What problem does it solve? Keyword clustering alone cannot tell you which terms are actually worth targeting. This Skill validates real search demand and competitive difficulty against the live SERP, prunes weak or unwinnable terms, and consolidates the survivors into a confirmed topic list with target keywords. ## Core Features & Use Cases - Manual demand validation (HITL): Reviews the actual SERP for each candidate term via WebSearch/WebFetch to confirm real competition and searcher intent. - Competitor review table: Fills a structured rubric (top results, common patterns, depth threshold, difficulty, gaps, winning edge, verdict) per target keyword using ./references/competitor-review-table.md. - Term pruning and topic convergence: Cuts low-demand or too-difficult terms, merges same-intent terms into one topic, and outputs SEO_PACKET ▸ Topics for handoff to seo-brief-writer. - Use Case: After seo-keyword-classifier delivers a Classified packet, run this stage to confirm which of 40 clustered keywords survive SERP validation and converge into 8 article topics with primary and supporting keywords. ## Quick Start Hand over the Classified SEO packet and say 「驗證需求」 to validate demand and organize the topic list.
