SSI (Social Selling Index)
LinkedIn's 0-100 score that measures how effectively a profile sells on LinkedIn.
Definition
Social Selling Index (SSI) is LinkedIn's measure of four behaviours: establishing your professional brand, finding the right people, engaging with insights, and building relationships. Scores above 70 correlate with measurably better organic reach, connection acceptance and reply rates.
Why it matters
SSI is one of the few visible signals of LinkedIn account warmth. Lifting SSI before launching outbound improves performance across every metric.
