Research before a decision
Widen recall so the answer is not decided by whichever page ranks first.
Deep tiers widen recall so the answer is not decided by whichever source happens to rank first. Useful when being wrong is expensive and you need the coverage to be defensible.
- Deeper tiers query more sources, so coverage does not depend on one engine's opinion.
- Agreement between independent sources becomes a ranking signal instead of a duplicate result.
- Every request is itemised in your history with its tier and exact cost, which matters when the research is billable.
Consensus between independent sources is its own signal, so agreement across the web counts for more than one confident page.
