The degree to which your site covers a subject with depth and clarity. Practically, it looks like well structured hubs, coherent spokes, and links that help readers navigate the topic without guessing.

A set of related pages aligned to one theme. A cluster usually includes a hub, definitions, how to guides, comparisons, use cases, and a solution or pricing destination.

A crawlable anchor that connects pages on your site. The words you choose in that anchor tell both readers and systems what to expect.

Links and anchors

Links convey relationships. Systems rely on crawlable anchors to discover and understand pages. Avoid click handlers without URLs. See Google’s note on crawlable links.

Structure and hierarchy

Short, predictable paths help. The SEO Starter Guide shows examples of clean hierarchies and breadcrumb use. Review the site hierarchy section in Google’s SEO Starter Guide.

Experience signals

Fast, stable pages tend to perform better. Keep an eye on Core Web Vitals targets at web.dev and design clusters that remain performant as you add links and media.

Example layout

• Hub: comprehensive guide that defines the topic and links out.
• Definitions: short pages that answer what and why.
• How to: step based guides with a small table and a checklist.
• Comparisons: head to head and alternatives pages.
• Use cases: role or industry focused pages.
• Solution: product or service page with one primary CTA.

Internal link blueprint

• Spokes link to the hub at top and bottom.
• Each spoke links to two siblings that a reader would need next.
• Every spoke has one BOFU destination with a clear CTA.

The opening

• One sentence definition plus an answer block.
• Three bullets that summarize the steps or subtopics.
• A compact FAQ to mirror common questions.

Link layout

• Use descriptive anchors that match spoke H2s.
• Group links by intent: learn, compare, implement.
• Add a small visual index if the cluster is large.

Proof and CTA

• Short proof block with one case study or metric.
• One primary next step for evaluators.
• Secondary path to a template or checklist.

Good anchor patterns

• onboarding checklist instead of this post.
• compare analytics tools instead of click here.
• migration guide from tool A instead of learn more.

Implementation tips

• Use real anchors with href. Avoid JS only links. See Google’s note on crawlable links.
• Place links where readers decide, not just at the end.
• Limit repetitive anchors in the same paragraph.

URL design

• Keep slugs short and descriptive. Avoid date folders.
• Use one home per concept. Consolidate near duplicates.
• Prefer lowercase and hyphens. Do not encode intent into parameters if a static path fits.

Breadcrumbs

Breadcrumbs help users and systems understand hierarchy. Mark them up with structured data. See Google’s Breadcrumb guide.

<script type="application/ld+json">
{
  "@context":"https://schema.org",
  "@type":"BreadcrumbList",
  "itemListElement":[
    {"@type":"ListItem","position":1,"name":"Analytics","item":"https://example.com/analytics/"},
    {"@type":"ListItem","position":2,"name":"What is product analytics","item":"https://example.com/analytics/what-is-product-analytics/"}
  ]
}
</script>

Navigation

• Global nav stays shallow. Do not list every spoke.
• Use hub landing pages to organize deeper exploration.
• Cross link related hubs with small, descriptive menus.

Duplicates and variants

• Pick a canonical URL for each concept. Use <link rel=”canonical”> for minor variants. Review Google’s canonicalization notes in the duplicate URL guidance.
• Merge near duplicates. 301 the weaker URL and repoint internal links.
• Keep parameters for tracking out of indexable URLs.

Pagination and indexes

• Use logical, crawlable pagination for long indexes.
• Ensure each page is useful on its own. Add contextual links.
• Link the index to key spokes and the hub with descriptive anchors.

Article

Use on guides, hubs, and most educational pages. Keep markup aligned with visible content and follow Google’s structured data policies.

FAQ and HowTo

FAQ for compact questions and answers. HowTo for clear steps with required elements. See the docs for FAQPage and HowTo.

BreadcrumbList

Use across clusters to reflect hierarchy and improve clarity. Validate with the Rich Results Test.

Coverage

• Queries per page for the cluster in the Search Console Performance report.
• Index status and enhancement eligibility in Page indexing.
• Ratio of orphan pages to total pages. Reduce orphans by linking from hubs and siblings.

Movement

• Average position and CTR for hub and top spokes.
• Clicks from hub to spoke and spoke to solution in GA4. See GA4 help on events.
• Scroll depth to the link index and FAQ interactions.

Outcome

• Assisted conversions for the cluster using GA4 attribution.
• Opportunities that touched a hub or spoke inside your lookback window.
• Time to publish and refresh cadence for cluster pages.

Days 1 to 30

• Pick one theme. Define a hub and five to seven spokes.
• Draft the hub outline and link index. Confirm anchors.
• Publish the hub and two spokes with Article and Breadcrumb schema. Validate in the Rich Results Test.

Days 31 to 60

• Publish two more spokes and one comparison page.
• Add compact FAQs and small tables to each page.
• Instrument GA4 events for hub to spoke and spoke to solution clicks.

Days 61 to 90

• Publish the solution page for the theme with one primary CTA.
• Review queries per page, CTR, and assisted conversions. Prune or consolidate weak pages.
• Document anchors, schema, and refresh dates for the cluster.

How many spokes per hub

Five to nine is a practical range. Enough to show depth without overwhelming readers. Expand only after the first set moves the metrics you care about.

Do we need structured data on every spoke

Use Article on most educational pages. Add FAQ where you include clear question and answer blocks. Use BreadcrumbList across the cluster. Keep markup aligned with visible content and validate regularly.

What if two topics overlap

Pick a primary home and differentiate the angle in the opening paragraph. If confusion persists, merge pages and redirect the weaker URL.

Are external links risky

No. Linking to reputable sources improves clarity and trust. Qualify paid or promotional links with the right attributes per Google’s guidance.
