Social Selling Index

A LinkedIn metric that summarizes how effectively an account uses the platform to build a professional brand, find the right people, engage with insights, and grow relationships; presented as a composite score across these activity areas.

The Social Selling Index (SSI) is LinkedIn’s composite indicator of how well an individual or account uses the platform for professional networking and sales-related activities. It aggregates performance across several activity areas—commonly including profile strength, network building, content engagement, and relationship development—into a single score.

For LinkedIn creators, SSI matters because it provides a compact signal about discoverability and outreach effectiveness. A stronger SSI often correlates with better visibility in searches, greater trust from prospects, and clearer priorities for where to focus time—whether that is tightening a profile, growing relevant connections, or increasing meaningful engagement.

Top Voice helps creators interpret and act on SSI insights by making the underlying components more visible and by highlighting practical areas to focus attention. Rather than treating the score as an endpoint, Top Voice encourages creators to use SSI trends to shape content strategy, community engagement, and networking priorities.

Use SSI as one diagnostic among several metrics. Track changes over time, compare component trends, and combine SSI signals with direct engagement and conversion data to form a fuller picture of how LinkedIn activity is supporting your creator goals.
