Definition
A pillar page is a long, comprehensive page covering a broad topic at high level, surrounded by deeper subtopic ('cluster') pages that link to and from it — together forming a topic cluster Google can recognise as topical authority.
The hub-and-spoke model emerged from HubSpot's 2017 reframing of content strategy: stop chasing individual keywords; build clusters that demonstrate topical authority. The pillar covers the topic broadly (3,000–8,000 words); subtopics drill into specifics (1,000–2,500 words each); all interlink with descriptive anchors.
Done well, a topic cluster ranks for hundreds of queries — the pillar for the broad term, the subtopics for the long-tail variants, and the cross-linking compounds authority across the set. Done poorly, you have a 6,000-word post nobody reads and three orphan articles that don't reinforce it. The structural rigour is what makes the difference.
Origin
Articulated by HubSpot in 2017 ('A New Way to Look at Topic Clusters'), drawing on earlier work in topical SEO and information architecture. Now standard practice in B2B and SaaS content marketing.
How it works
- Pick the topic — broad enough to support 8–15 subtopics.
- Outline the pillar at high level: chapters that map to subtopics.
- Plan the subtopics: each one a query you want to rank for.
- Write the subtopics first, link each to the pillar with descriptive anchor text.
- Write the pillar last, summarising and linking out to each subtopic.
- Audit and refresh quarterly. Topic clusters decay without maintenance.
When to use it
Use when
- When a topic has clear subtopics and you're competing for authority, not just one query.
- In content-led B2B and SaaS marketing.
- When you have the bandwidth to write 8+ supporting pieces. Pillars don't work without spokes.
Skip when
- On topics with no subtopic depth. Some queries are single-page-friendly.
- When you can't sustain the cluster. A pillar without spokes is just a long page.
Key metrics
- Rankings on the pillar's primary query.
- Cumulative rankings across the cluster.
- Internal links pointing into the pillar.
- Topical authority signals (cluster depth, freshness, citations).
Examples
- Our 'Complete Guide to Email Marketing' pillar ranks #2; the 12 subtopics cover the long tail.
- A pillar page without subtopics is just a long article hoping for the best.
- We doubled organic traffic by clustering existing content rather than publishing new posts.
In practice at Makreate
Makreate's SEO content engagements often start with a topic-cluster audit — many clients have written 100+ articles with no clustering, leaving traffic on the floor. A recent client had 48 articles on advertising scattered across paid, social, search, programmatic. We restructured into three clusters (Google Ads, Meta Ads, LinkedIn Ads), wrote a pillar for each, and added 200+ internal links to bind them. Within 5 months, organic traffic on advertising-related queries had tripled — without writing new content, just by clustering what was already there.
SEO →Common mistakes
- Publishing the pillar before the subtopics. Order matters — links flow up to the pillar.
- Pillars too narrow. A pillar should support 8–15 subtopics; if it doesn't, it's not a pillar.
- Ignoring the cluster after publication. Topical authority needs maintenance.
- No internal linking discipline. The cluster works because of the links, not the content alone.
Frequently asked
How long should a pillar page be?
3,000–8,000 words is typical. The length isn't the goal; comprehensive topic coverage is. If 4,000 words covers the topic, don't pad.
How many subtopics?
8–15 is the sweet spot. Below 8 and the cluster doesn't have enough depth to demonstrate authority; above 15 and individual subtopics get diluted.
Should I update old content into a cluster?
Almost always. Restructuring existing content into clusters is higher-ROI than writing new content for most established sites.
