## Step 1: Seed Keyword Generation

- Start with your core technologies (React, Node.js, Python, etc.)
- Add problem-solving terms (error, fix, debug, optimize)
- Include implementation terms (tutorial, guide, example, implementation)

## Step 2: Long-tail Keyword Discovery

- Use Google Autocomplete for "how to [technology]"
- Check "People also ask" sections
- Analyze competitor blog titles and headings

## Step 3: Search Volume Analysis

- Focus on keywords with 500+ monthly searches
- Consider keyword difficulty vs. your domain authority
- Prioritize keywords with clear commercial intent

## Step 4: SERP Analysis

- Check current ranking content quality
- Identify content gaps in existing results
- Analyze featured snippets opportunities

const keywordMap = {
  'react hooks tutorial': {
    searchVolume: 2400,

# Article Template Structure

## 1. Title Tag Optimization

- Include primary keyword within first 60 characters
- Make it compelling and specific
- Example: "React Hooks Complete Guide: useState, useEffect, and Custom Hooks (2025)"

## 2. Meta Description

- 150-160 characters including primary keyword
- Include a compelling reason to click
- Example: "Master React Hooks with practical examples. Learn useState, useEffect, and how to build custom hooks with real-world code samples."

## 3. Header Structure (H1-H6)

H1: Primary keyword-rich title
H2: Major section headers with related keywords
H3: Subsection headers with long-tail keywords
H4-H6: Detailed breakdowns and code examples

## 4. Introduction Structure

- Hook: Address a specific developer pain point
- Problem: Clearly define what the article solves
- Solution Preview: Briefly outline what they'll learn
- Keyword Integration: Naturally include primary keyword
- Length: 100-150 words optimal

// SEO-optimized code block structure
const codeBlockSEO = {
  // 1. Descriptive comments that include keywords
  structure: {
    beforeCode: '// React custom hook for API data fetching',
    inlineComments: '// Handle loading state for better UX',
    afterCode: '// This pattern improves React component reusability',
  },

  // 2. Complete, runnable examples
  completeness: {
    imports: '// Always include necessary imports',
    exports: '// Show how to export and use the code',
    context: '// Provide usage examples and real-world scenarios',
  },

  // 3. Progressive complexity
  progression: [
    '// Basic implementation first',
    '// Add error handling',
    '// Include advanced features',
    '// Show production-ready version',
  ],
};

## Technical Blog Internal Linking

### Link Clusters by Technology

- Create topic clusters around main technologies
- Link related tutorials and guides together
- Use descriptive anchor text with keywords

### Example Link Structure:

### Anchor Text Best Practices:
- Use descriptive, keyword-rich anchor text
- Avoid generic "click here" or "read more"
- Include technology names and specific topics
- Example: "Learn more about React custom hooks implementation"

  <h2>React Custom Hook Implementation</h2>

  <!-- Context before code -->
  <p>
    This custom hook demonstrates how to handle API data fetching with loading
    states and error handling in React applications.
  </p>

  <!-- SEO-friendly code block -->
  <pre><code class="language-javascript">
// useApiData.js - Custom React hook for API data fetching
import { useState, useEffect } from 'react';

const useApiData = (url) => {
  const [data, setData] = useState(null);
  const [loading, setLoading] = useState(true);
  const [error, setError] = useState(null);

  useEffect(() => {
    const fetchData = async () => {
      try {
        setLoading(true);
        const response = await fetch(url);
        
        if (!response.ok) {
          throw new Error(`HTTP error! status: ${response.status}`);
        }
        
        const result = await response.json();
        setData(result);
      } catch (err) {
        setError(err.message);
      } finally {
        setLoading(false);
      }
    };

    fetchData();
  }, [url]);

  return { data, loading, error };
};

export default useApiData;
  </code></pre>

  <!-- Usage example -->
  <h3>Usage Example</h3>
  <pre><code class="language-javascript">
// Using the custom hook in a React component
import useApiData from './hooks/useApiData';

const UserList = () => {
  const { data: users, loading, error } = useApiData('/api/users');

  if (loading) return <div>Loading users...</div>;
  if (error) return <div>Error: {error}</div>;

  return (
    <ul>
      {users?.map(user => (
        <li key={user.id}>{user.name}</li>
      ))}
    </ul>
  );
};
  </code></pre>

  <!-- Explanation after code -->
  <p>
    This implementation provides reusable data fetching logic that can be used
    across multiple React components, improving code maintainability and
    reducing duplication.

  <h2>How do React Hooks work?</h2>
  <p>
    React Hooks are functions that let you use state and other React features
    without writing a class component. They allow you to:
  </p>

  <ul>
    <li>Manage component state with useState</li>
    <li>Handle side effects with useEffect</li>
    <li>Create reusable logic with custom hooks</li>
    <li>Access context with useContext</li>
  </ul>

  <p>Here's a basic example of using React Hooks:</p>
