What Is LinkedIn's Social Selling Index (SSI)?
Also known as SSI, LinkedIn SSI, LinkedIn Social Selling Index, SSI score
The Social Selling Index (SSI) is a LinkedIn score from 0 to 100 that measures how effectively a member uses LinkedIn for selling. It is built from four equally weighted pillars: establishing a professional brand, finding the right people, engaging with insights, and building relationships. LinkedIn updates the score daily.
Social Selling Index (SSI) explained
Each of the four pillars is worth up to 25 points. Professional brand looks at your profile completeness and publishing. Finding the right people reflects how you search for and view relevant prospects. Engaging with insights covers sharing and interacting with content. Building relationships reflects connecting with and strengthening ties to decision-makers. LinkedIn also shows how you rank against your industry and network.
Any member can check their SSI from LinkedIn's Social Selling Index page while logged in; you do not need Sales Navigator, although some of its activities feed the score. LinkedIn does not publish the exact calculation, so treat the score as a rough directional signal rather than a precise measurement.
SSI is useful as a habit tracker. A low score in one pillar shows where your LinkedIn activity is thin, such as no posting or no searches for new prospects. It is not a revenue metric. A rep with a high SSI and no meetings is busy, not effective, so pair it with acceptance rate, reply rate and pipeline.
Social Selling Index (SSI) example
A new account executive checks her SSI and sees 38. Her brand pillar is low because her profile has no About section or posts, and her relationships pillar is weak because she rarely connects with senior people. Over six weeks she rewrites her profile, posts once a week, uses Sales Navigator searches, and connects with 15 relevant directors each week. Her score climbs into the 60s, and her acceptance rate rises too.

Common mistakes
- Treating SSI as a sales target and gaming it with low-value activity that produces no conversations.
- Comparing SSI across reps with very different territories, roles or network sizes.
- Connecting with random people to raise the score, which dilutes your network and your feed.
- Checking the score daily and reacting to small swings that mean very little.
Social Selling Index (SSI) FAQ
LinkedIn does not define a good score. Many practitioners see scores in the 70s and above as a sign of strong, consistent activity, but the number matters less than whether your LinkedIn work produces conversations and meetings. Use your industry and network rank as a rough comparison.
No. Any LinkedIn member can view their SSI from LinkedIn's Social Selling Index page while logged in. Sales Navigator activity, like saving leads and running searches, can contribute to the score, but you do not need a subscription to see it.
LinkedIn updates the Social Selling Index daily, based on your recent activity. Because it reflects ongoing behavior, the score drops if you stop posting, searching or connecting for a while, and rises again as activity picks up.
LinkedIn has not said SSI is used to rank posts or boost reach. The habits that raise it, such as a complete profile, regular posting and genuine engagement, tend to help visibility on their own, so the two often move together.
