> **The definition, in one sentence.** The **ICP of a comment** isn't the person you sell to — it's the **audience your comment needs to land in front of**. Concretely: **which creators** to comment under so your voice is seen by your ideal prospects. You don't directly choose who reads you; you choose the **host whose audience = your ideal customer**. This guide defines the concept and gives the method to compute it, backed by our first-party LinkHub data.

## Key takeaways

- **ICP = Ideal Customer Profile**: the precise description of the person you want to reach (role, industry, company size, problem). Applied to commenting, it answers a different question: **"who should I comment under to be seen by those people?"**
- **You don't borrow a random audience — you borrow the host's.** Your comment is distributed to the creator's audience, not yours. So the right creator is the one **whose followers match your ICP**. *(see [who to comment on](/en/blog/sur-qui-commenter-linkedin))*
- **The host you pick 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)**. But raw reach isn't enough: you need the **right** reach — the one that contains your ICP.
- **Big account ≠ right ICP.** An off-topic top 1% is worth less than a niche creator whose audience is exactly your prospects.
- **LinkHub computes your ICP for you**: the [AI profile recommendation](/en/features/ia-recommandation-profils) infers your ideal customer, then searches **100,000+ profiles** for the creators with the best ROI for your niche.

## 1. Refresher: what is an ICP?

**ICP** stands for *Ideal Customer Profile*. It's the precise description of the type of person (or company) you want to reach, and for whom your offer is most relevant. A solid ICP usually combines:

- **Role / function**: founder, head of sales, freelancer, HR, marketer…
- **Industry**: B2B SaaS, agency, e-commerce, consulting… *(if you sell B2B, read [commenting in B2B on LinkedIn](/en/blog/commentaire-linkedin-b2b))*
- **Size / context**: solo, small business, scale-up, enterprise.
- **The problem** they're trying to solve — and that you know how to solve.

The ICP is the compass of all your prospecting: it tells you **who** you're addressing. Most people stop there. But on LinkedIn, and especially through comments, there's a missing step.

## 2. The ICP of a comment: not "who I sell to" but "who I comment under"

Here's the nuance this guide exists to clarify, because it's used everywhere without being defined.

When you **post**, your followers read you: your audience = your ICP, ideally. But when you **comment**, you're not distributed to your own audience — **you borrow the audience of the creator you comment on**. Your comment appears in front of *their* followers ([Botdog, 2025](https://www.botdog.co/blog-posts/linkedin-algorithm-2025)).

So the real strategic question is no longer "who is my ideal customer?" but:

> **Which creators should I comment under so my comment lands in front of my ideal customer?**

That's the **ICP of a comment**: translating your ICP into a **list of host creators whose audience matches your prospects**. You don't directly choose who sees you; you choose the host, and the host determines the audience. Picking the right host means putting your comment **right in front of the right people**.

## 3. Why the host's ICP matters more than its size

You might think it's enough to aim for the biggest accounts. Wrong. Two creators can have the same size and radically different audiences — one full of your ICP, the other not at all.

First, the **host you pick already swings visibility by a factor of 1 to over 40**. Across **4,861 creators** who received at least 5 comments from our users:

| Creator commented on | Median impressions / comment | Multiple vs median |
|---|---|---|
| **Median (p50)** | **36** | x1 |
| **Top 10% (p90)** | **124** | **x3.4** |
| **Top 1% (p99)** | **357** | **x9.9** |
| **Maximum observed** | **1,522** | **x42** |

But those impressions only count if they contain your ICP. **Large off-niche reach doesn't convert.** So the right host combines two things:

- **Real reach** (engagement, not just followers) — an account with 8,000 active followers often beats one with 80,000 passive ones;
- **Audience = your ICP** — its followers are your prospects, peers and decision-makers.

This is consistent with reach concentrating on strong creators: per [van der Blom (1.8M posts)](https://www.linkedin.com/posts/richardvanderblom_chapter-1-algorithm-insights-report-2025-activity-7322514599126130688-Q895), "Top Creator" visibility rose from 15% (2022) to 31% (2025). Commenting where reach **and** your ICP concentrate is the best of both worlds. The full "who" numbers are in our [who to comment on](/en/blog/sur-qui-commenter-linkedin) study.

## 4. How to define your comment ICP (method)

1. **Start from your sales ICP.** Who do you want to reach? Role + industry + problem. (E.g., "early-stage B2B SaaS founders who want leads without ads.")
2. **Translate it into audiences.** Where do these people already gather? Under which creators do they comment, like, hang out? Those are your **candidate hosts**.
3. **List 10-20 host creators** whose audience = your ICP, who post regularly and have real engagement *(the full method is in [finding the right posts to comment on](/en/blog/trouver-bons-posts-commenter-linkedin))*.
4. **Comment early and well** under these hosts (the 0-30 min window remains the multiplier — see [when to comment](/en/blog/quand-commenter-sur-linkedin)).
5. **Measure and tighten.** Keep the hosts that bring profile visits and conversations from your ICP; replace the rest.

That host list is your living **comment ICP**. Group them in [personalized feeds](/en/features/feeds-personnalises) to see their posts as soon as they go live and never miss the window.

## 5. How LinkHub computes your ICP automatically

Defining all this by hand is slow and approximate. That's exactly what LinkHub automates with its **[AI profile recommendation](/en/features/ia-recommandation-profils)**:

- it **analyzes your profile and activity** to infer your **ICP** (your ideal customer);
- it searches a base of **100,000+ LinkedIn profiles** for the creators whose audience matches that ICP;
- it ranks those creators by **ROI for your niche and business** — not just the biggest accounts, but the ones whose comments pay off most.

You no longer have to guess who to comment under: the AI hands you the list of highest-ROI hosts, which you then group in [personalized feeds](/en/features/feeds-personnalises). It's the bridge between "here's my ICP" and "here's concretely where to drop my comments today."

## 6. Should you comment on your prospects directly or on the creators they follow?

Both, but not for the same reason.

- **Commenting directly on a prospect** (under their post) is useful to **start a targeted relationship** — they see you, you exist for them. It's the start of the path toward the [message and the relationship](/en/blog/commenter-linkedin-debutant-sans-audience). But a "regular" prospect often has a small audience: raw reach will be low.
- **Commenting on the creators your ICP follows** maximizes **visibility**: you appear in front of dozens or hundreds of prospects at once, via the host's audience. This is the heart of [social selling through comments](/en/blog/social-selling-commentaires-linkedin).

The full strategy combines both: **the big hosts in your niche for visibility**, **your named prospects for the relationship**. That mix is what turns borrowed visibility into [clients](/en/blog/trouver-clients-linkedin-commentaires).

## FAQ

**What is the ICP of a LinkedIn comment?**
It's the audience your comment needs to land in front of, translated into a list of host creators. Since a comment borrows the audience of the creator commented on (not yours), the ICP of a comment = the creators whose followers match your ideal customer.

**What does ICP mean?**
Ideal Customer Profile: the precise description (role, industry, size, problem) of the person you want to reach and for whom your offer is most relevant.

**Should you comment on the biggest accounts?**
Not necessarily. Raw size matters less than how well the audience matches your ICP: a highly engaged niche creator beats an off-topic top 1%. Aim for real reach **and** audience = your prospects.

**How do I find the right creators to comment on for my ICP?**
With LinkHub's [AI profile recommendation](/en/features/ia-recommandation-profils): it computes your ICP and surfaces, from 100,000+ profiles, the highest-ROI hosts for your niche. See also [who to comment on](/en/blog/sur-qui-commenter-linkedin).

**How much does the host choice really matter?**
Hugely. At equal effort, commenting on a top 10% earns ~3.4x more impressions than the median, a top 1% ~10x (LinkHub data, 4,861 creators) — provided that audience contains your ICP.
