How long should a content pillar page be?

Pillar pages are typically 2,000 to 5,000 words because they need to cover a broad topic comprehensively. However, length is a byproduct of thoroughness, not a target. The page should be as long as it needs to be to introduce every major subtopic and link readers to deeper cluster content - no longer.

How many content pillars should a startup have?

Start with 3 to 5 content pillars that map to your core product areas or the main problems your customers face. Each pillar should represent a topic you want to be known for and can create 10 to 20 supporting cluster pages around. Expanding beyond 5 pillars before thoroughly building out your first few dilutes your topical authority signals.

What is the difference between a pillar page and a blog post?

A pillar page covers a broad topic at a high level and links out to cluster pages for deeper dives. A blog post typically focuses on a specific subtopic in depth. Pillar pages are designed to be updated frequently and serve as hubs. Blog posts are more often standalone pieces that link back to the pillar. Think of the pillar as the table of contents and cluster posts as the chapters.

What Is a Content Pillar?

A content pillar is a comprehensive page that covers a broad topic in depth and serves as the central hub for a cluster of related content. The pillar page provides an overview of the entire topic, while individual cluster pages dive deep into specific subtopics - all linking back to the pillar and to each other. This structure helps search engines understand your site's expertise and helps readers navigate from broad concepts to specific details.

How Does the Pillar-Cluster Model Work?

The pillar-cluster model organizes content into a hierarchy:

The pillar page covers a broad topic comprehensively. For example, a pillar page on "social media distribution" would explain what distribution is, why it matters, which platforms work, and what strategies exist - touching on everything without going too deep into any single area.

Cluster pages cover specific subtopics in detail. Supporting the distribution pillar, you might have cluster pages on Reddit marketing, TikTok distribution, LinkedIn strategy, and multi-account management - each going deep on one platform or tactic.

Internal links connect everything. Each cluster page links back to the pillar. The pillar links out to each cluster page. Cluster pages link to each other where relevant. This creates a web of topically related content that search engines can crawl and understand as a cohesive knowledge base.

HubSpot pioneered this model and reported a 25% year-over-year increase in organic traffic after restructuring their blog around pillar-cluster architecture, with improved rankings across more than 2 million keywords.

Why Do Pillar Pages Improve SEO?

Topical Authority Signals

Search engines evaluate whether a site has genuine expertise on a topic. A single blog post about video marketing tells Google you mentioned the topic. A pillar page on video marketing linked to 15 cluster pages covering hooks, formats, platforms, editing tools, and strategy tells Google you are an authority on the subject. This is the foundation of topical authority.

Consolidated Link Equity

When cluster pages earn backlinks, the internal links from those pages pass authority back to the pillar. The pillar then distributes that authority outward to all cluster pages. This creates a rising-tide effect where every new cluster page and every new backlink strengthens the entire topic cluster.

Better Keyword Coverage

A well-built pillar-cluster structure allows you to rank for hundreds of related keywords across the cluster. The pillar page targets broad, high-volume terms while cluster pages target specific, long-tail queries. Together, they capture traffic across the entire search landscape for a topic. Keyword clustering ensures each page targets a distinct intent without competing against other pages in your cluster.

Improved User Experience

Readers who land on a cluster page and want more context can follow internal links to the pillar. Readers who start at the pillar can drill down into whatever subtopic interests them. This navigation pattern keeps people on your site longer and helps them find exactly what they need - both of which send positive engagement signals to search engines.

How Do You Create a Content Pillar?

Step 1: Choose Your Pillar Topics

Pick broad topics that meet three criteria:

Strategic relevance - The topic directly connects to your product, service, or area of expertise
Search demand - People actually search for this topic and its subtopics
Cluster potential - You can identify at least 10 to 15 subtopics worth individual pages

At Conbersa, our pillar topics include social media distribution, AI search optimization, and content strategy - each directly connected to the problems our product solves.

Step 2: Map Your Cluster Pages

For each pillar, brainstorm every subtopic a reader might want to explore. Use keyword research to validate search demand and keyword clustering to group related terms.

A content strategy pillar might include clusters on:

Content velocity - publishing frequency
Content decay - traffic decline over time
Content refresh - updating existing content
Content distribution channels
Content repurposing strategies
Content measurement and analytics

Step 3: Write the Pillar Page

The pillar page should:

Define the broad topic clearly in the opening paragraph
Cover every major subtopic at a summary level (1 to 3 paragraphs each)
Link to cluster pages wherever you reference a subtopic that has its own dedicated page
Be comprehensive but not exhaustive - provide enough context for readers to understand the landscape, then direct them to cluster pages for depth

Step 4: Build and Connect Cluster Content

Write cluster pages and ensure every one links back to the pillar page. Also link cluster pages to each other where the connection is natural. As you publish new cluster content, go back and update the pillar to include links to the new pages.

Step 5: Maintain Over Time

Pillar pages need regular content refreshes. As you add cluster pages, update the pillar to link to them. As subtopics evolve, update the pillar's coverage. According to Ahrefs' research, the average top-ranking page is about 5 years old, but its content has a median age of only 7 to 8 months. Successful pillar pages are living documents that grow and evolve.

Content Pillar Examples for Startups

SaaS product → "Complete Guide to [Problem Your Product Solves]" Cluster pages cover specific aspects of the problem, comparison pages evaluate solutions, and how-to pages walk through implementation.

E-commerce brand → "[Category] Buying Guide" Cluster pages cover individual product types, comparison pages, care guides, and trend roundups.

Service business → "[Service Area] Strategy Guide" Cluster pages cover specific tactics, case studies, tool comparisons, and common mistakes.

The pillar-cluster model is not theoretical. It is the dominant content architecture used by companies that consistently win in organic search. Starting with 3 well-built pillars, each supported by 10 to 15 cluster pages, gives a startup a content foundation that can drive meaningful organic traffic within 6 to 12 months - and continue compounding for years.
