What is a Pillar Page? (And How to Build One That Ranks)

A pillar page is the longest, most comprehensive page in a content silo. It covers the broad topic at an overview level. The supporting pages around it each cover one specific aspect in depth. That relationship, pillar to supporter, is what separates a content silo from a loose collection of blog posts.

If you want to understand how silos work before diving into the pillar specifically, read the complete guide to content silos first. This post focuses on the pillar page itself: what it is, what it looks like in practice, and the mistakes that undermine it.

How a Pillar Page Differs From a Normal Blog Post

Most blog posts go deep on one angle. A post titled “How to find long-tail keywords using Google Search Console” covers that one task thoroughly. That is exactly what a supporter page does inside a silo.

A pillar page does something different. It covers the parent topic across multiple angles, but at overview depth. A pillar page on “keyword research” would touch on keyword types, search intent, tools, difficulty scoring, and how to prioritise. It would not exhaust any single one of those angles. Each angle gets its own supporter page, and the pillar links out to all of them.

Three practical differences from a blog post: a pillar page is longer (typically 1,500 to 3,000 words for most business niches), it links out to multiple supporter pages as part of its structure, and it is written to serve as a navigational hub, not a standalone read.

What a Pillar Page Actually Looks Like

Concretely: a pillar page on “content marketing for accountants” might open with a definition, then move through sections on blogging, social content, email, SEO content, and measuring ROI. Each section gives enough context to be useful on its own, then links to the supporter page that covers that subtopic properly.

The structure follows a predictable pattern. An opening that frames the broad topic. H2 sections, one per major subtopic in the silo. A paragraph or two per section. An internal link to the relevant supporter page. A CTA near the end. No padding.

The internal linking is not decorative. It is functional. Google follows those links to understand the relationship between the pillar and its supporters. How you structure those links matters, which is covered in detail in this post on how to interlink a content silo.

How Many Words Does a Pillar Page Need?

The honest answer: enough to cover the topic comprehensively at an overview level. For most business niches, that lands between 1,500 and 3,000 words. If your topic genuinely has eight subtopics worth exploring, and you spend 200 to 300 words framing each one, you will hit that range naturally.

Do not pad to hit a word count. Do not trim to stay under one. Write until the topic is covered at the right depth, then stop. A 1,600-word pillar that is dense and well-structured will outperform a 3,500-word pillar stuffed with filler every time.

Common Mistakes That Undermine a Pillar Page

The most common mistake is writing a very long blog post and calling it a pillar page. Length alone does not make a pillar. If the page goes deep on one angle instead of covering multiple subtopics at overview depth, it is a blog post. That is not a bad thing, but it will not function as a pillar in a silo structure.

The second mistake is making the pillar so exhaustive that it eliminates the need for supporter pages. If a visitor can get everything they need from the pillar, they have no reason to click through to the supporters. That collapses the silo structure. The pillar should leave the reader wanting more detail on each subtopic, and the supporters deliver that detail.

A third mistake is building the pillar first without planning the silo. If you have not mapped out which supporter pages will accompany the pillar, you cannot write it correctly. Read how to plan a content silo before you write a single word of the pillar itself.

Could Your Existing Content Become a Pillar Page?

Sometimes. Look through your existing posts for content that covers multiple subtopics shallowly. A post that touches on keyword research, on-page optimisation, link building, and technical SEO in a single piece is a candidate. It is already trying to be a pillar; it just lacks the surrounding silo structure and the internal links to make it function as one.

The upgrade process is straightforward. Restructure the existing post into clear H2 sections. Write the supporter pages that go deep on each subtopic. Add internal links from the pillar to each supporter, and from each supporter back to the pillar. That is a silo. For a step-by-step view of SEO content structure more broadly, the complete guide to SEO content writing covers the full picture.

If your existing post is thin on every subtopic, it may need a full rewrite rather than a restructure. Honest assessment first, rewrite second.

Build Your Pillar Page With a Content Silo Package

A pillar page without its supporter pages is just a long blog post. The structure only works as a complete silo. The Classic Sandwich includes one full content silo, pillar page plus supporting pages, written to rank and structured to link correctly from day one. If your site needs topical authority in a specific area, that is where to start.
