Turning comments into pipeline
Cubeduck · LinkedIn marketing for founders
The short answer
Social selling on LinkedIn is not a separate skill from posting. It is what happens in the comments under someone else's post, where a founder can reach an audience that took someone else years to build, at no cost beyond a few minutes and a genuine reaction.
Done well, a comment starts a real exchange with someone in the target audience. Done as a reflex, it reads as noise and gets scrolled past with everyone else's.
The return on commenting well often shows up faster than the return on posting, because the audience is already there and already paying attention.
What social selling on LinkedIn means for a founder
Social selling on LinkedIn, stripped of the phrase, means showing up in front of people who do not follow the founder yet, inside content they already chose to read. A comment on a well-placed post reaches everyone else reading that post, and everyone who later opens the notification that someone replied to it.
This is the cheapest reach available to a founder with no following of their own yet. It does not require an audience, a content calendar or a strategy document. It requires picking the right ten minutes of the day and the right handful of posts.
Social selling is the tidy name for it. In practice it is far less systematic than the name suggests: it is being useful in public, near people who might buy.
Which posts are worth commenting on
Not every post in the feed is worth ten seconds, let alone a thoughtful reply. The posts worth commenting on tend to share three things: someone in the target audience wrote them, that person is already replying to comments, and the topic sits close enough to what the founder sells that a comment can add something real rather than just agreement.
A founder selling to marketing leaders gets more from commenting on a marketing leader's post about a hiring mistake than from commenting on a well-known CEO's post that already has four hundred replies. The first is a room with ten people in it who might actually read a new comment. The second is a stadium.
This matters even more during the quiet weeks after a founder starts posting, when comments reach an audience faster than a new profile's own posts can.
The comment that starts a conversation, and the one that kills it
The difference is usually one sentence. A comment that repeats the post's point back in different words, or opens with "Great post!", gives the original author nothing to reply to. A comment that adds a specific detail, states a disagreement politely, or shares a short story from the founder's own experience gives them something to respond to.
| Situation | Comment that goes nowhere | Comment that starts a conversation |
|---|---|---|
| Post about a hiring mistake | "So true, hiring is hard!" | "Had the opposite problem last year, hired too fast for a senior role and it cost us the quarter. What made you catch it as early as you did?" |
| Post sharing a strong metric | "Impressive number!" | "Curious what changed to get there. We hit the same plateau at that stage and it took three months to find the actual cause." |
| Post with a strong opinion | "Couldn't agree more." | "Mostly agree, though I would push back on the timeline part. We tried moving faster on this and it broke trust with the team instead." |
The right-hand comment works because it adds something the author did not already know: a detail, a number or a specific disagreement.
Where useful tips into spammy
The line sits at whether the comment could have been written without reading the post. A comment that only praises, or one that pivots straight to what the founder sells, reads as spam even when it is polite. "Interesting take, we solve exactly this at [company]" is a pitch wearing a comment's clothes, and most people can tell within a sentence.
A useful test: would this comment make sense pasted under a different post on the same topic? If yes, it was never really about that post, and it will read that way to everyone who sees it.
Comment patterns that build pipeline
- Adding a specific number, result or detail the post did not mention
- Disagreeing with one part of the post while agreeing with the rest, and saying why
- Asking a question that only someone who read the whole post could ask
- Sharing a short, relevant experience that mirrors or contrasts with the post
- Tagging a specific person only when they would genuinely find the post useful
Comment patterns that kill the thread
- Restating the post's headline in different words
- Opening with "Great post" or "So true" and nothing else
- Pitching a product or service in the same breath as the compliment
- Posting the same comment, or a close variant, under several unrelated posts
- Writing a comment longer than the post itself
What happens after someone replies
A reply is the actual result of the ten minutes spent commenting, and most of it gets wasted by rushing it. The reply deserves a real answer, not a one-line acknowledgement, because the exchange is now happening in front of the same audience that saw the first comment.
The better move is to keep the exchange where it started for one or two more replies, then move it forward only if the other person shows genuine interest, for example by asking a question that suggests they have the problem the founder solves. At that point, a direct message that references the actual exchange ("following up on what you said about X") lands as a continuation of a conversation, not a cold pitch.
The moment a comment turns into a pitch, everyone reading it, including the person who might have replied, recognises the pattern and moves on. It also uses up the one interaction most strangers will tolerate before deciding someone is only there to sell.
A comment thread that stays useful for three or four exchanges is worth more than a pitch on the first one. It is one of the few parts of a founder's LinkedIn presence that costs nothing but time, which is also why the paid work Cubeduck does starts with strategy, not with comments: knowing which posts and which audience to comment on in the first place is what makes the ten minutes worth spending. On the Growth plan that engagement work is part of the retainer, as how Cubeduck works explains.
Common questions
What is social selling on LinkedIn?
It is building relationships and visibility through genuine interaction on the platform, most often by commenting thoughtfully on posts from people in the target audience, rather than only posting original content.
Is commenting on LinkedIn actually effective for lead generation?
It can be, because it reaches an audience someone else already built. The comment still has to add something real; a generic compliment reaches the same audience but rarely leads anywhere.
How many comments should I leave on LinkedIn each day?
A small number of thoughtful comments on the right posts outperforms a large number of generic ones. Ten focused minutes a day is usually enough to find two or three posts worth a real reply.
Should I comment as myself or as my company page?
As the founder. A company page comment reads as marketing; a founder's comment reads as one professional talking to another, which is the entire point of social selling on LinkedIn.
