The printable internal linking + silo structure checklist SEOing uses on client audits — covering ecommerce, local service and large multi-service websites.

Silo structure internal linking is the practice of grouping your website's pages by topic and controlling internal links so relevance and authority stay concentrated inside each group. Done right, it is the single highest-leverage change most websites can make — no new content, no new backlinks, just a smarter link architecture that Google understands instantly.

In this guide you'll learn how a silo works, the universal rules that apply to every site, and a tailored blueprint for small blogs, large sites, ecommerce stores, local service businesses and big multi-service companies — the exact frameworks SEOing uses on client audits. You can also download the free PDF checklist here.

What Is Silo Structure in SEO?

A silo is a themed group of pages organized around one hub page. The hub targets the head keyword (e.g. "local SEO services"), and the supporting pages cover every sub-topic around it ("local SEO pricing", "Google Business Profile optimization", "citation building"). Internal links flow primarily inside the group: supporting pages link up to the hub and sideways to siblings — not randomly across the site.

The result: Google sees a dense, self-contained cluster of relevant pages, understands exactly what your site is an authority on, and ranks the whole group instead of judging each page in isolation.

Physical vs Virtual Silos (Which One Fits Your Site?)

Physical Silo (URL Directory)

yourstore.com/mens/shirts/oxford-shirt

URL folders mirror the silo. Best for ecommerce categories and large service sites.

Virtual Silo (Internal Links Only)

Flat URLs, but internal links keep PageRank inside the topic. Best for blogs and news sites.

Hybrid Silo

site.com/services/local-seo + /locations/dubai

Directory structure for money pages, link-based silos for supporting content. What SEOing recommends for most businesses.

The 10 Universal Silo Rules (Any Website, Any Size)

Every silo has ONE hub page (pillar / category / service page) that targets the head keyword.
Hub pages link DOWN to every supporting page inside the silo; supporting pages link UP to the hub.
Supporting pages link SIDEWAYS only to sibling pages inside the same silo (2–4 links each).
Never pass PageRank from one silo's money pages to another silo's money pages.
Every page is reachable within 3 clicks of the homepage.
Use exact-match and partial-match anchor text — never 'click here' or naked URLs.
Breadcrumbs follow the silo hierarchy and use BreadcrumbList schema.
One page targets ONE keyword cluster — no two silo pages compete for the same query.
Orphan pages (0 internal links in) get found in every audit and linked into the right silo.
Add new supporting pages under the existing hub — never create a hub per keyword.

Silo Blueprints by Website Type

Small Website / Blog (10–100 pages)

Home → 1 hub per topic → 8–20 supporting articles per hub

Start with 2–3 topic hubs maximum — depth beats breadth.
Each article links up to its hub and sideways to 2–3 siblings in the same topic.
Keep blogroll-style 'related posts' inside the same silo, not site-wide.

Large Website (1,000+ pages)

Home → Main hubs → Sub-hubs → Detail pages (3–4 tiers)

Break big silos into sub-silos of 30–80 pages so every sub-hub stays relevant.
Cap links per page at ~100; paginated listings must link to real pages, not endless pagination.
Automate 'related content' inside the silo — manual interlinking fails at this scale.
Audit quarterly with Screaming Frog: fix orphans, redirect chains and depth > 4 clicks.

Ecommerce Store

Home → Category → Sub-category → Product (+ blog silo)

Category pages are hubs — link each to its best-selling and newest products manually.
Products link UP to their category and breadcrumbs only — not to random related products across silos.
Handle filters (color, size, price) with canonicals or noindex — faceted URLs destroy silos.
Run a separate blog silo that links INTO category pages with content anchors.
Add 'shop the collection' blocks linking sibling categories only when they share intent.

Local Service Website

Home → Service silo → Service×Location pages (+ blog silo)

One silo per core service (e.g. /services/ac-repair/) with 4–8 supporting guides.
Location silo: /locations/dubai/, /locations/abu-dhabi/ … each linked from the footer AND from service pages.
Service + location pages live inside the service silo and link up to both the service hub and the location hub.
Never exceed services × locations you can genuinely write unique content for — 3 unique services × 7 cities beats 40 thin pages.

Large / Multi-Service Company

Home → Service silos × Industry silos × Location silos (matrix)

Three silo dimensions: what you do (services), who you serve (industries), where (locations).
Pick ONE primary dimension for the URL structure; combine the others in page content and internal links.
Industry guides link into every relevant service page; service pages link back to 2–3 industry guides.
Keep a single blog/news silo feeding into all service silos with content-anchored links.
Deduplicate: one page per service-location-industry combination, no thin variants.

Example: Ecommerce Silo in Practice

HOME (passes authority to hubs only)
 │
 ├── SWIMWEAR (category hub)
 │    ├── Men's Swimwear (sub-hub)
 │    │     ├── Swimming costumes → link UP to Men's, SIDE to caps
 │    │     ├── Swim shorts      → link UP, SIDE to costumes
 │    │     └── Rash guards      → link UP, SIDE within sub-hub
 │    └── Accessories (sub-hub)
 │          ├── Swim caps       → link UP to Accessories
 │          └── Goggles         → link UP, SIDE to caps
 │
 └── BLOG SILO (virtual silo)
      ├── "Best swim caps {YEAR_STRING}"  → links INTO Accessories hub
      └── "Swimwear size guide"           → links INTO category hub

How to Implement a Silo Structure in 6 Steps

1. Crawl & Map Your Current Structure

Run a Screaming Frog or Sitebulb crawl. Export every URL with its internal inlinks, outlinks and click depth. Flag orphans, pages deeper than 4 clicks, and pages with generic anchors.

2. Define Your Topic & Money Silos

Group your URLs into silos around your money pages — categories, services, or topic hubs. Each silo gets one hub, 8–80 supporting pages, and a documented keyword cluster so no two pages compete.

3. Fix the Hierarchy (URLs & Navigation)

For ecommerce and large service sites, align URL directories with the silo (/services/local-seo/). For blogs, keep flat URLs and build the silo purely with links. Update breadcrumbs and navigation to match.

4. Rebuild Internal Links

Hub → every supporting page. Supporting page → hub with a content-anchored link. Siblings → 2–4 in-silo links. Remove cross-silo money-page links and generic anchors. Aim for 20–60 contextual links on hubs.

5. Handle Filters, Tags & Duplicates

Canonicalize faceted URLs, noindex thin tag archives, and merge near-duplicate location or variant pages. Every silo page must have unique title, H1 and at least 300 unique words.

6. Audit Monthly & Track Rankings

Re-crawl monthly, fix new orphans within the week, and track cluster-level rankings (not single keywords) in Search Console. Silo wins show up as impressions growth across the whole topic.

Silo Mistakes That Kill Rankings (And What to Do Instead)

Common Mistake	Do This Instead
Footer/site-wide links to every category	Site-wide links to hubs only; deep pages get in-silo contextual links
Related posts widgets pulling from all topics	Related content scoped to the same silo
Every blog post linking to the contact page	Blog posts link up to the service/category hub; the hub converts
Faceted filter URLs competing with category pages	Canonical filters to the clean category URL
New keyword = new hub page	New keyword = new supporting page under the existing hub
Anchor text: 'click here', 'read more'	Descriptive partial-match anchors: 'local SEO pricing guide'
Location pages duplicated from one template with city swapped	Unique local content per location page or don't publish it

Frequently Asked Questions

What is a silo structure in SEO?

A silo structure is a way of organizing a website so that pages about the same topic are grouped together and only interlinked with each other and their hub page. Internal links keep PageRank and topical relevance concentrated inside each topic group, which helps Google understand and rank the whole group for related keywords.

What is the difference between a physical silo and a virtual silo?

A physical silo uses URL directories to group pages (example.com/mens/shirts/), while a virtual silo keeps flat URLs and uses internal links alone to group pages. Physical silos suit ecommerce and large service sites; virtual silos suit blogs. Most businesses do best with a hybrid.

How many silos should a website have?

Small sites should start with 2–3 silos and expand only after each one is fully covered with 8–20 supporting pages. Large sites commonly run 5–15 silos. The rule: never start a new silo until the existing ones are complete and ranking.

How many internal links should each page have?

Aim for 3–10 contextual internal links per supporting page (up to its hub, plus 2–4 siblings), and 20–60 contextual links on hub pages. Keep total links on any page under about 100, and never count navigation or footer links toward silo relevance.

Does silo structure still work for SEO in 2026?

Yes — siloing is more important than ever. Google evaluates topical coverage and entity relationships, and a clean silo structure is the clearest signal of how your pages relate. It also improves crawl efficiency, which matters for AI crawlers and LLM citation systems.

Should I use silo structure on an ecommerce store?

Absolutely. Ecommerce silos map naturally to category → sub-category → product. Category pages act as hubs, products link only up to their category, faceted filter URLs get canonicalized, and a separate blog silo feeds links into the category pages with content anchors.

Can I link between different silos?

Yes, but carefully. Contextual links between related silos are fine and natural — what you must avoid is linking money pages of one silo to money pages of another, or letting related-posts widgets scatter links across unrelated topics. Keep cross-silo links contextual and few.

How long does it take to see results from restructuring internal links?

Most sites see movement within 2–6 weeks of a serious internal link restructure — recrawling and re-evaluation are fast. Full silo benefits compound over 3–6 months as new supporting pages join the structure.

Do silos help rank in AI chatbots like ChatGPT and Perplexity?

Yes. LLM systems and answer engines follow links and chunk pages by topical grouping. A tightly siloed site makes it easy for AI crawlers to understand what each section of your site is an authority on, increasing the chance of citation in AI answers.

How do I fix orphan pages in a silo structure?

Run a crawl (Screaming Frog, Sitebulb or Ahrefs site audit), export URLs with zero internal inlinks, then decide each orphan's silo and add at least one content-anchored link from the hub and one from a sibling page. Re-crawl to confirm zero orphans remain.
