Understanding Keyword Extraction for SEO
Keyword extraction is the process of identifying the most important terms and phrases in your content. It helps you understand what your content is about, what you're ranking for, and how to optimize for better search visibility.
Types of Keywords Explained
Primary Keywords
The main topic of your content. These are broad, high-volume terms that define what your page is about. Example: "keyword research" for an SEO guide.
Secondary Keywords
Supporting terms that complement your primary keywords. They add context and help search engines understand your content better. Example: "SEO tools", "search volume".
Long-tail Keywords
Specific, longer phrases (3+ words) with lower search volume but higher conversion rates. Example: "best keyword research tools for beginners".
LSI Keywords (Latent Semantic Indexing)
Semantically related terms that help search engines understand context. For "apple" these might be "iPhone", "MacBook" (technology) or "fruit", "orchard" (food).
Entity Keywords
Specific names of people, brands, places, or things. These help establish authority and topical relevance. Example: "Google Analytics", "New York".
Understanding Search Intent
Search intent reveals what users are trying to accomplish when they search for a keyword. Matching your content to search intent is crucial for ranking well.

How to Use Extracted Keywords for SEO
Optimize Title Tags & Meta Descriptions
Use primary keywords in your title tag (preferably at the beginning) and meta description. This improves click-through rates from search results.
Structure Your Headings (H1, H2, H3)
Place primary keywords in your H1 tag. Use secondary and long-tail keywords in H2 and H3 subheadings to organize content and signal relevance.
Natural Integration in Body Content
Sprinkle keywords naturally throughout your content. Use LSI keywords to add context. Avoid keyword stuffing—aim for 1-2% density for primary keywords.
Create Internal Links with Anchor Text
Use keywords as anchor text when linking to other pages on your site. This distributes link equity and helps search engines understand your site structure.
Identify Content Gaps
Compare your keywords to competitor content. Missing important terms? Update your content to be more comprehensive and topically relevant.
Keyword Mapping Best Practices
Keyword mapping is the process of assigning specific keywords to specific pages on your website. This ensures each page targets unique terms and prevents keyword cannibalization.
One Primary Keyword Per Page
Each page should target one main primary keyword. This creates focus and prevents pages from competing against each other in search results.
Group Related Keywords Together
Cluster related secondary and long-tail keywords around your primary keyword. Create comprehensive content that addresses all variations of user search queries.
Match Intent to Content Type
Informational keywords → Blog posts and guides. Transactional keywords → Product and landing pages. Commercial keywords → Comparison and review pages.
Create a Keyword Map Spreadsheet
Document which keywords target which URLs. Track search volume, difficulty, current ranking, and priority. Update quarterly as you create new content.
Frequently Asked Questions
What is the difference between keywords and key phrases?▼
Keywords are single words, while key phrases contain multiple words. In modern SEO, the distinction is less important. Search engines understand that "running shoes" is a single concept even though it's two words. Focus on targeting topics and user intent rather than individual words.
How many keywords should I target per page?▼
Target one primary keyword and 3-5 closely related secondary keywords per page. This allows you to create focused, comprehensive content without diluting your message. Long-tail variations of your primary keyword can naturally appear throughout the content.
What is keyword density and does it matter?▼
Keyword density is the percentage of times a keyword appears in your content. While it mattered in the past, modern search engines focus on context and natural language. Aim for 1-2% density for primary keywords and use synonyms and LSI terms naturally. Prioritize readability over hitting a specific percentage.
How do I find LSI keywords for my content?▼
LSI keywords can be found in several ways: Google's "People also search for" and related searches, autocomplete suggestions, and by analyzing top-ranking content for your target keyword. Our keyword extractor automatically identifies LSI terms in your existing content to show you what semantic relationships already exist.
Should I use the exact keyword or can I modify it?▼
Modern search engines understand variations and context. You don't need to use the exact match every time. Variations like plurals, verb tenses, and word order are understood by Google. Use the exact keyword in important places (title, H1, first paragraph) but vary it naturally throughout the content for better readability.
How often should I update my keyword strategy?▼
Review your keyword strategy quarterly or when you notice ranking changes. Search trends evolve, competitors change tactics, and user behavior shifts. Use tools like Google Search Console to identify new keywords you're ranking for, then optimize content to capture more of that traffic. Extract keywords from your top-performing content to understand what's working.
