> **The idea, in one sentence.** When you run an **agency** (marketing, web, recruitment), you sell **expertise** — and nothing proves it better than how you express yourself where your prospects read. The **LinkedIn comment** does three things for you: it generates non-intrusive **B2B leads**, it builds your **authority** as a specialist, and — the agency's unique advantage — it **multiplies your reach when your whole team comments** under the right hosts. This guide lays out the agency-specific tactics. Backed by our first-party LinkHub data; third-party numbers are dated, none invented. ⚠️ The comment feeds the pipeline and authority; it doesn't sign the engagement for you.

## Key takeaways

- **An agency sells expertise — the comment proves it.** A useful comment under a niche post demonstrates your know-how **publicly**, where a sales deck convinces no one.
- **Your unique advantage: the team effect.** Where a freelancer comments alone, an agency can have **5, 10, 20 people** commenting under the right hosts — a multiplied presence your solo competitors don't have.
- **The right host makes all the reach.** Across 4,861 creators, a top 10% earns **~3.4x more** impressions than the median (124 vs 36), a top 1% **~10x** (357). *(LinkHub)*
- **Comment early.** The **0-30 min** window earns **~3.8x** more than after 24h. *(LinkHub, 261,137 comments)*
- **Non-intrusive, unlike cold outreach.** You appear where the prospect already reads — not in an inbox saturated with prospecting agencies.
- **The goal: qualified leads and niche authority.** Each comment aims at a profile visit, then an inbound conversation — a prospect who comes to you because they saw you shine.

## 1. Why the comment is a natural acquisition channel for an agency

An agency has a specific credibility problem: everyone claims to be an expert. In a market saturated with providers cold-prospecting, your deck and cold email drown in the noise. The lock isn't your visibility — it's the **proof** that you're better than the next provider.

The comment solves exactly that. When you comment, thoughtfully, under a niche post, you don't **say** you're an expert: you **show** it, publicly, in front of exactly the prospects who could hire you. It's the most credible form of social selling for an agency — demonstration over declaration *(the full funnel in [finding clients through comments](/en/blog/trouver-clients-linkedin-commentaires))*.

And it's **non-intrusive**: you don't add one more email to the pile of cold outreach your prospect receives every day from other agencies. You appear where they already read, in the conversation that interests them. The terrain helps: reach concentrates on Top Creators — from 15% (2022) to 31% (2025) per [van der Blom](https://www.linkedin.com/posts/richardvanderblom_chapter-1-algorithm-insights-report-2025-activity-7322514599126130688-Q895) — so a few well-chosen hosts put you in front of your whole target market.

## 2. Targeting the hosts where your clients are (the agency's ICP)

An agency doesn't want to be seen by just anyone: it wants to be seen by the **decision-makers who buy its services**. This is where the **[comment ICP](/en/blog/icp-commentaire-linkedin)** becomes central — not "who I sell to," but **which creators to comment under to land in front of those decision-makers**, because a comment borrows the host's audience, not yours.

Concretely, two types of host depending on your agency's field:

- **The thought leaders in your clients' sector** — if you're a marketing agency for SaaS, comment under the creators that CMOs and SaaS founders follow. If you do tech recruitment, comment under the creators that CTOs and Heads of Talent follow.
- **The named prospects** — when a targeted decision-maker posts, comment on them directly to kick off the relationship.

Raw reach isn't enough: you need the **right** reach. A niche creator followed by your 50 target accounts beats a generalist account with 100,000 off-topic followers. LinkHub's **[AI profile recommendation](/en/features/ia-recommandation-profils)** infers your ICP from your profile, then searches **100,000+ LinkedIn profiles** for the best ROI for your niche — and you can build **a shared list** for the whole team (see section 4).

## 3. The comment that builds your authority (example)

For an agency, the comment is a **showcase of know-how**. It should prove your expertise without pitching your services. Aim for **15-40 words**, add an engagement insight, data or a methodological framework; the "Great post 👏" demonstrates nothing *(method in [write a good comment](/en/blog/ecrire-bon-commentaire-linkedin), templates in [comment examples](/en/blog/exemples-commentaires-linkedin))*.

Example, under a founder's post (your prospect) saying "our site converts poorly, we're going to redesign it":

> Before a full redesign, check whether the problem is really the design: across our last 3 engagements, **2 out of 3** had a **load-speed** and above-the-fold message issue, not a layout one. We gained +18% conversion on one just by rewriting the hero. Do you have scroll-depth data before deciding?

This comment does four things: it **demonstrates your web expertise** (data + method), it **didn't pitch** your redesign, it **opens a conversation** the founder will want to continue, and it makes you **familiar** to them and their audience of peers. When the prospect clicks your profile — your landing page — they'll find an agency that's already proven its worth. That's exactly the shift in [from comment to client](/en/blog/commentaire-au-client-linkedin).

## 4. Getting your team to comment: the leverage solos don't have

This is the agency's structural advantage, and the heart of this guide. A freelancer comments alone; you can **orchestrate 5, 10 or 20 teammates** commenting under the same target hosts. Done right, it's a multiplied presence that makes your agency omnipresent in the niche — without anyone spending more than a few minutes a day.

For it to work without turning into spam:

- **A shared host list** — marketing/leadership identifies the target accounts and relevant hosts (the comment ICP); the team executes. Everyone works the same list, grouped in shared [personalized feeds](/en/features/feeds-personnalises).
- **Split the hosts** — to avoid three teammates commenting redundantly on the same post. Each "owns" their hosts.
- **Distinct voices, never copy-paste** — a generic team comment gets spotted instantly and damages your credibility. Everyone comments in their own voice; **[AI-personalized comments](/en/features/ia-commentaires-personnalises)** help you start fast (always validated by a human).
- **A routine, not heroics** — a few targeted comments per person per day is enough. At **~29s per comment measured** (median, n = 44,523), 10 people × 5 comments is a few minutes each.

The cumulative effect: your agency appears, through several faces, under the posts your market reads — week after week. That's niche awareness no solo competitor can match.

## 5. From comment to qualified lead: the journey

The comment is the **first floor** of your acquisition, not the signed engagement. The typical journey for an agency:

1. **The team comments** under the target hosts — the agency becomes omnipresent and credible in the niche.
2. **Profile visit** — an intrigued decision-maker clicks. They're no longer cold: they **chose** to go see who you are. Polished profiles and agency page = a landing page that converts.
3. **Inbound conversation** — often, the prospect comes to you ("I saw your comment under X's post, we're actually looking for…"). It's the opposite of cold outreach.
4. **Qualification and proposal** — the discussion slides toward a discovery call, with a prospect who's already seen you prove your worth.

That's the logic of the [comment acquisition funnel](/en/blog/trouver-clients-linkedin-commentaires), applied to an agency and the team effect. And it compounds: the more your team is present under the right hosts, the more inbound conversations arrive on their own.

## 6. How many leads can an agency really expect?

Be honest with yourself — and with your team. Our data measures **impressions and familiarity with your ICP**: a comment is seen **~179 times on average** (35 median), 3 to 10x more depending on the host, 3.8x more in the 0-30 min window. These are numbers of **visibility and authority**, not a count of leads or signed engagements.

The link between "being seen and credible with your prospects" and "signing engagements" is **reasoning backed by the mechanism**, not a first-party measurement. ⚠️ Correlation isn't causation: the comment creates the ground — authority, familiarity, inbound conversations — but it's your offer, your proposal and your qualification that turn that into a client. Seen this way, the comment isn't a standalone channel: it's the **warming machine** for your agency pipeline, which your sales process then converts.

## FAQ

**Does the LinkedIn comment really generate leads for an agency?**
It generates visibility, authority and inbound conversations with your prospects. It doesn't "open" an engagement on its own — it warms your pipeline by bringing in prospects who've seen you prove your worth, which your sales process then converts. Our data measures visibility, not signed engagements.

**How do I get my team to comment without it turning into spam?**
A shared host list, split hosts (one "owner" per host to avoid redundancy), and distinct voices — never copy-paste. Everyone comments in their own voice under the target accounts, in shared [personalized feeds](/en/features/feeds-personnalises). A generic team comment gets spotted instantly.

**What's an agency's advantage over a freelancer in commenting?**
The leverage: where a solo comments alone, an agency can have 5, 10 or 20 people commenting under the same hosts. This multiplied presence makes the agency omnipresent in the niche, for a few minutes a day per person.

**How do I build my agency's authority through comments?**
By commenting with engagement insights, data and methodological frameworks under your niche's posts — you demonstrate your expertise instead of declaring it. Repetition, by several teammates, under the right hosts, builds niche authority a deck can't give.

**Is the comment less intrusive than agency cold outreach?**
Yes: you don't add one more email to the pile of cold outreach your prospect already gets from other agencies. You appear where they read, in the conversation that interests them — and often, they come to you after seeing you shine.
