LinkedIn SSI (Social Selling Index)
LinkedIn's proprietary score measuring how effectively you use LinkedIn for social selling across four dimensions.
What is LinkedIn SSI?
The Social Selling Index is LinkedIn's 0-100 score that measures your LinkedIn effectiveness across four pillars: establishing your professional brand, finding the right people, engaging with insights, and building relationships. It updates daily.
The Four SSI Pillars
| Pillar | What It Measures | Max Score |
|---|---|---|
| Professional Brand | Profile completeness, content publishing | 25 |
| Finding the Right People | Search usage, profile views | 25 |
| Engaging with Insights | Content sharing, commenting, reactions | 25 |
| Building Relationships | Connection growth, response rates | 25 |

This includes profile optimization, content engagement rhythms, and strategic connection building , all contributing to higher SSI and better outbound performance.
Frequently Asked Questions
- What is LinkedIn SSI?
- Social Selling Index (SSI) is a 0–100 score LinkedIn assigns based on four pillars: professional brand, finding the right people, engaging with insights, and building relationships.
- What is a good LinkedIn SSI score?
- Above 70 puts you in the top quarter of users; above 80 is rare. But SSI tracks LinkedIn-native behavior, not closed revenue - high SSI does not correlate with pipeline.
- Does LinkedIn SSI actually matter for sales?
- Marginally. SSI signals activity, not outcomes. Sales leaders who optimize for SSI usually generate more views and likes - not more qualified meetings. Outcomes come from targeting and message quality.
