5 mistakes business leaders still make on LinkedIn

The issue rarely lies in a lack of willingness. On the contrary, more and more leaders are recognizing the importance of showing up online. But between limited time, lack of method, and uncertainty about best practices, their efforts often become inconsistent, vague, or impersonal. The result? Low-performing content, unclear positioning, and missed communication opportunities.

In this article, we highlight five common mistakes leaders make on LinkedIn: and more importantly, how to avoid or fix them to turn the platform into a real asset for your brand communication.

I. The 5 most common LinkedIn mistakes

1: Posting without a clear objective

This is the number one mistake. Many business owners post simply because they feel they have to be “visible.” But without defining the purpose of their content—whether it's to raise brand awareness, showcase expertise, recruit, or promote company culture—posts often fall flat. Even if the content is interesting, it lacks alignment with a clear communication strategy, which limits its impact.

2: Talking only about yourself instead of your audience’s concerns

It’s natural to want to talk about your company, your wins, or your latest launch. But if your communication is overly self-centered, it quickly loses attention. Your clients don’t just want to know what you’ve accomplished—they want to know how it benefits them. Without a clear connection to their challenges or needs, your message becomes irrelevant. And a message that only speaks to yourself, speaks to no one.

3: Using overly corporate language and lacking a human touch

Some executives post on LinkedIn like they’re writing a press release. The tone is rigid, formal, and flat. But LinkedIn is not a corporate newswire—it’s a space for real people. The most engaging posts are often the most authentic: those that share personal experiences, lessons learned, or honest reflections. These are the moments that build trust and memorability. Cold, impersonal messaging weakens your impact, while a human tone strengthens credibility.

4: Imitating competitors instead of owning your voice

Fear of “doing it wrong” or a lack of inspiration leads some leaders to simply copy what others in their sector are doing—same formats, same phrases, same topics. While imitation might feel safer, it makes you invisible in the long run. What catches attention on LinkedIn is your authenticity: your ideas, your voice, your unique take. Copying means blending into the noise. Creating means standing out.

5: Pushing communication off until “later”

The final mistake? Telling yourself, “I’ll get back to LinkedIn soon”… and then not posting for weeks. The intent is there, but the follow-through is missing. On LinkedIn, consistency is key. Inconsistent posting reduces visibility, weakens your presence, and causes you to miss out on key opportunities. It’s not perfection that drives results—it’s structure, frequency, and staying top of mind.

II. Why these mistakes hurt your visibility and brand image

On LinkedIn, just posting isn’t enough. The algorithm favors content that sparks engagement, fits into a consistent narrative, and feels authentic. If your content is vague, overly promotional, or disconnected from your audience, it will go unnoticed; even if you post regularly. But beyond the algorithm, it’s your audience that matters most. As a leader, your voice carries weight. It reflects your vision, your values, and your positioning. Poor communication sends a mixed signal. It can imply lack of clarity, lack of commitment, or lack of interest in your audience’s needs.

On the flip side, well-structured, personal, and consistent communication can position you as a thoughtful and inspiring leader. It shows that you’re engaged, willing to share your expertise, and open to dialogue. That builds credibility, increases your visibility, and earns long-term trust. LinkedIn isn’t just a bonus channel. It’s a powerful communication platform—but only if you use it with strategy, purpose and authenticity.

III. How to get back on track: simple and effective fixes

The good news? These mistakes are easy to correct. You don’t need to be a communication expert; you just need the right mindset, some helpful tools, and maybe a little guidance. Start by setting clear objectives for each post: are you aiming to inform, engage, recruit, or reassure? Every piece of content should serve a specific intent. That clarity will help you create more purposeful, more impactful messages.

Next, put your audience at the center. Before hitting publish, ask yourself: Why does this matter to my network? What value does it bring them? This simple mental shift transforms a self-centered message into a valuable piece of content. Tone matters too. Ditch the overly formal language. Use everyday words. Tell a quick story. Share a point of view. You don’t have to be polarizing, just real. Authenticity creates connection.

To avoid falling into the copy-paste trap, focus on what only you can say. Your values, your lessons learned, your behind-the-scenes… That’s what makes your content memorable.

Too often, business leaders overlook or neglect it due to a lack of structure or time. But a presence that’s intentional, personal and consistent can elevate your brand image, reinforce your credibility, and create meaningful business opportunities. The goal isn’t to be perfect.
