## SEO Fundamentals

### 1. Keyword Research & Strategy

**Primary Keyword Selection:**
- Focus on search intent (informational, navigational, transactional, commercial)
- Balance search volume with competition
- Consider keyword difficulty and ranking potential
- Target long-tail keywords for quick wins

**Keyword Research Process:**
```
1. Identify seed keywords from business objectives
2. Use tools to expand keyword list (Google Keyword Planner, Ahrefs, SEMrush)
3. Analyze search volume and difficulty
4. Group keywords by topic clusters
5. Map keywords to content types and pages
6. Prioritize based on potential ROI
```

**Content Optimization Formula:**
- Primary keyword: 1-2% density (natural placement)
- Include in: Title tag, H1, first paragraph, URL, meta description
- Use semantic variations and related terms
- Maintain natural readability (don't keyword stuff)

### 2. On-Page SEO

**Title Tag Optimization:**
```html
<!-- Good: Descriptive, includes keyword, under 60 characters -->
<title>Ultimate Guide to React Hooks - Learn useEffect & useState</title>

<!-- Bad: Too long, keyword stuffing, generic -->
<title>React Hooks Guide React Hooks Tutorial React Hooks Examples Learn React</title>
```

**Best Practices:**
- Keep under 60 characters (displayed in SERPs)
- Place primary keyword near the beginning
- Include brand name if space permits
- Make compelling and click-worthy
- Unique for every page

**Meta Description:**
```html
<!-- Good: Compelling, includes keywords, call-to-action, 150-160 chars -->
<meta name="description" content="Master React Hooks with our comprehensive guide. Learn useState, useEffect, and custom hooks with practical examples. Start building better React apps today.">

<!-- Bad: Too short, no value proposition -->
<meta name="description" content="React Hooks guide and tutorial">
```

**Header Structure:**
```html
<!-- Proper hierarchy -->
<h1>Main Page Title (Primary Keyword)</h1>
  <h2>Section Heading (Related Keywords)</h2>
    <h3>Subsection</h3>
    <h3>Subsection</h3>
  <h2>Another Section</h2>
    <h3>Subsection</h3>
```

**URL Structure:**
```
✅ Good URLs:
- /blog/react-hooks-guide
- /products/running-shoes
- /learn/javascript-async-await

❌ Bad URLs:
- /blog?p=12345
- /products/cat-1/subcat-2/item-999
- /page.php?id=abc&ref=xyz
```

**Image Optimization:**
```html
<!-- Optimized image -->
<img
  src="/images/react-hooks-diagram-800w.webp"
  alt="React Hooks lifecycle diagram showing useState and useEffect"
  width="800"
  height="600"
  loading="lazy"
/>
```

**Best Practices:**
- Use descriptive, keyword-rich alt text
- Compress images (WebP format preferred)
- Specify dimensions to prevent layout shift
- Use lazy loading for below-fold images
- Include captions when relevant
