> **The gist.** An effective LinkedIn commenting routine fits in **15-30 minutes a day**, in the morning on weekdays. The recipe, backed by our data: aim for **20-50 comments/day** (the reach/time sweet spot), post them **early** on your targets' posts, and **target the right creators**. At ~29s per comment measured with LinkHub, **30 comments ≈ 15 min**. This guide gives the step-by-step routine — with one honesty rule: **quality and targeting always beat raw volume.**

## Key takeaways

- **Aim for 20-50 comments/day.** That's the reach/time sweet spot: strong total reach (~**4,587 impressions/day** on the 20-49 bucket) without diminishing returns. *(LinkHub, user-day basis — see [how many per day](/en/blog/combien-de-commentaires-par-jour-linkedin))*
- **Time is no longer the blocker.** At **~29s per comment** measured with LinkHub (n = 44,523), **30 comments ≈ ~15 min** and 50 ≈ ~25 min. The 20-50/day routine becomes sustainable. *(LinkHub)*
- **Mornings on weekdays.** The morning window (≈ 7am-2pm Paris time), Tuesday to Thursday, concentrates the best visibility. *(LinkHub + Buffer/Hootsuite — see [best hours](/en/blog/meilleures-heures-pour-commenter-linkedin))*
- **Comment early.** Within the **first half hour** of a post: 391 average impressions versus 104 after 24h (~3.8x). *([when to comment](/en/blog/quand-commenter-sur-linkedin))*
- **Target the right creators.** Commenting on a top-10% creator earns ~3.4x the median — same effort, 3 to 10x more reach. *([who to comment on](/en/blog/sur-qui-commenter-linkedin))*
- **Honesty.** These figures are our first-party data + dated third-party estimates. And the real rule stays: **quality and targeting > raw volume.**

## 1. Set your target: 20-50 comments/day

Before building a routine, set a realistic, grounded goal. On the LinkHub database, **total reach climbs without interruption** with volume — from **581 impressions/day** (1-7 comments) to **11,737/day** (100+) — but the right trade-off isn't "the maximum," it's **the best reach/time ratio**.

| Comments/day | Impressions per comment | Total reach/day |
|---|---|---|
| 1-7 | 268 | 581 |
| 8-19 | 215 | 2,595 |
| **20-49** | **153** | **4,587** |
| 50-99 | 145 | 9,901 |

The **20-49/day** bucket is the sweet spot: strong total reach (~**4,587 impressions/day**, ~8x the low bucket), still-solid per-comment (153) and sustainable time. That's your routine target. The full method and limits are in our study [how many comments per day on LinkedIn](/en/blog/combien-de-commentaires-par-jour-linkedin).

**Routine goal:** aim for **25-30 quality comments per day** to start — comfortably inside the sweet spot, under the platform safety threshold (commonly reported ~80-100/day for an established account, *third-party thresholds to confirm*), and doable in under 30 min.

## 2. Pick your slot: mornings on weekdays

Consistency beats intensity. A daily routine **at a fixed time** is more effective than a once-a-week marathon — it's also the practitioners' consensus, who describe [20-minute](https://medium.com/marketing-strategy-guide/the-20-minute-linkedin-routine-that-builds-momentum-daily-c56afd9b0be9) routines built on consistency ([Fizza Batool, 2025](https://medium.com/marketing-strategy-guide/the-20-minute-linkedin-routine-that-builds-momentum-daily-c56afd9b0be9)).

The best moment, per our data:

- **Days**: Tuesday to Thursday, the median impressions are most stable; weekends are less reliable.
- **Time**: the morning window (≈ **7am-2pm Paris time**) concentrates the strongest visibility; it declines in the afternoon and evening.

So block **15-25 min in the morning** — for example when you get to your desk, coffee in hand. The hour-by-hour detail is in our study [best hours to comment on LinkedIn](/en/blog/meilleures-heures-pour-commenter-linkedin).

## 3. Open your personalized feeds (not the native feed)

This is the step that saves the most time. Scrolling the LinkedIn feed at random is a guaranteed way to waste 20 minutes on off-target posts. Instead, open a view that **gathers only your targets' posts**, sorted newest first.

That's exactly the role of [personalized feeds](/en/features/feeds-personnalises): you bring together your prospects and the key creators in your niche, and you see their posts **as soon as they go live** — no noise, no algorithm deciding for you. At a glance, you have your morning target list, sorted by freshness. *(To refine the sort, see [finding the right posts to comment on](/en/blog/trouver-bons-posts-commenter-linkedin).)*

The point: commenting **early**. A post gets most of its reach in its first hour, and our data confirms it for comments — posting your comment within the **first half hour** earns **391 average impressions** versus 104 after 24h, i.e. **~3.8x**. See the study [when to comment on LinkedIn](/en/blog/quand-commenter-sur-linkedin). A feed sorted by freshness naturally places you in that golden window.

## 4. Comment early and well: ~25-30 comments in 15-25 min

You have your list of fresh posts. Now place your comments. This is where time-per-comment makes all the difference.

Commenting manually in a thoughtful way easily takes 2 to 3 minutes: read the post, find an angle, write. At that pace, 30 comments = **over an hour** — no one keeps that up daily. On our database, a comment takes **~29 seconds** measured (n = 44,523), thanks to [personalized AI comments](/en/features/ia-commentaires-personnalises): a relevant suggestion ready to approve, that **you review and edit** before sending. At that cost, **30 comments ≈ 15 min** and **50 comments ≈ 25 min**.

The concrete morning flow:

- **Go through your feeds** from the top (freshest posts) down.
- **For each relevant post**, post a comment of **15-40 words** that [adds an angle](/en/blog/ecrire-bon-commentaire-linkedin) — not a "Great post!". A comment that brings an idea gets replies → conversational effect, more reach.
- **Edit the AI suggestion**: a tweak personalizes the tone and improves performance.
- **Stop at ~25-30 comments** or when your slot is up. You're in the sweet spot.

Result: **~25-30 quality comments, early, on the right posts, in 15-25 min.** That's the routine.

## 5. Target the right creators (the most underrated lever)

Volume pays — but commenting on **the right profiles** pays far more. For the same effort, the target changes everything: across 4,861 creators, commenting on a **top-10%** creator earns **~3.4x the median** (124 vs 36 impressions), a **top-1%, ~10x** (357).

In other words, the **same ~29s comment** earns 3 to 10x more depending on **who** you comment on. It's the most profitable lever in your routine — see the study [who to comment on, on LinkedIn](/en/blog/sur-qui-commenter-linkedin).

To build your target list:

- **Comment on the big accounts in your niche**: your comment gets exposed to their audience.
- **Prioritize creators whose audience overlaps your [ICP](/en/blog/icp-commentaire-linkedin)**: reach converts into prospects, not just views.
- **Let AI help you choose.** The [AI profile recommendation](/en/features/ia-recommandation-profils) computes your ICP and proposes, among 100,000+ profiles, the best-ROI creators — which you then gather into your [personalized feeds](/en/features/feeds-personnalises).

## Do you really have to comment every day?

Yes — **consistency** is the engine. A daily 15-30 min routine beats an intensive weekly session, because visibility builds by accumulation and commenting early means being present when posts go out. Practitioners converge: routines of [15](https://blog.linkmate.io/how-to-increase-linkedin-engagement-without-spending-hours-daily-15-minute-strategy/) to 20 minutes, **kept every working day**, are enough to build a presence ([Linkmate, 2025](https://blog.linkmate.io/how-to-increase-linkedin-engagement-without-spending-hours-daily-15-minute-strategy/)).

But let's be honest about one thing: **volume is not an end in itself.** Hitting 30 generic comments a day is counterproductive — for your reach and your reputation alike. The right goal is **30 relevant comments, on the right posts, at the right time**. Quality and targeting always beat the counter. A well-equipped routine (targeted feeds + AI suggestions approved by you) is precisely what lets you sustain the volume **without sacrificing** quality — that's the whole point.
