Leads from LinkedIn post engagers: likers, commenters and how to message them

People who comment on a relevant LinkedIn post have said something about what they care about, which makes them better leads than a cold list. Rank engagers by effort (a comment beats a like), filter by role and company fit, and write a first message that refers to what they said. Do it by hand or with a tool that respects LinkedIn's limits, and do not scrape, because LinkedIn's terms forbid it.

Post engagement is one of the most useful signals in LinkedIn outreach because it is public, dated and tied to a topic. This post covers what is visible, who is worth contacting, the rule you must not break, and how to write the first message. The statement about LinkedIn's rules comes from its help page, read on 25 October 2026. Where we could not find an official source, we say so.

What does LinkedIn show you about engagers?

On a post you can open, comments appear under the post with the commenter's name, headline and text. The reactions count can usually be opened to list the people who reacted and the type of reaction. Members can limit who sees their activity, so you will not see everyone.

We could not find a current LinkedIn help article that describes the reactions list for personal posts, so this is a description of how the product behaves, backed by third party guides, not an official definition. Those guides also say LinkedIn does not offer a way to filter, sort or export the list, which is why people reach for tools. That leads to the rule below.

What does LinkedIn's rule say about collecting them?

LinkedIn's help page on prohibited software says it does not allow third party software that scrapes the site, changes its appearance or automates activity on it. It cites its User Agreement, which bars bots and unauthorised automated methods and scraping or copying of profiles and other data, and says members who use such tools risk having their accounts restricted or shut down.

That means two safe paths for engager lists: read the list by hand and copy the people you want, or use a tool whose method you have read and accept the risk of. Nobody can promise that an account will never be restricted. Our LinkedIn safety checklist covers limits and pacing.

Which engagers are worth contacting?

Rank by the effort the person put in.

Then filter in this order: role (can they buy or influence?), company fit against your ideal customer profile, engaged in the last 30 days, and not already a customer or in a conversation.

Which posts should you look at?

The post decides the quality of the crowd. Good sources:

1. Posts about the problem you solve, by creators your buyers follow.
2. Competitor and category posts, covered in competitor engagers as intent signals.
3. Your own posts, where engagers already know you.
4. Posts by customers or partners, where their peers comment.

Avoid viral posts with thousands of reactions from unrelated people. A post with 40 relevant comments gives a better list than one with 4,000 random likes.

How do you write the first message?

Refer to what they did, keep it short and make the ask small. Three parts: what you noticed, why you are writing, and an easy next step. The template page LinkedIn message to a post engager has versions for commenters and likers. The pattern, with a made up example:

Hi Dana, I liked your point about onboarding taking longer than the sale. We help teams shorten the handover between sales and onboarding, so I thought it might be worth swapping notes. Would a short chat next week make sense, or is that not a priority right now?

Notes on the example: it quotes the comment, it does not pitch features and it gives a way to say no. It is invented for illustration. Our post on turning a signal into a first line shows more openers.

For likers, do not write "I saw you liked my post". Engage first instead. Our post on pre invite engagement explains how to react or comment on their content before inviting, so the invitation is not the first they see of you.

What about connection requests?

Many engagers are not connected to you. Two routes:

• Invite with a short note that refers to the comment. Keep it to a line.
• Comment back first, then invite. The person sees you before the request arrives.

Sellinger's LinkedIn defaults are 20 invitations a day and 150 a week per account, and every value can be changed. A list of 400 engagers is a few weeks of work at that pace, which is a reason to rank the list before you start. If the person is not connected, an InMail is another route for accounts with Premium or Sales Navigator.

What does a result look like?

On our own account, people who engaged with a relevant post replied at 54.6% and booked 4.54 meetings per 100 messaged, against 21.7% and 0.71 per 100 for a Sales Navigator search. That is one account and one audience, so read it as an example. It shows why we start from engagement. It does not promise your numbers. The full picture, including what faded, is in the case study.

Common mistakes

• Messaging the like. "Thanks for liking my post" tells the person you are working a list.
• Pitching in the first message. Reply to the comment; the pitch can wait for their answer.
• Ignoring the crowd. If most commenters are peers of the author and not buyers, the post is the wrong source, not the message.
• Sending to everyone in a day. Pace follows the account limits, and a burst looks like automation.
• No record. Without a note on which post each person came from, you cannot learn which sources work.

A weekly routine

1. Pick 5 to 10 relevant posts a week.
2. Copy commenters who pass the role and fit filters into a list.
3. Add a one line note about what each person said.
4. Message within about a week of the comment.
5. Record who replied, to which opener, and drop the posts that gave no replies.

Privacy and the law

Contacting people about a work topic raises data protection questions, and the answer depends on the country. Our glossary entry on legitimate interest explains one basis used in the EU and UK, and how did you get my data shows how to answer when someone asks. Honour a stop request straight away.
