How to Do Keyword Clustering: Complete Guide to Grouping Keywords
Understanding how to do keyword clustering is essential for creating an effective SEO content strategy.
In this lesson, you will learn how to do keyword clustering manually, leverage AI tools for faster results, and prioritize your keyword clusters for maximum impact.
Key takeaway
Keyword clustering groups related keywords by search intent, not just topic similarity.
Search intent comes in four types: Transactional (ready to buy), Commercial (comparing options), Informational (seeking knowledge), and Navigational (finding locations/brands).
High CPC indicates transactional value. Keywords with high cost-per-click show commercial intent and should be prioritized for revenue generation.
Clustering Methods
- Manual clustering gives you deep understanding: Use Find function to search keywords, group by intent similarity, and organize in spreadsheet clusters.
- AI clustering saves 70-80% of time: Use ChatGPT, Claude, or Grok with proper prompts, but always review and refine the results with human judgment.
- SERP validation confirms clusters: If the same pages rank for multiple keywords, those keywords belong in the same cluster.
Prioritization Strategy
- Green (Highest Priority): Transactional and product keywords that generate immediate revenue. Target these first.
- Yellow (Medium Priority): Commercial comparison keywords for users investigating purchases. Target after product pages.
- Purple (Lower Priority): Informational content that builds authority but doesn’t convert immediately. Target last.
- Use the simplified priority formula: Profitability → Volume → Difficulty → Existing Assets
What Is Keyword Clustering?
Keyword clustering is the process of grouping related keywords together based on search intent and topic similarity, allowing you to create comprehensive content that targets multiple keywords simultaneously.
Keyword clustering involves organizing your keywords into groups where each cluster represents a single topic or content piece. Instead of creating separate pages for closely related keywords, you group them together to:
- Create more comprehensive content
- Avoid keyword cannibalization
- Improve topical authority
- Maximize content efficiency
- Target multiple keywords with one page
What is search intent?
Before learning how to do keyword clustering effectively, you must understand search intent. Search intent refers to what the searcher is actually looking for when they type a query into Google.
What are the types of search intent?
1. Transactional Intent: These keywords indicate the user is ready to make a purchase:
- “Buy iPhone charger”
- “Fast charger for sale”
- “Best deals on wireless chargers”
How to identify: Look for high cost-per-click (CPC) values in your keyword data. High CPC indicates advertisers are willing to pay more because these keywords convert to sales.
2. Commercial Intent: Users are comparing options and investigating before purchase:
- “Best phone chargers in Nigeria”
- “iPhone charger vs Samsung charger”
- “Top 5 fast chargers”
How to identify: These often include comparison words (vs, best, top), have moderate to high CPC, and when searched, return product roundup pages.
3. Informational Intent: Users seek knowledge without immediate purchase intent:
- “How long do phone chargers last”
- “What is fast charging technology”
- “Are phone chargers AC or DC”
How to identify: Questions, “how to” phrases, low CPC values, and search results showing blog posts and guides.
4. Navigational Intent: Users want to find a specific webpage or brand:
- “Konga phones”
- “jumia Nigeria”
- “Apple store chargers”
How to identify: Brand names.
5. Local intent: Users want to find a specific location;
- Phone charger store near me
- Laptop store in Lekki
How to identify: Geographic terms, “near me” phrases, and local keywords.
Identifying each of these search intent makes it easy for you to know how to do keyword clustering.
Step-by-Step Guide: How to do keyword clustering manually
The process of learning how to do keyword clustering is a step by step process: prepare, identify, group, move, and multiply.
Step 1: Prepare your keyword list
Start with your compiled keyword research from Google Keyword Planner, Google Search Console, Ubersuggest and other sources. Ensure your spreadsheet includes:
- Keywords
- Search volume
- CPC (Cost Per Click)
- Paid difficulty
- SEO difficulty
Step 2: Identify your first cluster topic
Begin with a seed keyword and look for related terms. For example, starting with “fast charger”:
- Use the Find function (Ctrl+F or Cmd+F) to search for “fast” throughout your keyword list
- Review each keyword containing “fast” to determine if it shares similar search intent
- Create a new column titled “Topic cluster”, then add the topic label for this cluster (e.g., “Types of Fast Chargers”)
Step 3: Group Keywords by Search Intent Similarity
When learning how to do keyword clustering, the key is recognizing intent similarity. Group keywords where searchers want the same type of information:
Example Cluster: “Charging Safety”
- “Can a fast charger be used on other phones?”
- “Can fast charging damage battery?”
- “Does fast charging affect battery life?”
These keywords share the same intent: users concerned about charging safety.
Example Cluster: “Fast Charger Products”
- “Fast charger”
- “Best fast charger for [phone model]”
- “Fast charger price”
- “Buy fast charger online”
These keywords indicate transactional intent for purchasing fast chargers.
Step 4: Move Keywords to Their Clusters
In your spreadsheet:
- Add a new column called “Topic Cluster” or “Keyword Group”
- Label each keyword with its appropriate cluster name
- Physically move related keywords together by cutting and pasting rows
- Keep keywords that are members to the same cluster next to each other for easy reference
This manual process can be time-consuming but gives you deep understanding of your keyword landscape.
Step 5: Create Multiple Cluster Categories
Continue this process throughout your entire keyword list, creating clusters such as:
- Product-focused: “Fast Chargers,” “Wireless Chargers,” “Type-C Chargers”
- Educational: “Charger Technology,” “Charging Safety,” “Battery Care”
- Comparison: “Fast Charger vs Regular Charger,” “Best Chargers 2025”
- Local: “Phone Charger Stores [Location]”
Advanced Method: How to Do Keyword Clustering with AI
AI tools can dramatically speed up the clustering process. Here’s how to do keyword clustering using AI effectively.
Preparing Your Data for AI Clustering
- Copy your keyword data (keywords, search volume, CPC, difficulty scores)
- Limit to 500 keywords per batch for optimal AI processing
- Include all relevant metrics but remove unnecessary columns
The AI Clustering Prompt
Use this proven prompt structure (adaptable for ChatGPT, Claude, or Grok):
Act as an SEO specialist. Cluster the keywords below based on topic similarity. I want my answer in a table format with these columns:
1. Keywords
2. Topic Cluster (topic similarity group)
3. Search Volume
4. CPC
5. Paid Difficulty
6. SEO Difficulty
Ensure you cluster every keyword and don't neglect anyone. Don't change any of the data values - keep them exactly as provided.
Processing AI Results
After the AI generates your clustered table:
- Copy the output as CSV format
- Paste into your Google Sheets or Excel
- Review the clustering for accuracy
- Make manual adjustments where AI misunderstood intent
- Merge similar clusters that AI separated unnecessarily
AI Clustering Limitations
While AI is powerful for learning how to do keyword clustering quickly, it’s not perfect:
- Accuracy issues: AI may misunderstand search intent
- Over-clustering: May create too many small clusters
- Under-clustering: May group dissimilar intents together
- Context blindness: Doesn’t know your specific business offerings
Best practice: Use AI to do 70-80% of the work, then apply human judgment to refine the clusters, is the best way to learn how to do keyword clustering.

Keyword Prioritization: Which Keyword clusters do you target first?
Understanding how to do keyword clustering is only half the battle. You must also prioritize which clusters to tackle first. There are 3 ways you can prioritize your keyword clusters.
The Profitability Framework
Priority your clusters based on potential revenue generation:
Priority Level 1 (Green – Highest Priority)
- Product pages: Transactional keywords
- Category pages: Product category keywords
- High CPC keywords: Indicate commercial value
- Ready-to-buy intent: Users at decision stage
Priority Level 2 (Yellow – Medium Priority)
- Commercial intent: Comparison and “best of” keywords
- Investigation stage: Users researching options
- Moderate CPC: Some commercial value
Priority Level 3 (Purple – Lower Priority)
- Informational intent: Educational content
- Low CPC: Minimal immediate commercial value
- Top-of-funnel: Awareness stage content
Using color coding for visual representation of the priorities
In your spreadsheet:
- Highlight transactional clusters in green
- Mark commercial clusters in yellow
- Label informational clusters in purple
- Use blue for navigational/local keywords
This visual system makes it instantly clear which clusters demand immediate attention.
The RIPCOM Priority Formula
For advanced prioritization when learning how to do keyword clustering at scale, use the RIPCOM framework:
R – Relevance: How relevant is this cluster to your ecommerce products?
- Score: 1-5 (5 = highly relevant, 3 = fairly relevant, 1 = Not relevant)
I – Intent: What type of intent? (Transactional scores highest)
- Score: 1-5 (5 = transactional, 4 = commercial, 3 = Informational, 2 = Local, 1 = Navigational)
P – Potential Traffic: Expected traffic volume from cluster
- Score: 1-5 (5 = high volume, 3 = medium volume, 1 = low volume)
C – Competition: How difficult to rank?
- Score: 1-5 (5 = easy to rank, 1 = very difficult)
O – Opportunity: Do you already have relevant pages?
- Score: 1-5 (5 = page exists, needs optimization, 1 = no related pages available)
M – Momentum: Current ranking position if any
- Score: 1-5 (5 = already ranking on page 2-3, 1 = no webpage at all)
Calculate total score for each cluster and prioritize highest scores first.
Simplified Prioritization Approach
For most scenarios, use this simpler method:
- Profitability first: Which clusters generate revenue?
- Volume second: Among profitable clusters, choose higher volume
- Difficulty third: Among similar volume, choose easier to rank
- Existing assets fourth: Prioritize clusters where pages exist
What are the common keyword clustering mistakes to avoid
These are the mistakes to avoid when learning how to do keyword clustering.
Mistake 1: Mixing Different Intents
Don’t cluster “buy iPhone charger” with “how do iPhone chargers work.” These require completely different content types and page structures.
Mistake 2: Creating Too Many Clusters
Having 200 micro-clusters is counterproductive. Aim for substantial clusters that justify comprehensive content pieces.
Mistake 3: Ignoring Search Volume
A cluster with five keywords totaling 50 searches/month probably doesn’t justify dedicated content. Combine with related low-volume clusters.
Mistake 4: Over-Relying on AI
AI clustering is a starting point, not a finish line. Always review and refine AI-generated clusters with human judgment.
Mistake 5: Neglecting Keyword Difficulty
Don’t prioritize high-volume, high-difficulty clusters if your website is a new website. Quick wins from easier clusters build momentum and authority.
How to validate your clusters with SERP analysis
After learning how to do keyword clustering, validate your clusters by checking Google search results:
Manual SERP Check Method
- Search each keyword in your proposed cluster on Google
- Examine the top 10 results
- Ask: “Are the same or similar pages ranking for these keywords?”
- If yes: Cluster is valid
- If no: Split into separate clusters
