Social Selling Index (SSI)
LinkedIn's 0–100 score of how actively and credibly you use the platform, across four pillars: professional brand, finding the right people, engaging with insights, and building relationships.
SSI matters to outbound for one practical reason: accounts with stronger engagement history appear to earn more platform tolerance — the higher end of the invitation range is generally reported by older, active, high-SSI accounts. You raise it boringly: post occasionally, comment genuinely, keep your profile complete. Check yours at linkedin.com/sales/ssi.
