SEO siloing: when structure helps and when it gets in the way
[]SEO siloing is a way to plan related pages around a subject. It becomes unhelpful when the planning model is treated as a law of navigation. This post is for technical site owners and editors who need to organise content without creating artificial separation between useful pages.
The idea is straightforward. Group related pages so that a visitor, an editor and a search crawler can tell what belongs together. Problems start when the diagram becomes a set of rules: pages in one silo must never link to another, menus must reproduce the diagram, and every internal link needs a permission slip.
A visitor doesn’t care whether two pages belong to different boxes in an SEO presentation. They care whether the next page helps answer the question that brought them there.
Plan around the questions
Siloing can help you plan a site. Start with a subject, identify the questions around it, and decide which page should answer each one. The result might be a hierarchy with one durable overview, several narrower explanations and supporting pages. It might also be a hub with links in several directions.
Google’s SEO Starter Guide makes a similar, narrower point: logical organisation can help users and search engines understand how pages relate. It also cautions against reorganising an established site without a practical reason. Structure is a means of explanation, not a ranking requirement.
For a small site, that planning model may produce the following.
- one page that defines the subject;
- supporting pages for distinct questions;
- navigation that exposes the important route;
- descriptive titles, headings and links;
- a sensible next step for a reader who wants more detail.
The structure should emerge from the content and the reader’s questions. Do not create a page merely because a keyword appears in a spreadsheet. If two proposed pages would have the same purpose, combine them rather than manufacturing a second introduction.
Keep page hierarchy and internal links distinct
A URL hierarchy answers one question: where does this page sit? Internal links answer another: what might help the reader next? The two influence one another, but they are not the same thing.
A page about crawling may need to explain indexing. A page about local search may need to explain reviews. A page about a product may need to link to documentation, pricing, limitations and support. Those links can be correct even when an old silo diagram places the subjects in separate branches.
Google’s link best-practices documentation recommends crawlable links with descriptive, concise anchor text. It also says there is no magical ideal number of links. Link when the relationship is useful, and make that relationship legible rather than trying to link everywhere.
A good link names the destination and gives the reader a reason to leave the current page. It also sets an accurate expectation about what comes next. “Read our local reviews guide” is more useful than “click here”, but it is only a good link if the destination really is a local reviews guide.
Review each internal link
For each proposed internal link, ask six questions.
- What might the reader need at this sentence?
- Does the linked page answer that need more directly than the current page can?
- Does the surrounding sentence explain the relationship?
- Would the link make sense if someone saw only its visible text?
- Will the destination remain useful, or is this a temporary page, campaign or duplicate?
- After following it, can the reader continue without having to reconstruct the site map?
This is a relevance test rather than a score. A link can be valuable because it prevents confusion, supplies a definition, supports a decision or provides a primary source. It does not need to cross a search-volume threshold.
A link ledger can make the review concrete.
| Source page | Destination | Reader need | Why this anchor text? | Review date |
|---|---|---|---|---|
| Service overview | Setup guide | Understand the first step | Names the guide | 23 July 2026 |
| Crawling explanation | Indexing explanation | Distinguish two mechanisms | Names the distinction | 23 July 2026 |
The dates in this example are review dates, not performance claims. The ledger exposes forced links and forgotten destinations.
Do not create pages to complete a pattern
A silo becomes harmful when it encourages pages that exist only to complete a pattern. Warning signs include thin category pages, repeated introductions, location pages that differ only by a place name, and a navigation menu that reflects an internal org chart rather than the reader’s task.
Google’s spam policies describe doorway abuse as creating similar pages for specific queries that funnel users towards one destination. That is a useful reason to be cautious with geographic or keyword-shaped page sets. The question is whether each page has a distinct job and gives the visitor something useful, not whether a folder is tidy.
The same caution applies to URL paths. A tidy hierarchy can help people understand where they are. Changing URLs to make a diagram look cleaner can create redirects, broken links, stale bookmarks and migration work. Improve the information architecture when the current structure prevents people finding things. Do not change a stable URL simply to satisfy a metaphor.
Let readers test the structure
One practical test for a structure is a short usability exercise. Give someone a page and ask the following questions.
- What is this page about?
- What question does it answer?
- What would you expect to find next?
- Which link would you follow, and why?
- Is any important related explanation missing?
There is no need to turn this into a ranking experiment. The answers show whether the page has a clear purpose and whether its relationships are visible. Search systems benefit from the same plain signals: meaningful headings, useful links and content that can be understood without an architectural diagram.
Use siloing to review relationships
Use siloing to ask which pages explain a subject, what a reader should see next, and whether the site makes that relationship obvious.
That is enough structure. Beyond that, extra rules can become ceremony.
The language of SEO silos comes from an older SEO vocabulary. Current search systems still need clear subjects and relationships, but a useful site should let its pages help one another.
Choose one important page, list the three questions a reader is most likely to have next, and check whether the current page links to the best answers. Add only the links that make those relationships clearer.
