> **The idea, in one sentence.** In an active job search, applying isn't enough: your application drowns in the pile. Commenting gets you **noticed now** by recruiters and hiring managers — you become a familiar face **before** your application lands on their desk, and you tap the hidden job market. This guide gives the method, examples, and is backed by our first-party LinkHub data. Third-party figures are estimates from cited, dated studies. No invented numbers.

## Key takeaways

- **Your "client" is the recruiters and hiring managers** at the companies you target — not prospects who buy. Your comment ICP = **who to comment under so they spot you**. *(see [the ICP of a comment](/en/blog/icp-commentaire-linkedin))*
- **You're in an ACTIVE search, not long-term building.** Unlike a student sowing for later, you target the decision-makers of open roles now. Be more surgical, faster.
- **The hidden job market is huge**: a large share of roles is filled through networking rather than cold applications ([LinkedIn, 2025](https://business.linkedin.com/content/dam/me/business/en-us/talent-solutions/resources/pdfs/future-of-recruiting-2025-stff.pdf)). Commenting is how you enter that network.
- **A comment is seen ~179 times on average** (n=657,722): placed under the right host, it puts you in front of the right people.
- **The right host changes everything**: a top 10% in your target earns **~3.4x more** than the median. *(see [who to comment on](/en/blog/sur-qui-commenter-linkedin))*
- **The goal: turn visibility into a warmed application.** A recruiter who already knows you opens your CV differently.

## 1. Why applying isn't enough (and where commenting changes everything)

The job-search reflex is to **apply** — a lot, fast. But a cold application drowns: you're one line among hundreds, never seen by the hiring manager. Meanwhile, a large share of roles is filled **through networking and referral**, not the CV pile ([LinkedIn, Future of Recruiting 2025](https://business.linkedin.com/content/dam/me/business/en-us/talent-solutions/resources/pdfs/future-of-recruiting-2025-stff.pdf)). That's the hidden job market — and it's vast.

Commenting gets you into that network **through the door of visibility**. When you comment usefully on a post by a recruiter, a manager or a creator in your sector, you **appear in front of their audience** — which contains precisely the people who hire ([Botdog, 2025](https://www.botdog.co/blog-posts/linkedin-algorithm-2025)). Your comment is distributed to the host's audience, not yours. A comment is seen **~179 times on average** (n=657,722): that many chances to get spotted.

The difference from a student is clear: they sow for two years out; **you target the decision-makers of open roles, now**. Your approach is more surgical and faster. The full "visibility → conversation → opportunity" path is detailed in [from comment to client](/en/blog/commentaire-au-client-linkedin) — the same mechanics apply to your job search.

## 2. Your candidate ICP: who to comment under to get noticed?

This is lever #1. In an active search, you target three host types:

- **Recruiters and talent acquisition** in your sector who publish — many post roles, tips, behind-the-scenes. Commenting under their posts puts you right in front of them.
- **Hiring managers / leaders** at your target companies (a role's future manager). Commenting under *their* posts gets you known by the final decision-maker, not just the recruiter.
- **Reference creators in your field**: their audience is full of peers, recruiters and managers in your niche — broad visibility at once.

At equal effort, **who** you comment under swings your visibility by a factor of 1 to 40+: across 4,861 creators, the median earns **36 impressions/comment**, a top 10% **124 (~3.4x)**, a top 1% **357 (~10x)** (see [who to comment on](/en/blog/sur-qui-commenter-linkedin)). To aim right without wasting time — an asset when every week counts — LinkHub's **[AI profile recommendation](/en/features/ia-recommandation-profils)** infers your target and suggests, across **100,000+ profiles**, the best hosts. The conceptual logic is in [the ICP of a comment](/en/blog/icp-commentaire-linkedin).

## 3. Comment early and well to get noticed (not just seen)

Getting noticed isn't just showing up: it's **landing**. Two reflexes.

**Early.** Commenting in the **first 30 minutes** earns **~3.8x more** than after 24h (391 vs 104 impressions; n=261,137; see [when to comment](/en/blog/quand-commenter-sur-linkedin)). In an active search, it pays twice: you're visible **and** among the first comments, exactly where the recruiter looks. Group your target hosts into **[personalized feeds](/en/features/feeds-personnalises)** to miss no post.

**Well.** Aim for **15-40 words** (a 10+ word comment weighs more than a like). For a candidate, the goal is to **demonstrate competence without claiming it**: a precise piece of experience, an analysis, a sharp question that shows you know the topic. It's your portfolio in action — far more convincing than a CV. Draw on the [comment examples](/en/blog/exemples-commentaires-linkedin) and [how to write a good comment](/en/blog/ecrire-bon-commentaire-linkedin).

## 4. A concrete job-search comment example

Say you're after a project manager role, and the operations director of a company you target publishes a post about recurring delivery delays.

Bad comment: "Great analysis! I'm a project manager actively looking, my profile might interest you." — it screams "hire me," it puts people off.

Good comment:

> "The point that delays come less from execution than from fuzzy upfront scoping — I lived that on my last projects. What unblocked it for us: a 90-min workshop with stakeholders to lock scope BEFORE kickoff — we cut delays by a third over two quarters. How do you secure that scoping when the client pushes to start fast?"

Why it works: it **demonstrates competence** through a concrete result, it speaks the role's language, it opens a conversation. The director — a potential decision-maker — sees a candidate **who knows what they're talking about**, without having to say it. She clicks your profile. If a role opens, you're no longer an anonymous CV: you're "the person who made that sharp comment."

With LinkHub, spotting the right post the moment it drops and writing a **[personalized AI comment](/en/features/ia-commentaires-personnalises)** (always reviewed by you) takes **~29s measured** (median, n=44,523) — a targeted routine fits in a few minutes, without eating into your applications and interviews.

## 5. From comment to interview: moving to DMs

Visibility isn't enough: you need to **convert**. In an active search, the tempo is tight.

- **Commenting** regularly on target recruiters and managers makes you familiar — you're no longer a stranger when you apply.
- **Replying in the thread** builds a public, professional connection.
- **Moving to DMs** at the right moment, without begging: "I enjoyed our exchange under your post on [X]. I'm looking for a [Y] role and your approach resonates — would you be open to 15 min to discuss?" A warmed message beats a cold InMail.
- **Applying warm**: if you apply where you've already commented, your CV is opened **by someone who already knows you**. That's the whole point.

That's how you turn borrowed visibility into opportunities — the path is detailed in [from comment to client](/en/blog/commentaire-au-client-linkedin). Keep your target hosts in [personalized feeds](/en/features/feeds-personnalises) to stay present throughout your search.

## FAQ

**Does commenting really help find a job?**
Yes, indirectly but powerfully. A large share of roles is filled through networking, not cold applications ([LinkedIn, 2025](https://business.linkedin.com/content/dam/me/business/en-us/talent-solutions/resources/pdfs/future-of-recruiting-2025-stff.pdf)). Commenting gets you spotted by recruiters and managers before you even apply — so your application arrives warmed.

**How is this different from a student networking?**
Tempo and target. A student sows for two years out; you target the recruiters and hiring managers of open roles now. Be more surgical: fewer, better-chosen hosts, and faster to move to a message.

**Who should I comment under when job hunting?**
Recruiters/talent acquisition in your sector, hiring managers at target companies, and reference creators in your field. A top 10% of the target earns ~3.4x the median. See [who to comment on](/en/blog/sur-qui-commenter-linkedin) and the [AI profile recommendation](/en/features/ia-recommandation-profils).

**Should I say I'm looking for a role in the comment?**
No. A comment that begs for a job puts people off. Demonstrate competence (experience, analysis, a sharp question); the DM, later, will carry the ask.

**How much time should I spend when actively searching?**
A few minutes a day is enough: 5-10 targeted comments (~29s each with LinkHub). It complements your applications and interviews, it's not a substitute. The structure is detailed in [comment routine](/en/blog/routine-commentaires-linkedin).
