Your LinkedIn Comments Are Doing More Work Than Your Posts

A lot of people are convinced their LinkedIn problem is their posts. The posts aren't bad. They just land in front of the same few hundred people every time, get a polite trickle of likes, and disappear by Wednesday.

The fix usually isn't a better hook or a new posting schedule. It's twenty minutes a day spent writing comments on other people's posts. Not "Great insight!" comments. Real ones, the kind that take a position or add something the author left out.

If you're stuck at the same reach month after month, I think your comments are the cheapest fix you're not using. Here's how I'd approach it.

Why comments travel further than you'd expect

When you post, your words go out to your network first. If your network is small, or mostly people who don't care about your topic, that's where it stops.

When you leave a good comment on a post by someone with 40,000 followers, your words sit underneath their post for as long as people keep reading it. Their audience sees your name, your headline, and whatever you said. Some of them click through. A few of them follow you or send a connection request.

That's borrowed attention, and it's honestly the fastest way I know to get in front of people who don't know you yet. You don't need permission, you don't need an ad budget, and you don't need to have a big following yourself.

The catch is that most comments are invisible. "So true!" and "Thanks for sharing" don't get read. They get scrolled past. The comment has to be good enough that someone stops on it.

What a comment worth reading actually looks like

I'd break a useful comment into one of four types. You only need one per comment.

Add a missing piece. The author made a point; you add the bit they skipped. If someone writes about cold outreach and says "personalise your first line," you might add that in your experience the second line matters more, because that's where people decide whether it's a sales pitch.

Disagree, politely and specifically. This is the one people avoid, and it's the one that gets the most replies. You don't have to be combative. "I'd push back on the 3-posts-a-week number. Posting less often means each post gets more time and attention from you" is a disagreement people want to respond to.

Share a small, specific story. Not your life story. Two or three sentences about something that happened to you that backs up or complicates the post. Specific numbers and names of tools help a lot here.

Ask a question the author will want to answer. Not "What do you think?" Something narrow, like "Did this hold up when you tried it with enterprise buyers, or only with founders?"

Notice what's missing from that list: compliments. A compliment is fine as a first line, but if that's the whole comment, it's doing nothing for you.

A rough daily routine that doesn't eat your morning

I don't think you need an hour a day. Something like this is enough:

1. Keep a short list of 15 to 25 people whose posts reliably show up with real discussion underneath. Mix in a few big names and a lot of mid-sized accounts in your niche, people with 5,000 to 30,000 followers. The mid-sized ones are where your comment actually gets noticed and replied to.
2. Check their recent posts once a day, ideally within the first hour or two after they go up. Early comments sit near the top and get seen by more people. A brilliant comment on a three-day-old post is mostly talking to nobody.
3. Write three to five real comments. Not twenty. Three thoughtful comments beat twenty throwaway ones, and they're less likely to make you look like you're farming engagement.
4. Reply when people reply to you. This is where conversations turn into DMs, and DMs are where working relationships start.

Track two numbers while you do this: profile views and connection requests from people you've never interacted with. Notice which ones mention a specific comment rather than a post. That tells you whether the routine is working for you, better than any general advice can.

The mistakes that make commenting backfire

A few things that undo the effort.

Commenting like a bot. If every comment you leave starts with "Love this!" and ends with an emoji, people notice. The same goes for comments that are obviously AI-generated, the ones with three tidy bullet points and a summary line. They read as filler, and filler on someone else's post is a bit rude.

Pitching in the comments. Nobody wants to see "We actually help with this, DM me" under a thoughtful post. It's the fastest way to get ignored or quietly muted. Let the profile do the selling. If the comment's good, people will click.

Writing essays. A comment that's longer than the post gets skipped. Two to five sentences is usually plenty. If you've got more to say, that's a sign it should be your own post, and you can mention the original author when you write it.

Only commenting on the famous accounts. A comment on a post with 2,000 other comments is a lottery ticket. A comment on a post with 25 comments gets read by the author and probably gets a reply. Those replies build relationships, and relationships are the real point.

Being nice to everyone about everything. If you agree with every post you comment on, you don't have a point of view, and people follow points of view. Pick your spots, but don't be afraid to disagree.

How commenting feeds your own posts

This is the part people don't expect. Commenting every day can make your own posts better.

When you write three comments a day, you find out quickly which ideas you have strong opinions on. Some comments get ten replies and a long thread. Others go nowhere. The ones that sparked a thread are almost always worth turning into a full post, because you've already tested the idea in public.

Keep a running note of comments that got traction. When you sit down to write a post and you're out of ideas, open that note first. A comment that already started a conversation is often the strongest starting point for a post.

It also means your own posts land on warmer ground. When the people you've been talking with in the comments see your post in their feed, they recognise your name. They're more likely to stop, read, and respond, and early responses are what push a post out beyond your first circle.

Where tools help and where they don't

I'm not against using tools here. Keeping a list of accounts, getting a nudge when one of them posts, and tracking which of your comments turned into conversations are all things software is good at.

What I'd be careful with is letting a tool write the comment for you wholesale. The whole value of a comment is that it's you, reacting to a specific thing a specific person said. If you use AI at all, use it the way you'd use a colleague: to sanity-check a draft or help you tighten a clumsy sentence. Then make sure the final version sounds like something you'd actually say out loud. If it doesn't, rewrite it.

That's the same rule I'd apply to posts, honestly. The tool should save you time on the boring parts, so you have more time for the bit only you can do.

Start smaller than you think

If you take one thing from this, make it this: for the next two weeks, leave three real comments a day on posts in your niche, and don't post anything new unless you really want to. Watch your profile views and connection requests.

I'd bet you see more movement from that than from your last month of posts. And you'll come out of it with a list of ideas you already know people care about, plus a handful of people who now know who you are. That's a much better place to start posting from than shouting into the same quiet feed.
