Siloing Your Website
[]Updated in 2026: The original article treated siloing as a ranking technique. The useful part is simpler: a clear site structure helps people and crawlers understand how pages relate to one another.
Website structure should help a reader move from a broad subject to the detail that answers their question. It does not need artificial barriers between parts of the site.
Build a hierarchy around the reader’s task
Start with the subjects the site genuinely covers. Group related pages under a clear category or topic hub, then link to the detailed guides, products or case material that support that subject.
A useful topic hub does more than list links. It explains the scope of the subject, distinguishes nearby topics and gives the reader a sensible next step. The hub becomes the place to orient yourself; the detail pages do the actual work.
This is information architecture, not a promise of a particular ranking. Google’s guide to how Search works separates discovery, indexing and serving results. A tidy hierarchy can make the site’s relationships easier to interpret, but it cannot force a page into the results.
Link where the next step is useful
A link belongs in a page when it continues the reader’s current task. A guide about choosing a product can link to the relevant comparison and the supporting technical explanation. A topic hub can link to both without pretending that the pages are isolated from one another.
Use wording that tells people what they will find. Google describes crawlable links as ordinary links with a destination that can be discovered and followed. The link text is navigation copy, not a scoring exercise. Do not force the same phrase into every link or add a link that has no reader-facing reason to exist.
Cross-links between related subjects are often useful. A page about a database migration may need to point to backup design, security or operational ownership. Blocking those connections to preserve a supposed silo makes the site harder to use and hides the real shape of the subject.
What not to turn into architecture
Tags, filters and search results can help people find material, but they are not automatically useful sections of a site. Keep them when they have a clear audience, stable labels and maintained results. Do not create a new route for every variation of a phrase.
Subdomains are delivery and ownership choices. They can make sense for a separate application, security boundary or independently operated publication. Creating one simply to place a topic in its own search container adds another boundary to maintain without explaining the subject better.
The same test applies to navigation automation: inspect the links it produces, remove dead ends and keep the important routes visible in ordinary HTML. A generated list is not a substitute for deciding which pages belong together.
Audit the structure as a reader would
A practical review asks:
- Can a new reader understand what each major section covers?
- Can they reach every important page through ordinary links?
- Does each page have a clear parent, or is it orphaned?
- Are the links between related subjects present when they help the task?
- Do filters, parameters or alternate URLs create pages that compete with the intended canonical page?
Fix the reader’s path first. Then inspect crawl data, server responses and the rendered HTML to find technical problems. The structure is doing its job when it makes the site’s subjects, boundaries and next steps obvious without requiring a ranking theory to explain it.
