LinkedIn 1st, 2nd, and 3rd Degree Connections: What They Mean and Why They Matter
If you've spent any time on LinkedIn, you've seen those little numbers next to people's names. A "1st" next to a colleague, a "2nd" next to someone you almost know, a "3rd" next to a stranger. Most people understand the basics, but few think strategically about what these degrees mean for outreach, visibility, and network growth.
Here's what each degree actually means, and how to use them.
What Are Degrees of Connection?
LinkedIn's degree system maps how closely you're connected to another person through your network. It's borrowed from the concept of "six degrees of separation," though LinkedIn only shows three.
Think of it as a chain. You're at the center. Everyone you're directly connected to is one link away. Everyone connected to them is two links away. And so on.
1st Degree Connections
Definition: People you're directly connected to on LinkedIn. You've either sent them a connection request they accepted, or they sent you one and you accepted.
1st degree connections can:
- Message you directly (and you can message them) without any InMail credits
- See your full profile, including contact information if you've shared it
- See your posts and updates in their feed
- Endorse your skills and write recommendations
Your 1st degree network is your most valuable LinkedIn asset. These are the people who already know you exist and have opted into a relationship with you. Engagement from them amplifies your content to their networks, and they're the most likely to respond when you reach out.
How to use them: Don't just collect 1st degree connections and ignore them. Engage with their content, send occasional messages, and look for ways to add value. A warm 1st degree network is worth far more than a large cold one.
2nd Degree Connections
Definition: People who are connected to at least one of your 1st degree connections, but not directly connected to you. You share a mutual connection.
2nd degree connections are the most interesting category for outreach. They're close enough that you have social proof (a shared connection), but far enough that you haven't met. LinkedIn shows you the mutual connection, which gives you a natural conversation opener.
When you visit a 2nd degree profile, you'll see a "Connect" button. You can send a connection request with or without a note. You can also ask your mutual connection for an introduction.
How to use them: 2nd degree connections are your warmest cold outreach targets. Before sending a connection request, check who your mutual connection is. If it's someone you know well, consider asking them to introduce you. If the mutual connection is more distant, you can still reference it in your note: "I noticed we're both connected to [Name]" adds instant credibility.
When running outreach campaigns, filtering for 2nd degree connections consistently produces higher acceptance rates than targeting 3rd degree or beyond. The shared connection creates implicit trust.
3rd Degree Connections
Definition: People connected to your 2nd degree connections. You're three links away from them in the network.
3rd degree connections are essentially strangers on LinkedIn. You have no direct social proof, no mutual connection visible to you, and they have no reason to recognize your name. LinkedIn shows their first name and last initial only (e.g., "Sarah M.") unless you're connected.
You can still send connection requests to 3rd degree connections, but your acceptance rate will be lower. Without a mutual connection or a compelling reason to connect, many people will ignore or decline.
How to use them: 3rd degree outreach requires more work on the message itself. You can't rely on social proof, so your connection request note needs to be specific, relevant, and immediately clear about why you're reaching out. Generic notes like "I'd like to add you to my professional network" will get ignored.
The best approach: find a genuine reason to connect. Did they post something you found valuable? Do you work in the same niche? Are you targeting the same customer segment? Lead with that.
Beyond 3rd Degree: Out of Network
People outside your 3rd degree network appear as "LinkedIn Member" with no name visible. You can't send them connection requests directly. To reach them, you'd need to use LinkedIn InMail (which requires Premium or Sales Navigator) or find a path through your network to get closer.
How Degrees Affect What You Can See
Your degree of connection affects profile visibility:
| Feature | 1st Degree | 2nd Degree | 3rd Degree |
|---|---|---|---|
| Full name | Yes | Yes | First name + last initial |
| Full profile | Yes | Partial | Limited |
| Direct message | Yes | No (need InMail) | No (need InMail) |
| Contact info | If shared | No | No |
| Mutual connections | N/A | Yes | Sometimes |
This is why growing your 1st degree network strategically matters. Every new 1st degree connection expands your 2nd degree network dramatically, bringing more people into your warm outreach range.
Outreach Strategy by Degree
For 1st Degree Connections
You already have access. The question is how to use it without being annoying.
- Reach out with context: reference something specific about them or their work
- Don't pitch immediately. Start with a genuine question or observation
- Use voice messages for a more personal touch (LinkedIn supports them)
- Re-engage dormant connections by commenting on their posts before messaging
For 2nd Degree Connections
This is your sweet spot for outreach campaigns.
- Always mention the mutual connection if it's someone relevant
- Personalize your connection request note with something specific to them
- After connecting, wait a day or two before sending a follow-up message
- Keep the first message short and focused on them, not your pitch
For 3rd Degree Connections
Requires more effort and a stronger hook.
- Lead with value: share a resource, insight, or observation relevant to their work
- Be specific about why you're reaching out to them in particular
- Keep the note under 200 characters. Shorter is better when you have no social proof
- Consider whether Sales Navigator would help you find better 2nd degree targets instead
Growing Your Network Strategically
The goal isn't to connect with everyone. It's to build a 1st degree network that puts the right people in your 2nd degree range.
A few principles:
Connect with connectors. People who are well-connected in your target industry expand your 2nd degree network faster than anyone else. One connection with a well-networked recruiter or investor can put hundreds of relevant people within reach.
Engage before you connect. Comment on someone's post before sending a connection request. When your request arrives, they'll recognize your name. Acceptance rates go up significantly.
Quality over quantity. LinkedIn has limits on connection requests (around 100 per week for most accounts). Use them on people who are genuinely relevant to your goals.
Use LinkedIn's "People You May Know." This feature surfaces 2nd degree connections based on shared connections, industry, and location. It's a good source of warm outreach targets.
The Bottom Line
Understanding degrees of connection isn't just trivia. It shapes your entire outreach strategy. 1st degree connections are your active network. 2nd degree connections are your warmest prospects. 3rd degree connections require more effort and a stronger message.
The most effective LinkedIn outreach starts by mapping your network, identifying the 2nd degree connections worth targeting, and crafting messages that acknowledge the shared context. Tools like Outly can automate this process, helping you run personalized connection campaigns at scale while keeping your outreach relevant and human.
