The Moment Everything Clicked
Marcus sent a DM to a prospect he'd been following for weeks. Instead of pitching, he referenced a specific comment she'd made about scaling customer success teams. "That challenge you mentioned about balancing automation with personalization—I've been wrestling with the same thing," he wrote.
She replied within 20 minutes. They had a 45-minute call the next week. Three months later, she became his biggest referral source.
What happened? Marcus didn't just reach out—he built rapport. And on LinkedIn, where every DM feels transactional, genuine rapport is your unfair advantage. Learning how to build rapport on LinkedIn transforms cold outreach into warm conversations.
The Psychology Behind Rapport: Why Some Connections Click Instantly
Rapport isn't about being likeable—it's about creating a sense of familiarity, safety, and mutual understanding. Psychologically, rapport happens when:
- Mirror neurons activate: When someone feels "seen," their brain unconsciously mirrors your behavior and builds trust.
- Similarity bias kicks in: We trust people who seem like us—shared interests, challenges, or values create instant connection.
- Reciprocity is triggered: When you offer value first (insight, empathy, a compliment), people feel compelled to reciprocate.
In person, rapport happens through body language, tone, and energy. Online, you need to rely on words, timing, and context. The good news? Once you understand the psychology, digital rapport becomes predictable and repeatable.
Trust Signals: What Makes You Feel Safe
Before someone engages with you, their brain asks: "Is this person safe? Are they worth my time?" You answer that question with trust signals:
- Personalization: Mentioning specific details from their profile or content
- Shared connections: Mutual contacts or groups signal social proof
- Consistency: Showing up regularly in their feed before reaching out
- Value-first approach: Offering insights, resources, or genuine curiosity without asking for anything
When these signals are present, your outreach doesn't feel like spam—it feels like the start of something real. This is why micro-interactions matter so much: they establish trust before the DM even lands.
Mirroring Tone: The Subtle Art of Matching Energy
One of the fastest ways to build rapport is through tone mirroring—matching the energy, style, and pacing of the person you're engaging with.
Here's how it works:
- Formal tone? Mirror it. Use complete sentences, professional language, and structure.
- Casual tone? Match it. Keep it conversational, use short paragraphs, maybe even throw in a light joke.
- Data-driven? Reference numbers, frameworks, and systems in your replies.
- Story-driven? Share anecdotes, analogies, and examples.
Tone mirroring isn't about being fake—it's about meeting people where they are. When your communication style aligns with theirs, the conversation feels effortless. This technique also applies when you follow up on LinkedIn—matching their energy keeps the momentum going.
Example: Tone Mirroring in Action
Their post: "Just closed our biggest quarter yet. Grateful for the team that made it happen."
Bad comment: "Nice work! Check out my services if you're looking to scale."
Good comment (tone mirrored): "That's huge—congrats to you and the team. Curious what shifted this quarter that drove the results?"
The second comment matches their reflective, team-focused tone. It shows genuine curiosity. It invites conversation. That's how rapport begins.

Shared Interests and Empathy Language
People connect fastest over shared experiences. When you identify common ground—a challenge, a goal, an interest—you create an instant bridge.
How to Find Shared Interests on LinkedIn
- Read their "About" section for clues about what they care about
- Look at the content they engage with—what topics light them up?
- Check mutual connections or groups you're both in
- Notice what they celebrate or complain about in posts
Once you find that common ground, reference it naturally. "I saw you're also navigating the chaos of scaling a remote team—how are you handling async communication?" This type of empathy language shows you're paying attention.
Empathy Language: Phrases That Build Rapport
Empathy isn't just about understanding—it's about expressing that understanding. Use phrases like:
- "That resonates—I've been in a similar spot."
- "I can imagine how frustrating that must be."
- "That makes total sense given what you're building."
- "I'd love to hear how you approached that."
These phrases signal that you're not just reading—you're listening. And listening is the foundation of rapport.
Subtle Rapport Techniques: The Details That Matter
Beyond tone and empathy, there are micro-techniques that strengthen rapport without being obvious:
- Use their name occasionally: "Great point, Sarah—I hadn't thought about it that way."
- Ask open-ended questions: "What led you to that approach?" vs. "Did that work?"
- Validate before adding: "I love that strategy. One thing I'd add is..."
- Share vulnerability: "I tried this and failed—here's what I learned."
- Follow up on previous conversations: "Last time we talked, you mentioned X—how did that turn out?"
These techniques make people feel seen, heard, and valued. That's the essence of rapport. And when you combine this with organized relationship management, you can scale rapport-building without losing authenticity.
Common Digital Rapport Mistakes to Avoid
Building rapport online is delicate. Here are the mistakes that kill it:
- Pitching too soon: Rapport takes time. Don't ask for a sale, intro, or favor in your first message.
- Generic compliments: "Great post!" signals you didn't actually read it. Be specific.
- Talking only about yourself: Rapport is a two-way street. Ask questions. Show curiosity.
- Ignoring their tone: If they're formal, don't be overly casual. If they're casual, don't be stiff.
- Disappearing after one interaction: Rapport requires consistency. Stay visible.
When you avoid these mistakes and focus on genuine connection, you'll notice people responding faster, engaging deeper, and remembering you when opportunities arise.
Frequently Asked Questions
How do you build rapport on LinkedIn without seeming fake?
Be genuinely curious. Ask questions you actually care about. Reference specific details from their content. Rapport isn't about scripts—it's about paying attention and showing up consistently.
How long does it take to build rapport digitally?
It depends on frequency and quality of interactions. With consistent engagement (comments, DMs, likes), rapport can develop in 2–4 weeks. The key is showing up repeatedly without being pushy.
Can you build rapport through comments alone?
Yes! Thoughtful, specific comments build familiarity and trust over time. Many strong LinkedIn relationships start in comment threads before ever moving to DMs.
What if someone doesn't respond to my rapport-building attempts?
Not everyone will engage—and that's okay. Focus on the people who do respond. Rapport is about quality, not quantity. Keep showing up for those who reciprocate.
