A good LinkedIn comment picks one specific detail from the post, adds something of your own (an experience, a number, a different angle) and, if you're curious, asks one real question. Two or three sentences, roughly 150 to 400 characters, is the sweet spot. LinkedIn caps comments at 1,250 characters. Skip “Great post”, skip restating the post, and match the tone of the room.
Most comments on LinkedIn are invisible. Not hidden, just forgettable: “Congrats!”, “So true!”, “Thanks for sharing”. The author skims past them, and so does everyone else reading the thread.
The ones that get replies, profile visits and the occasional DM look different. They prove you read the post. We build a tool that drafts LinkedIn comments, so we've looked at a lot of them, good and bad. Here's what the good ones have in common, followed by 40 examples sorted by the kind of post you're replying to.
What makes a LinkedIn comment worth reading?
Think of it as anchor, add, ask. You don't need all three every time, and a comment that follows the recipe too neatly starts to sound like a recipe. But when a comment falls flat, it's usually missing one of them.
The anchor is one specific thing from the post. A number from the chart, a phrase the author used, the city they moved to. It tells the author you've read past the first line, which already puts you ahead of most of the thread.
The add is yours. Something that happened to you, a result from your own work, a place where you'd push back. It's what makes people click your name, because it shows how you think.
The ask is optional, and it has to be real. “What are your thoughts?” isn't a question, it's filler. “Was that the trial ending, or the point where the onboarding emails stop?” is a question the author can actually answer, and authors love answering those.
Great insights! Retention is so important. Thanks for sharing, what are your thoughts on the future of SaaS?
The drop in week 3 is the interesting bit. Is that the trial ending, or the point where the onboarding emails stop?

40 LinkedIn comment examples by type of post
Steal the shape, not the words. A copied comment is just a template with extra steps, and your network will notice when the same line shows up under three posts. Each set below covers a post type you'll see in your feed this week.
New job or promotion (4 examples)
The default here is “Congrats!” and a party emoji, so anything specific stands out immediately. Mention the role, the company, or the road it took to get there.
Eight months of searching and you kept posting the whole way. Congrats, they hired someone who doesn't quit.
Head of Partnerships at Lumen, that's a big jump from running two accounts solo. What made you say yes to this one?
Ha, I remember you pitching exactly this kind of team at that meetup in March. Congrats, Priya, go build it.
Promoted after the reorg everyone said would stall careers. Nice. Did the new scope come with a new team too?
Work anniversaries, funding and awards (4 examples)
Milestone posts collect dozens of identical congratulations. A comment that names what the milestone actually means gets read.
Ten years at one company is rare now. What's the one thing you'd tell yourself in year one?
A $4M seed in this market is a real signal. Curious whether investors pushed harder on retention or on the sales motion.
Congrats on the award. The case study about cutting onboarding to one call is the part I shared with my team.
Five years, and the product still looks like it was built by people who use it. That's harder than it sounds.
Product or feature launches (4 examples)
Founders read every launch comment. The best ones show you tried it, or ask the question a buyer would ask.
Tried it this morning on our messy CSV and it caught two duplicates our CRM missed. Is the API coming soon?
Love that you shipped the boring feature first. Bulk edit saves more hours than any AI button.
Congrats on the launch. Quick one: does the Zapier step work on the free plan, or only on paid?
The demo video is 40 seconds and I understood the whole product. More launches should do that.
An opinion you agree with (4 examples)
“So true!” adds nothing. Agreement is worth posting when it comes with evidence the author didn't have.
Agree, and I'd add one thing. Our best quarter came right after we cut the sequence from seven touches to three.
This matches what we saw hiring SDRs. The ones who asked the best questions in the interview ramped fastest.
Saving this. The line about writing the email you'd want to receive is going on a sticky note.
Yes. We stopped sending decks before calls last year and our show rate went up, not down.
An opinion you disagree with (4 examples)
Respectful pushback is the most underused comment on LinkedIn, and often the most read. Keep it about the idea, give your context, and leave room for the author to be right in theirs.
I see it a bit differently. Cold calling still works in our market (industrial supply), mostly because nobody else bothers anymore.
Fair point for B2B SaaS. In agencies I've found the opposite: clients want the long proposal, even if they skim it.
Partly agree. Remote works for senior folks, but our juniors learned twice as fast in the months we were in the office.
I'd push back gently on the never discount rule. A one time discount in exchange for a case study has paid for itself every time for us.
A chart, report or data post (4 examples)
Data posts are where comment tools fail most, because many of them can't see the image. Talk about what the chart shows, not about “great insights”.
The drop in week 3 is the interesting bit. Is that the trial ending, or the point where the onboarding emails stop?
40% from one channel is a lot of eggs in one basket. Have you tested what happens to pipeline if it dries up?
Bookmarking the chart. Would love the same split by company size if you ever have it.
Surprised email beats LinkedIn here. Is that counting replies or booked meetings?
A personal story or a failure (4 examples)
Vulnerable posts attract advice nobody asked for. What the author usually wants is to know it landed.
Thanks for writing the part most people leave out, the six months before it worked.
Shutting down something you built takes more nerve than starting it. Rooting for whatever comes next.
The bit about telling the team on a Friday hit home. We did the same, and I still think about it.
Most useful post I've read this week, because it's about what didn't work.
Layoffs, illness and other hard news (4 examples)
Shorter is kinder. Don't ask questions, don't make it about you, and only offer help you'll actually give. If you don't know the person, it's fine to just react and move on.
Sorry, Marco. If you're looking at ops roles in Berlin, I'm happy to send a couple of intros. Just DM me.
Thinking of you and your family.
That's a tough week. Your team was lucky to have someone who'd write a post like this on the way out.
Sending you strength. No need to reply.
Hiring posts and people open to work (4 examples)
Comments push posts to more people, which is why job seekers ask for them. A comment with a real endorsement or a useful question helps far more than a bare boost.
Sharing with two people I know who'd be great for this. Is it open to candidates in Lisbon?
One of the best account managers I've worked with. If you're hiring for customer success in fintech, talk to Dana.
Clear job post with the salary range up front. More of these, please.
Commenting so more people see this. Ana rebuilt our onboarding from scratch and cut time to value in half.
Replying to comments on your own post (4 examples)
Your own comment section is the most valuable thread you'll ever reply in. Answering keeps the conversation going and brings the commenter back.
Good question. We tested both, and the shorter version won by a mile, mostly on mobile.
Ha, fair. Three steps is still one step too many for some reps.
Great addition, I hadn't thought about renewals. Mind if I quote you in a follow up post?
Thanks, Sam. Your comment last week is what made me write this one.
Which LinkedIn comments should you stop writing?
Some comments do worse than nothing. Since July 2026, LinkedIn members can flag a comment as “Seems like AI slop”, and these are the patterns most likely to earn the flag.
| Comment | Why it hurts | Try instead |
|---|---|---|
| “Great post, thanks for sharing!” | Proves you didn't read it; reads as automated | Quote the line that stuck with you |
| A paraphrase of the post | The author already said it, better | Your own example or number |
| “Agreed! 💯🔥🚀” | Emoji instead of a thought | One sentence on why you agree |
| “CFBR” | Helps reach slightly, says nothing about you | A real endorsement or a useful question |
| A pitch for your product | Hijacks the author's post; often reported | Comment on the topic, let people find you |
| Four paragraphs | Longer than the post, rarely read | Two or three sentences |
| “What are your thoughts?” | They shared their thoughts. That's the post | A specific question they can answer |
How long should a LinkedIn comment be?
Shorter than you think. LinkedIn caps comments at 1,250 characters, which AuthoredUp confirmed in testing in March 2026. LinkedIn doesn't publish the number itself and some guides quote up to 1,750, so if you're near the edge, LinkedIn's comment box will tell you. Spaces, line breaks and emoji all count.
| Length | Roughly | Good for |
|---|---|---|
| One line | Under 100 characters | Hard news, congrats to someone you know well, a quick reply on your own post |
| Two or three sentences | 150 to 400 characters | Almost everything: launches, opinions, data posts, milestones |
| A short paragraph | 400 to 800 characters | When you're adding a real story or result the author will want to hear |
| Near the limit | 800 to 1,250 characters | Rarely. If you have that much to say, it might be your own post |
On mobile, where most people read LinkedIn, a 400 character comment is already six or seven lines. Anything longer gets skimmed.
What are impressions on LinkedIn comments?
It's the small eye icon with a number under comments you've written. LinkedIn rolled it out in 2025, and only you can see it on your own comments (admins see it on comments made as their page). It counts every view, so the same person scrolling past twice counts as two, and your own views count too.
Is it useful? A little. The number isn't in your analytics dashboard and there's no breakdown by who saw it, so it won't tell you much on its own. Where it helps is comparison. Open your activity tab and look at which comments pulled thousands of impressions and which pulled forty. Usually the big ones were early on a post that took off, and specific enough that people stopped to read.
Pinned comments, CFBR and other things people ask about
Can you pin a comment on LinkedIn? Yes, on your own posts. Open the three dots on the comment and pick “Pin comment”. It moves to the top with its replies and gets a Pinned label, and you can unpin or swap it any time. Authors often pin a comment with a link, since links in the post itself are widely believed to get less reach.
What does CFBR mean? “Commenting for better reach.” People leave it under job search posts and hiring posts because every comment nudges the post to more people. It's a kind gesture, honestly. The problem is that it says nothing, so if you're going to boost someone, add one line about why they're worth hiring.
When should you comment? Early helps. A post gets most of its views in its first day, and comments near the top of a thread get read more than comment number 200. That said, a great comment on an old post can still start a conversation with the author, who gets notified either way.
Should you tag the author? On their own post they're notified anyway, so tagging isn't required. It does make a comment feel addressed to a person instead of the room, and in long threads it makes sure they see your reply.
Can you use AI to write LinkedIn comments?
Yes, as long as the result sounds like you and says something specific. LinkedIn's product chief said in July 2026 that people who use AI to refine their thoughts should keep doing so. What gets flagged is the generic output: the restated post, the “not X, it's Y” line, praise for a chart the tool never looked at.
The difference comes down to three things. Does the tool read the whole post, including images and carousels? Does it write in your voice, from your own examples, rather than a house style? And do you read and edit it before it goes out? If all three are yes, nobody can tell, because there's nothing generic left to notice.
It reads the whole post, images included, tags the author for real and waits for you to press Post. 50 drafts free, no signup.
FAQ
What is a good comment to leave on a LinkedIn post?
One that mentions a specific detail from the post, adds your own experience or angle, and asks a real question if you have one. Two or three sentences is usually enough. Skip “Great post”, and don't paraphrase the author.
What is the character limit for a LinkedIn comment?
1,250 characters, including spaces, line breaks and emoji. LinkedIn doesn't publish it officially, but tools like AuthoredUp confirmed it in testing in 2026. Most good comments use 150 to 400.
What should I comment on a congratulations post on LinkedIn?
Name what the person actually achieved instead of writing “Congrats!”. Mention the role or the company, the road it took, or ask what made them say yes. For example: “Head of Partnerships at Lumen, that's a big jump from running two accounts solo. What made you say yes?”
What are impressions on LinkedIn comments?
They're the number of times your comment was viewed, shown with an eye icon under comments you wrote. Only you can see it. Repeat views and your own views count, and the number doesn't appear in your analytics dashboard.
What does CFBR mean on LinkedIn?
“Commenting for better reach.” People write it to push a post, often a job search or hiring post, to more feeds. It works a little, but a comment that says why the person is worth hiring helps them far more.
Do comments on other people's posts help your own LinkedIn reach?
They help your visibility more than your post reach. A good comment on a popular post puts your name and headline in front of that author's audience, and people click through to profiles from comments they found useful.
Can you edit a LinkedIn comment after posting?
Yes. Open the three dots on your comment and choose Edit. LinkedIn marks it as edited, so fixing a typo is fine, but rewriting what people already replied to can confuse the thread.
Checked on 12 October 2026. The 1,250 character limit is from AuthoredUp's March 2026 testing; comment impressions and pinned comments as described in LinkedIn's rollouts covered by Social Media Today. All 40 examples were written for this article; names and companies in them are made up.
