Short answer: yes. Buffer analyzed about 72,000 linkedin posts from nearly 25,000 accounts and found posts where the author replied to comments got about 30% more engagement. Around 83% of profiles did better when they replied. But only about 8% of posts in the sample had replies. So most people skip the easiest boost they have.

Does replying to comments on linkedin increase engagement?
You spend hours on your content. Hooks. Carousels. Posting times.
Then you post and move on. The comments sit there.
That's the part most people skip. And it might be the highest-return thing you can do on linkedin.
Buffer published the numbers in November 2025, based on an analysis by Julian Winternheimer. About 72,000 linkedin posts. Nearly 25,000 accounts. Posts where the author replied to comments got about 30% more engagement than posts where they stayed silent.
What did the Buffer study find?
The engagement numbers:
- Posts where the author replied: median of 32 engagements.
- Posts with no replies: median of 25 engagements.
- That's the roughly 30% lift.
How consistent it was:
- About 83% of profiles did better on posts where they replied.
- The analysis compared each account with itself over time. So it isn't just big accounts beating small ones.
How few people do it:
- Only about 5,600 of the 72,000 posts had replies from the author. That's around 8%.
- So more than 90% of posts in the sample got no reply from the person who wrote them.

Why does replying to comments work on linkedin?
linkedin wants real conversations in the feed. In March 2026 it said so directly: it's pushing out engagement pods, automated comments and engagement bait so real people and real conversations stand out.
When you reply to a comment, a few things happen at once:
- The post gets another comment.
- The conversation stays active longer.
- The person often replies back, and now it's a thread.
- linkedin sees a post where people are actually talking.
So why don't people do it? Because it doesn't feel like content. It feels like admin. You post, check the first likes, and start on tomorrow's post. The conversation you started gets left behind.
How much engagement are you leaving on the table?
Here's a simple example. The numbers are made up. The 30% is from the study.
You post 3 times a week. Each post gets 20 engagements. That's 12 posts and 240 engagements a month.
Now you reply to every real comment. With a 30% lift, that's 12 posts at 26 engagements. 312 a month.
That's 72 more engagements. No extra posts.
But the count isn't the point. Every comment is someone saying "this was relevant to me." When you reply, you start a conversation with that person. Some of them are buyers. These are warm conversations, not cold outreach.
What the data doesn't tell you
The analysis is clear about its limits. It calls the results directional.
- It doesn't prove cause. Posts that do well might just attract more comments, and so more replies. It could run both ways.
- The reply sample is small. About 5,600 of 72,000 posts.
- Comments are part of the engagement count. Replying adds comments, so some of the lift is built in.
Even so, the action is the same. Show up in your comment section.
How to reply to comments on linkedin: what to do now
This week Open your last 10 posts. Find the comments you never answered. Reply to them, even if they're a few days old. Ask a follow-up question.
This month Make replies part of posting. Block 15 minutes right after a post goes live. Check again 24 hours later. Aim to answer most real comments within a day. Not just "thanks". Add something.
This quarter Write posts that invite comments. Ask questions. Share half a framework and let people add to it. Track engagement before and after you start replying.
If you run a team of people posting (sales reps, execs, experts), track replies next to posting frequency. It matters as much.
The bigger picture: engagement is the new distribution
Posting and leaving is getting less effective. Conversation is winning.
Your competitors are probably still in "post and ghost" mode. They count posts. You can count conversations.
And the people commenting on your posts are telling you something. Some of them fit your ideal customer profile. If you can see who they are, you know which conversations to take further. More on that in what linkedin engagement signals tell you.
