You can write the best content in the world, but if Google can't render your JavaScript, it doesn't exist.

The Technical SEO Checklist

1. Meta Tags

Page Title - Brand

2. Open Graph (Social Sharing)

3. Semantic HTML

Use h1 for main title, nav for menus, article for content. Don't just use div for everything.

4. Robots.txt & Sitemap

User-agent: *
Allow: /
Sitemap: https://example.com/sitemap.xml

5. Server-Side Rendering (SSR)

For SPAs (React/Vue), ensure search engines see HTML, not just a blank body tag. Use Next.js or Nuxt.

6. Structured Data (JSON-LD)

Help Google understand your content (Products, Recipes, Events).
