What Are Topic Clusters for SEO?


Have you ever wondered how some websites or web pages seem to rank for a crazy number of long-tail keywords? Or how can they provide such comprehensive info on certain topics without their content becoming scattered everywhere? The secret sauce they’re using is called “topic clusters.” So now, what are topic clusters?

Since consumers increase the usage of search engines by up to 20% each year, topic clusters become a powerful SEO strategy. It helps websites rank higher in search and improves the user experience. In this article, I’ll explain what topic clusters are, how to create them, and why they can hugely benefit any website’s organic traffic and visibility.

What Are Topic Clusters?

Simply put, a topic cluster is a group of closely related content centered around a main “pillar” topic. This pillar content dives deep into the primary subject matter. 

It then has various “subtopics” branching off from it that cover additional aspects, depths, or angles of the overarching theme. Imagine a topic cluster about dogs. 

The pillar page could be about “choosing the perfect dog breed.” Then, some related subtopics would include pages for “dog grooming,” “dog training,” “dog nutrition,” and so on. All the content is interconnected and complementary.

This clustering helps search engines understand the full context and scope of the information you provide on a subject. It shows in-depth coverage available and prevents topics from being siloed off independently. 

Topic clusters allow sites to rank under an overarching keyword theme for many specific queries.

How to Create Topic Clusters

Creating effective topic clusters requires proper planning and execution. Here are the basic steps to develop effective topic clusters:

1. Research and select a topic theme or keyword with enough search volume and interest from target users. Identify higher search engine rankings, high-intent themes, and competitive keywords related to your industry or business goals.

2. You can also utilize keyword research tools such as Ahrefs, SurferSEO, SEMRush, etc, to evaluate search rankings, demands, and keyword difficulties. Make sure to check top-ranking pages for popular questions and considerations.

3. Create an in-depth pillar page that establishes domain expertise on the core subject using visuals, structured data, and internal linking. Incorporate headers, images, videos, and structured data as applicable.

4. Brainstorm related subtopics and map them to the pillar. Keywords, keyword phrases, questions, and variations on the overarching theme make good subtopics. Filter the ideas to only the most applicable and queried variations.

5. Write unique, high-quality content for all subtopic pages while cross-linking them under the pillar for a cohesive experience and cross-linking related content clusters under the umbrella of the pillar topic.

6. Continuously update, optimize, and expand the clusters by adding new pages and refining old content. Monitor performance and feedback to prioritize enhancement efforts.

Find Keywords for Your Pillar Page

Use tools like keyword planner, SERP Analysis, or Answer The Public to find main, secondary, and long-tail questions commonly asked about the cluster’s primary topic.

Target LSI keywords as well to expand reach. Refine the pillar page around these high-intent queries using recommended structures like Problem-Solution or AIDA funnels.

Conduct a Content Audit

Review all existing pages to see how they could integrate into proposed clusters. Note any duplicate, thin, or irrelevant content to remove or consolidate.

To identify natural cluster formations or gaps requiring new pages, map existing content pages for strengths and weaknesses. This audit prevents wasteful duplication of effort.

Select Topics for Cluster Subpages

Potential subtopics emerge from related keyword research, existing content review, and brainstorming other angles on the pillar topic.

Select topically associated themes with intent volume that can each support an independent page. Leave room for future expansion.

Content Clusters Improve Keyword Research

With the pillar and initial subtopics mapped out, conduct in-depth keyword research on each. Use tools to find related questions, synonyms, and variants for specific keywords pertinent to that sub-element.

Target keywords in head, secondary, and tail terms to maximize coverage. Overlap found keywords where relevant between pages for coherence.

Identify the Main Topics and Subtopics

The core or “pillar” topic focuses on the primary subject or theme. Secondary subtopics represent various angles, aspects, common queries, or categories surrounding this central unifying concept that each merits dedicated pages. Map subtopics to cluster logically based on applicability and search demand.

Create Quality Content

Develop rich, informative content focused first on the pillar page using recommended structures like problem-solution or question-answer templates.

Strategize page layouts to highlight important information using visuals, headings, summaries, etc. Provide a similar top-notch experience on all subtopic pages.

Strategize your Subtopics

Group semantically related subsets of subtopics into discrete supportive sections within clusters. For example, a “dog breeds” cluster may have sections dedicated to popular purebreds, mixed breeds, hypoallergenic options, etc. Thoughtfully organize subpages for usability and flow.

Start With a Good Topic Cluster Template

For consistency, create a basic framework template to standardize relevant elements like headings, linked navigations, and modular components across pages.

Fill in content details iteratively. Template cluster prototypes before optimizing to maintain format uniformity as pages expand.

Find Keywords for Cluster Pages

Use the same keyword research techniques on individual subtopic pages as done for the pillar pages—Target micro-focused head, secondary, and long-tail keyword variations tailored to each element’s subject scope. Overlap general cluster keywords were prudent.

Content Strategy Playbook

Develop buyer personas and map ideal customer journey touches—position clusters at relevant stages. Choose a pillar based on goals.

Audit content and organize it into logical categories. Research gaps require new pages. Visualize clusters in site maps with relationships shown.

Create a Content Creation Strategy

After selecting initial cluster topics, build a production plan to maximize efforts. Schedule pillar/subtopic creation according to priority and deadlines.

Assign ownership and get stakeholder buy-in. Specify optimization cycles. Track results and continuously refine strategy based on analytics.

Map Your Existing Content into Your Topic Cluster

Perform an audit of all current website pages. Categorize by topic and remove outdated/duplicate pages. Analyze top performers and map them as cluster pillars/subtopics where applicable. Identify any existing gaps yet to be filled by proposed new clusters and pages.

Identify Content Gaps

Note any related topic areas left uncovered based on keyword or competitive research. Check if refinements could expand the coverage of existing clusters—markdown ideas for future cluster development to improve content offerings consistently.

Research Google Knowledge Graph

Study how Google maps entities, attributes, and relationships in industry taxonomies—mirror-relevant models.

Understand emerging taxonomy shifts. Keep pace with changes by continually refining cluster semantic representations over time.

Write Your Content Just Like How You Talk

Adopt a natural conversational style using contractions, pronouns, and varying sentence structures for readability. Explain concepts simply while maintaining an engaging, friendly, and enthusiastic tone to capture and retain reader interest.

Your writing style greatly impacts how engaging your content is for readers. Adopting a natural conversational tone makes topics more approachable and enjoyable to consume.

Employ contractions and pronouns like “I,” “you,” and “we” to connect with your audience on a personal level. Referring to “the reader” distances people. Just like natural speech, use short, medium, and long sentences for cadence.

Start some with conjunctions rather than repeating subject-verb patterns. Opt for a lighter, helpful style over stodgy prose. Make readers feel like you’re chatting with them versus lecturing. Use enthusiasm sparingly to maintain credibility.

Avoid jargon, acronyms, or complex technical explanations. Break down topics into easy-to-follow steps, examples, or metaphors for broad understanding.

Let some of your personality shine through with well-placed humor, opinions, or acknowledgment of weaknesses. Readers want to relate to real people.

Read your writing aloud to catch any awkward phrasing, run-on sentences, or irregular pacing. Pause and polish until it sounds natural. Add enthusiasm without hyperbole to engage readers. Be aware of cultural norms and sensitivity to controversial topics.
