If you're active on LinkedIn for business development, sales, or networking, you've likely heard of the LinkedIn Social Selling Index, or SSI. This is a score that LinkedIn uses to measure how effectively you are leveraging the platform to build relationships, establish your brand, and engage with your network.
The SSI is a numeric score between 0 and 100, based on four key components of LinkedIn activity. It is designed to give users insight into how well they’re using the platform as a professional networking and sales tool. While originally developed for sales professionals using Sales Navigator, the SSI score is available to all LinkedIn users.
LinkedIn calculates your Social Selling Index score using four pillars:
Building your professional brand
Finding the right people
Engaging with content and insights
Establishing strong relationships
Each category contributes up to 25 points, making a perfect score 100. Your personal breakdown is visualized inside the LinkedIn SSI dashboard, where you can see your strengths and areas for improvement.

LinkedIn doesn't just track your engagement for fun. Your SSI score can have a real impact on how LinkedIn treats your account in terms of visibility, discoverability, and limits.
A higher SSI score tends to correlate with:
Increased reach and visibility in search and feed
Better acceptance and response rates
Higher profile credibility
Fewer restrictions on outbound connection requests
In particular, your SSI score influences how many connection invitations you can safely send per day or week. LinkedIn does not publish an official limit, but based on real-world performance and internal testing, profiles with low SSI scores tend to hit invite limits more quickly.

Improving your SSI score is possible for anyone, regardless of whether you use the free version of LinkedIn or Sales Navigator. The key is consistent, strategic engagement with the platform across all four components.
The table below outlines practical actions that impact each pillar:
Your LinkedIn SSI score is more than just a number. It reflects how well you are using LinkedIn’s tools to connect, communicate, and build credibility. More importantly, it directly influences how much outreach you can safely do on the platform.
If you want to increase your visibility, send more invitations, or become a trusted voice in your network, start by improving your SSI. Small, consistent actions across your profile, content, and outreach can lead to a significantly higher score over time.
