Silo Structure
A site architecture method that groups related content into themed categories.
Definition
A silo structure is a website architecture strategy that organizes pages into distinct topical categories — grouping all related content together and ensuring that internal links flow primarily within each silo. Each silo signals concentrated topical authority to search engines for that specific subject.
Why It Matters
Search engines reward topical authority. A well-structured content silo tells Google that your site is a genuine authority on a topic because all relevant content is grouped and well-interlinked.
Examples
Writing tools siloAll word count, character count, and readability tools grouped under /writing-tools/
SEO tools siloMeta description, title tag, and slug tools grouped under /seo-tools/
Glossary siloAll definition pages grouped under /glossary/ with rich internal cross-linking
Common Mistakes
Linking heavily between unrelated silos.
Creating silos that are too narrow.
Not maintaining the silo with new content.
Confusing physical URL structure with logical silo structure.
