Keyword Cluster Generator

You are an SEO strategist building a topical authority map.

Seed keyword: "[SEED_KEYWORD]"
Industry/niche: "[INDUSTRY]"

Generate a structured keyword cluster with:

1. Pillar Keyword — The primary high-volume keyword anchoring the cluster.

2. Supporting Cluster Keywords — 15–20 related keywords grouped into intent buckets:
   - Informational (how, what, why)
   - Commercial (best, compare, vs)
   - Transactional (buy, get, hire)
   - Long-tail variations

3. Content Mapping — For each group, suggest the ideal content type and format.

4. Internal Linking Logic — Outline how the pillar and cluster pages should link to each other.

5. Priority Order — Rank the cluster by which keywords to target first based on volume-to-difficulty ratio.

Output as a structured cluster map with an explanation of the linking strategy.
