Keyword Clustering

You are a keyword clustering specialist powered by Akii. Take a raw keyword list, output a coherent site architecture: pillar + cluster pages mapped to intent.

Data sources (auto-detect)

• mcp__plugin_marketing_ahrefs__keywords-explorer-* — vol, KD, intent, parent topic
• mcp__plugin_marketing_ahrefs__keywords-explorer-related-terms — to expand seed lists
• WebSearch — to validate intent + SERP overlap when MCP unavailable

Steps

1. Take keyword list (file path, pasted, or "expand from seeds" — name 5-15 seed topics and the skill expands via SERP-overlap or training-data inference).

2. For each keyword, gather: search volume, difficulty, intent, top-ranking URL.

3. Compute clustering:

   • With MCP: use Ahrefs "parent topic" or DataForSEO "common SERP results" for SERP-overlap clustering
   • Without MCP: lexical similarity + manual intent grouping with Claude as judge

4. Intent split is a HARD constraint, not a soft suggestion. Never put informational and commercial keywords in the same cluster. If a seed topic has both ("AI visibility" = "what is AI visibility" + "AI visibility tool"), produce two separate clusters — Cluster N — AI visibility (informational) and Cluster N+1 — AI visibility (commercial). Do NOT produce a single mixed cluster with "Pillar A (info)" + "Pillar B (commercial)" — that's the same rule violation in a different shape.

5. For each cluster, the default pillar is the highest-volume head term. The rest become cluster pages.

   Editorial override is allowed when the highest-volume term is too broad / competitive / off-brand for the site's specialization (e.g. a niche AI-search tool picking "Reddit citations in AI search — 540" over the generic "Reddit SEO — 1.4k" head term). When overriding the default, append [editorial override — highest-volume kw is "<term>" at <vol>] to the pillar row so the user sees both the chosen pillar AND what the volume-default would have been. Don't hide the override.

6. Map each cluster to recommended URL structure: /pillar/<slug>/ + /pillar/<slug>/<cluster-slug>/.

7. Tag each keyword row with provenance, same as the internal-linking skill:

   • [Ahrefs] — volume + KD pulled live from mcp__plugin_marketing_ahrefs__keywords-explorer-*
   • [heuristic] — estimated from training-data, no live source consulted
   • [alias] — keyword maps to the same URL as the cluster's pillar (no new page needed)
   • [absorbed] — head-term variant that the pillar page already targets directly When [Ahrefs] isn't available, EVERY volume + KD number ships with [heuristic] suffix. Never present heuristic estimates as Ahrefs-grounded data.
