With roughly 94% of all clicks going to organic search results, ranking higher on Google is crucial. Content pillars and topic clusters can help you achieve that by structuring your website’s content effectively. This approach groups your pages by topic so each piece supports the others, boosting your site’s authority and making it easier for visitors to find what they need.

Search engines have become much smarter over the years, and they now reward websites that demonstrate depth and organization in their content. Gone are the days of simply publishing dozens of standalone blog posts each targeting a single keyword. Today, Google’s algorithms evaluate context and topical authority – they look for sites that thoroughly cover a subject and answer the many questions users have about that topic. Using a pillar-and-cluster content model addresses these changes by creating a clear structure that both search engines and readers can navigate easily. It’s a strategic shift from a scattershot approach to a focused, topic-based content strategy that aligns with how modern SEO works.

What Are Content Pillars?

Content pillars are the foundation of your content strategy. A content pillar (or pillar page) is a comprehensive, in-depth page that covers a broad topic essential to your business. Think of it as an ultimate guide that provides a full overview of a subject in one place. Pillar pages are typically longer than standard blog posts and serve as authoritative resources for readers. Because they’re so detailed and valuable, pillar pages often attract backlinks and become key pages for organic traffic.

Key qualities of an effective pillar page:

  • Comprehensive coverage: It addresses all major aspects of the broad topic, providing meaningful insight and answers in one place.
  • Evergreen value: The content remains relevant over time (with updates as needed), so readers and search engines see it as a lasting resource.
  • Internal linking hub: The pillar page links out to related, in-depth articles (cluster pages) and may also link to helpful external sources, reinforcing its role as an information hub.

“Choosing the right content pillar sets the stage for all your other content. It’s how we ensure our site covers a core topic thoroughly and signals our expertise to search engines,” explains the Strategy Team at Emulent Marketing.

What Are Topic Clusters?

Topic clusters are a collection of interrelated content pieces that all tie back to a central content pillar. If the pillar page is the hub, the cluster pages are the spokes. Each cluster post delves into a specific subtopic or common question under the broader theme of the pillar. By linking all these cluster posts to the pillar page (and usually linking them to each other where relevant), you create a tightly knit content group. This structure signals to search engines that your website has breadth and depth on the topic. For users, topic clusters make it easy to explore a subject; someone who lands on one blog post can discover a dozen related posts through your internal links, keeping them engaged on your site.

:contentReference[oaicite:0]{index=0} For example, imagine a travel website creates a pillar page about “U.S. National Parks Trip Planning.” That page offers a broad guide to planning a national parks trip. Supporting it are cluster articles on specific subtopics such as “Best Times to Visit U.S. National Parks” and “Packing Checklist for a National Park Adventure.” Each of those cluster pages dives deep into its particular niche and all of them link back to the main pillar page, which in turn links out to each subtopic. This hub-and-spoke model ensures that anyone interested in national park travel can easily navigate between general guidance and detailed insights on each aspect of the trip.

Why topic clusters boost SEO and UX:

  • Topical authority: Covering a range of subtopics shows Google that you’re an authority on the overall subject, which can boost your rankings.
  • Better user engagement: Visitors can find what they need through your linked pages, keeping them on your site longer instead of bouncing away.
  • Improved crawlability: A clear linking structure helps search engines discover and index all your related content. When one page does well, it can lift the others too.

“When each blog post is part of a topic cluster, we stop creating content in a vacuum and start building a connected ecosystem of knowledge,” notes Emulent Marketing’s Strategy Team.

Selecting the Right Content Pillars

Choosing your content pillars is a crucial first step – these are the broad themes that will define your site’s authority. To select the right pillar topics, start by thinking about the intersection of your business’s expertise and your audience’s interests. What high-level topics do your customers care about the most, and which of those topics are central to the products or services you offer? The ideal content pillar is one that aligns with your business goals and has enough depth to support many follow-up pieces.

Guidelines for picking pillar topics:

  • Relevance to your business and audience: Focus on core themes that reflect your brand’s expertise and the problems you solve, and make sure those topics are also things your customers actively want to learn about.
  • Sufficient breadth: Make sure the topic is broad enough to generate several cluster posts. If a topic only yields one or two subtopics, it might be too narrow to serve as a pillar.
  • Search potential: Use keyword research to gauge demand and competition. Aim for a broad keyword with solid search volume that isn’t so competitive it’s impossible to rank for.
  • Long-term value: Choose a theme that will stay relevant over time. Ideally, pick an evergreen topic you can update periodically to keep it valuable long-term.

Perform a content audit of your existing pages to spot natural pillar opportunities (you might find several posts that belong under one theme). Also consider your competitors: what broad topics have they covered, and where can you create something better or fill an unmet need? Remember, you don’t need a dozen pillars – start with a few core topics and cover them well.

“We advise businesses to select content pillars that hit the sweet spot between what your audience cares about and what your company specializes in,” says Emulent Marketing’s Strategy Team. “Your pillar topics should be the subjects for which you’d like to become the go-to source in your industry.”

Developing Effective Topic Clusters

With your pillar topics chosen, the next step is building out the topic clusters that support each pillar. Start by brainstorming and researching all the subtopics, questions, and tangents related to a given pillar theme. Keyword research tools are invaluable here: they can reveal common queries people search for within that broader topic. For example, if one pillar is “cybersecurity basics,” cluster topics might include things like “password management tips,” “how to spot phishing attacks,” “network security best practices,” and so on. Aim to cover the full spectrum of subtopics so that someone interested in your pillar will find answers to practically every related question on your site.

Quality is key for each cluster piece. These supporting posts should be detailed and genuinely helpful on their own – not just short fragments meant to funnel people to the pillar. Each cluster article takes one slice of the topic and explores it thoroughly, demonstrating your depth of knowledge. Also, try to include content for various reader intents – from introductory “what is” articles for beginners to more advanced how-tos or guides for those further along. Covering different intent levels ensures your cluster collectively appeals to a wide range of your audience.

Steps to build out your clusters:

  • Identify subtopics: List out all relevant subtopics under your pillar. Use tools (keyword planners, search suggestions, forums) to gather ideas on what information people seek about the main topic.
  • Audit existing content: Check if you already have articles or materials on these subtopics. You might update and repurpose some into cluster pages rather than starting from scratch for everything.
  • Prioritize by value: Decide which cluster topics to create first based on what’s most useful to your audience and what might drive SEO value. If certain questions are very common or certain long-tail keywords have good search volume, tackle those early.
  • Create high-value content: Write each cluster post to be the go-to resource on that subtopic. Include practical examples, data, or expert tips that make it stand out. This isn’t filler – it’s high-quality content that showcases your expertise. Aim to include a mix of introductory and advanced posts to serve readers at different knowledge levels.

You don’t have to publish every cluster article at once. Many companies release cluster content gradually – just be sure to link each new piece to the pillar as it goes live. Keeping a clear plan of all the subtopics you intend to cover will ensure you eventually build out a comprehensive cluster.

“Creating a topic cluster is about thoroughness,” the Emulent Marketing Strategy Team points out. “When someone lands on one of your cluster posts, they should immediately see that you have a whole library of content on that subject. That level of completeness builds trust with your audience and signals to Google that you’ve covered the topic from all angles.”

Internal Linking Strategy for Pillars and Clusters

Designing a good internal linking strategy is what ties your pillars and clusters together into a cohesive structure. It’s not enough to simply have related content – you need to connect the dots for both users and search engines. Make sure each cluster page links back to its pillar page, and that the pillar page links out to all of its cluster pages. This reciprocal linking is the backbone of the pillar-cluster model, creating a clear hierarchy where the pillar provides the overview and the clusters provide the details.

Use descriptive anchor text for your internal links (for example, use a phrase like Email Marketing Best Practices instead of a generic “click here”). This approach guides readers and helps search engines grasp the context of the linked page. You can also link between cluster pages where it’s relevant, to help users explore related information. Just ensure every internal link is purposeful and adds value for the reader.

Internal linking best practices:

  • Link pillars and clusters: Ensure there is two-way linking between your pillar page and each cluster page. Every cluster article should link back to the pillar, and the pillar page should link out to all its cluster articles.
  • Use meaningful anchor text: Hyperlink phrases that describe the destination. This not only guides readers but also helps search engines understand the relationship (e.g., a link saying “local SEO tips” pointing to an article about local SEO signals that connection).
  • Keep it natural: Blend internal links into your content where they fit naturally, rather than dumping a list of links at the bottom. Also avoid adding links that feel forced or unrelated; every link should be relevant and helpful to the reader.

A good internal linking structure also means any SEO authority one page gains (say your pillar receives some high-quality backlinks) can flow to the others. In effect, your pillar and its cluster articles help boost each other’s rankings. And from the user’s perspective, internal links keep visitors exploring your site rather than bouncing back to Google for more info. Internal linking is the glue holding your content cluster strategy together – when done right, it amplifies the impact of all your content efforts.

Frequently Asked Questions

  • What is a content pillar page? A content pillar page is a comprehensive, authoritative webpage that covers a broad topic in detail. It serves as the central hub in a topic cluster, providing an overview of the subject and linking to more specific related pages for deeper information.
  • How many cluster posts should each pillar have? There’s no fixed number, but most pillar pages are supported by several cluster posts – often anywhere from five to fifteen. The goal is to have enough cluster content to thoroughly cover the subtopics related to your pillar, without adding fluff.
  • Do I need to create all my cluster content at once? Not at all. You can publish your pillar page first and then add cluster posts over time. Just remember to link each new cluster page to the pillar as soon as it’s live. You can build the cluster gradually as long as you have a clear plan.
  • Can a small business use a pillar-cluster strategy effectively? Absolutely. Even if you don’t have a big content team, you can start with one or two core content pillars that are most relevant to your business and slowly build clusters around them. A focused, well-structured content cluster can help a smaller site compete with larger players in SEO.
  • How often should I update a pillar page? Review your pillar page a few times a year, and update it when there are new developments or insights. Keeping the content fresh maintains its authority and can positively impact rankings.
