Once your pillar page is in place, it’s time to start developing the topic clusters, or subpages and blogs, that will provide more details about that topic. These are supplemental materials that support your pillar page. A subpage provides the opportunity to expand on what you’ve highlighted on your pillar page. It also needs to be fairly comprehensive—think 2500 words. These subpages take the form of text, infographics, videos, a guidebook or ebook. This is where you get creative and attract your users. They can be fun and entertaining, and tell a story.
