Silo Structure
Silo structure is a website architecture pattern that groups topically related content into isolated sections (silos), with strong internal linking within each silo and minimal cross-linking between silos.
In a strict silo structure, pages within a silo link only to other pages in the same silo and to the silo's category page. Cross-silo links are avoided to concentrate topical relevance. For example: a "Technical SEO" silo contains only technical SEO content, a "Content Strategy" silo contains only content strategy content, and they do not interlink.
The strict silo approach is debated in the SEO community. While it concentrates topical signals, it can create an unnatural internal linking structure and miss valuable contextual connections between related topics. Most modern SEO practitioners prefer a hybrid approach — strong thematic grouping with selective cross-linking where topically relevant.
In Next.js, silo structure maps naturally to your `app/` directory: `app/technical-seo/`, `app/content-strategy/`, `app/analytics/`. URL structure and internal links reinforce the silo boundaries while breadcrumbs and navigation provide the few cross-silo connections that are needed.
