What is the LinkedIn SSI score and how do I improve it?

SSI (Social Selling Index) measures your LinkedIn activity across 4 dimensions: building a professional brand, finding the right contacts, engaging through insights, nurturing relationships. Important for job seekers: More active profiles are favoured by the algorithm and more visible to recruiters. Improvement: Leave 1 comment daily, publish 1 post weekly, complete your profile to 100%, build at least 500 connections.
