How to Audit Your Content Silos for SEO

TL;DR: Content silos are not an SEO folder trick — the useful version is a maintenance system for topical focus, crawl paths, and internal links. The bad version is a pretty site map that traps pages away from the links they need.

If your silo only exists in a spreadsheet, Google does not care.

Google follows links and reads pages. It does not crawl your color-coded content map, your workshop notes, or the tidy taxonomy your team approved three quarters ago. I have seen this go wrong on client sites through mindnow, on vadimkravcenko.com, and now inside seojuice.com, where internal linking is both the product problem and the editorial problem. The mistake is always the same: people redesign the taxonomy and call the silo done.

“Siloing is not all there is to ranking, but without it the on-page relevancy battle is lost.”

Bruce Clay is right about the relevancy battle. The battle is not won by hiding pages from each other. It is won by making the right pages obviously related.

A content silo is a link pattern, not a folder name

A content silo is a group of pages about one topic, connected in a way that helps users and search engines understand the relationship between the hub, subtopics, and supporting pages. For content silos seo, the useful unit is the crawlable relationship between pages, not the folder.

Four structures get mixed together — and confused for one another:

  • Folder structure is visible in URLs (the visible URL path).
  • Navigation structure is visible in menus, breadcrumbs, category pages, and template links.
  • Internal link structure is what search engines actually crawl from page to page.
  • Editorial structure is what keeps the silo from turning into random content over time.

Those structures can support each other, but they are not interchangeable. A URL like /seo/internal-linking/anchor-text/ looks organized. If no important page links to it, the organization is mostly cosmetic.

Take seojuice.com as the simple example. A page about internal linking for SEO, a page about internal link anchor text, a page about orphan pages, and a page about crawlable links belong near each other. They explain the same operating system. A page about “best CRM software” probably does not belong there, even if someone can force an internal link into a paragraph.

Physical silos and virtual silos both exist. Physical silos use URL paths to group pages (e.g., /seo/internal-linking/). Virtual silos use internal links, navigation, and breadcrumbs even when URLs are flatter. Most modern sites use a mix. That is fine. The rule is simpler than the naming: if users cannot follow the topic through links, the silo is fake.

Why content silos still matter for SEO

Content silos still matter because they help with five things: crawl discovery, relevance, authority flow, user navigation, and editorial focus. None of that requires mystical SEO architecture. It requires crawlable paths and sane publishing rules.

“Every page you care about should have a link from at least one other page on your site.”

That line from Google Search Central is the floor. A silo cannot help a page that no other page links to. If your strongest guide, category, or product page never points to a supporting article, that article is outside the practical silo even if the spreadsheet says otherwise.

The second layer is anchor text. Google’s documentation is direct here too:

“The better your anchor text, the easier it is for people to navigate your site and for Google to understand what the page you're linking to is about.”

“Read more” links can help users when the surrounding context is obvious, but they do not build a clear topic map by themselves. Descriptive anchors do. “Orphan pages,” “crawl depth,” “anchor text for internal links,” and “internal link audit” tell the reader and crawler what comes next.

Content silos also give your stronger pages a job. The hub page should collect demand around the broad topic and send people into the best supporting pages. Child pages should return context to the hub and point to siblings when the next step is obvious. That creates a local network of meaning rather than a pile of loosely related articles.

There is also a topical-drift angle. Mike King’s analysis of the 2024 Google leak is not official Google documentation (not official Google documentation), but it gives a useful model for thinking about topic distance:

“Google is specifically vectorizing pages and sites and comparing the page embeddings to the site embeddings to see how off-topic the page is.”

Even if the exact systems change, the practical lesson holds. If a site builds a tight internal linking silo around internal links, then stuffs in an easy keyword about CRM pricing, the group becomes harder to understand. One stray page will not destroy a site. A habit of stray pages will.

I made this mistake for years (I was wrong about this for years). I treated the content plan as if it were stable after publication. It never is. Every new article, redirect, deleted page, and template change shifts the silo.

The old hard-silo rule is too strict

Classic siloing taught discipline because sites were chaotic. That part still holds. The rigid version can go too far.

“When linking out to other pages in the site, you must be very cautious about risking the integrity of your silo.”

The caution is right — the fear is the problem. Modern sites publish across product pages, education, comparisons, support docs, founder-led essays, glossaries, and templates. Topics overlap. A SaaS page about internal link automation may naturally need to link to a technical SEO guide. An ecommerce guide about running shoe fit may need to link to returns policy content. Blocking those links to “protect the silo” can make the site worse for users.

Link type Usually safe? Why
Hub to direct child page Yes Reinforces the main topic path.
Child page back to hub Yes Consolidates relevance and helps navigation.
Sibling page to sibling page Yes Helps users move between related subtopics.
Silo page to a closely related page in another silo Often Useful when the user would naturally need it.
Silo page to a random commercial page Usually no Blurs intent and looks forced.
Every article linking to every money page No Creates sitewide noise instead of topical clarity.

A soft silo is disciplined, not weak. It allows cross-silo links when they help the user and preserve meaning. It rejects links added only because a page has commercial value.

How to build a content silo that works

Pick the hub page first

The hub is the page that should rank for the broad topic. It can be a guide, category page, service page, glossary index, or product collection. It must be useful on its own, not a doorway page with a list of links.

For SEOJuice, a natural hub might be “Internal Linking for SEO.” Supporting pages could cover anchor text, orphan pages, crawl depth, link equity, topic clusters, and content silos. The hub should explain the whole system and route readers to the deeper pages.

Map supporting pages by search intent

Do not group pages only because keywords look similar. “Internal linking tools” and “internal linking strategy” are related, but the reader is at a different stage. One wants software options. The other wants a process. Both can live in the same neighborhood, but they need different anchors and different next clicks.

This is where many content maps become too neat. A searcher does not care that two keywords share a modifier. They care whether the next page solves the next problem.

Create the minimum link pattern

Every child page links to the hub. The hub links to every important child page. Strong child pages link to closely related siblings where the next click is obvious. That is the minimum pattern.

Keep it blunt. If a page matters, it needs a crawlable link. If it sits in the silo but nothing links to it, it is not in the silo in any meaningful SEO sense.

Write anchors that say what the page is

Use anchors like “orphan pages,” “anchor text for internal links,” and “crawlable links.” Avoid vague anchors when the purpose is topical clarity. You do not need to stuff exact-match anchors into every paragraph. You do need enough descriptive links that the page relationship is obvious.

Anchor text also decays. A link that made sense two years ago may point to a page that has changed intent. A guide may become a product page. A glossary page may become a full tutorial. Review the anchor, not just the URL.

Add breadcrumbs or contextual navigation

Breadcrumbs help users understand where they are. Contextual links help them decide where to go next. A good silo often uses both. On ecommerce sites, breadcrumbs may carry the category relationship. On editorial sites, contextual links often matter more because topics are less rigid.

Template links are useful, but they are blunt. Contextual links inside the body usually explain meaning better because the surrounding paragraph tells the reader why the destination matters.

Prune or move pages that do not belong

Pruning feels harsh — it is usually maintenance. Teams add pages forever and rarely remove anything. Then the silo becomes a storage room.

If a page sits outside the topic, choose one of four actions: move it to a better silo, rewrite it to fit the search role, noindex it if it has no search role, or consolidate it into a stronger page. The worst option is leaving it half-connected because nobody wants to make the call.

Content silo examples

SaaS example

Hub: “Internal Linking Software.” Children: “Anchor Text Suggestions,” “Orphan Page Detection,” “Internal Link Audits,” “Automated Internal Links,” and “Crawl Depth Reports.”

The product page and educational content can support each other. A page explaining orphan page detection can link to the product feature when the user is clearly looking for a way to find those pages. But not every blog post should point to pricing. That pattern teaches the site to shout instead of guide.

Ecommerce example

Hub: “Running Shoes.” Children: “Trail Running Shoes,” “Road Running Shoes,” “Stability Running Shoes,” “Running Shoe Size Guide,” and “How Long Do Running Shoes Last?”

Buying guides and category pages can sit in the same silo when links match user intent. A trail running shoe category can link to a size guide. A durability article can link to replacement recommendations. Faceted navigation needs control here (for ecommerce, this often means filters need rules), or the silo becomes thousands of thin crawl paths.

Editorial example

Hub: “Technical SEO.” Children: “JavaScript SEO,” “Indexing,” “Crawl Budget,” “XML Sitemaps,” and “Canonical Tags.”

“JavaScript is killing the crawling budget.”

That Bartosz Goralewicz quote belongs in a narrow context here — the silo point is that bloated templates, blocked links, and slow rendered navigation can weaken the practical value of a content structure, even when the editorial plan is right.

A technical SEO silo can look perfect on paper and still fail if the links are hidden behind rendered navigation that crawlers do not reliably reach. The editorial plan and the technical implementation have to meet.

How to audit an existing silo

I would audit the link pattern before arguing about URL folders. At mindnow, the folder debate was often a distraction. On vadimkravcenko.com, the bigger gains came from deciding which pages deserved links from stronger pages. With seojuice.com, the product assumption is sharper: a recommendation is only good if it improves a real path, not just a graph metric.

  1. List the hub and all intended supporting pages. Start with the pages the silo is supposed to contain. Do not trust the CMS category as the final source of truth.
  2. Check whether each page has at least one crawlable internal link. If nobody links to it, the page is orphaned or close to orphaned.
  3. Check whether each child page links back to the hub. This return path helps users reset context and helps the hub remain central.
  4. Review anchors for clarity and repetition. Look for vague anchors, overused exact matches, and anchors that no longer describe the destination.
  5. Find orphan pages and near-orphan pages. A page with one buried link from an old tag archive is technically reachable, but weak in practice.
  6. Identify off-topic pages inside the silo. Ask whether the page helps the topical neighborhood or only chases a loose keyword.
  7. Add, remove, or redirect pages based on search role. Do not keep pages only because they exist.

“I may flag technical issues that are actively hurting you, but the focus is strategic, not technical.”

Marie Haynes is talking about site quality audits, but the same principle applies to content silos. Do not stop at broken links. Decide whether each page still belongs, what job it has, and which page should be stronger because of it.

This is where internal linking tools can help, but tools should not make the editorial decision for you. A graph can show missing paths. It cannot always know whether a page is off-topic, outdated, or simply under-supported.

Common content silo mistakes

Mistake 1: Building the silo in a spreadsheet and never linking the pages

The map becomes useful only when it changes the site. Google crawls links. Users click links. A spreadsheet can guide the work, but it cannot substitute for crawlable paths.

Mistake 2: Treating URL depth as the whole architecture

A clean path like /blog/seo/internal-linking/ helps humans understand the page location. It does not rescue an isolated page. A flatter URL with strong internal links can outperform a deeply nested URL with no practical support.

Mistake 3: Blocking useful cross-silo links

If a reader needs the next page, link to it. Link discipline should reduce noise, not create locked rooms. The test is simple: would a serious reader expect this next step? If yes, the link probably belongs.

Mistake 4: Publishing off-topic content because the keyword looks easy

Mike King’s leak analysis also discusses siteFocusScore and siteRadius:

“The siteFocusScore captures how much the site sticks to a single topic. The site radius captures how far the page goes outside of the core topic based on the site2vec vectors generated for the site.”

Again, do not optimize for leaked metric names. That is the wrong lesson. The useful lesson is that topical drift has a cost. If your internal linking silo is about technical SEO, publishing a loosely related “best AI headshot tools” article because the keyword looks easy will make the site harder to understand.

Mistake 5: Forgetting maintenance

A silo changes every time you publish, delete, merge, redirect, or update a page. Treat it like an editorial system (in 2026, this is no longer optional). Review the hub. Review the children. Review the anchors. Then make the next link obvious.

Content silos vs topic clusters vs site architecture

These terms overlap, so teams often rename the same messy system three times. The label matters less than whether pages are discoverable, related, and maintained.

Term What it means What to check
Topic cluster The content strategy model around one broad subject. Do the planned pages cover the searcher’s real questions?
Content silo The linked structure that keeps that topic understandable. Do the hub, child pages, siblings, and anchors form a clear path?
Site architecture The whole system: navigation, URLs, templates, links, breadcrumbs, pagination, and crawl behavior. Can users and crawlers reach important pages without friction?

The cluster is the editorial plan. The silo is the connected room. The architecture is the building. If the plan is good but the room has no doors, the architecture fails the content.

The practical rule for content silos in 2026

A content silo is healthy when the hub is clear, every important page is reachable, child pages point back to the hub, anchors explain the destination, sibling links help real journeys, and off-topic pages are moved or cut.

Do not ask only, “Do we have silos?” Ask, “Can Google and users see which pages belong together?” That question catches the failures a folder audit misses.

For seojuice.com, I care less about drawing perfect silos and more about making the next internal link obvious, crawlable, and useful. That is where the SEO value is. A tighter URL structure can help. A better spreadsheet can help. But the real work happens when the right page links to the right page with words that make the relationship clear.

FAQ

Are content silos still good for SEO?

Yes, when they are built as crawlable link patterns rather than static folder diagrams. They help search engines discover pages, understand topical relationships, and see which pages are central to a topic.

Do I need physical URL silos?

No. Physical URL silos can help organization, but virtual silos can work with flatter URLs if the internal links, navigation, breadcrumbs, and anchors make the topic relationship clear.

Can I link between different silos?

Yes, when the link helps the user and preserves topical clarity. A cross-silo link to a closely related page is often useful. A forced link from every article to every commercial page creates noise.

How many pages should a content silo have?

There is no fixed number. A small silo might have one hub and five strong child pages. A large ecommerce or editorial silo might have hundreds. The better question is whether each page has a search role and a clear internal link path.

How often should I audit content silos?

Audit important silos after major publishing pushes, migrations, redesigns, or pruning projects. For active sites, a quarterly review is a reasonable rhythm. Fast-moving editorial sites may need a monthly check.

Want cleaner internal links?

SEOJuice helps you spot the supporting pages that should sit inside a silo but get one buried link from a stale tag page — and the hubs that have lost their best descendants to anchor-text drift. If your content map looks good but the crawl paths do not, start with the links.
