If you have ever looked at a LinkedIn profile and seen a small number — 1st, 2nd, or 3rd — next to someone’s name, you have already encountered LinkedIn’s connection degree system. Understanding exactly what these degrees mean, and more importantly how to use them strategically, is one of the most underrated skills in B2B networking. This guide explains everything you need to know.
What Do 1st, 2nd, and 3rd Degree Connections Mean on LinkedIn?
LinkedIn organises your network into three degrees of connection, each representing a different level of proximity to you. A 1st degree connection is someone you are directly connected with — you have either sent them a connection request that they accepted, or vice versa. You can message 1st degree connections directly at any time without needing a paid account.
A 2nd degree connection is someone who is connected to one or more of your 1st degree connections, but is not yet directly connected to you. Think of them as a friend of a friend. A 3rd degree connection is someone connected to your 2nd degree connections — further removed from your network, but still visible and reachable through LinkedIn’s platform. Beyond 3rd degree, profiles are listed simply as ‘LinkedIn Members’ and have very limited visibility.
Why Do LinkedIn Connection Degrees Matter for B2B Lead Generation?
Connection degrees directly determine what you can see, who you can message, and how warm or cold a potential outreach will be. Your 1st degree connections are your warmest prospects — you already have an established link and can reach them directly. Your 2nd degree connections represent your largest pool of qualified warm leads, because you share mutual connections that can provide social proof and even facilitate introductions.
Understanding this structure is fundamental to building an effective LinkedIn lead generation strategy. The most successful B2B prospectors focus heavily on 2nd degree connections — using mutual contacts as credibility anchors to warm up their outreach before ever sending a message.
How Should I Approach 1st Degree Connections on LinkedIn?
Your 1st degree connections are your most accessible audience on LinkedIn. These are people who have already accepted a relationship with you, which means they are far more likely to engage with your content, respond to your messages, and consider your services when a relevant need arises. Yet most LinkedIn users dramatically underutilise this existing network.
The best strategy for 1st degree connections is to nurture them consistently through valuable content and genuine engagement. Comment on their posts, congratulate them on milestones, and occasionally reach out with a useful resource or insight relevant to their world. This consistent presence means you are top of mind when they — or someone they know — need what you offer. A well-managed LinkedIn content creation strategy keeps you visible to your 1st degree network without requiring manual effort every day.
How Do I Convert 2nd and 3rd Degree Connections into Leads?
Your 2nd degree connections are the goldmine of LinkedIn prospecting. Because you share a mutual connection, there is already a thread of implied trust — you are not a complete stranger. When reaching out to a 2nd degree connection, referencing the mutual connection naturally, or even asking that mutual contact for a warm introduction, dramatically increases your acceptance and response rates compared to cold outreach.
For 3rd degree connections, the approach requires more groundwork. Before reaching out, spend time engaging with their content — leaving thoughtful comments on their posts builds familiarity before any direct message is sent. According to LinkedIn’s B2B marketing resources, prospects who have seen your content before receiving a connection request are significantly more likely to accept and engage than those receiving a completely cold approach.
Using LinkedIn’s Search to Find and Filter by Connection Degree
LinkedIn’s search functionality allows you to filter results by connection degree, making it straightforward to build targeted prospect lists at each level of your network. When using the People search, you can filter by 1st, 2nd, or 3rd degree connections simultaneously with filters for industry, job title, company, location, and more.
A smart prospecting workflow uses these filters to prioritise outreach, starting with 2nd degree connections who match your ideal client profile, warming them through content engagement, and then sending a personalised connection request that references your shared connection. This systematic approach to working through your LinkedIn network degrees is at the core of how we build lead generation systems for clients at Attention Grabbers.
Frequently Asked Questions
What is a 1st degree connection on LinkedIn?
A 1st degree connection on LinkedIn is someone you are directly connected with. You have accepted each other’s connection requests and can message one another directly without needing a paid account or InMail credits.
What is a 2nd degree connection on LinkedIn?
A 2nd degree connection on LinkedIn is someone who is connected to one or more of your 1st degree connections but is not yet directly connected to you. They are visible in your search results and can be reached via a connection request or through a mutual contact introduction.
What is a 3rd degree connection on LinkedIn?
A 3rd degree connection on LinkedIn is someone connected to your 2nd degree connections. They are further from your immediate network but still reachable through LinkedIn’s platform, though with more limited visibility and messaging options than 1st or 2nd degree connections.
Can I message 2nd or 3rd degree connections on LinkedIn without connecting first?
You can message 2nd and 3rd degree connections using LinkedIn InMail, which is available on paid accounts. Alternatively, you can send a personalised connection request and begin the conversation once they accept.
How many LinkedIn connections should I aim for to maximise lead generation?
Quality matters far more than quantity. A network of 1,000 to 3,000 highly relevant 1st degree connections in your target industry and seniority level will deliver significantly better lead generation results than a large, unfocused network of tens of thousands.
