A pillar page is the longest, most comprehensive piece of content on a given topic on your website. It covers a subject broadly and links out to more detailed posts on specific subtopics. If you have been publishing blog posts without a clear structure, a pillar page is what ties them together and gives Google a clear signal about what your site is authoritative on.
Most sites produce content without thinking about how each post relates to the others. Pillar pages fix that. They sit at the top of a topic cluster — one broad post supported by a cluster of more specific articles, all interconnected. The result is a stronger site structure, better internal linking, and posts that reinforce each other rather than competing. If you are building out your internal linking strategy or already working on topic clusters, writing pillar pages is the natural next step.
What a Pillar Page Actually Is
A pillar page covers everything a reader needs to know about a broad topic without going deep on any one aspect. Think of it as an overview with depth — it gives the full picture, explains the components, and points to more detailed posts for each. A pillar page on website performance, for example, would cover caching, image optimisation, hosting, Core Web Vitals, and more, with internal links to dedicated posts on each subtopic.
The length is typically 2,000–4,000 words depending on how broad the topic is. It is not just a long blog post — the structure, headings, and internal linking pattern are distinct. Pillar pages are often updated more frequently than other posts because they reflect the current state of a topic.
How to Choose the Right Topic for a Pillar Page
A pillar page topic must be broad enough to support multiple subtopic posts, but specific enough to attract a defined search audience. “Website” is too broad. “Website security” is right. A good pillar topic is something you can write five to ten cluster posts about — each one covering a specific aspect in detail.
Start with keyword research to confirm there is search demand for the topic and its subtopics. You want a primary keyword with meaningful monthly search volume — something between 1,000 and 10,000 searches per month is typical for a pillar topic on a newer site. Avoid topics where a single giant site (Wikipedia, a major platform’s documentation) dominates every search result — these are hard to rank against even with strong content. Google’s own guidance on creating helpful, reliable, people-first content is worth reading before you start, since it explains what actually earns a page authority in the first place.
Once you have the topic, map out the subtopics. These become your cluster posts. If you already have posts on those subtopics, your pillar page can link to them immediately. If not, the pillar page is the roadmap for what to write next.
How to Structure a Pillar Page
Opening and scope
Open with a practical paragraph that defines the topic and why it matters. Set the scope clearly — this page covers X broadly; detailed guides on specific aspects are linked throughout. Readers arriving from search need to know within the first two paragraphs that they are in the right place.
Main sections with H2 headings
Each H2 section covers one component of the broader topic. A pillar page on “website SEO” might have sections on technical SEO, on-page SEO, keyword research, internal linking, and site speed. Each section gives enough information to be genuinely useful, then links to a more detailed post if one exists.
Use H3 subheadings within sections where a subtopic has multiple parts. Keep the heading hierarchy consistent throughout — H2 for major sections, H3 for sub-points within those sections, no H4 or deeper.
Internal links within content
Internal links are what make a pillar page structurally different from a long blog post. Each main section should link to one or two cluster posts on that subtopic. The anchor text should be descriptive — not “click here” or “read more”, but the actual subject of the linked post. If your pillar page links to eight cluster posts, those eight posts should also link back to the pillar page, reinforcing the cluster structure. The cornerstone content approach follows this same principle — a central piece that anchors a network of supporting articles.
How to Publish a Pillar Page
Most platforms distinguish between two content types: a chronological, categorized entry — a “post” — and a static, standalone page. A pillar page belongs with your regular content, not as a standalone page, so it can carry categories and tags and surface in your normal content feed alongside its cluster posts. On WordPress specifically, that means creating it as a Post rather than a Page — the standard block editor, using its paragraph, heading, and list blocks, is enough; no page builder is needed.
Set a descriptive SEO title and meta description focused on the primary keyword. Studying how the step-by-step guide to making a website links its own broad sections to more detailed posts is a good model for how a pillar page’s internal links should work — broad section, specific link, repeated throughout.
Add an anchor ID to each H2 heading so you can link directly to a section from other posts or from a table of contents. Most block-based editors expose this as an “anchor” or “HTML ID” field somewhere in the heading block’s own settings — on WordPress, it sits under the heading block’s advanced settings panel as “HTML anchor”. A table of contents plugin or add-on will often generate these automatically once they are set.
How to Update and Maintain a Pillar Page
Pillar pages need more regular updates than standard blog posts. Every time you publish a new cluster post that belongs to this topic, come back to the pillar page and add a link to it. If any of the information in a section becomes outdated — a tool you rely on changes its interface, a Google update shifts best practices — update that section promptly. A stale pillar page signals to both readers and search engines that the content is not being maintained.
At minimum, review your pillar pages every six months. Check that all internal links resolve, that linked cluster posts still exist, and that the content still accurately reflects how things work. Add any new cluster posts published since the last review.
Common Mistakes When Writing Pillar Pages
- Too narrow a topic: If you cannot think of at least five distinct subtopic posts, the topic is too specific for a pillar page — write a single in-depth post instead.
- Too broad a topic: A pillar page on “SEO” covering everything from technical audits to link building in one post is unmanageable and unfocused. Pick a specific angle within the broader subject.
- No cluster posts yet: Publishing a pillar page with no cluster content to link to weakens the whole point of the structure. Write at least three cluster posts before or alongside the pillar page.
- Treating it as a one-time piece: Pillar pages need ongoing maintenance. Adding new cluster posts without updating the pillar page breaks the cluster structure over time.
- Forgetting to link back from cluster posts: Every cluster post should include a contextual link back to the pillar page. This bidirectional linking is what tells search engines the content is part of a coherent topic cluster.
Conclusion
A pillar page is not the longest post you will ever write — it is the most strategically important one within a topic. Choose your topic carefully, map out the cluster posts, and keep the pillar page updated as the cluster grows. The structure pays off in cleaner site architecture and stronger search visibility across all related posts.
