A pillar page (roughly ‘pillar page’ in German) is the central, comprehensive content page of a topic cluster. It covers a broad, overarching topic and serves as a hub around which several specialised cluster articles (spokes) are arranged. The pillar page links to each of these spokes, and each spoke links back to the pillar. It is therefore both the content and the table of contents for the entire cluster – and the page intended to rank for the highly competitive head keyword within a subject area.
Pillar pages are a core component of modern content strategies, particularly in the B2B sector. They were popularised alongside the topic cluster model by HubSpot and are the response to search engines evaluating subject matter expertise at domain level rather than individual keywords on individual pages. A well-structured pillar page consolidates the authority of an entire cluster and makes it visible to search engines and readers.
Characteristics of a pillar page
A pillar page differs significantly from a standard blog article. It is more comprehensive, broader in scope and structurally designed to facilitate internal linking. Typical characteristics:
- Breadth rather than depth: It covers the entire main topic without going into every sub-aspect in minute detail – that’s what the spoke pages are for.
- Length: A typical length is 2,500 to 4,000 words, depending on the topic and competition. It must cover enough ground to serve as a comprehensive go-to resource.
- Structure as a table of contents: Each main section corresponds to a sub-topic, outlines it, provides the key answer and links to the relevant spoke for further detail.
- Longevity: A pillar page is designed to be ‘evergreen’ and is updated regularly, rather than becoming outdated like a daily news article.
- Clear URL hierarchy: It is located at a stable, descriptive URL to which all spokes link.
Pillar page, spoke and cluster: the distinctions
These three terms are often confused. The pillar page is the central page for the main topic. The spoke (also known as a cluster article) is a single post on exactly one subtopic, which delves into the subject in depth where the pillar page only touches on it (typically 800–1,500 words). Finally, the cluster is the combination of the pillar and all associated spokes – in other words, the entire ‘wheel’ comprising the hub and spokes. Anyone who confuses pillars and spokes will either end up with a pillar that doesn’t rank for anything, or a collection of spokes without a common umbrella.
Pillar Page vs. Landing Page
A pillar page is not a traditional conversion landing page. A landing page is optimised for a single action (purchase, enquiry, download) and is usually short. A pillar page is information-oriented, broad in scope and designed for organic visibility and internal linking. The two can work together: a pillar page builds trust and reach, and directs readers to landing pages or service pages at appropriate points.
How to structure a pillar page
The structure of a pillar page follows the logic of the cluster it serves. First comes the topic map: the main topic in the centre, surrounded by the subtopics along with the actual search queries they address. This map determines the structure of the pillar page – each main section corresponds to a subtopic. The section provides the core answer and links to the relevant spoke for more in-depth information.
The order of the links is important: the pillar links to every spoke as soon as it exists, and every new spoke is immediately integrated into the pillar upon publication. This ensures the cluster remains cohesive and grows in a controlled manner. Anchor texts should be descriptive and varied, rather than repeating the same keyword twenty times.
Practical example
An e-commerce service provider aiming to rank for “Shopware migration” creates the pillar page “Shopware migration: the complete guide from SW5 to SW6”. It outlines the reasons, phases, risks, effort involved and results of a migration. In each section, it links to the relevant spoke: the section on product data links to the spoke ‘Migrating product data’, the section on costs to the spoke ‘How much does a Shopware migration cost?’, and so on. A reader who only reads the pillar page gets the full picture; anyone with a specific question can click through to the relevant spoke.
Pillar page vs. standard blog article
The difference between a pillar page and a standard blog article is not just a question of length, but of function. A blog article typically answers a specific question and stands on its own. A pillar page, on the other hand, serves as the structural framework for an entire subject area. The key differences:
- Scope and breadth: The blog article is focused (often 800–1,500 words), whilst the pillar page is broad in scope (2,500–4,000 words).
- Role within the cluster: The blog post is usually a ‘spoke’; the pillar is the ‘hub’ to which the spokes link.
- Lifespan: The blog post may be updated daily; the pillar is evergreen and is maintained rather than replaced.
- Linking role: The blog post links upwards to the pillar; the pillar links downwards to all the spokes.
In practice, the two cannot always be strictly distinguished: a particularly comprehensive blog article can be expanded into a pillar, and a pillar itself contains enough substance to rank independently. The decisive factor is its role within the overall structure of the cluster.
URL structure and maintenance
A pillar page should have a stable, descriptive URL that clearly identifies the topic, as all spokes link to it permanently. If the URL changes later, either all internal links must be updated or clean redirects set up – both of which are avoidable efforts with good planning. Maintenance involves linking each new spoke to the pillar immediately upon publication and checking the pillar for up-to-date information at least once a year. Particularly in technical B2B topics, where versions, prices and best practices change rapidly, it is this continuous maintenance that keeps the pillar page alive as a reliable point of reference.
Common mistakes with pillar pages
- The ‘thin’ pillar: A perfect heading structure, but only two sentences under each heading. Readers and search engines immediately recognise such a skeleton lacking substance.
- Missing links: A pillar that does not link to its spokes (or vice versa) is not a true pillar, but rather a long standalone article.
- Topic overload: A pillar that mixes two or three main topics sends a muddled signal. One cluster, one main topic, one pillar.
- No updates: A pillar page that is created once and then forgotten loses authority with every outdated detail.
Types of pillar pages
Not every pillar page looks the same. In practice, several types have emerged, differing in purpose and structure:
- Guide pillar (topic pillar): The most common type. A comprehensive, didactically structured guide to an overarching topic, which explains the subject from the ground up and refers readers to more in-depth ‘spokes’. Example: ‘The Complete Guide to Shopware Migration’.
- Resource Pillar (Resource Hub): A curated collection page that provides structured links to further content – designed more as a directory than as a continuous reading flow. Suitable for very broad subject areas with many sub-resources.
- Product or Solution Pillar: A pillar that comprehensively covers a product, service or solution area and has a stronger commercial focus, without sacrificing the breadth of information.
- ‘10x’ pillar: A deliberately outstanding, particularly in-depth pillar that aims to be the best available document on its topic, in order to stand out from superficial competition.
Which type is suitable depends on the topic and the funnel objective. Informative topics (mid-funnel) usually benefit from a guide pillar, whilst very broad fields of knowledge benefit from a resource pillar.
Pillar pages and internal linking in detail
Internal linking is the mechanism that distinguishes a pillar page from a long single article. Three rules are crucial here. Firstly: no orphans – every spoke must have at least one inbound link from the pillar and one outbound link back to it. Secondly: descriptive anchor text that names the destination, not the click (“How to transfer your product data during migration” rather than “find out more”). Thirdly: contextual placement – a link belongs in the body text where the linked topic is mentioned, not in an appended list of links at the bottom of the page.
For search engines, this interlinking makes the thematic relationship explicit and directs link equity specifically to the pillar, which thereby builds authority for the highly competitive top-level keyword. For human readers, it creates a path through the topic: from the overview in the pillar to the detailed question in the spoke, and on to the logically next question in the neighbouring spoke.
Measuring a pillar page
The success of a pillar page can be assessed using several metrics: the rankings for the head keyword and related terms, the organic traffic to the pillar page itself, the number of incoming internal links from the spoke pages, and the click paths from the pillar page to the spoke pages and vice versa. Google Search Console also shows which search queries the pillar page receives impressions for without ranking well – an indication of missing or underperforming spokes. In this way, the pillar page becomes a control mechanism for the further expansion of the cluster.
Frequently asked questions about pillar pages
How long should a pillar page be?
There is no set standard. A rough guide is 2,500 to 4,000 words, depending on the topic and competition. What matters is not the exact word count, but whether the page covers the main topic comprehensively and credibly.
Can an existing blog article become a pillar page?
Yes. Often, a broad overview article already exists that can be expanded into a pillar: it is expanded upon, structured and linked to the appropriate spokes. Conversely, existing detailed articles can become spokes for this pillar.
How many spokes does a pillar page need?
For a medium-sized cluster, eight to fifteen spokes is a healthy range. Every distinct search intent relating to the main topic deserves its own spoke, to which the pillar page links.
Does a pillar page also help with AI visibility?
Yes. A pillar page that functions as the hub of a closed cluster signals to AI systems a coherent thematic expertise (entity authority) – a prerequisite for being cited in answers from Google AI Overviews and similar systems.
Where should a pillar page be positioned in the funnel?
Pillar pages are particularly effective in the middle of the funnel (the middle of the decision-making process) because they cover a topic in an informative and comprehensive manner and build trust. From there, contextual links lead to in-depth ‘spokes’ and, where appropriate, to commercial service pages or landing pages. A pillar page does not replace these conversion pages; rather, it feeds them with qualified traffic.
A detailed explanation of the concept within the context of content strategy is provided by the HubSpot documentation on pillar pages.
