Link Building for SEO

Links are one of Google's top ranking factors. They serve as "votes of confidence" from one site to another. Both internal links and external backlinks play important roles in SEO.

Internal Linking

Links between pages on your own website:

// Good internal linking practices

// 1. Use descriptive anchor text
<Link href="/react/hooks">
  Learn about React Hooks  // Good
</Link>

<Link href="/react/hooks">
  click here  // Bad - not descriptive
</Link>

// 2. Link to related content contextually
<p>
  State management is crucial in React. While
  <Link href="/react/hooks">React Hooks</Link> handle
  local state, you might need
  <Link href="/state-management">global state solutions</Link>
  for larger apps.
</p>

// 3. Create topic clusters
// Hub page: /react (links to all React topics)
// Spoke pages: /react/hooks, /react/context, etc.
// Spokes link back to hub and to each other
