What Are Related Keywords?
Related keywords are terms that are semantically connected to your main keyword. They share topical relevance and are often searched by the same audience. Unlike simple keyword variations or synonyms, related keywords expand the context of your topic and help you understand the full landscape of a subject.
For example, if your seed keyword is "email marketing," related keywords might include "newsletter software," "email automation," "drip campaigns," "subscriber engagement," and "open rate optimization." These terms don't necessarily contain the phrase "email marketing," but they're part of the same topic ecosystem.
Search engines like Google use semantic understanding to connect related concepts. Content that comprehensively covers related keywords signals topical authority, which can improve rankings for your primary keywords as well as help you rank for the related terms themselves.
How to Use Related Keywords
Build Topic Clusters
Group related keywords around pillar content. Create a comprehensive pillar page for your main keyword, then build supporting articles for each related term. Interlink them to create a topic cluster that signals authority to search engines.
Expand Content Naturally
Use related keywords as H2/H3 sections within your content. This helps you cover a topic comprehensively while naturally including semantically relevant terms. Each section can target a different related keyword.
Find Content Gaps
Identify related keywords you haven't covered yet. These represent opportunities to expand your content and capture additional search traffic. Compare your content inventory against the related keywords list.
Target Lower Competition
Some related keywords may have lower competition than your main keyword. Start ranking for these to build authority before targeting harder terms. This creates a foundation of topical relevance.
Improve Existing Content
Use related keywords to audit and improve existing content. Add sections covering related topics you've missed. This can breathe new life into underperforming pages and capture additional search queries.
Plan Internal Linking
Related keywords show you how topics connect. Use this to plan strategic internal links between pages. Link from pages about related keywords to your main pillar content to distribute page authority.
Best Practices for Related Keywords
Prioritize by Search Volume and Relevance
Not all related keywords are equal. Prioritize those with meaningful search volume and high relevance to your business. A highly relevant keyword with 100 searches may be more valuable than a loosely related keyword with 1,000 searches.
Create a Content Map
Organize related keywords into a visual content map showing how topics connect. This helps you plan which content to create and how pages should link together. Tools like spreadsheets or mind maps work well.
Match Intent for Each Keyword
Related keywords often have different search intents. Check the SERP for each keyword to understand what content type Google rewards. Some may be informational (blog posts), others commercial (product comparisons), or transactional (product pages).
Use Natural Language Integration
Include related keywords naturally, not forcefully. Modern search engines understand synonyms and context. Write for humans first, and the related keywords will fit naturally if you're covering the topic comprehensively.
Track Rankings for Related Terms
Monitor rankings not just for your primary keyword but for related keywords too. Comprehensive content often ranks for dozens of related terms. Track these to measure true content performance and find optimization opportunities.
Common Related Keyword Mistakes
Keyword Stuffing Related Terms
Don't force every related keyword onto one page. This leads to unnatural, poor-quality content that hurts rankings. Each page should have a clear focus. Spread related keywords across multiple pages in a topic cluster.
Ignoring Search Intent Differences
Two related keywords may require completely different content. "What is email marketing" needs a definition, while "email marketing software" needs a product roundup. Always check intent before combining keywords.
Creating Thin Content for Each Keyword
Don't create a separate 500-word article for every related keyword. This creates content cannibalization and thin content penalties. Group similar keywords and create comprehensive, in-depth content.
Forgetting Internal Links
Creating content for related keywords without linking them together wastes the cluster's potential. Search engines use internal links to understand topic relationships. Build strategic internal links between all related content.
Not Updating Related Keyword Research
Related keywords change over time as industries evolve. New products, trends, and terminology emerge. Refresh your related keyword research annually to ensure you're covering the current topic landscape.
Practical Examples: Related Keyword Strategies
Example 1: SaaS Company Building Topic Authority
Seed keyword: "project management"
Pillar page: "The Complete Guide to Project Management"
Supporting articles from related keywords:
- "agile project management" → How to Implement Agile Methods
- "project timeline" → How to Create Effective Project Timelines
- "team collaboration" → Best Practices for Team Collaboration
- "gantt chart" → Gantt Charts Explained: A Beginner's Guide
Strategy: The pillar page targets the head term while supporting articles target related keywords. All articles link back to the pillar, building topical authority.
Example 2: E-commerce Category Expansion
Seed keyword: "hiking boots"
Main category page: "Hiking Boots"
Sub-category pages from related keywords:
- "waterproof hiking boots" → Dedicated sub-category
- "lightweight hiking boots" → Dedicated sub-category
- "hiking socks" → Cross-sell category
- "ankle support hiking" → Buying guide blog post
Strategy: Related keywords reveal product sub-categories and related products to stock. Blog content addresses buyer concerns from informational related keywords.
Example 3: Service Business Local SEO
Seed keyword: "personal injury lawyer"
Main service page: "Personal Injury Attorney [City]"
Practice area pages from related keywords:
- "car accident lawyer" → Dedicated practice area page
- "slip and fall attorney" → Dedicated practice area page
- "workers compensation" → Related practice area page
- "personal injury settlement" → Educational blog content
Strategy: Related keywords reveal specific case types to create dedicated landing pages for. Each page targets users with specific legal needs.
Frequently Asked Questions
What's the difference between related keywords and long-tail keywords?▼
Related keywords are semantically connected terms that may or may not contain your original keyword. They expand the topic context. Long-tail keywords are longer, more specific phrases that usually include your main keyword as a subset. For example, "content strategy" is related to "content marketing," while "content marketing for small businesses" is a long-tail variation. You can have long-tail related keywords too.
How many related keywords should I target per page?▼
Focus on one primary keyword and 3-5 closely related keywords per page. Don't force all related keywords into one piece of content. Instead, use them to plan supporting content that links back to your pillar page. Each page should have a clear focus and intent match.
What does "relatedness" percentage mean?▼
The relatedness score indicates how semantically close a keyword is to your seed keyword. Higher scores (80%+) mean the keywords are very closely related and often appear in similar contexts or on the same pages. Lower scores indicate looser semantic connections—topics that are related but more tangential to your core subject.
Should I always target highly related keywords first?▼
Not necessarily. Consider both relatedness and competition. Sometimes moderately related keywords with lower competition can be better initial targets to build authority before tackling highly competitive, closely related terms. Also consider search volume and business value—a loosely related keyword with high buyer intent might be more valuable than a closely related informational term.
How do related keywords help with SEO?▼
Related keywords help SEO in multiple ways: (1) They help you create comprehensive content that signals topical authority to search engines. (2) They provide opportunities to rank for additional search queries. (3) They help you build topic clusters with strategic internal linking. (4) They improve content quality by ensuring you cover all aspects of a topic that users care about.
How are related keywords different from LSI keywords?▼
LSI (Latent Semantic Indexing) is a specific algorithm from the 1980s that Google doesn't actually use. The term is often misused in SEO to mean "related terms." Related keywords, as we use the term, are semantically connected terms based on modern NLP and user search behavior—a more accurate and useful concept for content optimization.
Can I rank for related keywords I don't specifically target?▼
Yes! This is one of the benefits of comprehensive content. When you write in-depth content covering a topic thoroughly, you often naturally include related terms and context. Google's semantic understanding allows you to rank for many related queries even if you never specifically optimized for them. Check Search Console for the "queries" report to discover which related terms your content ranks for.
