HTML SEO: one h1 with the main keyword, descriptive title under 60 characters, unique meta description, alt text on all images, semantic structure, fast loading, and a canonical URL to prevent duplicate content.

SEO in HTML

  • One <h1> per page with your main keyword
  • Descriptive <title> tags (50-60 chars)
  • Unique <meta name="description"> (150-160 chars)
  • Descriptive alt text on all images
  • Semantic HTML — search engines understand structure
  • Fast loading — use lazy loading and optimised images
  • Canonical URL to avoid duplicate content
