Retrieval Depth

Definition

Retrieval Depth refers to how far down an AI system searches within its candidate results before selecting passages for answer synthesis. Greater depth increases the likelihood of secondary sources being included in generative outputs.

Why It Matters

Shallow retrieval may favor dominant domains and limit emerging brand visibility.

How It Works

AI systems retrieve a ranked list of passages, and depth determines how many candidates are evaluated before final ranking.

Best Practices

  • Strengthen semantic clarity
  • Improve entity authority
