Build Thematic Categories from Pillar Topics
I start by identifying one strong, high-intent pillar topic, then building out supporting subtopics based on related long-tail keywords, common questions, and semantic variations. I use tools like SEMrush, Ahrefs, or even Google's "People Also Ask" and related searches to understand how people are phrasing their queries. Then, I group those keywords into clear, thematic categories that naturally link back to the main pillar page.
For example, I once created a content cluster for a client in the legal sector around the pillar topic "Lasting Power of Attorney". The main page gave an in-depth overview, while cluster content covered subtopics like "How to choose an attorney", "LPA for property vs health", "Common LPA mistakes", and "Costs of setting up an LPA". Each article linked back to the pillar page and vice versa, creating a tightly interlinked structure.
The result? We saw improved dwell time, stronger internal linking, and a noticeable lift in rankings across all the LPA-related terms: especially the pillar page, which ended up on the first page for several competitive queries. It also helped signal topical authority to Google, making it easier for future related content to gain traction.
Combine Semantic Analysis with Search Intent
My preferred method for keyword clustering combines semantic analysis with search intent grouping. I use a comprehensive four-step approach: first, I gather related keywords using tools like SEMrush or Ahrefs, then analyze search volume and competition, group them by search intent (informational, commercial, transactional), and finally create topic-based clusters around pillar content.
The core principle is grouping keywords that share the same search intent and targeting them together on a single page, rather than spreading them thin across multiple pages. This method leverages Google's understanding of semantic relationships between terms.
**Real Example: Fitness Equipment Cluster**
I recently created a content cluster for a fitness client around "home gym equipment." Here's how it worked:
**Primary Pillar:** "Best Home Gym Equipment 2024" (targeting 8,900 monthly searches)
**Supporting Clusters:**
- Budget cluster: "cheap home gym equipment," "affordable workout gear," "budget fitness equipment under $500"
- Space-specific: "small home gym equipment," "apartment workout gear," "compact fitness machines," "home gym small spaces"
- Equipment-specific: "home gym dumbbells," "resistance bands home," "home treadmill reviews," "best home gym mirrors"
- Workout-focused: "home gym workout routines," "full body home workouts," "beginner home gym exercises"
**Results After 6 Months:**
- 340% increase in organic traffic for fitness-related terms
- Ranked #3 for primary keyword (up from page 4)
- Generated 18 supporting articles that all interlinked strategically
- Improved topical authority, with Google recognizing the site as comprehensive for home fitness
- Average session duration increased 45% due to internal linking
- 28% improvement in conversion rate from organic traffic
**Implementation Strategy:**
Each cluster page targeted 3-5 related keywords naturally within the content. I used schema markup to help Google understand content relationships and implemented strategic internal linking with descriptive anchor text.
**Key Success Factors:**
The cluster worked because each piece served different search intents while supporting the main topic. The pillar page became a comprehensive resource, while supporting content targeted long-tail variations. Internal linking between cluster pages created strong topical signals for search engines.
This topic-based optimization strategy aligns with how modern SEO focuses on topics rather than individual keywords.
Create User-Centric Content Clusters
For a client in the travel industry (Marco Vasco), I was tasked with building 30+ content clusters around their main travel destinations.
I experimented with several SEO tools like SEMrush to organize keywords into clusters, but ultimately, I decided to take a more organic, human-centered approach. I observed that while SEO tools can highlight interesting trends, they often lack the subtlety needed to target specific user intents in the travel niche.
Consequently, I brainstormed clusters based on the customer journey and drew inspiration from Lonely Planet's table of contents, which presents information in a user-friendly and intuitive manner. I combined traditional keyword research with mind mapping techniques and ultimately relied on only basic keyword search tools (Google Keyword Planner and KWFinder) and a free mind mapping tool (MindMup).
We developed SEO topic clusters for over 10 major destinations, each featuring 3 central pillar pages supported by 10 to 15 cluster pages — such as "Organizing a Trip to Japan," "What to Pack for Japan," and "Best Time to Visit Japan." In total, we created and optimized more than 400 pages around thoughtfully chosen keyword groups.
This hands-on yet strategic method not only strengthened our internal linking but also improved navigation and established the site as a go-to authority on the topic. The results were impressive: a significant 219% increase in organic traffic, 240% more ranking keywords, and a remarkable 300% boost in branded search traffic across the targeted clusters.

Group Keywords by Decision-Making Stage
My preferred method involves semantic mapping based on search intent rather than traditional keyword similarity. After analyzing thousands of search queries, I discovered that grouping keywords by user intent and decision-making stage produces far more effective content clusters than grouping by topic similarity alone. This approach considers what the searcher actually wants to accomplish rather than just what words they use.
For a financial services client, we created a content cluster around "retirement planning anxiety" rather than the broader "retirement planning" topic. The cluster included keywords like "am I saving enough for retirement," "retirement planning stress," and "how to know if retirement plan is working." This intent-based approach allowed us to create deeply relevant content addressing specific emotional and practical concerns rather than generic retirement advice. The cluster increased organic traffic by 156% within four months because each piece directly addressed distinct aspects of retirement planning anxiety, creating natural internal linking opportunities while comprehensively serving this specific user need.
Use Cosine Similarity for Keyword Clustering
I start with a messy keyword dump in Sheets, then run a cosine similarity script to see which phrases sit nearest each other in vector space.
This mathematical step groups terms that feel related even when the wording differs, like "solar battery cost", "price of home storage", and "Tesla Powerwall pricing".
I give each cluster a working label, check that the search intent is genuinely the same, and cull anything that looks like an outlier. What's left becomes one pillar page with a handful of tightly focused satellite articles.
I keep the internal links simple. Satellites point up to the pillar, the pillar sprinkles links back down, and everything in the group links sideways once if it makes sense.
The clearest win came from a solar client last year. We built a pillar called "Guide to Home Battery Storage" and four satellites covering costs, brands, installation, and government rebates by state. Overall, that cluster added just over 40 percent extra organic visits to the battery section and, more importantly, delivered eleven tracked quote requests in the first quarter, up from three in the previous one.
Address Core Pain Points in Content
I prefer to group keywords around core pain points rather than just search volume. For example, we created a content cluster focused on "freelance marketing talent" with a pillar page on hiring strategies. We supported this with posts on cost breakdowns, interview tips, onboarding checklists, and red flags to watch for. Each piece addressed a real question and linked back to the pillar page.
The result? The entire cluster began ranking, not just the main page. Google recognized the depth of content, and visitors stayed longer because every click led to more valuable information. This approach is less about manipulating the algorithm and more about genuinely being helpful.
Organize Around Technical Expertise
"Technical expertise clustering" revolutionized our memorial jewelry keyword organization by grouping terms around craftsmanship competency rather than traditional product categories. Instead of clustering keywords by jewelry types (pendants, rings, bracelets), we organized content around technical processes customers need to understand before making informed memorial jewelry decisions.
Our breakthrough cluster focused on "ash-setting security methods" containing 23 related keywords including "secure ash encapsulation," "memorial jewelry sealing techniques," and "cremation ash preservation methods." This cluster generated comprehensive content explaining our specialized techniques while naturally incorporating search terms customers use when researching memorial jewelry quality standards.
The cluster approach improved our organic rankings for 89% of targeted keywords while establishing authority for technical memorial jewelry queries.
The specific example that transformed our results was our "material durability cluster" connecting keywords like "memorial jewelry longevity," "sterling silver ash jewelry," and "weather-resistant memorial pieces." This cluster produced eight interlinked articles explaining material choices, maintenance requirements, and quality guarantees—creating comprehensive resources that demonstrated our technical expertise.
Organic traffic for this cluster increased 267% within six months while generating 43% more qualified consultation requests from customers specifically seeking durable memorial options. Technical expertise clustering works exceptionally well for specialized businesses where customer education directly influences purchase confidence and premium pricing acceptance.
Target Long-Tail Keywords for Pillar Topics
My preferred method for grouping keywords into content clusters begins with identifying a high-impact pillar topic that aligns with one of my brand's core offerings—such as "PR for female entrepreneurs"—and then building out supporting posts that target long-tail, intent-driven keywords. I use tools like Ubersuggest and AnswerThePublic to uncover questions and subtopics my audience is already searching for.
For example, under the pillar page "How to Get Press for Your Small Business," I built a cluster that included supporting blog posts like "Best PR Tools for Solopreneurs," "How to Write a PR Pitch That Converts," and "Top Press Mistakes to Avoid When You're Just Starting Out." This not only increased time on site and internal link engagement but also helped FemFounder rank on the first page of Google for multiple PR-related queries. The cluster method allowed me to own a full conversation thread, improve topical authority, and see a 40% increase in organic traffic to those pages within 90 days.
Chase Intent Not Volume in Clusters
Our go-to method for building content clusters at CoinTime is starting with a pillar topic, then branching out using a mix of Google's "People Also Ask," related searches, and GSC query data. We use tools like Ahrefs to identify keyword variations, but we don't chase volume; we chase intent.
For example, we created a Bitcoin ATM content cluster with the main guide targeting "How to Use a Bitcoin ATM," then built supporting articles like "Bitcoin ATM Daily Limits," "Are Bitcoin ATMs Safe?", and "Do You Need ID for a Bitcoin ATM?" Each post linked internally and pointed back to the main guide.
That cluster boosted topical authority fast. Our main guide moved from page 3 to page 1 in under 30 days, and collectively, the cluster brought in 4x more organic traffic than the standalone article did before.
Smart clustering isn't about stuffing links; it's about answering every logical follow-up your reader might Google next.
Group Keywords by Implementation Challenges
Group keywords around client implementation challenges rather than traditional topic clusters. Instead of organizing content by product features, we create clusters based on the specific problems prospects face when deploying AI in enterprise environments.
Our most successful cluster centers around "AI model deployment challenges" and includes keywords like "enterprise AI implementation timeline," "model version control," and "production AI monitoring."
Rather than separate articles for each keyword, we created a comprehensive deployment guide that addresses all these concerns in a logical sequence.
This approach improved our SEO performance because search engines recognize that users searching for "AI deployment timeline" also need information about version control and monitoring. Our comprehensive resource now ranks for multiple related terms because it genuinely serves the complete user intent.
The business impact was substantial - prospects who found us through any keyword in this cluster convert at higher rates because they get complete implementation guidance rather than fragmented information.
This content cluster generates qualified leads who are actively planning AI deployments rather than just researching general concepts.
The method works because we organize content around user journeys rather than arbitrary keyword groupings.
