Summary

LinkedIn is the #2 most cited domain in AI search responses. Analysis of 89 000 unique LinkedIn URLs across 325 000 prompts shows that original, educational content in the 500-2 000 word range gets cited regardless of follower count or viral engagement. Relevance and authority beat popularity.

Key Insight

  • LinkedIn dominance in AI citations: #2 most cited domain overall - ChatGPT Search 14,3%, Google AI Mode 13,5%, Perplexity 5,3% (11% average across all three)
  • High semantic fidelity: AI echoes LinkedIn content more faithfully (similarity 0,57-0,60) than Reddit (0,53-0,54) or Quora (0,435) - meaning LinkedIn content shapes AI answers more directly
  • Original content wins: ~95% of cited content is original; reshares account for just 5%. Articles make up 50-66% of citations, feed posts 15-28%
  • Optimal length: Articles 500-2 000 words, posts 50-299 words. Long-form educational content is the sweet spot
  • Educational/advice content dominates: 54-64% of all cited content focuses on sharing knowledge or practical advice
  • Company vs individual split varies by platform: Perplexity favours company pages (59%), while ChatGPT Search and Google AI Mode favour individual profiles (59%)
  • Posting frequency matters: ~75% of cited authors post 5+ times per 4-week period
  • Follower count is not a barrier: Nearly half of cited authors have 2 000+ followers, but creators with <500 followers are just as likely to be cited if content is authoritative
  • Engagement threshold is low: Median cited post has 15-25 reactions and no more than 1 comment. Virality is not required - relevance wins
