reactions are the connective tissue between real comments, not a replacement for them. To undo one you added by accident, tap the same reaction again and it drops off, and your network stops being shown it.
How we handle reactions at Commenti
We build an assisted commenting tool, so people sometimes ask why we do not just auto-react to everything in sight. The honest answer is that a reaction from a tool, sprayed across a feed, is worth close to nothing and reads as exactly that. Reactions only mean something when a person actually chose one that fit.
That shapes how we think about the whole product. Commenti helps you write comments worth reading, with a daily cap and an approve step, because the leverage on LinkedIn is in the comment, not in a pile of automated Likes. A reaction is a nice acknowledgement you can add in a second by hand. The part that is genuinely hard, and genuinely valuable, is the comment underneath, and that is the part worth the effort.
Frequently asked questions
How do I react to a comment on LinkedIn?
Find the comment, then hover over the Like icon beneath it on desktop, or press and hold it on mobile. A row of reactions appears. Click or tap the one you want. Your reaction shows under the comment and is shared with your network.
What reactions can you use on LinkedIn?
LinkedIn currently offers six reactions: Like, Celebrate, Support, Love, Insightful, and Funny. They work the same on comments as on posts, so you can pick the one that fits, for example Insightful for a sharp point or Celebrate for good news.
Is reacting to a comment the same as replying?
No. A reaction is a single tap that acknowledges the comment and shows a small icon. A reply adds your own text under it and keeps the thread active longer. Reactions are quick recognition; replies build the actual conversation and reach.
Should you react to every comment on your post?
Reacting to most comments is a friendly, low-effort way to show you are present. But save written replies for comments that add a real point or question, since a reply does far more to keep the post visible than a reaction does.

Someone leaves a thoughtful comment on your post. You want to acknowledge it, but a full reply feels like too much for a one-line note of thanks. So the question comes up: can you react to comments on LinkedIn the same way you react to posts, or is the Like button only for the post itself?
You can. LinkedIn lets you react to any comment, not just the post at the top of the thread. And once you know the difference between a reaction and a reply, you can work a comment section far faster without ignoring anyone.
Yes, you can react to a comment
LinkedIn's reaction system applies to comments and posts alike. Under every comment sits a Like control. On desktop, hover over it and a small row of reaction icons pops up. On mobile, press and hold the same icon to bring up the row, then lift your finger over the one you want.
Per LinkedIn's Help documentation, reacting is shared with your network, so people can see the reaction you chose. That is worth remembering: a reaction is not private. It is a small public signal attached to your name, which is exactly why it can be useful.
The reactions and what each one signals
There are six reactions to choose from, and picking the right one adds a little meaning that a plain Like does not:
On a comment, Insightful and Celebrate do the most quiet work. Insightful rewards the person who added a real idea to your thread, and Celebrate fits a congratulations left under an announcement. You are matching the reaction to what the commenter did, not just tapping Like on autopilot.
