The Commenting Strategy: LinkedIn's Most Underrated Growth Channel
Thoughtful comments on bigger accounts are the fastest way to grow from zero on LinkedIn. Here's the daily routine, what to write, and what to avoid.
When you have 200 followers, your posts are performed to an empty room. But comments? Comments run on other people's stages. A sharp comment under a 50,000-follower creator's post gets seen by thousands of people in your exact niche — for two minutes of writing. It's the highest-ROI activity in early LinkedIn growth, and almost everyone does it wrong.
Why comments punch above their weight
- Borrowed audiences. The creator built the crowd; a great comment lets you address it.
- Comments get ranked too. LinkedIn sorts comments by relevance — thoughtful ones with replies float to the top and stay visible for the post's entire life.
- Profile visits follow. People who like your comment click your name. If your profile converts and your recent posts are solid, a percentage follows.
- Relationships form. Comment meaningfully on someone's posts for three weeks and they know your name. That's networking that doesn't feel like networking.
The daily routine (20 minutes)
- Curate 10–15 accounts in your niche: a few big creators (50K+), several mid-size (5–50K), and a few peers. Big accounts give reach; mid-size give relationships; peers give allies who grow with you.
- Comment on 5–10 posts daily, ideally within the first hour of them posting (your comment rides the post's growth curve — same golden-hour logic as your own posts).
- Spend 2 minutes per comment, not 10 seconds. The quality bar is what makes this work at all.
What a great comment looks like
The formula: add something the post didn't have.
- Extend: "This matches what I saw managing 6 migrations — the step everyone skips is X, and it's exactly why Y happens."
- Respectfully counter: "Agree on most of this, but in early-stage teams I've found the opposite: …"
- Add a mini-story: a 3-line experience that illustrates (or complicates) their point
- Ask a sharp question: one that makes the creator think, not "what do you mean?"
A great comment is a micro-post: it demonstrates your expertise to an audience that hasn't met you yet. Many strong comments can later be expanded into full posts — it's a free idea-validation loop for your content calendar.
What kills the strategy
- "Great post! 🔥" — invisible at best, spammy at worst. Zero value added, zero attention earned.
- Self-promotion in comments ("I wrote about this — link!") — reads as parasitic; the audience and creator both notice.
- Auto-commenting tools — AI-generated generic comments are easily spotted, damage your reputation, and violate LinkedIn's automation rules (what's safe, what's bannable). Comments are the one thing you should never automate.
- Commenting only on mega-accounts — thousands compete for attention there; mid-size accounts are where comments get seen and remembered.
Comments + content: the complete engine
Commenting alone grows your name; content converts that name into a following. The loop: comments make people visit your profile → your posts make them follow → your posts' own comment sections become communities. Skipping either half stalls the flywheel.
The balanced setup for busy professionals: automate the content leg — InGrow researches, drafts in your voice, and publishes on schedule — and spend your live human minutes on comments and replies, where authenticity can't be faked. Twenty minutes of daily commenting plus an automated 3-post week is a complete growth system in under 30 minutes a day.
Key takeaways
- Comments borrow bigger audiences — the fastest channel from 0 to 1,000 followers
- Formula: add what the post didn't have (extend, counter, story, sharp question)
- Never automate comments; always automate-or-batch content
- The flywheel: comments → profile visits → follows → your own comment community
