Topic Clusters SEO
Topic Clusters SEO is an SEO topic covered in SeoWiki.
Key takeaways
- A topic cluster uses a pillar page as the central hub and cluster content as supporting pages on related subtopics.
- Cluster pages should be linked to the pillar page, and related cluster pages should also be cross-linked where relevant.
- The pillar page usually covers the topic broadly, while cluster pages answer narrower questions, use cases, or long-tail searches.
Topic clusters help search engines and users understand a site’s topical coverage by grouping related content around one central theme. For SEO practitioners, they improve internal linking, content planning, and the ability to build authority around high-value topics instead of publishing isolated articles.
