Keyword Placement and Optimization
Keyword strategy is more than repetition. Focus on intent, relevance, and natural integration.
- Primary Keyword: Page title, H1, first paragraph
- Secondary Keywords: H2/H3, body text, anchor text
- Long-tail Keywords: Target 3–6 word queries
- Semantic Keywords: Related terms to provide context
Example Cluster: Primary: What is SEO; Secondary: SEO basics, search engine optimization meaning; Long-tail: How does SEO work, SEO benefits for businesses
