What is the Social Selling Index?

LinkedIn's SSI is a score from 0–100 that measures how effectively you use LinkedIn to build pipeline. It predicts opportunity volume and quota attainment. Here's what it means, how it's calculated, and how to move it — explained by the person who helped create it.

Definition

The SSI in plain English.

The Social Selling Index (SSI) is LinkedIn's metric for measuring how effectively a professional uses LinkedIn to find, connect with, and build relationships with their target buyers. It's scored 0–100 and updated daily.

LinkedIn created the SSI to give sales teams an objective way to measure social selling adoption — and to show a correlation between LinkedIn activity and real sales outcomes. The index is calculated across four equally-weighted pillars, each worth up to 25 points.

Before SSI existed, there was no standard way to measure whether a rep's LinkedIn activity was actually contributing to pipeline. The SSI solved that. It gave managers a number, gave reps a goal, and gave LinkedIn a way to demonstrate that Sales Navigator wasn't just a directory — it was a system.

"I was in the room when the SSI was being designed. The goal was simple: give sales leaders a metric that proved LinkedIn activity translated to revenue. It wasn't about vanity — it was about pipeline predictability."

Today, SSI is used by enterprise sales organizations worldwide as a baseline metric for social selling programs. A high SSI doesn't just look good — the data shows it directly correlates with more deals, bigger pipelines, and higher attainment.

The Four Pillars

How SSI is calculated.

Each pillar is worth 25 points. Your total SSI is the sum of all four. LinkedIn updates your score daily based on your activity.

Score Tiers

What your SSI score actually means.

The industry average SSI is around 40–45. Where you land matters — and the gap between tiers is measurable in pipeline.

Score
Tier
What it means for your pipeline
0–30
Invisible
LinkedIn is not working for you. Buyers who research you find a thin profile and no consistent presence. No inbound. Low discoverability.
31–50
Below Average
Below the industry average. You're active occasionally but not systematically. Some profile views but no inbound pipeline to show for it.
51–70
Average
Industry average range. You're doing the basics. Some visibility, some engagement. Room to significantly improve pipeline contribution.
71–85
High Performer
45% more opportunities than average. Regular inbound DMs, strong profile view quality, and buyers who know who you are before the first call.
86–100
Elite
Top 1% in your industry. LinkedIn is a consistent pipeline engine. Buyers come to you. Partners reach out. Press finds you. The compounding effect is real.

How to move your score in 30 days.

SSI responds to consistent activity across all four pillars. These are the highest-leverage moves, ordered by impact.

1

Rewrite your profile headline and About section

Pillar 1 (Professional Brand) responds immediately to profile completeness and quality. A buyer-focused headline and a strong About section are the highest-ROI changes you can make in a single session. Don't describe your job title — describe the outcome you create.

→ Impact: Pillar 1, high
2

Post 3x per week for 30 days

Pillar 3 (Engaging with Insights) is the most responsive to consistent content activity. You don't need to go viral — you need to show up. Three posts per week with substantive commentary on your industry will move your score 5–10 points in a month.

→ Impact: Pillar 3, very high
3

Connect with 10 new ICP contacts per week

Pillar 2 (Finding the Right People) tracks connection activity with relevant contacts. Use LinkedIn's search to find VP and C-suite contacts at your target accounts and send personalized connection requests. Quality matters — connect with people who match your ideal customer.

→ Impact: Pillar 2, high
4

Message 5 existing connections per week

Pillar 4 (Building Relationships) responds to genuine outreach to your existing network. Not pitches — check-ins, sharing relevant content, congratulating milestones. The goal is to activate warm relationships, not manufacture cold ones.

→ Impact: Pillar 4, medium-high
FAQ

SSI questions, answered.

How do I check my SSI score?
+
Go to linkedin.com/sales/ssi while logged into LinkedIn. Your score is free to view and updates daily. You'll see your overall score plus a breakdown of each of the four pillars so you can see exactly where you're strong and where you have room to improve.
What is a good SSI score?
+
LinkedIn considers 70+ to be high. The industry average sits around 40–45. If you're above 70, you're outperforming most of your network and your industry. If you're below 50, there are significant gains available — typically within 60–90 days of a structured improvement effort.
Does SSI affect how LinkedIn ranks your content?
+
Yes, indirectly. A higher SSI correlates with a stronger network and more consistent engagement — both of which the LinkedIn algorithm uses to determine distribution. High-SSI accounts also tend to have more followers and better connection quality, which amplifies reach.
Can you game the SSI score?
+
Short answer: not sustainably. The score measures behaviors that also produce real business results — profile quality, connection quality, content engagement, and relationship building. You can juice individual metrics temporarily, but the pillars are designed to measure genuine activity. If you focus on moving the score through real behavior, the pipeline follows.
Do I need Sales Navigator to have a high SSI?
+
No. You can achieve a high SSI score with a free or Premium LinkedIn account. Sales Navigator helps — particularly for Pillar 2 (Finding the Right People) — but it's not required. The core behaviors that drive SSI are available on any LinkedIn plan.
