KR1 is responsible for “discovery” and not final screening.
KR1 What to expand?
- Scene expression
- Expression of constraints
- Conversational expression
- Semantic variants
Why is this step critical?
Amazon’s on-site search continues to incorporate more natural expressions of intent, especially in AI shopping interaction scenarios.
Execution process
- Enter a set of focused competitive product ASINs
- Generate multi-intent cluster candidate words in Keyword Mining
- Incorporate external etymologies as needed
- Send the full amount to Keyword Refiner for verification
Practical principles
The KR1 stage pursues "maximization of coverage quality", not premature filtering.
