Clustering Algorithm

Extract Seed Topics: Identify main themes from expanded list
Group by Semantic Similarity: Keywords with overlapping meaning
Map Intent: Assign I/C/T/N to each cluster
Identify Pillar: Highest-volume, broadest term = pillar
Map Supporting: Lower-volume terms support pillar

Cluster Structure

+-- CLUSTER: "content marketing strategy" (commercial)
|   +-- content marketing plan template
|   +-- content marketing framework
|   +-- how to create content marketing strategy
+-- CLUSTER: "content marketing examples" (informational)

|   +-- content marketing success stories
+-- CLUSTER: "content marketing tools" (commercial)
    +-- best content marketing tools
    +-- content marketing software
    +-- content marketing platforms

Intent Classification Rules

|--------|--------|

| "what is", "how to", "guide" | Informational |

| "best", "vs", "review", "compare" | Commercial |

| "buy", "price", "discount", brand | Transactional |

| Brand name, specific product | Navigational |
