What is the LinkedIn Social Selling Index?

The Social Selling Index — SSI if you're keeping it short — is LinkedIn’s way of measuring how well you're building your brand, engaging with insights, and building strong relationships — all key elements of social selling success.

Essentially, it's a reflection of your social selling activities on the platform. Your SSI score ranges from 0 to 100 and is based on 4 pillars:

⭐️ Establishing your professional brand: Completing your LinkedIn profile with the customer in mind and becoming a thought leader by publishing meaningful content.

🔍 Finding the right people: Using LinkedIn's search and research tools to identify prospects.

📣 Engaging with insights: Discovering and sharing valuable information to initiate or maintain a conversation.

🤝 Building relationships: Strengthening your network by connecting and establishing trust with decision-makers.

Pro Tip: LinkedIn updates your SSI score daily — so even small, consistent actions can lead to long-term growth.
