# SEO Optimizer

Comprehensive guidance for search engine optimization across content, technical implementation, and strategic planning to improve organic search visibility and rankings.

## When to Use This Skill

Use this skill when:
- Optimizing website content for search engines
- Conducting keyword research and analysis
- Implementing technical SEO improvements
- Creating SEO-friendly meta tags and descriptions
- Auditing websites for SEO issues
- Improving Core Web Vitals and page speed
- Implementing schema markup (structured data)
- Planning content strategy for organic traffic

## 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

<title>Ultimate Guide to React Hooks - Learn useEffect & useState</title>

<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

<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.">

<meta name="description" content="React Hooks guide and tutorial">
```

**Header Structure:**
```html

<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

<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

### 4. Technical SEO

  "image": "https://example.com/images/react-hooks.jpg",
  "datePublished": "2024-01-15",
  "dateModified": "2024-02-01",
  "author": {

**First Input Delay (FID) - Target: < 100ms**

**Cumulative Layout Shift (CLS) - Target: < 0.1**
- Set size attributes on images and videos
- Avoid inserting content above existing content
- Use transform animations instead of layout-triggering properties
- Reserve space for ads and embeds

**Page Speed Optimization:**
```html

<link rel="preload" href="/fonts/main.woff2" as="font" crossorigin>

<link rel="preload" href="/styles/non-critical.css" as="style" onload="this.onload=null;this.rel='stylesheet'">

<script src="/js/analytics.js" async></script>
<script src="/js/main.js" defer></script>
```

### 6. Mobile SEO

**Mobile-First Optimization:**

**Viewport Configuration:**
```html
<meta name="viewport" content="width=device-width, initial-scale=1">
```

### 7. Internal Linking Strategy

**Best Practices:**
- Use descriptive anchor text (avoid "click here")
- Link to relevant, contextual pages
- Maintain logical hierarchy and flow
- Include 3-5 internal links per 1,000 words
- Update old content with links to new content

**Example:**
```markdown

```

| Angular   | Good        | Steep          | Mature    |

## Local SEO (for businesses with physical locations)

    "streetAddress": "123 Main St",
    "addressLocality": "San Francisco",
    "addressRegion": "CA",
    "postalCode": "94102"
  },

}
```

## Monitoring & Analytics

**Key Metrics to Track:**
- Organic traffic trends
