What is Social Selling Index?
Also known as: SSI, LinkedIn SSI score
The Social Selling Index (SSI) is a LinkedIn score from 0 to 100 that measures how effectively you use LinkedIn to build a professional brand, find the right people, engage with insights, and build relationships. A higher SSI generally correlates with more room for outreach activity before LinkedIn applies limits.
LinkedIn calculates your SSI daily from four equally weighted pillars: establishing your professional brand, finding the right people, engaging with insights, and building relationships. Each is scored out of 25, for a total out of 100. You can see your own score for free at linkedin.com/sales/ssi.
SSI matters for outreach because accounts with a stronger presence and history tend to have more headroom for daily activity. A brand-new account with a low SSI that suddenly sends 100 connection requests a day is far more likely to get restricted than an established account with a high SSI doing the same volume.
A good SSI score is generally considered 70 or above, though what counts as good varies by industry. Rather than obsessing over the number, focus on the behaviors that raise it: complete your profile, post and engage genuinely, and build real relationships.
Weezly uses each connected account's SSI to set safe, per-account activity limits automatically, so a newer or lower-SSI account sends more conservatively than an established one. That is how the platform runs outreach at scale without tripping LinkedIn's restrictions.
Common questions
What is a good LinkedIn SSI score?
Generally 70 or above is considered good, and 80+ is strong. The average sits in the 30s to 40s for most professionals. More useful than the number is the trend: a rising SSI means your profile, engagement, and network are all improving.
