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):
1. Seed topic. The broad subject area to build authority around.
2. Existing content. Does the site already have pages on this topic? List them.
3. Business relevance. How does this topic connect to the product or service?
4. Content capacity. How many pieces can the team produce per month?
Step 1: Subtopic Discovery
From the seed topic, generate subtopics using these methods:
Search derived:
People Also Ask questions for the seed keyword
Related searches at the bottom of SERPs
Autocomplete suggestions (seed + a, b, c...)
Competitor content analysis — what subtopics do top ranking sites cover?
Intent derived:
Awareness: "what is [topic]", "why [topic] matters"
Consideration: "best [topic] tools", "[topic] vs [alternative]"
Implementation: "how to [topic]", "[topic] tutorial"
Troubleshooting: "[topic] not working", "common [topic] mistakes"
Audience derived:
Beginner questions about the topic
Advanced practitioner concerns
Decision maker evaluation criteria
Aim for 8 20 subtopics per cluster.
Step 2: Cluster Map
Organize subtopics into a structured cluster:
Step 3: Coverage Scoring
Score how well the existing site covers the cluster:
Subtopic Existing Page? Quality (1 5) Traffic Gap?
[subtopic 1] /blog/topic 1 4 500/mo No
[subtopic 2] — — — Yes
[subtopic 3] /blog/old post 2 50/mo Partial (needs refresh)
Full gap — no existing page, needs creation
Partial gap — page exists but is thin, outdated, or off intent
Covered — strong existing page, may just need internal linking
Step 4: Pillar Page Design
The pillar page should:
Cover the topic comprehensively at an overview level (2,000 4,000 words)
Link to every spoke page for deeper dives
Be structured as a table of contents for the entire cluster
Target the highest volume keyword in the cluster
Include a summary of each subtopic (2 3 paragraphs) with a link to the full spoke
Pillar page is NOT a mega article that tries to cover everything in depth. It is a hub that distributes authority and directs readers to the right spoke.
Step 5: Interlinking Plan
Map the internal links:
From Page To Page Anchor Text Context
Pillar Spoke 1 "[subtopic 1] guide" In the subtopic 1 overview section
Spoke 1 Pillar "[broad topic]" In the introduction or conclusion
Spoke 1 Spoke 2 "[subtopic 2]" Where subtopic 2 is mentioned contextually
Spoke 3 Spoke 1 "[subtopic 1]" Where comparison is relevant
Rules:
Every spoke links to the pillar (mandatory)
Pillar links to every spoke (mandatory)
Spokes cross link to 2 4 siblings (where contextually natural)
Use varied anchor text (not always the exact keyword)
Step 6: Cluster Health Metrics
Score the cluster's readiness to compete:
Metric Score Threshold
Coverage [x]% 70% to start ranking for pillar keyword
Link Health [x]% 100% is the target — every spoke must link to pillar and back
Content Quality [x]% 80% — clusters with thin spokes dilute authority
Expected Outcomes by Health Level
Cluster State Coverage Link Health Content Quality Expected Result
Incomplete <50% <70% Any Pillar unlikely to rank page 1; spokes rank individually at best
Developing 50 70% 70 90% 50 80% Pillar may appear page 2 3; some spokes rank for long tail
Competitive 70 90% 100% 80 90% Pillar competes for page 1; most spokes rank for their targets
Dominant 90% 100% 90% Pillar strong on page 1; cluster captures most queries in the topic
Internal Link Standards per Cluster
Link Type Minimum Count Direction
Pillar → each spoke 1 per spoke Downward — link from the relevant section of the pillar
Each spoke → pillar 1 per spoke Upward — "our complete [topic] guide"
Spoke ↔ sibling spokes 2 4 per spoke Lateral — where contextually natural
Cross cluster bridges 0 2 per cluster Between hubs — only with genuine topical relevance
Cluster ready to compete: Coverage 70%, Link Health = 100%, Content Quality 80%.
Below these thresholds, prioritize filling gaps before expecting the pillar to rank.
Step 7: Production Sequence
Order the content production for maximum impact:
1. Pillar page first — even as a draft, it establishes the hub
2. Highest opportunity spokes next — pages targeting gaps with the best opportunity scores
3. Refresh existing spokes — update and relink any partial gap pages
4. Remaining spokes — fill out the cluster over time
5. Update pillar — add links to each new spoke as it's published
Output Format
Topic Cluster: [seed topic]
Cluster Summary
Pillar keyword: [keyword] (volume: [x], difficulty: [y])
Total spokes: [count]
Existing coverage: [x]% ([n] pages exist, [n] need creation)
Total cluster volume: [sum of all keyword volumes]
