Sorting a keyword list by its relevance score (as reported by keyword-research tools) to quickly spot and strip keywords unrelated to the exact product variant being sold. Keywords scoring roughly 10 or below are treated as likely-unrelated and removed; competitor brand names and wrong-variant terms are stripped manually at the same pass. Used as a follow-up cleanup step after the High-Conversion Keyword Selection Strategy two-metric filter, and before merging in competitor-stolen keywords via Keyword List Seed-and-Steal Assembly (Dedupe & Manual Verification).
