LinkedIn Social Selling Index

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.

What Is the LinkedIn SSI Score Based On?

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.

Why the SSI Score Matters

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.
