To warm up leads on LinkedIn, pick a short list of people you want as customers and comment on their posts, usefully and repeatedly, for a few weeks before you ask for anything. The aim is recognition. When your connection request or message finally arrives, it comes from a name they have already seen several times, attached to thinking they found worth reading. One comment will not do that. A dozen spread across a month or two usually does.
This guide covers how to warm up leads on LinkedIn from start to finish: who to pick, how to make sure you see their posts, what to write, how often, and how to tell when someone is ready to hear from you directly.
What “warm” means before you start
A warm lead is someone who would recognize your name in their notifications and have a mildly positive association with it. That is all. They are not necessarily ready to buy, and they have not agreed to anything. The longer definition is in warm leads vs cold leads, but the short one matters here because it tells you what the warm-up is for. You are not trying to persuade anyone in the comments. You are trying to stop being a stranger.
That lowers the bar for each individual comment and raises the bar for consistency. A comment does not need to be brilliant. It needs to be specific, and there need to be more of them next week.
Step 1: Choose a list small enough to keep up with
Twenty to fifty people is a realistic list for one person doing this by hand. Beyond that you start skipping posts, and gaps are what break the effect. Three tests decide who goes on it:
- They could buy, or they strongly influence the person who does. If you have not written down who that is, the free ICP report generator is a quick way to get to a first draft.
- They post. Open their profile, scroll to Activity and look at the Posts tab. Two or more posts in the last month is workable. A single post from two years ago is not. For good-fit leads who stay silent, see what to do when your leads rarely post.
- Their comment sections are not a stadium. A chief executive with 400 comments per post will not register yours. A director at the same company with twelve comments per post will.
Write the list down somewhere you will open daily: a spreadsheet, a notes file, a saved list. Add one column for the date of your last comment and one for a running count.
Step 2: Make sure you actually see their posts
The feed will not reliably show you posts from people you barely know. Fix that on purpose:
- Follow each person. Following does not need their approval, unlike a connection request.
- Once you follow them, click the bell on their profile and choose to be notified about all their posts.
- Check those notifications at a fixed time each day. A comment left while the author is still reading their thread gets far more attention than one left three days later.
The bell has limits, and it becomes noisy past a few dozen people. How to get notified when someone posts on LinkedIn goes through the options in detail. The post monitoring page shows what replaces the bell on a longer list.
Step 3: Tidy what they see when they look back
Every comment you leave carries your name, your photo and the start of your headline. If the comment is good, some authors will click through to your profile. Spend twenty minutes before you start making sure the headline says who you help and with what, in plain words, and that the photo looks like someone they would take a call with. The free LinkedIn profile review will point out the obvious gaps.
Do this once. It is preparation, and it should not become a reason to delay the commenting.
Step 4: Write comments that give them something
The comments that build recognition are the ones the author remembers reading. Three kinds do that reliably. Rotate between them so you do not sound like a formula.
Take one lead as an example: Dana, a VP of Operations at a regional freight brokerage. Over three weeks she posts three times.
Pick up a detail and ask about it
Dana writes about cutting detention time by letting carriers book their own dock appointments.
The self-booking makes sense, but the line that stood out was the 30-minute grace window instead of a hard slot. Most detention disputes I hear about start with a truck that was eight minutes late. Did the grace window change how often you had to rebook?
Why it works: it quotes something from the middle of the post, so she knows you read it. It shows you know the territory. The question is easy to answer in one line, which makes a reply likely.
Add your own experience
A week later she posts about training new dispatchers through ride-alongs with drivers.
We ran ride-alongs for new dispatchers too, and they only stuck once the drivers chose who rode with them. When ops assigned the pairings it felt like an audit.
Why it works: it adds a data point she did not have and asks for nothing. Other readers of her post benefit too, which makes her look good for having started the thread.
Mark a moment like a person would
Then she shares that her team got through peak season without a missed service-level target.
Two peak seasons in a row without a miss is rare in brokerage. Credit to the night team in particular. They never make the photo.
Why it works: it is short, warm and specific to her world. Not every touch has to carry an insight.
None of the three mentions what you sell. That is deliberate, and how to comment on a prospect’s post without selling explains where the line sits. For more patterns to rotate through, see what to comment on LinkedIn.
Step 5: Pace it like a person
Warming is a frequency game played slowly. A few rules keep it from tipping into pestering:
- One comment per post. Reply if she answers you, but do not leave a second top-level comment.
- No more than one comment a day on any one person. If someone posts three times in a day, pick the post you have most to say about.
- Skip posts where you have nothing to add. A like is enough. A forced comment is worse than none.
- Keep going for at least four weeks. Three comments in three days followed by silence reads as a campaign. Eight comments over five weeks reads as someone who follows her work.
How many touches you need is a judgment call. A workable planning model, with honest caveats about where the numbers come from, is in how many touches does it take.
What four weeks looks like for one lead
- Week 1: follow Dana, turn on the bell, comment on the dock-appointment post. She likes the comment and answers the question in a line. You reply once with a thank-you and one more detail.
- Week 2: comment on the ride-along post. No reply this time. That is normal. Like a post she reshares from her CEO.
- Week 3: comment on the peak-season post. She likes it. You notice she has viewed your profile.
- Week 4: she posts a question about carrier scorecards. You answer it properly, in four sentences. She replies by name.
That is four comments, two replies from her and a profile view. She is not a customer. She is, however, someone who will read a connection request from you instead of ignoring it.
Step 6: Reach out when the signals show up
Outreach comes after recognition, and recognition shows itself. Look for replies to your comments, likes on them, a profile view, or a connection request from their side. When you have seen two or three of those, send your own connection request with a short note that refers to a specific thread. When to send the DM ranks the signals and covers what to do when none appear, and sending the connection request after you’ve commented has wording you can adapt.
Keep commenting after you connect. If the comments stop the day the pitch starts, the lead will draw the obvious conclusion about why you were there. For leads whose timing is months away, lead nurturing on LinkedIn turns this into a tiered list with a cadence for each tier.
Mistakes that undo the work
- Praise with nothing in it. “Great post, thanks for sharing” gives the author nothing to remember you by.
- A pitch in the comments. Mentioning your product under someone else’s post tells them, and everyone reading, what you came for.
- The same-day DM. One comment at 9am followed by a message at 9:15 turns the comment into a setup.
- Commenting on everything within seconds. Speed plus volume looks automated, even when it is not.
- Disappearing. Two good weeks followed by a month of silence leaves you roughly where you started.
Doing this for more than a handful of leads
By hand, the method above holds up for a few dozen leads if you give it twenty to thirty minutes a day. Past that, the bottleneck is noticing posts in time and keeping count. That is the part Icebreakly takes over: you add the profiles you care about, it watches for their new posts, drafts a comment in your voice for each one, and keeps a touch count per lead. You can approve every draft before it posts or let it run on autopilot inside limits you set.
It stops there. Icebreakly does not send connection requests or messages, and it does not find leads for you, so the list and the outreach stay with you. LinkedIn’s terms also restrict third-party automation, so no tool of this kind is free of risk. The automation safety guide sets out what that means in practice.
Start with ten names this week
Pick ten people who fit, who posted in the last fortnight, and whose comment sections are small enough to be seen in. Follow them, turn on the bell, and leave one specific comment on each person’s next post. Keep a count. In four weeks you will know which of them recognize you, and those are the ones to reach out to first.
Frequently asked questions
How long does it take to warm up a lead on LinkedIn?
It depends mostly on how often the lead posts. Someone who posts once or twice a week gives you enough openings to become a recognized name in about four to six weeks. Someone who posts once a month will take several months through comments alone, so you will need to add other touches, such as engaging with their company’s posts or with comments they leave elsewhere.
Do I need to be connected to a lead before I start commenting on their posts?
No. You can comment on any public post without being connected, and you can follow someone without their approval so their posts are easier to find. Many sellers comment first and send the connection request later, once the lead has seen their name a few times, because the request then comes from someone familiar.
Should I like a lead’s post as well as comment on it?
Yes, it costs nothing and it is what a person who found the post worth commenting on would normally do. A like on its own is a weak touch because it gets bundled with everyone else’s reactions, so treat it as a supplement to a comment or as a light touch on days when you have nothing useful to add.
Can I warm up leads who are much more senior than me?
You can, but pick the venue carefully. A chief executive’s post with hundreds of comments is a hard place to be noticed. A post by a vice president or director at the same company, with a dozen comments, is easier, and those people often shape the buying decision anyway. Seniority matters less than whether your comment shows you understand their problem.
