What Is LinkedIn SSI? Social Selling Index Explained
LinkedIn SSI, or Social Selling Index, is a score ranging from 0 to 100 that LinkedIn calculates to measure how effectively you use the platform for professional networking, prospecting, and building your personal brand. It was originally developed for sales professionals using LinkedIn Sales Navigator, but all LinkedIn users can access their SSI score for free.
LinkedIn updates your SSI score daily, and it is calculated across four equally weighted pillars, each worth up to 25 points. Understanding your SSI score helps you identify which areas of your LinkedIn presence need attention.
The Four Pillars of LinkedIn SSI
- Establish your professional brand (0-25 points) – Measures how complete and compelling your profile is. A fully optimized profile with a professional photo, keyword-rich headline, detailed experience, skills endorsements, and recommendations scores highest.
- Find the right people (0-25 points) – Tracks how effectively you use linkedin search and prospecting tools to identify and connect with relevant professionals in your target audience or industry.
- Engage with insights (0-25 points) – Measures your content activity: how often you publish posts, articles, or share relevant content, and whether that content generates meaningful engagement.
- Build relationships (0-25 points) – Evaluates the quality and growth of your network. Connecting with decision-makers, engaging in two-way conversations, and growing a relevant network all contribute to this pillar.
How to Check Your LinkedIn SSI Score
You can check your SSI score by navigating to: linkedin.com/sales/ssi. You must be logged in to your LinkedIn account. The page shows your overall score, your score for each of the four pillars, and how you rank compared to others in your industry and network.
What Is a Good LinkedIn SSI Score?
- Below 40 – Indicates an incomplete profile and low platform activity. Significant room for improvement.
- 40-60 – Average range. Most LinkedIn users fall here. Consistent posting and profile work can push you higher.
- 60-75 – Above average. Typical of active professionals who post regularly and have well-optimized profiles.
- 75-100 – Top performer range. Usually active content creators, Sales Navigator users, and LinkedIn influencers.
The LinkedIn industry average SSI is approximately 47. Sales professionals using Sales Navigator average around 60.
Does LinkedIn SSI actually matter?
LinkedIn reports that professionals with higher SSI scores receive 45% more opportunities and are 51% more likely to exceed their quota (for sales roles). Higher SSI correlates with more profile views, better inmail response rates, and greater organic content reach. While SSI is not a direct ranking factor in the LinkedIn algorithm, the behaviors it measures (posting content, building a strong profile, engaging with others) are directly tied to visibility and reach on the platform.
