Content Hub: Types, Pillar Pages and Examples

A content hub is a set of pages about one subject, organized around a central pillar page that introduces the subject and links to a supporting page for each part of it. In SEO terms it is a site structure, not a product: it turns a pile of posts into something both readers and search engines can navigate as a whole.

This guide is for marketers and site owners planning or restructuring content. It covers the three hub types worth knowing, how to build the pillar page, the URL and navigation choices that hold a hub together, three real hubs you can study, and the mistakes that quietly break most hubs.

Content hub vs Content Hub software

“Content hub” means two unrelated things, and the search results mix them. In our live Google check on 22 September 2026, all three top organic results for “content hub” were software: a product called ContentHub, Adobe Experience Manager’s Content Hub feature, and HubSpot’s Content Hub. People Also Ask included “How much does HubSpot Content Hub cost?”

This page is about the other meaning: a hub as a way of organizing pages on your own site. You can build one in WordPress, Webflow, Astro or anything else. No product is required.

The distinction matters because the planning questions are different. Software decisions are about workflow and budget. Hub decisions are about which subject you want to own and how the pages relate to each other.

The three types of content hub

Most hubs fall into one of three shapes: hub and spoke, library, or topic gateway. The right one depends on how people move through the subject.

Hub and spoke. One pillar page, a set of supporting pages, all linked to the pillar and to their closest siblings. This is the classic “pillar and cluster” model. It suits subjects with a clear core and a set of distinct sub-questions, like a service line.

Library. A structured index of many pages grouped into sections, often with short descriptions under each link. It suits broad subjects with lots of reference material, like a glossary, a resource center or an SEO learning hub.

Topic gateway. A top-level page that routes people into several content types on one subject: guides, tools, videos, documentation. It suits organizations that serve different audiences or skill levels on the same subject.

The diagram below compares the three structures.

What makes a good pillar page?

A good pillar page defines the subject, answers each major sub-question in a paragraph, and links to the page that answers it in full. It is a real page with real content, not a table of contents with a hero image.

The pillar has two jobs that pull in different directions. It has to be complete enough to satisfy someone who only reads it, and brief enough that the spokes still have a reason to exist. The fix is a consistent pattern for every section: a direct answer in two to four sentences, one useful specific, and a descriptive link to the spoke.

Its anatomy, top to bottom:

Two details make a difference. First, write the pillar last, or at least revise it last, so it reflects what the spokes actually say. Second, put the definition in the first paragraph and make it quotable: that single passage is what People Also Ask, featured snippets and AI answers are most likely to lift. Our guide to People Also Ask covers answer formatting in detail.

URL structure and navigation for a hub

Give the hub its own folder, put every spoke inside it, and link the hub from your main navigation. That makes the structure visible in three places at once: the URL, the breadcrumb and the menu.

Google’s URL structure guidance asks for simple, readable URLs, words rather than ID numbers, and hyphens rather than underscores. A hub folder does all of that naturally:

• Hub: /seo/
• Spokes: /seo/keyword-research/, /seo/link-building/, /seo/technical-seo/

The folder is a convenience, not a ranking factor. What matters more is linking. Google’s link best practices say that “every page you care about should have a link from at least one other page on your site” and that good anchor text is “descriptive, reasonably concise, and relevant to the page.” In a hub, every spoke should get a link from the pillar and from at least one sibling, with anchor text that names the spoke’s topic. See our guides to internal linking and anchor text.

Breadcrumbs make the hierarchy explicit. Google says a breadcrumb trail “indicates the page’s position in the site hierarchy” in its breadcrumb structured data documentation. Our breadcrumb schema guide covers the markup.

Hub examples worth studying

Three public hubs show the three types well. We describe their structure as it stood when we checked them on 22 September 2026.

What they share matters more than how they differ. Each has one obvious entry page, a URL folder that mirrors the structure, sections named after the questions a reader has, and links in both directions. None of them is organized by publication date.

How do you build a content hub step by step?

Build a hub by choosing one subject, mapping its questions, deciding the type, writing the spokes, then writing the pillar and wiring the links. In order:

1. Choose the subject. Pick one that maps to what you sell and that you can cover credibly. That is how hubs build topical authority rather than just page count.
2. Map the questions. Pull People Also Ask, sales questions and search data. Group them by intent. Each group becomes a spoke.
3. Audit what you already have. Most sites already have half a hub scattered across the blog. Reuse, merge and redirect before writing anything new.
4. Pick the type and URL folder. Hub and spoke for a service line, library for a reference collection, gateway for mixed formats.
5. Write the spokes. Each one answers its question completely, answer first. Our guide to SEO content writing covers the process.
6. Write the pillar. Summarize each spoke in a short section with a descriptive link.
7. Wire the links and navigation. Pillar to spokes, spokes to pillar, spokes to siblings, hub to main menu, breadcrumbs everywhere.
8. Maintain it. Add a spoke when a new question appears. Update the pillar when a spoke changes.

Mistakes that break hubs

Most hubs fail because of structure, not writing. The common failures:

• A pillar that is only links. Readers bounce, and there is no passage worth quoting.
• Spokes that repeat the pillar. If the spoke adds nothing, merge it.
• Two spokes for one intent. They compete with each other. Merge them into one page.
• Orphaned spokes. A page added later that nobody linked from the pillar.
• Hub buried in the blog. If the only way in is paginated archives, the hub barely exists.
• Chasing page count. Thin spokes written to fill a map dilute the whole cluster. They also tend to join the long tail of pages nobody visits: Ahrefs found that 96.55% of pages in its index get zero traffic from Google.

How to tell whether a hub is working

A working hub shows up as breadth: more queries, across more of the subject, landing on more of the hub’s pages. Watching the pillar alone will mislead you, because a good pillar often sends its traffic onward to the spokes.

Measure these in Google Search Console, filtered to the hub’s URL folder, which is one more reason to give the hub its own folder. The Performance report shows the past 3 months by default, which is about the right window for a new hub:

• Queries per page. The number of distinct queries each spoke ranks for. A healthy spoke picks up long-tail variations you never targeted.
• Pages with impressions. What share of the hub’s pages appear in search at all. Spokes with zero impressions after a few months are either unindexed, orphaned, or answering a question nobody asks.
• Clicks to the service page. Hubs exist to support something. Track how many visits move from the hub to the page it supports.
• Cannibalization. Queries where two hub pages trade places. That is usually two spokes answering one intent, and the fix is a merge.
• AI citations. Check whether assistants cite hub pages for the hub’s core questions. Our guide to AI visibility metrics that matter covers how.

Give a new hub a full quarter before judging it, and expect the gains to keep building after that. Ahrefs’ study of how long it takes to rank found that only 1.74% of newly published pages reach the top 10 within 1 year, and that 72.9% of pages in the top 10 are more than 3 years old. Pages need to be crawled, indexed and linked before they can rank, and a hub’s value comes from the pages reinforcing each other, which takes time to show.

One more test is qualitative: ask someone outside the team to find the answer to a specific question starting from your home page. If they cannot reach the right spoke in three clicks, your navigation is hiding the hub.

Making your content hub work for search and AI

A content hub works when every page answers one question well, the pillar is useful on its own, and the links make the structure obvious. That serves readers first, and it gives search engines and AI retrieval systems a coherent set of passages on one subject instead of scattered posts. For why structure at the passage level matters to AI engines, see content chunking for AI.
