What is a Topic Cluster and Pillar Page?

A topic cluster is a way of structuring content around one main topic: a comprehensive pillar page on the central theme, surrounded by in-depth articles on subtopics that link to each other. This structure helps search engines see your authority on a theme and strengthens the coherence within your site.

Pillar page and cluster pages

The pillar page gives a broad overview of a main topic and links to more specific cluster pages, each of which covers a subtopic in depth. Those cluster pages link back to the pillar. That creates a network of connected internal links.

Why do topic clusters work?

By grouping content around a theme, you show search engines that you cover a topic thoroughly. That strengthens your topical authority and helps several pages rank. It fits neatly with your broader content strategy.

Building a topic cluster

Choose a main topic with enough search demand, determine the subtopics through keyword research and create a page per subtopic. Make sure everything links logically around the pillar page.

What is the difference between a pillar page and a cluster?

The pillar page is the broad overview; cluster pages cover specific subtopics and link back to it.

How many cluster pages do you need?

As many as you need to cover the topic properly; quality and coverage matter more than a fixed number.
