Spend 15 minutes commenting on other people’s LinkedIn posts before publishing your own, and you might get more impressions. That is the advice circulating among creators who want to grow faster on LinkedIn. The idea sounds logical: become active, engage with other people, and give the algorithm a reason to show your content to more users.
But there is one problem. There is no established rule that commenting before posting automatically increases your LinkedIn reach. You could spend 15 minutes leaving thoughtful comments, publish an excellent post, and still see fewer impressions than you expected. Meanwhile, someone who publishes without commenting beforehand might reach thousands of people.
So, is this popular LinkedIn growth hack worth your time? In my experience, commenting can be a powerful part of building a personal brand, but not necessarily for the reason most people think. Instead of treating it as a secret algorithm trick, I would focus on how commenting helps people discover your expertise, recognize your name, and develop a reason to follow your work.
Does LinkedIn Reward You for Commenting Before Posting?
One of the most persistent LinkedIn growth theories is that engaging with other people’s content immediately before publishing your own signals to the algorithm that you are active. According to this theory, spending a set amount of time commenting can help your next post receive more distribution. It is an appealing idea because it turns an unpredictable process into a simple routine, but LinkedIn has not publicly established that commenting for a specific number of minutes guarantees additional reach.
LinkedIn uses multiple signals to rank and distribute content, and the exact weighting of those signals is not fully public. Your audience, the relevance of your post, and how people respond to it can all influence performance. Commenting contributes to your activity on the platform, but that does not prove that it directly increases the distribution of your next post.
This distinction matters because creators often confuse correlation with causation. If someone comments on ten posts before publishing and then receives more impressions than usual, the comments might not be responsible for the increase. Perhaps the topic was more relevant, the opening was stronger, or the audience happened to be more active that day.
I would not build an entire LinkedIn strategy around an algorithm theory that cannot be reliably verified. Instead, I would use commenting for the benefits it can create regardless of whether it influences distribution, particularly professional visibility, meaningful conversations, and stronger relationships with the people you want to reach.
1. Commenting Can Help People Discover You Before They See Your Posts
Imagine you are a founder who wants to attract potential clients through LinkedIn. You publish three times a week, but most of your posts reach the same audience, and your follower growth has started to slow. Instead of publishing more frequently, you begin contributing thoughtful comments to conversations involving the people you want to connect with.
When your comments add something useful, other readers have a reason to notice your name and potentially visit your profile. They might discover your experience, explore your content, or decide to follow you because your perspective resonates with them. This creates another opportunity for your expertise to be discovered beyond the people who already see your posts.
That is where commenting can support your LinkedIn reach in a broader sense. Even if the algorithm does not give your next post an automatic boost, your contributions can introduce you to people who might not otherwise have encountered your work. Over time, those interactions can help you build recognition within your industry.
For founders, this is particularly valuable because personal branding is not just about publishing content. It is also about becoming a familiar and trusted voice in the conversations that matter to your business. A thoughtful comment can be a small but effective way to demonstrate how you think before someone ever reads one of your posts.
2. Three Thoughtful Comments Can Be More Valuable Than Twenty Generic Ones
I would rather see someone leave three genuinely insightful comments than spend half an hour responding to every post they encounter with “Great insights!” or “Absolutely agree.” Generic comments may create activity, but they rarely give people a meaningful reason to remember the person who wrote them.
Consider a founder who publishes about hiring challenges. You could simply agree that hiring is difficult, or you could contribute a specific observation about why talented candidates sometimes leave the recruitment process, based on your own professional experience. The second comment adds value to the conversation and gives other readers a glimpse of your expertise.
This is an important distinction when building a personal brand. Your comments communicate something about your judgment, communication style, and professional perspective, just as your original posts do. If you consistently contribute useful ideas to relevant discussions, people can begin associating your name with the topics you care about.
I would also be selective about where you spend your time. A comment on a relevant discussion involving your ideal clients may be more useful than a comment on a viral post that has little connection to your professional goals. The objective is not to appear everywhere. It is to become recognizable in the places where your perspective matters.
3. Commenting Can Give You Better Ideas for Your Next Post
One of the most underrated benefits of engaging before publishing is that it helps you understand what your audience is already discussing. Instead of sitting down to create content and wondering what people might find interesting, you can observe real conversations and identify questions, challenges, and opinions worth exploring.
For example, you might notice that several founders are talking about how difficult it has become to differentiate their businesses. Others may be asking how to attract clients without relying entirely on referrals. These conversations can reveal opportunities for content that addresses problems your audience is already thinking about.
You can then use those observations to develop a post that adds something new to the discussion. Rather than repeating what everyone else is saying, you can share your own experience, explain an alternative approach, or challenge an assumption with a well reasoned argument. This gives your content a stronger foundation because it responds to an actual conversation instead of an imagined audience need.
I often encourage founders to think of LinkedIn as both a publishing platform and a place to listen. Your own posts allow you to demonstrate your expertise, while other people’s posts help you understand the questions and ideas shaping your industry. Using both sides of the platform can make your content more relevant and your personal brand more distinctive.
4. Commenting Cannot Rescue a Weak LinkedIn Hook
Let’s say you spend 15 minutes engaging with other people’s posts before publishing your own. You have followed the advice, completed the routine, and finally shared your content. But your opening is vague, your main point is difficult to understand, and readers have no obvious reason to keep going.
The engagement routine cannot compensate for those problems. Even if commenting helps people become more familiar with your name, your post still needs to offer something worth reading. A clear opening, a relevant topic, and a useful perspective remain important parts of creating content that resonates with your audience.
For example, compare “Today I want to talk about personal branding” with “Your personal brand might be attracting attention, but is it attracting the right people?” The second opening introduces a specific tension and gives the reader a reason to consider the question. It does not guarantee more reach, but it makes the purpose of the post easier to understand.
This is why I would prioritize the quality of your ideas before worrying about the exact order of your LinkedIn activities. If you have limited time, spend it developing a stronger argument, choosing a more relevant topic, or making your opening more specific. Commenting can complement good content, but it cannot replace it.
5. The Best LinkedIn Routine Is One You Can Sustain
There is a reason so many LinkedIn growth hacks become popular. They promise a clear formula for improving results, often with a specific number of minutes, comments, or posts. Following a routine can feel productive because it gives you something concrete to do, but productivity is not the same as progress.
If commenting before posting helps you focus, discover useful ideas, and engage with your professional community, keep doing it. You might spend a few minutes reading relevant discussions, contribute one or two thoughtful comments, publish your post, and return later to respond to people who engage with your content. There is nothing wrong with that routine as long as it supports your goals.
However, if you find yourself commenting mechanically because you believe you must complete a 15 minute engagement ritual before every post, reconsider the approach. You do not need to turn LinkedIn into a checklist of algorithmic tasks. Your time may be better spent on a combination of writing, networking, responding to meaningful conversations, and refining your personal brand.
The strongest strategy is one that helps you show up consistently without compromising the quality of your work. You want to build a recognizable reputation, not simply maximize the number of interactions you generate in a day.
How to Test Whether Commenting Before Posting Works for You
If you want to know whether commenting before publishing makes a difference for your LinkedIn account, you can run a simple experiment. Rather than assuming the tactic works or dismissing it entirely, compare your own results across several weeks while keeping your approach as consistent as possible.
Start by reviewing your recent posts and recording their topics, formats, publishing times, impressions, and engagement. Then, for a group of upcoming posts, spend a few minutes commenting thoughtfully on relevant content before publishing. For another group, follow your usual routine without deliberately commenting beforehand. Try to compare posts with similar formats and topics, and recognize that you will not be able to control every variable.
After collecting enough results, look for patterns rather than focusing on one unusually successful or unsuccessful post. Did the posts preceded by commenting consistently perform better, or were the results mixed? Did the comments lead to profile visits, new followers, or conversations with people in your target audience? Those outcomes can help you decide whether the routine deserves a place in your strategy.
Keep in mind that this experiment cannot reveal LinkedIn’s internal algorithm or prove causation with certainty. It can, however, help you determine whether the practice is useful for your account and whether the time you invest in it produces meaningful results.
So, Should You Comment Before Posting on LinkedIn?
My answer is yes, if you are doing it for the right reasons. Commenting before posting can be a useful way to participate in relevant conversations, make your name more familiar, and discover ideas that inform your content. What I would not do is rely on it as a guaranteed method for increasing impressions.
For founders building a personal brand, the bigger opportunity is to combine thoughtful engagement with content that demonstrates your expertise. Publish ideas that reflect your experience, participate in discussions where you can contribute something useful, and focus on becoming recognizable to the people you want to reach. These activities reinforce one another without requiring you to believe in every algorithm hack that circulates online.
Remember that visibility is only one part of a successful LinkedIn strategy. You also want to build trust, communicate a distinctive point of view, and create relationships that can develop into meaningful professional opportunities. A few thoughtful comments can help you do that, but the real value comes from the reputation you build through consistent, relevant contributions over time.
Build a LinkedIn Strategy That Goes Beyond Growth Hacks
I believe the most effective LinkedIn strategies are built around reputation rather than shortcuts. Instead of constantly searching for small algorithmic advantages, focus on making your expertise easier to discover, your perspective easier to remember, and your content more useful to the people you want to attract.
