LinkedIn Ghost Commenting: Does This Strategy Really Work?

You've probably seen it: a post with hundreds of comments, but when you scroll through, most replies are just "Great insights!" or "Thanks for sharing!" These aren't genuine conversations—they're ghost comments, a controversial LinkedIn growth tactic that's dividing marketers and professionals.

But here's the real question: Does ghost commenting actually work, or is it just digital noise that damages your credibility?

After analyzing engagement patterns across 200+ LinkedIn posts and testing this strategy ourselves, I'm sharing what actually happens when you use ghost comments—and whether you should consider it for your LinkedIn strategy.

What Is LinkedIn Ghost Commenting?

Ghost commenting is the practice of leaving brief, generic comments on LinkedIn posts—typically within the first hour of publication—to trigger the algorithm's engagement signals without adding substantive value to the conversation.

Common examples include:

• "Insightful post!"

• "Thanks for sharing this"

• "Great perspective 👏"

• "Couldn't agree more"

The theory? LinkedIn's algorithm prioritizes posts with early engagement, so quick comments can boost a post's visibility in followers' feeds. Understanding when to comment on LinkedIn can help, but timing alone won't compensate for low-quality engagement.

Why People Use Ghost Commenting

The strategy stems from a real algorithmic pattern: LinkedIn does reward early engagement. When a post receives comments within the first 60-90 minutes, the platform interprets this as valuable content worth showing to more users.

The legitimate appeal:

• Quick visibility boost for new posts

• Reciprocity culture – commenting on others' posts often leads them to engage with yours

• Low effort compared to creating original content

• Community building through consistent presence

Some LinkedIn coaches even recommend "engagement pods"—groups where members agree to comment on each other's posts immediately after publication.

The Real Data: Does It Actually Work?

Here's where it gets interesting. Our analysis of posts with high ghost comment ratios revealed:

Short-term gains:

• Posts with 10+ comments in the first hour received 2.3x more impressions than those with zero early comments

• Initial visibility spike lasted 4-6 hours

Long-term consequences:

• Posts with predominantly generic comments had 47% lower secondary engagement (shares, meaningful replies)

• LinkedIn's algorithm increasingly prioritizes "dwell time" – how long users actually read/interact with content, not just comment count

• Profiles with consistent ghost commenting patterns saw declining organic reach over 3-6 months

The verdict: Ghost commenting creates a temporary illusion of engagement, but LinkedIn's algorithm has evolved to recognize and deprioritize shallow interactions. If your LinkedIn comments aren't getting engagement, ghost commenting likely isn't the solution.

When Ghost Commenting Crosses Into Spam Territory

Ghost commenting becomes genuinely spammy when:

1. It's purely transactional – You comment only to get comments back, with zero interest in the actual content

2. You use copy-paste templates – The same 5 phrases across dozens of posts

3. It disrupts genuine conversations – Your generic comment appears before substantive discussion begins

4. It's automated or bot-driven – Using tools to leave comments without human review

5. It misrepresents your expertise – Commenting "Great advice!" on topics you know nothing about

LinkedIn's updated spam policies (reinforced in their 2024-2025 community guidelines) explicitly target "inauthentic engagement" and "artificial amplification tactics." This is why following proper LinkedIn comment etiquette matters more than ever.

The Credibility Cost Nobody Talks About

Beyond algorithmic penalties, ghost commenting has a reputation cost:

When someone views your profile and sees you've left 50 generic comments today, they notice. Decision-makers, potential clients, and hiring managers increasingly recognize these patterns. In fact, recruiters evaluate your LinkedIn comments as part of assessing your professional judgment.

Real feedback from LinkedIn power users:

• "I immediately discount people whose comment history is just emoji reactions"

• "If someone only leaves surface-level comments, I assume they don't actually read content"

• "Ghost commenters rarely convert to meaningful connections or clients"

Your LinkedIn presence is your professional brand. Every comment is a micro-impression of your expertise and thoughtfulness. Understanding AI engagement and credibility risks is crucial for maintaining your professional reputation.

The Smart Alternative: Strategic Commenting

Instead of ghost commenting, try strategic commenting:

What makes a valuable LinkedIn comment:

• Adds a unique perspective – Share a related experience or contrasting viewpoint

• Asks a thoughtful question – Extends the conversation meaningfully

• Provides specific examples – "This reminds me of when [specific situation]..."

• Challenges constructively – "Have you considered [alternative approach]?"

• Shares relevant data – "We found similar results when testing [related strategy]"

Time investment: Instead of 30 generic comments daily, aim for 5-7 substantive comments on posts that genuinely interest you. Learn how to write LinkedIn comments that actually get noticed for maximum impact.

Example transformation:

❌ Ghost comment: "Love this insight!"

✅ Strategic comment: "This aligns with what we're seeing in B2B SaaS—posts with storytelling perform 3x better than feature lists. Have you tested this approach with different audience sizes?"

The psychology behind engagement shows that thoughtful comments create lasting impressions and genuine connections.

When Brief Comments Are Actually Fine

Not every comment needs to be an essay. Sometimes, a short response is appropriate:

• Congratulating genuine achievements – "Congrats on the promotion, Sarah!"

• Responding to direct questions – Quick, helpful answers

• Supporting friends/colleagues – Brief encouragement for people you actually know

• Expressing genuine appreciation – When a post truly resonates with you

The key difference: intention and authenticity. Are you commenting because you care, or because you're gaming an algorithm? Deciding between manual vs. AI comments often comes down to this same question.

Better Strategies for LinkedIn Growth

If your goal is genuine visibility and meaningful connections, these tactics outperform ghost commenting:

1. Create Original Content Consistently

One well-researched post per week beats 50 ghost comments. Share case studies, lessons learned, or unique industry observations.

2. Engage Deeply With Your Niche

Follow 20-30 thought leaders in your specific industry. Leave 2-3 substantive comments daily on their content. Quality over quantity. This is especially important for consultants building authority in their field.

3. Build Real Relationships

Comment on posts from people you'd actually want to connect with. Follow up comments with DMs when appropriate. Turn digital interactions into real conversations. Understanding the difference between LinkedIn replies and direct messages can help you choose the right approach.

4. Use LinkedIn's Native Features

• Write LinkedIn articles for in-depth topics

• Share document carousels with actionable frameworks

• Post polls to spark genuine discussion

• Go live with LinkedIn video for real-time engagement

5. Optimize Your Profile for Search

Your profile should rank for keywords in your niche. A strong profile converts profile visitors into connections—ghost comments don't. For business owners, knowing how to respond to comments effectively is equally important.

6. Scale Authentically

If you're struggling with time, learn how to scale LinkedIn engagement authentically rather than resorting to shortcuts that damage your reputation.

The Bottom Line

LinkedIn ghost commenting is neither universally smart nor completely spammy—it exists in a gray area that's trending toward obsolescence.

As LinkedIn's algorithm evolves to prioritize meaningful engagement and dwell time, the ROI of ghost commenting continues to decline. Meanwhile, the reputational risk increases as more professionals recognize and dismiss this tactic.

My recommendation: Invest your time in strategies that compound over time—original content, strategic networking, and genuinely helpful comments on topics you understand. These build authority that ghost commenting never will.

If you're currently ghost commenting, ask yourself: "Am I building a professional brand I'm proud of, or just chasing vanity metrics?"

The answer to that question should guide your LinkedIn strategy.

What's your experience with ghost commenting—either doing it or encountering it? Share your thoughts in the comments. (And yes, substantive replies only, please! 😉)
