  • The tier 3 review and comparison layer (positions 16-25)
  • The tier 4 vertical authority layer (positions 26-40)
  • The tier 5 community and niche layer (positions 41-50)
  • The engine-by-engine breakdown
  • What is not on this list (and why)
  • How the rankings actually change
  • The operator playbook: where to start
  • What to do if your category is not here
  • Place brand mentions inside the 50 domains above
  • Frequently asked questions
