TL;DR: Create one main “hub” page for a topic, then write supporting pages that answer specific questions. Interlink them so Google (and readers) see the full topic covered.

What A Topic Cluster Is

A topic cluster is a group of pages about one subject that are connected through internal links.

Basic Cluster Structure

• Hub page: broad overview (the main resource)
• Support pages: narrow, specific answers (the how-tos and FAQs)

How To Build One (Step-by-Step):

1. Pick a topic you want to be known for (example: “Indexing and crawlability”).
2. Create a hub page that covers the full overview.
3. Create 6–15 supporting articles that answer related questions.
4. Link every supporting article back to the hub.
5. From the hub, link out to every supporting article.

Linking Best Practices

• Use contextual links in the body, not just a list of links at the bottom.
• Keep the cluster tight (don’t link to unrelated topics unless it truly helps).
