Build Clusters

构建集群

Build a topical authority cluster from a seed keyword using pillar-spoke structure, coverage scoring, and interlinking plans.
基于种子关键词构建主题权威集群，涵盖支柱-辐条结构、覆盖度评分和内链规划。

What is a Topic Cluster?

什么是主题集群？

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
主题集群是一组相互链接的页面集合，共同覆盖某一主题领域。Google会在集群层面评估主题权威度——如果站点在该主题下没有支撑内容，单个页面的排名难度会高很多。
结构：
  • 支柱页（Pillar page）：对宽泛主题的全面概述（定位头部关键词）
  • 辐条页（Spoke pages）：聚焦子主题的专项文章（定位中端/长尾关键词）
  • 内部链接：所有辐条页都链向支柱页，支柱页链向所有辐条页，辐条页之间也互相交叉链接

Before You Start

开始前准备

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?
收集以下上下文信息（如果用户未提供可主动询问）：
  1. 种子主题。 需要搭建权威度的宽泛主题领域。
  2. 现有内容。 站点是否已经有该主题相关页面？请列出。
  3. 业务相关性。 该主题和产品或服务的关联是什么？
  4. 内容产能。 团队每月可产出多少篇内容？

Step 1: Subtopic Discovery

步骤1：子主题挖掘

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.
从种子主题出发，通过以下方法生成子主题：
搜索来源：
  • 种子关键词对应的People Also Ask问题
  • SERP底部的相关搜索
  • 自动补全建议（种子 + a、b、c…）
  • 竞品内容分析：排名靠前的站点都覆盖了哪些子主题？
意图来源：
  • 认知阶段："什么是[主题]"、"为什么[主题]很重要"
  • 考量阶段："最好的[主题]工具"、"[主题] vs [替代方案]"
  • 落地阶段："如何使用[主题]"、"[主题]教程"
  • 故障排查："[主题]无法运行"、"[主题]常见错误"
受众来源：
  • 受众关于该主题的入门级问题
  • 高级从业者的关切点
  • 决策者的评估标准
每个集群建议设置8-20个子主题。

Step 2: Cluster Map

步骤2：集群地图

Organize subtopics into a structured cluster:
Pillar: [Broad Topic] (head term)
│
├── Spoke: [Subtopic 1] (body term)
│   └── Intent: informational
│
├── Spoke: [Subtopic 2] (body term)
│   └── Intent: commercial investigation
│
├── Spoke: [Subtopic 3] (long-tail)
│   └── Intent: transactional
│
├── Spoke: [Subtopic 4] (long-tail)
│   └── Intent: informational
│
└── ... (8-15 more spokes)
将子主题整理为结构化的集群：
Pillar: [Broad Topic] (head term)
│
├── Spoke: [Subtopic 1] (body term)
│   └── Intent: informational
│
├── Spoke: [Subtopic 2] (body term)
│   └── Intent: commercial investigation
│
├── Spoke: [Subtopic 3] (long-tail)
│   └── Intent: transactional
│
├── Spoke: [Subtopic 4] (long-tail)
│   └── Intent: informational
│
└── ... (8-15 more spokes)

Step 3: Coverage Scoring

步骤3：覆盖度评分

Score how well the existing site covers the cluster:
SubtopicExisting Page?Quality (1-5)TrafficGap?
[subtopic 1]/blog/topic-14500/moNo
[subtopic 2]———Yes
[subtopic 3]/blog/old-post250/moPartial (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
评估现有站点对集群的覆盖程度：
子主题是否有现有页面？质量（1-5分）流量是否存在缺口？
[子主题 1]/blog/topic-14500/月否
[子主题 2]———是
[子主题 3]/blog/old-post250/月部分缺口（需要更新）
  • 完全缺口：无现有页面，需要新建
  • 部分缺口：页面存在，但内容单薄、过时或不符合用户意图
  • 已覆盖：现有页面质量较高，可能仅需补充内部链接

Step 4: Pillar Page Design

步骤4：支柱页设计

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.
支柱页应当满足以下要求：
  • 在概述层面全面覆盖主题（字数2000-4000字）
  • 链向所有辐条页，供用户深入阅读
  • 作为整个集群的目录结构存在
  • 定位集群中搜索量最高的关键词
  • 包含每个子主题的摘要（2-3段），并链向完整的辐条页
支柱页不是试图深度覆盖所有内容的超级文章，它是分发权威度、引导用户访问对应辐条页的枢纽。

Step 5: Interlinking Plan

步骤5：内链规划

Map the internal links:
From PageTo PageAnchor TextContext
PillarSpoke 1"[subtopic 1] guide"In the subtopic 1 overview section
Spoke 1Pillar"[broad topic]"In the introduction or conclusion
Spoke 1Spoke 2"[subtopic 2]"Where subtopic 2 is mentioned contextually
Spoke 3Spoke 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)
规划内部链接映射：
来源页面目标页面锚文本上下文位置
支柱页辐条页1"[子主题1]指南"在子主题1的概述部分
辐条页1支柱页"[宽泛主题]"在引言或结论部分
辐条页1辐条页2"[子主题2]"上下文提到子主题2的位置
辐条页3辐条页1"[子主题1]"适合做对比的位置
规则：
  • 所有辐条页必须链向支柱页（强制要求）
  • 支柱页必须链向所有辐条页（强制要求）
  • 辐条页可向2-4个同级辐条页添加交叉链接（上下文自然的前提下）
  • 使用多样化的锚文本（不要一直使用完全匹配的关键词）

Step 6: Cluster Health Metrics

步骤6：集群健康度指标

Score the cluster's readiness to compete:
Coverage Score  = (Covered spokes / Total spokes) x 100
Link Health     = (Spokes with bidirectional pillar link / Total spokes) x 100
Content Quality = (Spokes scoring 3+ quality / Total spokes) x 100
MetricScoreThreshold
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
评估集群的排名竞争力：
Coverage Score  = (Covered spokes / Total spokes) x 100
Link Health     = (Spokes with bidirectional pillar link / Total spokes) x 100
Content Quality = (Spokes scoring 3+ quality / Total spokes) x 100
指标得分阈值
覆盖度[x]%超过70%可开始冲击支柱页关键词排名
链接健康度[x]%目标为100%——所有辐条页都必须和支柱页互链
内容质量[x]%超过80%——辐条页内容单薄会稀释集群权威度

Expected Outcomes by Health Level

不同健康度对应的预期效果

Cluster StateCoverageLink HealthContent QualityExpected Result
Incomplete<50%<70%AnyPillar unlikely to rank page 1; spokes rank individually at best

Competitive70-90%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
集群状态覆盖度链接健康度内容质量预期结果

Internal Link Standards per Cluster

每个集群的内链标准

Link TypeMinimum CountDirection
Pillar → each spoke1 per spokeDownward — link from the relevant section of the pillar
Each spoke → pillar1 per spokeUpward — "our complete [topic] guide"
Spoke ↔ sibling spokes2-4 per spokeLateral — where contextually natural
Cross-cluster bridges0-2 per clusterBetween 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.
链接类型最低数量方向
支柱页 → 每个辐条页每个辐条页1条向下——从支柱页对应子主题的部分链出
每个辐条页 → 支柱页每个辐条页1条向上——锚文本类似"我们的完整[主题]指南"
辐条页 ↔ 同级辐条页每个辐条页2-4条横向——上下文自然的前提下
跨集群桥接链接每个集群0-2条枢纽间——仅当存在真实主题相关性时添加
具备排名竞争力的集群标准： 覆盖度>70%、链接健康度=100%、内容质量>80%。低于这些阈值时，请优先填补缺口，再期待支柱页获得排名。

Step 7: Production Sequence

步骤7：产出顺序

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
按以下顺序安排内容生产，实现效果最大化：
  1. 优先制作支柱页——即使是草稿版本，也能先搭建好枢纽
  2. 接下来产出机会最高的辐条页——定位缺口、机会评分最高的页面
  3. 更新现有辐条页——更新并重新链接所有存在部分缺口的页面
  4. 剩余辐条页——逐步完善集群内容
  5. 更新支柱页——每发布一篇新辐条页，就给支柱页添加对应链接
