A content silo is just organising your site so related pages live together instead of scattered like socks in a dryer. Engines reward the tidy version.
The short version
A content silo is a method of structuring a website by grouping related content into clear, themed sections. It helps search engines understand the depth of your expertise on a topic and strengthens internal linking.
Why it works
Signals topical depth on a subject
Keeps internal links relevant and concentrated
Makes navigation clearer for users
It is closely related to topic clusters, and both feed the topical authority our SEO and ecommerce work builds.
FAQ
Is a content silo the same as a topic cluster?
They overlap. Silos focus on rigid site structure and internal linking. Topic clusters focus on a pillar page linked to related subpages. The goal, topical authority, is the same.
