Build Clusters

This walks you through building a proper topic cluster from a seed keyword: pillar page targeting the head term, 8-20 spoke pages covering subtopics, and the bidirectional linking structure Google actually rewards. It scores your existing coverage, helps you prioritize which gaps to fill first, and gives you health metrics (coverage, link health, content quality) so you know when the cluster is actually ready to compete. The output is a production roadmap with an interlinking plan, not just a list of article ideas. Use it when you're trying to rank for a competitive keyword and need the supporting content architecture, not when you just need one blog post.

Build Clusters

Build a topical authority cluster from a seed keyword using pillar-spoke structure, coverage scoring, and interlinking plans.

What is a Topic Cluster?

A topic cluster is a group of interlinked pages that collectively cover a subject area. Google evaluates topical authority at the cluster level — ranking a single page is harder if the site has no supporting content around the topic.

Structure:

Pillar page — comprehensive overview of the broad topic (targets head term)
Spoke pages — focused articles covering subtopics (target body/long-tail terms)
Internal links — every spoke links to the pillar, pillar links to all spokes, spokes cross-link to siblings

Before You Start

Gather this context (ask if not provided):

Seed topic. The broad subject area to build authority around.
Existing content. Does the site already have pages on this topic? List them.
Business relevance. How does this topic connect to the product or service?
Content capacity. How many pieces can the team produce per month?
