SSI Benchmarks

Market Comparison

40-60	Average
60-75	Above average
75-100	Top performers

By Industry

LinkedIn shows how you compare to:

• People in your industry
• People in your network

Does SSI Affect the Algorithm?

What We Know

LinkedIn has never confirmed that SSI affects reach.

Correlation vs. Causation

People with high SSI:

• Are more active
• Post more
• Engage more
• Get more reach

But: it may be that activity drives SSI, not that SSI drives reach.

Practical Conclusion

Use SSI as a diagnostic, not as a goal. If all 4 pillars are low, improve them—that naturally improves results.

Common Mistakes

1. Focusing Only on the Score

2. Gamifying Without Purpose

Connecting with anyone just to increase the number.

3. Ignoring Quality

100 relevant connections > 1000 random ones.

4. Not Maintaining

SSI drops if you stop using the platform actively.
