LinkedIn content authority is building audience and credibility through consistent, valuable posting. Creators share insights, articles, videos, and engage with community. The algorithm rewards native content (posts, videos) over links. High-engagement posts reach 10k-100k+ people. Followers include prospects (for sales), employees (for recruiting), and peers (for learning). Authority compounds: starting slow, then accelerating. Early posts get 10-50 views. Viral posts (relatable, insightful, contrarian) get 10k+. Consistency builds audience.
