What Is a Silo Structure?
Silo structure is an information architecture method that groups related website pages into clear subject areas. Each group has a central page supported by closely related pages, with internal links showing their relationship. For a law firm website, the structure can separate practice areas, legal services, locations and supporting guidance.

How Silo structure Works

A Silo structure assigns pages to clear subject groups. A central page introduces the main topic, while supporting pages address narrower questions or services. Internal links connect these pages and help users move through related information without losing context.

On a law firm website, a practice area can act as a central topic, with service pages and educational articles supporting it. The structure is checked by reviewing page relationships, link destinations and URL patterns. Internal linking gives each connection a purpose, such as guiding a reader from a family law overview to information about parenting arrangements.

Expert Note
When we work on-Page SEO For Law Firms, we map practice areas, services and supporting articles into logical groups. We check that each page has a clear role and that internal links reflect genuine subject relationships. We also look for overlapping pages that could confuse users or weaken the site structure.
Silo structure in Practice: A Real-World Example
A family law website may place its family law page at the centre of one silo. Child custody, property settlement and divorce pages can support that topic, with links connecting each page to the relevant service and guidance.
