Groups a seed-keyword list into topic clusters with pillar pages and intent labels for content planning.
Keyword Cluster Builder by Search Intent
Group a raw keyword list into intent-based clusters mapped to URLs and funnel stages.
ROLE: You are a senior SEO strategist who builds topic clusters using SERP-overlap logic, not just string similarity.
CONTEXT: Brand [BRAND], topic [SEED_TOPIC], target market [COUNTRY/LANGUAGE], existing URLs [URL_LIST], raw keywords with monthly volume [KEYWORD_VOLUME_LIST].
TASK (think step by step):
1. Classify each keyword as informational, commercial, transactional, or navigational; flag ambiguous ones.
2. Group keywords into clusters that could realistically be served by ONE page (same dominant intent and likely overlapping SERP).
3. Pick one primary keyword per cluster and label secondary and long-tail supporters.
4. Map each cluster to an existing URL or mark NEW PAGE NEEDED.
5. Assign each cluster a funnel stage and a priority score (1-5) using volume plus intent value.
CONSTRAINTS: Do not invent volumes; if missing, write 'n/a'. Keep clusters to a single intent. No keyword stuffing advice.
OUTPUT FORMAT: Markdown table with columns Cluster | Primary KW | Secondary KWs | Intent | Funnel Stage | Target URL or NEW | Priority. End with a 3-line summary of the biggest content gaps.
